If the U.S. dollar stopped being the world’s leading currency, the most likely outcome is a gradual, uneven shift rather than a sudden break. The dollar’s international role is made up of separate functions, and those functions could change at different speeds. The IMF material available as of October 2026 does not quantify what such a change would mean for U.S. prices, savings, or borrowing costs, so the household effects described below are conditional channels, not forecasts.
What “world currency” actually covers
“World currency” is shorthand, and it hides more than it reveals. The dollar does several jobs in international finance: it is widely used to invoice trade, it makes up most of the foreign-exchange reserves that central banks hold, it is a common currency for borrowing and debt, it is involved in most foreign-exchange trades, and it settles many cross-border payments. Official reserves are the most frequently quoted measure, but they are only one row in that list.
| Role in international finance | Where the dollar stands | Source and date |
|---|---|---|
| Trade invoicing | Continues to dominate | IMF press briefing, February 19, 2026 |
| Official foreign-exchange reserves | About 58–59 percent of global reserves, at around that level since 2020 (COFER measure) | IMF press briefing, February 19, 2026 |
| International borrowing and debt | Continues to dominate borrowing; the IMF lists international loans and debt among areas of dollar dominance as of 2023 | IMF press briefing, February 19, 2026; External Sector Report, July 2025 |
| Foreign-exchange turnover | Listed among areas of dollar dominance as of 2023 | External Sector Report, July 2025 |
| Global payments | Continues to dominate | IMF press briefing, February 19, 2026 |
At the February 19, 2026 press briefing, IMF Communications Department Director Julie Kozack said the dollar “continues to dominate trade invoicing, international reserves, international borrowing, and global payments.” The position described in the table is broad. Reserve share is the most visible measure, but it describes central-bank holdings, not who invoices, borrows, or pays.
Reading the reserve figure
Before comparing reserve shares across years, three measurement points matter.

- Exchange rates move the numbers. Reserves held in other currencies are valued in dollars. When those currencies strengthen or weaken against the dollar, the dollar’s share can change even if no central bank bought or sold anything.
- The method has changed. In a note dated November 26, 2025, IMF staff members Glen Kwende and Erin Nephew introduced an imputed series that allocates reserves not previously assigned to a specific currency. The revised series allocates 100 percent of global reserves across currencies. That describes the method; it does not mean every central bank separately reported every currency holding. The IMF says overall trends remained broadly unchanged, with modest adjustments to shares.
- Coverage is broad but not complete. A June 11, 2024 IMF study by Serkan Arslanalp, Barry Eichengreen, and Chima Simpson-Bell reports 149 reporting economies representing 93 percent of global foreign-exchange reserves.
When you compare shares, use figures from the same dataset vintage and record the release date, because the series is revised.
How a change would probably unfold
There is no switch that turns reserve-currency status off. The international monetary system includes exchange arrangements, payment and transfer rules, capital movements, reserves, and official liquidity arrangements, and a decline in the dollar’s role would run through these unevenly. One plausible pattern is that reserve managers diversify first while companies keep invoicing and settling many transactions in dollars. That sequence is an illustration of how the functions separate, not an IMF forecast.

Why the dollar’s position has been sticky
The IMF’s July 2025 External Sector Report says: “The dollar’s dominance in the IMS has come about gradually and once established, has been remarkably resilient, underpinned by the strength of the US economy and the depth of its financial markets.” IMS refers to the international monetary system. The functions also reinforce one another. Broad dollar use in trade and payments makes dollar assets useful, and the availability of dollar assets and financing supports continued use. Because these functions feed each other, a lower reserve share should not automatically be described as the end of the dollar’s wider role.
Is there a successor currency?
The IMF material does not identify one. It compares candidates across distinct functions, and none matches the dollar across the board.

| Candidate | What the IMF evidence shows | Main limit |
|---|---|---|
| Euro | An established regional international currency and a distant second to the dollar across the major international functions the IMF compares | The comparison does not show it taking on the dollar’s full set of roles |
| Renminbi | Use has grown in some areas, supported by policy initiatives such as cross-border payment infrastructure and swap lines; IMF authors report that its reserve share declined after 2022 | Its role in international markets remains smaller than China’s economic footprint |
| Yen, pound, and currencies of smaller open economies | Part of the reserve mix; a 2024 IMF study finds that gradual reserve diversification has benefited nontraditional currencies rather than being matched solely by gains for the euro, yen, or pound | The diversification finding concerns reserve holdings, not the full set of international functions |
| Gold | Has gained central-bank attention | Does not by itself provide the payment, credit, and liquid-asset functions of a currency |
A future shift may therefore be distributed across several currencies and systems rather than amount to a direct handover to one.
Developments the IMF is monitoring
The IMF identifies three developments as worth watching. Each would affect a different part of the dollar’s role.

| Development | What it would affect | IMF assessment |
|---|---|---|
| Geopolitical fragmentation | Trade flows and the allocation of investment across geopolitical groups | The IMF documents trade fragmentation and reallocation of investment flows, but does not quantify consumer-price effects |
| Relative softening in the U.S. role as global banker and insurer | Demand for dollar-denominated assets and the terms of U.S. financing | Tentative indicators; the July 2025 analysis still describes the United States as the dominant provider |
| New cross-border payment systems and private digital assets | Routes and costs of cross-border payments, and the reach of dollar use | Dollar-backed stablecoins could reinforce dollar use, but their scale was modest compared with traditional dollar-denominated assets in the July 2025 report; wider retail adoption could create financial-stability risks |
In the July 2025 report, the IMF said none of these developments appeared set to alter the dollar’s central role at that time, citing the lack of a viable alternative and the unmatched depth of U.S. financial markets. The IMF presents that as an assessment, not a guarantee.

The IMF material does not provide a household forecast. It describes the channels a transition would run through, and the links from those channels to a family’s budget are conditional and unquantified.

- Modern coins and banknotes have changed dramatically over the last half century, and this collection features several items that were once commonly found in circulation but that have now disappeared and are increasingly hard to find. Together, they bring back memories of bygone days. The coins and banknote are widely sought-after for their timeless designs and compelling stories.
- One of America’s most beloved coins is the Lincoln Wheatback Penny that was last made over 60 years ago in 1958. The back features two stalks of wheat, while the obverse is a portrait of Lincoln that is still used today. The original Jefferson Nickel was minted in 1938 to honor Thomas Jefferson, third President of the United States from 1801-1809, and it was last made in 2003 when the design changed. The obverse depicts a portrait of Jefferson based on a bust made in 1789 by French sculptor Jean-Antoine Houdon.
- The Roosevelt Dime was first made in 1946 and continued to be made in 90% silver only until 1964 (over half a century ago). It honors President Franklin D. Roosevelt, who guided America through the Great Depression and World War II. The coin in this collection is 90% silver.
- The original Washington Quarter was first issued in 1932 to honor the 200th anniversary of George Washington’s birth. The same portrait by John Flanagan is still used today, but the reverse has been State Quarters and National Parks Quarters designs since 1999,
- The $1 Silver Certificate was last made in the Series of 1957, and until June 24, 1968, it could be redeemed for the actual silver with which it was backed and that was deposited in the United States Treasury. It features a blue Treasury seal, unlike the green seal on today’s paper currency, to identify it as a Silver Certificate.
Government borrowing and loan rates
A sustained decline in foreign demand for dollar assets could reduce one source of demand for U.S. government securities and change the terms on which the government finances itself. How far that would pass through to mortgage, auto, or credit-card rates is not established by the IMF material. Those rates depend on many factors besides Treasury borrowing costs, including monetary policy and lender pricing.
Exchange rates and everyday purchases
Exchange rates and international payment practices could adjust, changing the dollar price of imports and of spending abroad. The IMF documents trade fragmentation and reallocation of investment flows, but it does not quantify consumer-price effects from a change in the dollar’s status. Treat any specific claim about grocery, fuel, or travel prices as unsupported unless it comes from a separate source.
Savings and purchasing power
No source supports a number for how a transition would affect U.S. household savings, returns, or purchasing power. Do not assume a particular inflation rate, yield, or exchange-rate move from the headline alone. If you have a specific exposure, such as variable-rate debt, plans to spend abroad, or dollar-denominated savings you depend on, the relevant question is how that exposure is set up, not the broader currency story.
Signals worth tracking
The most recent figures cited here date from February 2026, so check the newest IMF release before relying on any of them. These are the signals the IMF material points to:
- Which function moves. A lower reserve share on its own is not evidence of a broader shift. Check trade invoicing, borrowing, and payment data alongside reserves.
- The latest COFER release and its method notes. Confirm whether the series has been revised since the November 2025 methodology change.
- Foreign demand for dollar assets and the IMF’s assessment of the U.S. global banker and insurer role in its External Sector Report.
- The scale of dollar-backed stablecoins relative to traditional dollar-denominated assets.
- Renminbi use in trade invoicing and in cross-border payment infrastructure.
The IMF data shows a dollar whose international role is broad and has been resilient, with gradual pressure on some functions and no established replacement. Whether that pressure grows is the open question, and it is one that current IMF material does not settle.
