Supply and price stability

The supply of the network coin affects its availability, purchasing power, market value and suitability for different network functions. It can also influence the incentives to spend, lend, invest or retain the coin.

A supply that grows much faster than demand can reduce the coin’s purchasing power. A supply that remains fixed or contracts while demand grows can cause appreciation and create an incentive to hold the coin.

The network must consider these effects alongside demurrage. Demurrage changes the cost of retaining a balance, while supply policy determines how the total number of coins changes.

A network can impose demurrage while maintaining a fixed, expansionary, contractionary or elastic supply.

Supply and circulation

The total supply describes how many network coins exist. The circulating or liquid supply describes how many are practically available for exchange and other uses.

A network may have a large fixed supply while only a small proportion is actively available. The remaining coins may be held in inactive wallets, committed to staking, locked as collateral or stored in contracts.

This means increasing the total supply does not guarantee greater circulation. Newly created coins may also be retained, particularly if holders expect them to appreciate.

Demurrage addresses this distinction by applying a cost to possession. It encourages existing coins to move or become available without necessarily changing the total supply.

A network can therefore use supply policy to influence the number of units and demurrage to influence the incentive to retain those units.

Price and purchasing power

The price of the network coin can be expressed relative to fiat currencies, tokens, goods and services. If one coin purchases more over time, its purchasing power has increased. If it purchases less, its purchasing power has declined.

Price changes reflect both supply and demand. A fixed supply does not guarantee a fixed price because demand can change. An expanding supply does not guarantee depreciation if demand grows even faster.

Network demand can change because of transaction activity, application adoption, financial liquidity, staking, speculation and confidence in the network’s future.

External conditions can also influence the price. Changes in national economies, regulation, interest rates and wider digital-asset markets may affect demand even when the network’s internal activity remains stable.

Supply policy is therefore only one influence on purchasing power.

Why price stability matters

Stable purchasing power makes an asset easier to use for payments, financial contracts and economic planning.

When prices are reasonably predictable, businesses can estimate future costs and revenue with greater confidence. Lenders and borrowers can enter longer-term agreements without one side receiving an unexpected advantage from large changes in the monetary unit.

Extreme appreciation benefits existing holders and lenders but increases the burden on borrowers. Extreme depreciation benefits borrowers relative to lenders but reduces the real value of savings and income denominated in the coin.

Volatility can also discourage use. If participants expect rapid appreciation, they may postpone expenditure. If they expect rapid depreciation, they may exchange the coin immediately after receiving it.

Stable prices therefore support the medium-of-exchange and store-of-value functions examined in the money section.

The network coin does not need to be the primary medium of exchange

Price stability is especially important for money used daily to price goods, services, wages and debts.

The network coin does not need to perform this role for every community using the network. Tokens can provide mediums of exchange with monetary policies designed for particular countries, regions or online communities.

This reduces the burden placed on the native coin. It can tolerate some gradual change in purchasing power without preventing the network from operating.

However, the coin still benefits from moderate stability. It may be used to pay transaction fees, compensate node operators, provide token-exchange liquidity and secure contracts.

Rapid price changes make these functions less predictable. Operators may not know whether rewards will cover their costs, borrowers may face unexpected repayment burdens and liquidity providers may experience frequent rebalancing.

The appropriate goal is therefore not necessarily perfect price stability. It is to avoid changes severe enough to weaken the coin’s operational and financial usefulness.

Demurrage and supply policy

Demurrage can operate independently of the total supply.

If collected coins are transferred to a treasury and spent back into the economy, the total supply remains unchanged. Ownership changes, but the number of coins does not.

If collected coins are burned, demurrage also creates a contractionary supply. The balance charge reduces private holdings, and the total number of units declines.

If the network creates new coins while collecting demurrage, the supply may expand even though individual balances are charged.

This flexibility allows the network to separate two questions. The first is how many coins should exist. The second is how costly it should be to leave those coins idle.

Combining both effects into one mechanism can make policy harder to interpret. If a network burns demurrage income, holders may lose units while the remaining supply appreciates because of increasing scarcity. The appreciation may partially offset the intended cost.

Transferring collected coins to a treasury preserves a clearer distinction. Demurrage influences retention, while a separate policy governs the total supply.

Contractionary supply

A contractionary policy reduces the total number of network coins over time.

Coins may be removed through transaction-fee burning, the burning of demurrage income or another protocol rule.

If demand remains stable while supply contracts, the value of each remaining coin is likely to increase. This can preserve or increase purchasing power for existing holders.

A shrinking supply may also limit some forms of borrowing and speculation because fewer coins are available. The resulting appreciation can make a demurrage charge easier to tolerate, as holders may still experience a positive real return despite losing units.

However, contraction directly conflicts with the objective of keeping the coin available. Fewer units must support the same or a growing amount of network activity.

High divisibility prevents the network from literally running out of usable denominations, but divisibility does not solve every economic problem. Users must still acquire the coin from existing holders, and expectations of appreciation may cause those holders to wait.

Contraction and storage incentives

A predictable reduction in supply can create a strong incentive to retain the coin.

If users expect each unit to become more valuable, they may postpone spending or providing liquidity. The reduction in available supply may then produce further appreciation.

Demurrage can offset this incentive, but the required rate may need to rise with expected appreciation. If the contractionary effect is strong, a low carrying charge may not produce a negative net return from holding.

This places the two policies in opposition. Contraction rewards retention through expected scarcity, while demurrage penalises retention through the recurring charge.

The network could increase the demurrage rate to restore balance, but this creates additional uncertainty and may make the combined policy difficult to understand.

A contractionary supply is therefore not the simplest way to support circulation.

Contraction and debt

A loan denominated in an appreciating coin becomes more expensive to repay in real terms.

The borrower must return the same nominal number of coins even though each coin purchases more goods and services than it did when the agreement began.

Lenders benefit from this appreciation, while borrowers carry the increased burden. The expectation of continuing appreciation may discourage borrowing or productive investment.

Interest rates can adjust to some expected price change, but accurately predicting long-term appreciation is difficult.

A contractionary network coin may therefore be less suitable for lending and long-term contractual obligations.

Governing contraction

A fixed contraction rate is relatively predictable. Participants know how quickly supply will decline and can incorporate the rule into their decisions.

However, it cannot respond to changing network demand. The supply may continue shrinking during a period when activity and demand are already declining.

A variable contraction rate is more flexible but requires a governance process or automated mechanism. The network must determine when contraction is appropriate and how large it should be.

This adds complexity to a global and mission-critical system. The network already needs to govern demurrage, fees and other parameters. A separate contraction policy creates another source of uncertainty.

For these reasons, contraction offers few advantages that cannot also be pursued through a fixed supply combined with demurrage.

Fixed supply

A fixed-supply policy keeps the total number of coins unchanged.

Coins collected through demurrage can be transferred to the treasury and returned to circulation without creating or destroying units. Node operators and funded contributors receive coins that already exist.

A fixed supply is the simplest policy to implement and explain. The network does not need continuing decisions about issuance or removal.

This predictability reduces governance and implementation risk. Participants can verify the maximum or total supply without relying on economic data, price oracles or discretionary decisions.

For a global network, simplicity is particularly valuable. A failure in the native coin’s monetary policy could affect every application.

Fixed supply and purchasing power

A fixed supply does not imply a stable price.

If demand for the coin grows while supply remains unchanged, each coin is likely to appreciate. If demand declines, it may lose value.

A growing network may create continuing appreciation because the same number of coins supports more users, applications and financial activity.

This appreciation preserves or increases purchasing power for holders. It also supports the coin’s market value and can strengthen the economic cost of attacking a proof-of-stake network.

However, appreciation encourages storage. Participants may prefer holding the coin to spending or providing it as liquidity.

Demurrage can counteract this incentive. If the coin appreciates by less than the carrying charge, the holder still experiences a negative net return from inactivity.

If appreciation exceeds the charge, holding may remain profitable. The network would then need to accept some retention, increase the demurrage rate or consider a limited supply expansion.

Fixed supply and financial use

An appreciating fixed-supply coin can be difficult to use in lending.

Borrowers repay increasingly valuable units, creating a real cost beyond the stated interest or fees. This can discourage loans denominated in the network coin.

Price appreciation also affects token-exchange markets. If the coin is paired with many tokens, the relative price of every pairing must adjust as the native coin gains value.

Gradual appreciation may be manageable, but rapid changes increase volatility and the risk faced by liquidity providers.

The network coin does not need perfect stability, but excessive appreciation can weaken the secondary functions intended to create long-term demand.

Fixed supply as a starting point

Despite these limitations, a fixed supply is a strong starting point because it minimises systemic complexity.

A new network has limited data about long-term demand, velocity and the effects of demurrage. Introducing a complex supply mechanism before these relationships are understood creates unnecessary risk.

A fixed policy allows the network to observe how demand develops while concentrating on the design of its carrying charge and incentives.

If appreciation later becomes persistently disruptive, the community can consider an expansionary or elastic policy. Such a change should require strong evidence that the benefits exceed the additional risks.

Expansionary supply

An expansionary policy increases the total number of network coins over time.

New coins can be distributed to node operators, transferred to the treasury or allocated through another protocol mechanism.

Expansion may occur at a fixed rate or vary according to governance decisions and economic conditions.

If the coin’s supply grows at approximately the same rate as demand, expansion can reduce appreciation and support more stable purchasing power.

For example, if network demand grows persistently while supply remains fixed, prices denominated in the coin may fall. A modest increase in supply can accommodate some of the additional demand and reduce the rate at which the coin appreciates.

This can improve its suitability for lending, liquidity and collateral.

Expansion and network growth

A growing network may require more active coin balances. More users need to pay fees, more applications require liquidity and more operators may need compensation.

A fixed supply can support this activity through increased divisibility and velocity, but persistent demand growth may still cause substantial appreciation.

A low and predictable expansion rate can distribute new units as the network grows. If the rate remains below demand growth, the coin can continue appreciating, but at a slower pace.

This may provide a compromise between fixed supply and full price targeting. The policy does not attempt to respond to every market change, but it reduces the long-term scarcity effect.

The appropriate rate would depend on network growth, which cannot be known with certainty in advance.

Expansion and treasury income

Newly created coins can provide income for the network treasury.

The treasury can use them to compensate node operators, maintain the protocol and fund development.

This can reduce the need for transaction fees or a higher demurrage charge. However, issuance dilutes existing holders. The treasury receives purchasing power partly because the relative share represented by existing balances declines.

The value created through treasury expenditure must therefore justify the dilution.

If funded work increases the usefulness of the network faster than supply expands, holders may still experience appreciation. If expenditure produces little value, expansion may reduce purchasing power without generating corresponding benefits.

The quality of the funding process is therefore central to the potential effectiveness of expansionary issuance.

Expansion and demurrage

Expansion and demurrage can both discourage holding, but they do so differently.

Expansion may reduce the purchasing power represented by each unit when supply grows faster than demand. Demurrage reduces the number of units held while allowing the value of each remaining unit to stay stable.

Combining a high expansion rate with a high carrying charge can make the coin significantly less attractive than alternative assets. Users may hold tokens and obtain the network coin only when needed.

If expansion is used primarily to moderate appreciation rather than deliberately cause inflation, the rate should remain conservative.

Demurrage can then address low-cost storability directly, while expansion limits persistent scarcity-driven price increases.

Risks of expansion

The principal risk is that supply grows faster than demand.

Existing holders then lose purchasing power. Node operators and treasury recipients may sell newly created coins, increasing market pressure.

Rapid or unpredictable issuance can undermine confidence. Participants may be unwilling to hold or accept a coin when they cannot estimate how much the supply will expand.

Expansion can also reward politically influential groups if the distribution of new coins is governed poorly. Operators, treasury applicants and existing institutions may compete to capture issuance.

A fixed expansion rate avoids some discretion but cannot respond to periods of contraction. A variable rate is more responsive but introduces greater governance complexity.

Fixed-rate expansion

A predetermined expansion rate is relatively simple and predictable.

Participants can calculate future supply without relying on external data. The network can direct new coins towards node operation and treasury funding according to published rules.

The limitation is inflexibility. Demand may grow faster or slower than expected, and the same expansion rate continues through each condition.

A conservative rate that remains below expected long-term demand growth can reduce the risk of inflation. However, it may not prevent substantial appreciation during rapid growth or depreciation during contraction.

Fixed-rate expansion therefore offers moderate flexibility without attempting precise price stability.

Elastic supply

An elastic policy allows the total supply to expand and contract according to rules, data or governance decisions.

The objective is usually to align supply more closely with demand. If demand grows, the network creates additional coins. If demand falls, it removes coins or reduces issuance.

In theory, a sufficiently accurate elastic policy could maintain more stable purchasing power than fixed or predetermined supply mechanisms.

This could improve the coin’s use in transaction fees, lending, exchange liquidity and collateral. Borrowers and lenders would face less uncertainty, while node operators could estimate the purchasing power of future compensation more reliably.

The difficulty is determining how much demand has changed and how supply should respond.

Global economic complexity

A globally adopted network coin is affected by many economies and applications.

Different regions can experience expansion and contraction at the same time. One country may face falling demand while another experiences rapid growth.

The network coin still has one global supply and market price. It cannot independently stabilise purchasing power for every local economy.

At best, an elastic policy can respond to an aggregated or average measure of demand. Local prices may remain unstable even when the global average appears stable.

This is one reason tokens are more suitable for community-specific monetary systems. They can respond to narrower economic conditions without requiring the native coin to manage the entire global economy.

Measuring economic demand

An elastic supply mechanism requires data. The network must identify changes in demand and determine whether those changes are temporary, speculative or connected to real economic activity.

Possible measures include transaction activity, the coin’s price, financial liquidity, collateral use, active users and wider economic indicators.

Each measure has limitations and can potentially be manipulated.

A mechanism depending on one data source is particularly vulnerable. Participants who understand the rules may create artificial activity that causes a beneficial supply change.

Using several measures can reduce dependence on one signal, but it also makes the mechanism more complex and difficult to verify.

Transaction data

Transaction volume is visible on-chain, making it an attractive input for an elastic policy.

However, a participant can create multiple wallets and transfer assets between them. Low network fees can make artificial volume inexpensive.

The nominal value of token transfers is also unreliable. Anyone can create a token, distribute it across controlled wallets and assign it an apparent value through a thin or manipulated market.

An increase in transaction count does not necessarily mean demand for the network coin has increased. Users may submit more transactions while requiring very little coin for each one.

A transaction-based supply rule could therefore create new coins in response to activity that provides little economic value.

The network could make manipulation more expensive by ensuring that the possible benefit from changing supply is lower than the cost of generating the required activity.

This would reduce the attack incentive but also make the policy respond slowly to genuine growth.

Network-coin price

The market price of the network coin could provide information about changing demand.

If the price rises, the network might create additional coins. If it falls, it might reduce issuance or remove units.

However, the price must be measured relative to something. On-chain token markets can be manipulated, particularly when liquidity is limited.

A participant can create a token, control its supply and trade it against the network coin to produce an artificial price.

Using major fiat currencies or commodities requires external data. An oracle must report the relevant prices to the network.

Oracle failure or manipulation could then influence the coin supply. Because the native coin is mission-critical, this creates a systemic risk.

Price data can contribute to analysis, but relying on it as the sole automatic input is dangerous.

Financial metrics

The proportion of supply used as liquidity, collateral or staking may indicate changes in demand.

If participants voluntarily commit more coins to these functions, the asset may be becoming more desirable. A persistent decline can indicate weakening demand or an excessive carrying charge.

These metrics are available on-chain, but they can still be manipulated. Participants may move liquidity between protocols or create positions designed solely to influence the rule.

A supply adjustment may also be the wrong response. A decline in liquidity might require different incentives rather than the creation or removal of coins.

Financial metrics can support governance and analysis, but using them to control supply automatically requires careful protection against manipulation.

Active users

The number of active wallets is not a reliable measure of unique users. One person can control many addresses, while one application can submit transactions on behalf of many people.

An increase in active users also does not necessarily produce a proportional increase in coin demand. Transaction fees may decline at the same time, or wallet software may minimise the amount each user holds.

Active-user estimates can provide context but should not independently determine monetary expansion or contraction.

Wider economic data

Broader information about production, prices and economic growth would be useful for maintaining stable purchasing power.

Much of this information exists outside the Web3 network. It would need to be supplied through oracles, institutions or other external systems.

The data may be revised, delayed or calculated differently across countries. A global index would require decisions about which economies, goods and services receive greater weight.

The institutions selecting and maintaining the data could gain substantial influence over the network coin.

Using external economic data therefore introduces governance and security dependencies that conflict with the goal of a simple, independently verifiable protocol.

Governance complexity

An elastic supply can be managed through community governance rather than automatic rules.

Participants can evaluate economic conditions and vote on whether supply should change.

This allows human judgement to account for information an algorithm cannot interpret. However, it also makes monetary policy political.

Large holders may vote for policies that increase the value of their existing balances. Treasury beneficiaries may support expansion that provides more funding. Borrowers and lenders may favour different price outcomes.

Global participation makes decisions slow and difficult, while delegation to a small committee concentrates power.

A governance-based elastic policy can avoid some automatic manipulation but introduces discretion and conflicts of interest.

Implementation risk

A rule-based supply mechanism becomes part of the network’s core infrastructure.

An error can affect every holder, node operator and application. A manipulated input could create or remove large quantities of the coin.

The mechanism must operate correctly during market stress, when liquidity is limited and data sources may be unreliable.

Complexity increases the number of assumptions and possible failure points. A policy designed to improve price stability may weaken the entire network if its implementation fails.

An elastic policy should therefore be adopted only when its inputs and rules can operate with the reliability required of a mission-critical system.

Price stability versus protocol stability

Perfect price stability is not necessarily worth unlimited technical complexity.

The network coin can continue functioning while its purchasing power changes gradually. Applications can adjust fees, borrowers can choose other units and token money can provide greater stability for daily exchange.

A failure in the core protocol would be more damaging than moderate coin-price volatility.

Protocol stability should therefore take priority over precise price targeting. The network should not introduce systemic dependencies merely to eliminate every movement in market price.

This supports beginning with a simpler supply policy and accepting a degree of appreciation or depreciation.

Reducing short-term volatility

Long-term purchasing power and short-term volatility are related but distinct concerns.

Even if the network does not attempt to maintain a fixed long-term price, it can encourage deeper liquidity that reduces sudden market movements.

Token-exchange liquidity provides more buy and sell capacity. Larger transactions then have less effect on the coin’s price.

Lock-up incentives may also reduce abrupt withdrawals. If liquidity remains committed during periods of stress, markets can continue processing exchanges.

However, lock-up can reduce the number of coins holders can sell in response to new information. When the positions eventually unlock, delayed selling may still occur.

Liquidity incentives can reduce some forms of volatility, but they do not replace an appropriate supply and demand policy.

Demurrage and appreciation

The effective cost of holding the network coin depends on both demurrage and price appreciation.

If the coin appreciates by 5 per cent while the holder pays a 2 per cent charge, the holder may still receive an approximate net gain in purchasing power.

If appreciation is 1 per cent and demurrage is 3 per cent, inactivity produces a negative net return.

A fixed or contractionary supply may therefore require a higher demurrage rate during periods of rapid growth. An expansionary supply can reduce appreciation and allow a lower rate to produce the same net holding cost.

The relationship is difficult to manage precisely because future appreciation cannot be known in advance.

The network should examine longer-term trends rather than attempt to offset every short-term price change through the carrying charge.

Demurrage and inflation

An expansionary supply that exceeds demand growth reduces the purchasing power of each coin. Demurrage reduces balances independently of the unit’s purchasing power.

Applying both at high rates can impose a substantial combined cost. Users may receive fewer units over time while each remaining unit also purchases less.

This can weaken acceptance and cause participants to move into alternative assets.

A network using demurrage does not need to target continuing inflation merely to encourage circulation. The carrying charge already addresses the incentive to hold balances.

Expansion is more appropriately used to accommodate persistent demand growth or fund justified network expenditure rather than as a substitute for demurrage.

Selecting a starting policy

A new network operates under substantial uncertainty. It does not know its long-term growth rate, the sustainable demurrage rate or how users will divide holdings between the network coin and tokens.

A fixed supply offers the simplest starting point. It avoids dependence on manipulable economic data and reduces the number of governance decisions.

Demurrage income can be transferred to a treasury and spent without changing the total supply. The network can then observe the effects on demand, velocity and coin distribution.

If the coin appreciates gradually, the carrying charge can capture part of the resulting gain and discourage indefinite storage.

If appreciation becomes rapid enough to disrupt lending, liquidity and network access, a modest expansionary policy may become appropriate.

Moving towards expansion

A low and predictable expansion rate can reduce persistent appreciation without requiring the network to estimate every change in demand.

The rate should be conservative enough that it does not routinely exceed long-term network growth.

Newly created coins can be directed towards node compensation and treasury funding, reducing the need to increase transaction fees.

The network would then govern two economic parameters: the supply-expansion rate and the demurrage rate. Their combined effect must remain understandable.

Expansion should be introduced only when the problem created by fixed-supply appreciation is more significant than the additional complexity that the supply mechanism will introduce.

Moving towards elasticity

An elastic supply offers the greatest theoretical ability to maintain stable purchasing power but also introduces the greatest risk.

The network would need reliable indicators of global demand and rules resistant to manipulation. It would also need a legitimate process for changing those rules when conditions evolve.

As Web3 networks mature, better data and mechanisms may make this more practical. Historical information about transaction activity, liquidity, demurrage and price behaviour can improve understanding.

However, an elastic policy should not be adopted merely because it appears economically ideal. It must be secure enough for the network’s global and mission-critical role.

Until that threshold is met, accepting moderate price changes is safer than introducing a fragile stabilisation mechanism.

A staged approach

The appropriate supply policy may change as the network develops.

During the earliest phase, a fixed supply provides clarity and supports investment expectations. The absence or low rate of demurrage may make it easier to attract initial capital.

During a period of rapid growth, appreciation may support coin demand but also encourage storage. Demurrage can capture part of the gain and fund continued development.

As the network becomes larger and growth stabilises, a fixed supply may produce only moderate appreciation. In that case, there may be little reason to add supply complexity.

If demand continues expanding at a persistent and measurable rate, modest issuance can improve price stability. If growth becomes highly variable and reliable economic data becomes available, an elastic mechanism may eventually be considered.

The network’s development stage therefore influences the balance between investment, circulation, supply and demurrage.
