07 — If Bitcoin Were the Unit of the Economy: The Supply System, Fixed Versus Variable Rates, Backing, and How Denomination Would Shift

Three things people mean by "a Bitcoin standard"

A “Bitcoin standard” can describe at least three arrangements: Bitcoin as native base and unit of account; Bitcoin held as a public reserve asset beside an unchanged national accounting unit; or Bitcoin held privately for saving or investment. Conversion and credit questions depend most directly on the first, but reserve-backed claims can also add redemption risks. A U.S. order concerning eligible finally forfeited Treasury coins and the CNB's mixed-asset test outside official reserves do not establish that every asset manager proposes one regime or that public reserve use is already widespread. U.S. reserve order, §3; CNB test-portfolio release.

The supply system: what a fixed base does to an economy

Bitcoin's issuance schedule constrains its base-money creation; it does not determine broader Bitcoin-denominated claims or credit. The subsidy since the 2024 halving is 3.125 BTC per block, about 450 BTC per day at the target ten-minute interval, and is scheduled to halve again at block 1,050,000. The theoretical issuance ceiling is commonly rounded to 21 million BTC. That schedule is not a measurement of the coins accessible for spending or currently offered for sale. Bitcoin Core reports unspent-output value separately from provably unspendable amounts, but cannot identify every lost private key. Dormant outputs therefore cannot be netted into a defensible 16–17 million “effective supply” without an explicit, uncertain model. Bitcoin Core, `gettxoutsetinfo`.

Bitcoin fixes the issuance schedule of the base asset, not necessarily the quantity of bank deposits or other redeemable claims that people might use for payments. The quantity equation relates money, its velocity, prices and real output; a fixed base alone does not fix the other three. In a 2016 staff working paper, Warren Weber considered a hypothetical Bitcoin standard in which broad money growth tracks Bitcoin issuance, world output grows 2–3% yearly and velocity growth is near zero. Under those assumptions, he conjectured eventual 2–3% annual deflation; it is not a measured outcome or an unconditional forecast. His paper is the author's research, not Bank of Canada policy. Market credit conditions would matter for interest rates, and a redeemable central-bank or bank claim could support limited lending in a panic, constrained by its Bitcoin redemption promise. A pure Bitcoin-only system without such an issuer would have no central-bank lender of last resort. Weber, 2016, §§2–4, especially “Lender of Last Resort” and “Price Levels”; Federal Reserve, *Taylor Rules*, §2.

Some advocates distinguish productivity-driven price declines from debt-deflation under falling demand, and cite 1873–96 growth under gold or arguments about saving incentives. Those are interpretation and historical comparisons, not evidence that Bitcoin denomination would produce a harmless or desirable deflation rate. The former U.S./UK 1–2% historical price path and attributed advocate quotations need original series/page locators before they can support a measured analogy. Weber's Bitcoin result remains conditional on broad-money, output and velocity assumptions. Weber, 2016, “Price Levels”.

Debt-deflation is a conditional mechanism: falling prices can increase the real burden of fixed nominal debts and transmit distress through sales and credit. It does not follow that every future mortgage or wage would be written in Bitcoin or that wages could never adjust. Gold-standard recovery timing and gold supply responses require their own matched historical and production series before ranking a hypothetical Bitcoin regime. Bitcoin's base issuance does not respond to demand by discretionary policy, but bank claims, credit, velocity and market depth could change; fixed issuance alone cannot prove permanently higher volatility than gold. Weber, 2016, §§2–4; Bank of England, *Money creation in the modern economy*.

The word for what a fixed base lacks is base-money elasticity. A panic can raise demand for immediately spendable balances. Fractional-reserve institutions could issue redeemable Bitcoin-denominated deposits beyond their Bitcoin reserves, expanding deposit money and providing credit while adding run risk; Weber's imagined standard includes such liabilities and limited central-bank liquidity support. A full-reserve rule for transaction deposits would instead require one-for-one backing of those particular claims. It would not forbid lending existing Bitcoin through time deposits, bonds or non-bank funds, though those loans could have different liquidity and risk. Nor would it prove that all payment claims are safe: custody, operational failure and a false reserve statement remain possible. Lightning channels lock Bitcoin for channel capacity, and custodial balances depend on each custodian's actual assets and liabilities; neither is proof of a universal full-reserve banking system. The protocol's scheduled ceiling is not a ceiling on every measure of money or credit. Weber, 2016, pp. 8–12; Bank of England, *New forms of digital money*, §1.1 and box A.

Fixed rate or variable rate? The five regimes

A country adopting bitcoin as its monetary anchor can choose one of five arrangements, each with a historical precedent.

Fixed rate: regime (b), the classical-standard analogy. If each country promised to redeem its currency for a stated Bitcoin weight, the ratio of those weights would define the conversion parity. If one currency represented twice as much Bitcoin per unit as another, its parity would be two-to-one, not numerical equality. Low transfer costs could narrow deviations while redemption remained credible; access rules, fees and suspension risk would still matter. A trade deficit might drain reserves and constrain domestic credit, but the path from a reserve outflow to prices and employment would depend on banking behavior and policy. Weber's thought experiment argues that independent interest-rate policy would be tightly constrained and that limited emergency liquidity could remain; it does not establish the lifetime of a hypothetical regime. Weber, 2016, §§3–4 and exchange-rate discussion.

Redeemable claims: regime (c), an exchange-standard analogy. A Bitcoin reserve on an issuer's balance sheet is reserve holding; a legal and operational promise to deliver a specified Bitcoin amount on demand is convertibility. A claim can be partially reserved, fully reserved, or merely described as “backed” without an enforceable redemption right. Fractional reserves permit more claims than on-hand Bitcoin and can create run risk; they do not make a particular collapse inevitable. A Triffin-type tension would require the further design choice of a central issuer supplying international reserve claims while maintaining redemption. Which holders may redeem, at what rate, against which assets and under what suspension rules must be specified before drawing the Bretton Woods analogy. Weber, 2016, §§2–3.

Variable rate: regime (d), the floating reserve. An institution could hold Bitcoin at a floating dollar or other currency price without changing its unit of account. That is distinct from statutory tender or enforceable Bitcoin redemption. The former El Salvador 2022/2025 return percentages, CNB 5%-allocation volatility result, bill coin/lock-up targets and interested-industry compounding/debt-offset projections need their exact fiscal accounts, model pages, bill versions and assumptions before being used as observed results. The CNB's actual mixed-asset test is outside official reserves and is not a realised 5% allocation. CNB test-portfolio release.

Regime (e), the custodial Bitcoin claim. A fully reserved claim could be redeemable for a specified quantity of Bitcoin if its issuer actually holds sufficient unencumbered assets and permits withdrawal. The claim remains an issuer liability, not self-custodied Bitcoin; its holders face operational, legal and redemption risk alongside Bitcoin's price changes against the dollar. A one-for-one reserve rule limits uncovered claim creation but does not prevent credit financed by other instruments. This is a product design, not by itself a national monetary regime.

The comparison therefore depends on the arrangement: a Bitcoin-only unit, a national redeemable claim, a fractional-reserve issuer, a floating reserve holding and a custodial claim impose different constraints. A Bitcoin redemption promise may limit independent policy and expose an issuer to runs, but fixed parity does not mean one-to-one exchange, limited liquidity support is possible, and a historical analogy is not a forecast of inevitable abandonment. A floating reserve holding does not change a country's unit of account or create a Bitcoin standard.

How would everything come to be denominated in bitcoin?

One proposed framework orders monetary uses as collectible, store of value, medium of exchange and unit of account. Boyapati and Ammous use variants of that ladder to discuss Bitcoin, but it is not a universal historical sequence or a rule that every economy must climb in order. The observable question here is whether wages, debts, prices and taxes are actually stated in Bitcoin rather than translated from another unit at payment time. Four practical conditions are worth testing.

First, households and firms would need enough confidence in Bitcoin-denominated purchasing power to set multi-period prices and obligations; there is no universal 10% volatility threshold that decides this. Second, wages and debts would need to be contracted in Bitcoin at meaningful scale, not merely paid by converting a fiat amount. Third, tax obligations would need to be assessed in Bitcoin, rather than only allowing a Bitcoin payment against a fiat-calculated bill. Fourth, Bitcoin-denominated price, wage and lending data would be needed to assess whether it functions as an accounting unit. Divisibility into satoshis alone does not establish any of these changes.

Gresham's law describes incentives when an enforceable legal conversion ratio overvalues one of two monies; mandatory acceptance alone does not establish that condition. El Salvador's original Bitcoin law required acceptance in specified circumstances, but payments were valued against the dollar and the 2025 amendment made private acceptance voluntary. Its experience cannot be called a clean test of Gresham's law without establishing the operative conversion rule and behavior. Volatility, tax accounting, network access and preference for dollars are competing explanations to investigate. A voluntary shift toward Bitcoin denomination is possible in principle, but neither Gresham's law nor a “good money drives out bad” slogan proves that fiat must collapse first. El Salvador, Legislative Decree No. 199, arts. 1, 3, 7–8.

The history of dollarisation offers cases where a foreign unit of account followed earlier saving and payment use, but not a universal sequence for every country. Gita Gopinath's dominant-currency research explains how dollar invoicing, debt, hedging markets and reserves can reinforce its international position. The IMF warned in 2021 that wider stablecoin use could reinforce dollarisation; that was a risk analysis, not a finding that four named countries' crypto rails were mostly stablecoins. IMF, *Global Financial Stability Report*, October 2021, chapter 2. In Nigeria, a later IMF country report estimates that USDT and USDC made up over 65% of 2024 crypto inflows measured by its on-chain proxy. That does not contradict Chainalysis's 89% Bitcoin share of covered centralized-exchange fiat purchases; the flows and denominators differ. The cited material does not establish a comparable majority share for Argentina, Türkiye and Lebanon. IMF Country Report 26/125, annex VII, pp. 64–65; Chainalysis, 2025 Sub-Saharan Africa report.

This creates a question about denomination rather than a measured law of adoption. Dollar-denominated stablecoins are separate issuer claims used in parts of crypto trading and settlement; their use imports a dollar reference even when a transfer uses a crypto rail. Stablecoins are not all redeemable by every holder or backed by the same assets. The GENIUS Act establishes rules for specified U.S. payment-stablecoin issuers, with a conditional effective date; its July 2025 enactment did not itself license the whole stablecoin market. A Federal Reserve Board staff account of a July 2026 conference reports that several panelists argued stablecoin growth was likely to reinforce international dollar use; that attributed view is not proof that each additional Bitcoin transaction strengthens the dollar. To assess whether Bitcoin is becoming a unit of account, measure native Bitcoin prices, wages, debts and contracts separately from dollar-priced payments and trading pairs. BIS, *The future monetary system*, ch. III; enacted GENIUS Act, §§2–4, 20; Federal Reserve Board staff conference account, 16 July 2026.

One possible sequence for a shift toward Bitcoin denomination would begin with investment or reserve holding, then use as collateral or settlement, then native invoicing, and perhaps eventually wages, prices or taxes stated in Bitcoin. That is a scenario, not a necessary order of adoption or an observed national transition. Each proposed use needs its own contract, accounting and payment evidence; reserve holding alone does not prove later native denomination.

Key takeaways

A fixed Bitcoin issuance schedule does not fix broad money, credit, velocity or the price path. Weber's 2–3% deflation result is a conditional 2016 conjecture, not a measured consequence of putting prices in Bitcoin. Fractional-reserve payment claims could expand deposit money but invite runs; fully reserved transaction balances would constrain that form of creation without eliminating lending funded by existing savings. Distinct Bitcoin-only, redeemable-currency, floating-reserve and custodial-claim arrangements should not be collapsed into one “standard.” Conversion ratios depend on the promised Bitcoin weights; reserve holding, full backing and enforceable redemption are separate properties. Evidence for future denomination would have to include actual wages, debts, prices and taxes stated in Bitcoin—not an assumed volatility cutoff or inevitable fiat collapse.
