What Are Special Drawing Rights and How Do They Work?

Special Drawing Rights are an international reserve asset created by the International Monetary Fund in 1969. They are not a currency anyone spends. An SDR is a potential claim on the freely usable currencies held by IMF member nations, and its value is pulled each day from a basket of five major currencies. Total allocations now stand at SDR 660.7 billion, roughly $936 billion. Countries hold SDRs alongside gold and foreign exchange as part of their official reserves, and when they need actual dollars or euros, they trade their SDRs for those currencies through the IMF.

What One SDR Is Worth

The value of an SDR is derived from a weighted basket of five currencies: the U.S. dollar, the euro, the Chinese renminbi, the Japanese yen, and the British pound sterling. In the IMF Executive Board’s most recent review, completed in 2022, the weights were set as follows:

  • U.S. dollar: 43.38%
  • Euro: 29.31%
  • Chinese renminbi: 12.28%
  • Japanese yen: 7.59%
  • British pound sterling: 7.44%

Those percentages translate into fixed currency amounts that stay constant through the review period: 0.59188 U.S. dollars, 0.36965 euros, 1.0879 Chinese yuan, 12.842 Japanese yen, and 0.078815 British pounds. Each business day, the IMF converts those amounts into U.S. dollars using spot exchange rates around noon London time and sums the result. That total is the day’s SDR value in dollars. As of late March 2026, one SDR was worth about $1.36.1International Monetary Fund. SDRs per Currency Unit and Currency Units per SDR

Because the currency amounts are fixed but exchange rates move, the effective weight of each currency drifts between reviews. The U.S. dollar and the renminbi both saw small weight increases in the 2022 review compared with 2015; the euro, yen, and pound saw modest decreases.2International Monetary Fund.

A currency has to clear two hurdles to enter the basket. The issuing country or monetary union must rank among the world’s top exporters of goods and services, and under rules dating to 1980 the basket includes the five members with the largest exports. A newcomer only displaces an existing basket currency if its exports exceed that currency’s by more than one percent.4International Monetary Fund. Criteria for Broadening the SDR Currency Basket The IMF must also determine the currency is “freely usable,” meaning it is widely used in international payments and actively traded on major exchange markets.5International Monetary Fund.

How Countries Receive SDRs

The IMF does not drip SDRs out continuously. Allocations happen in discrete rounds, and they have been rare. The 2021 allocation of SDR 456.5 billion, about $650 billion, was by far the largest in history and was approved in response to the economic fallout of the COVID-19 pandemic. It more than tripled total SDRs outstanding overnight. Before that, the biggest single round was SDR 161.2 billion in August 2009, during the global financial crisis. Earlier allocations in 1970โ€“1972 and 1979โ€“1981 were smaller, and a special one-time allocation in September 2009 of SDR 21.5 billion let countries that joined the IMF after 1981 receive their first allocation.6International Monetary Fund. Special Drawing Rights

Under Article XVIII of the IMF Articles of Agreement, a new general allocation requires the Managing Director to propose that a “long-term global need” exists to supplement reserve assets. That proposal must win an 85 percent supermajority of total voting power among SDR Department participants.7International Monetary Fund. Allocation of Special Drawing Rights For The Eleventh Basic Period Because the United States holds roughly 16 to 17 percent of total voting power, it effectively has a veto over any new allocation.

Once approved, SDRs go to every participating member in proportion to that member’s IMF quota, a share based on relative economic size. All 190 IMF members currently participate in the SDR Department.8International Monetary Fund. Questions and Answers on Special Drawing Rights (SDR) The quota formula means wealthy economies receive the largest allocations in absolute terms, which has been a persistent source of criticism since developing countries often need the liquidity most.

Turning SDRs Into Usable Currency

SDRs in a central bank’s account don’t pay for imports or service debt on their own. To use them, a country has to exchange them for hard currency through the IMF’s SDR Department.

Most of this happens through Voluntary Trading Arrangements. A VTA is a standing agreement in which a member country, or a prescribed holder, agrees to buy or sell SDRs within specified limits. As of August 2025, 41 VTAs were in place. When a country wants to sell, it submits a request to the IMF, which matches the seller with one or more VTA participants willing to buy. The IMF distributes transactions across VTAs using criteria designed to keep holdings balanced over time, including each participant’s ratio of SDR holdings to allocation and how far each VTA sits from its midpoint trading range. Settlement typically takes a few business days.9International Monetary Fund. Annual Update on SDR Trading Operations

If voluntary buyers can’t be found, the IMF has a fallback. Under Article XIX of the Articles of Agreement, the IMF can designate members with strong balance-of-payments positions and sufficient reserves to purchase SDRs from the requesting country in exchange for freely usable currency. Designated members are legally obligated to accept SDRs up to a ceiling, the point at which their SDR holdings reach twice their cumulative allocation.10IMF eLibrary. Article XIX, Section 5 Designation of Participants to Provide Currency The designation mechanism has not been activated in decades because the voluntary market works smoothly, but its existence is what keeps SDRs reliably liquid. Without it, a country holding SDRs would have no guaranteed way to convert them.

The SDR Interest Rate and Why It Matters

Every Friday, the IMF sets the SDR interest rate for the coming week based on a weighted average of three-month government debt yields from the five basket-currency money markets: U.S. Treasury bills, euro-area instruments, Chinese government securities, Japanese Treasury discount bills, and U.K. Treasury bills. For the week of May 4โ€“10, 2026, the rate stood at 2.742 percent. A floor of 0.050 percent prevents the rate from ever turning negative, even if underlying yields do.11International Monetary Fund. SDR Interest Rate Calculation

Each member earns interest on the SDRs it actually holds and pays interest on its cumulative allocation, the total amount the IMF has ever credited to it. If holdings and allocation are equal, the earned and owed amounts cancel out. Sell some SDRs for dollars, and your holdings drop below your allocation; you then pay net interest on the gap. A country that buys extra SDRs ends up with holdings above its allocation and earns net interest on the surplus.8International Monetary Fund. Questions and Answers on Special Drawing Rights (SDR) The rate is practically invisible to countries that sit on their allocations and never trade. It becomes financially real once a country converts SDRs into currency and starts running a negative net position.

That dynamic hit hard after the 2021 allocation. Many developing countries immediately exchanged their new SDRs for dollars to cover pandemic-related spending, pushing their holdings well below their allocations. Then global interest rates climbed. The SDR rate jumped from 0.05 percent in August 2021 to nearly 4 percent by mid-2023. An IMF working paper estimated that the net present value of charges for countries with negative SDR positions more than tripled over that period. By June 2023, 36 members owed SDR Department payments exceeding one percent of their GDP, and 45 had payment obligations topping 20 percent of their gross foreign exchange reserves.12International Monetary Fund. The Financial Cost of Using Special Drawing Rights: Implications of Higher Interest Rates The grant element of SDRs as a financing tool fell to 34 percent, just below the IMF’s own 35 percent concessionality threshold.

Where SDRs Show Up Outside Central Banks

SDRs also serve as a unit of account in dozens of international treaties and conventions. The most familiar example for ordinary people is the Montreal Convention governing international air travel. Airline liability limits are denominated in SDRs rather than any single currency, which keeps the limits from eroding whenever one country’s currency weakens.

As of late 2024, the Montreal Convention caps airline liability for passenger death or injury at 151,880 SDR (roughly $206,000), beyond which the airline can defend itself by proving it was not at fault. Liability for baggage destruction or loss is capped at 1,519 SDR (about $2,065), and passenger delay liability tops out at 6,303 SDR (roughly $8,570). The Universal Postal Union, various maritime liability conventions, and several other international organizations also use SDRs to express financial limits.13European Central Bank.

How the United States Manages Its SDRs

Within the U.S. government, SDRs are held and managed by the Exchange Stabilization Fund at the Treasury Department. SDR allocations appear as a liability on the ESF’s books, though repayment would only come due if the IMF canceled allocations, the U.S. withdrew from the SDR Department, or the IMF dissolved. Because the ESF’s holdings currently exceed its allocation, the fund receives net interest rather than paying it.14U.S. Department of the Treasury. Finances and Operations

Under 22 U.S.C. ยง 286p, the Secretary of the Treasury can issue Special Drawing Rights Certificates to the Federal Reserve in exchange for dollars. The Fed gives the ESF dollars; the ESF gives the Fed certificates backed by the SDR position. The dollar amount of certificates outstanding cannot exceed the value of the ESF’s SDR holdings. Treasury pays no interest on these certificates but has a standing agreement with the Fed to redeem them when the ESF’s dollar balances appear to exceed foreseeable needs.15Office of the Law Revision Counsel. 22 US Code 286p – Issuance, Purpose, and Redemption of Special Drawing Rights Certificates The mechanism lets Treasury convert an international reserve asset into spendable dollars without selling SDRs on the open market or reducing the U.S. position at the IMF.16U.S. Department of the Treasury.

Channeling SDRs to Countries That Need Them Most

Because the quota-based formula sends most SDRs to wealthy nations, the IMF has built two trust-based channels through which wealthier members can voluntarily lend their SDRs for the benefit of poorer ones.

The Poverty Reduction and Growth Trust provides concessional lending to low-income countries. Contributing members enter into loan agreements or note purchase agreements with the trust, with all transactions denominated in SDRs. Interest on these loans is typically paid at the SDR interest rate, though some agreements specify a lower rate. As of early 2026, 30 countries had channeled resources to the PRGT, mobilizing approximately $60 billion.17International Monetary Fund. Poverty Reduction and Growth Trust – 2023 Borrowing Agreements

The Resilience and Sustainability Trust, established more recently, channels SDRs toward low-income and vulnerable middle-income countries to help them address longer-term structural challenges such as climate change and pandemic preparedness. Its financial structure is designed so that contributors’ claims retain their “reserve asset character,” meaning the SDRs channeled through the RST still count toward the contributor’s reserves. As of early 2026, 23 countries had contributed, mobilizing roughly $49 billion.18International Monetary Fund. Resilience and Sustainability Trust Frequently Asked Questions

The combined $109 billion channeled through both trusts is a fraction of the $650 billion allocated in 2021. Proposals to channel SDRs through multilateral development banks have gained political attention, but as of early 2026, no member has agreed to do so.19United Nations Department of Economic and Social Affairs. 2026 Financing for Sustainable Development Report
