Bitcoin as a Reserve Currency: How Realistic Is It?

Short answer: Bitcoin as a reserve currency like the dollar is not realistic for the foreseeable future: it swings too much, hardly any trade is settled in bitcoin, and under the IMF's rules it does not count as a currency reserve. What is realistic is a smaller role as a reserve asset alongside gold. The US, El Salvador and the Czech National Bank have made a start.

"Bitcoin will be the next world reserve currency." You hear this at conferences and read it in comment sections, usually without numbers. Here you get the numbers: what the world's central banks hold today, what a reserve has to be able to do, where bitcoin stands, and what price would result if bitcoin were worth as much as central banks' gold. And what all this means for you as a holder in euros or francs.

What is a reserve currency?

Central banks hold assets in foreign currencies and in gold. They use them to defend their own exchange rate, pay for imports in a crisis and show investors that the country can pay its way. Most of these currency reserves are held in other countries' government bonds.

A reserve currency is a currency that other central banks hold on a large scale. Since the Second World War the most important one has been the US dollar. It fills three roles at once: central banks park their money in it, commodities such as oil are traded in it, and companies and states around the world borrow in dollars.

A reserve asset is something else. Gold is the best example: no invoice is written in gold, yet central banks hold about 36’500 tonnes of it. Gold serves as an emergency fund that depends on no other state. When people say "bitcoin as a reserve currency", they usually mean exactly this role, not the dollar's.

What central banks hold today

Every quarter, the International Monetary Fund (IMF) collects data on the currencies in which central banks hold their foreign exchange reserves. At the end of June 2026 they totalled about $13.2 trillion.

Source: IMF, COFER database, as of Q2 2026 (published Sep 30, 2026), shares of allocated foreign exchange reserves.

On top of that comes gold: about 36’500 tonnes in the vaults of central banks and the IMF. At the gold price of Nov 12, 2026 ($3’885 per ounce), that is about $4.56 trillion, more than all the world's euro reserves combined.

Two developments matter. The dollar's share is slowly falling: from 71% in 1999 to 56.7% today. And central banks are buying more gold than they have in decades: about 675 tonnes in the first three quarters of 2026, by the World Gold Council's estimate. Both show that central banks are looking for reserves that do not depend on a single state.

Bitcoin as a reserve currency: the case for

Bitcoin has several properties central banks value in gold, and some that gold lacks:

1. No one's liability. Bitcoin is not a promise by a state or a bank. No issuer can debase or block it.
2. Fixed supply. There will never be more than 21 million bitcoin. On Nov 13, 2026, about 20.11 million existed; the supply grows by about 0.8% a year, gold's by about 1.7% through new mines. Why this scarcity matters is explained in the comparison What is good money?
3. Verifiable and mobile. A central bank can check its holdings itself on the blockchain at any time and move them across borders in minutes. Gold has to be weighed, assayed and flown around.
4. Big enough for a start. On Nov 12, 2026, all bitcoin together are worth about $1.44 trillion (€1.30 trillion or CHF 1.20 trillion). That is more than all the world's yen, pound or franc reserves.

Add to that the pressure on the classic reserve currencies. The US, the euro area and Japan carry large debt burdens that in the long run they can only carry through inflation. What that means for the value of their currencies is shown in the article Government debt and bitcoin.

The case against bitcoin as a reserve

The hurdles are just as clear. They are the reason almost no central bank holds bitcoin.

Sources: volatility calculated from daily prices (bitcoin: bitcoin-powerlaw.com daily data, gold and euro: Yahoo Finance), IMF BPM7, US Treasury (debt on Nov 10, 2026).

The volatility. In a crisis, a central bank must be able to deploy its reserves at full value. Bitcoin has lost about 43% since its record high on Oct 6, 2025. Gold is not stable either: it has fallen 27% since late January 2026, and central banks still stick with it. With this argument, SNB (Swiss National Bank) chairman Martin Schlegel rejected bitcoin as a reserve for Switzerland.

The rules. Since the IMF's new balance of payments manual (BPM7, March 2025), bitcoin counts as a "non-produced nonfinancial asset". Because nobody has to repay it, it is not a financial asset and cannot be counted among official currency reserves. A central bank can hold bitcoin, but it does not show up in the statistics as a reserve.

The size. The world's reserves are large, the bitcoin market is small. Even a small share would buy up a large part of all bitcoin. The worked example below shows how fast that happens.

The role in trade. For bitcoin to become a reserve currency like the dollar, companies would have to write invoices in bitcoin, oil would have to be priced in bitcoin and states would have to borrow in bitcoin. None of that is in sight. With volatility of 44% a year, no importer would sign a twelve-month contract in bitcoin.

Which central banks and states hold bitcoin

As of Nov 13, 2026, no major central bank holds bitcoin in its official reserves. What exists are first steps:

• United States: Since the executive order of Mar 6, 2025, federal bitcoin seized in criminal cases may no longer be sold and go into a Strategic Bitcoin Reserve. An estimated 328’000 BTC. The government has not bought any so far, and the reserve sits with the Treasury, not with the Federal Reserve.
• El Salvador: has bought one bitcoin every day since November 2022 and held 7’831 BTC on Nov 10, 2026.
• Czech Republic: Central bank governor Aleš Michl proposed in January 2025 to consider putting up to 5% of reserves into bitcoin. The board opted for a $1 million test portfolio outside the currency reserves, announced on Nov 13, 2025.
• Euro area: ECB President Christine Lagarde said on Jan 30, 2025 that she was confident bitcoin would not make its way into the reserves of the EU's central banks.
• Switzerland: A popular initiative meant to oblige the SNB to hold bitcoin reserves failed to gather enough signatures in May 2026.

All states together hold about 646’000 BTC, a little over 3% of all bitcoin, almost all of it from seizures. Who holds how much and where the coins came from is shown in the article Countries with bitcoin reserves. All holders with live figures are in the treasury overview.

Worked example: what bitcoin as a reserve would mean

The world's reserves, foreign exchange and gold together, are worth about $17.8 trillion. What happens if central banks shift a small part of that into bitcoin?

The second question turns the calculation around: what price would it take for all bitcoin to be worth as much as a given reserve?

Basis: about 20.11 million bitcoin on Nov 13, 2026, reserves and gold price as above, exchange rates of Nov 12, 2026. In this calculation the reserves stay the same size; in reality they grow.

The table does not mean central banks will put these sums into bitcoin. It only shows the orders of magnitude the comparison moves in. According to the Power Law model, bitcoin is on its way to growing into this league, whether central banks join in or not.

What this means for you as a bitcoin holder

Bitcoin doesn't need a central bank to work for you. You can already use it today the way central banks use gold: as a reserve that depends on no state. That is the real idea behind "bitcoin as a reserve", just on a small scale.

So don't buy on the hope that central banks will buy soon. Such news is rare, and so far it has been small: a $1 million test portfolio in the Czech Republic, one bitcoin a day in El Salvador. Plan with what you can control yourself.

1. Treat bitcoin as your own reserve. Set a fixed share of your wealth and keep it for years, like a central bank with its gold share.
2. Buy regularly. A savings plan takes away the bet on headlines, whether states happen to be buying or selling.
3. Hold it yourself. The advantage of a neutral reserve only applies if no one can freeze it. How to do that is in the guide How to store bitcoin safely.
4. Expect setbacks. The same volatility that deters central banks hits you too. Plan so that you can sit out a 70% decline.

Where bitcoin stands today relative to its long-term trend:

Bitcoin trades at 0.66 times the trend, in the Accumulation zone (0.62–0.79×) and about 7% above the floor. How the model is calculated and where its limits are is in the methodology and in the article Bitcoin Power Law explained.

Where price and floor could be at a date of your choice, for example 2029 or 2031, you can work out in the forecast:

Why savings in euros and francs lose value in the first place, and so need a reserve of their own, is explained in the pillar article Inflation and the loss of purchasing power. The academy covers the basics of money and bitcoin at your own pace under Understand & secure.
