The IMF Created SDR 456 Billion in a Single Day. It Was Divided by Shareholding, and the United States Received SDR 79.5 Billion of It.

On 23 August 2021 the International Monetary Fund performed an act that has no real analogue elsewhere in public finance: it created an international reserve asset out of nothing and credited it to every one of its members at once. The Board of Governors had approved it three weeks earlier, on 2 August. The amount was SDR 456,485.3 million, worth roughly US$650 billion. “This is a historic decision — the largest SDR allocation in the history of the IMF and a shot in the arm for the global economy at a time of unprecedented crisis,” the Fund's Managing Director, Kristalina Georgieva, said in the announcement of the approval.

The interesting part is not the size. It is the distribution rule, which is fixed, mechanical, and has nothing to do with who needed the money.

What a Special Drawing Right actually is

The IMF is unusually direct about what the SDR is not. It is not a currency. It is not, despite widespread belief, a claim on the IMF. The Fund describes it as a potential claim on the freely usable currencies of IMF members: a holder who wants actual money exchanges SDRs with another member, either by voluntary arrangement or, failing that, under a designation mechanism. Its value is defined by a basket of five currencies — the US dollar, the euro, the Chinese renminbi, the Japanese yen and the pound sterling.

That basket is reviewed on a five-yearly cycle. The IMF Executive Board concluded its most recent quinquennial valuation review on 14 May 2022, with the resulting currency amounts taking effect on 1 August 2022. The announcement of that review, PR22/153, described the change only in direction and not in figures: the updated basket implied slightly higher weights for the US dollar and the Chinese renminbi and, accordingly, somewhat lower weights for the British pound, the euro and the Japanese yen. No numeric weights were given in the release.

Free money, with an asterisk

An allocation is not a loan and carries no conditions — no programme, no review mission, no policy commitments. But it is not costless either, and the reason is a piece of double-entry bookkeeping that most coverage of the 2021 allocation skipped.

When SDRs are allocated, each participant receives two things at once: an interest-bearing SDR holding, and a corresponding long-term liability to the SDR Department equal to its cumulative allocation. Interest accrues on both. A country that leaves its allocation untouched has holdings exactly equal to its allocation, and the two interest streams offset one another, leaving only a small assessment toward the SDR Department's operating expenses. A country that exchanges its SDRs for dollars — which is the entire point for a member short of reserves — drops its holdings below its allocation and, on the Fund's own description, incurs a net interest obligation on the difference.

The rate is not set by committee. The IMF determines the SDR interest rate weekly, each Friday, as a weighted average of representative interest rates on three-month debt in the money markets of the five basket currencies. When those rates were near zero, the cost of spending an allocation was close to nothing. When they are not, it is not.

Divided by quota

Here is the rule that shaped the 2021 allocation. General allocations go to every member that participates in the Special Drawing Rights Department — all 190 members, on the IMF's 2021 allocation page — in proportion to their existing quotas in the Fund. Quotas are the Fund's shareholding: they determine voting power, borrowing access and, by the same arithmetic, the size of an allocation. The 2021 allocation was equal to 95.8455025357 per cent of each member's quota as of 2 August 2021.

The published country table is the clearest statement of what that means in practice. The United States received SDR 79,546.2 million. Japan received SDR 29,540.1 million, China SDR 29,216.5 million, Germany SDR 25,527.9 million, and France and the United Kingdom SDR 19,317.8 million each. The IMF's table gives amounts, not shares; on our own arithmetic against the published total of SDR 456,485.3 million, the United States line is about 17.4 per cent of the allocation, and those six lines together — SDR 202,466.3 million — come to roughly 44.4 per cent of it.

Further down the same table: India received SDR 12,569.6 million, Nigeria SDR 2,352.5 million, Ethiopia SDR 288.2 million, Chad SDR 134.4 million and Malawi SDR 133.0 million. The Marshall Islands received SDR 4.7 million and Tuvalu SDR 2.4 million.

The reason it works that way

The quota rule is not an oversight. A general allocation requires an 85 per cent majority of the IMF's total voting power — and voting power is itself distributed by quota, so the members receiving the largest shares are also the members whose consent is indispensable. An allocation formula that redirected reserves toward the countries that needed them most would have to be approved by the countries it took them from. The proportional rule is what makes the instrument passable at all.

It is also, in the Fund's framing, what makes an allocation an allocation rather than aid. The stated purpose is to meet a long-term global need to supplement reserves, and reserves are held by central banks in rough proportion to the size of the economies behind them. Distributing by quota keeps the operation inside the logic of reserve creation rather than the logic of transfer.

Five allocations in fifty-five years

The 2021 operation is the fifth and last entry on the IMF's own list of allocations, and it dwarfs the other four. As that list stood in April 2024, the Fund had allocated a total of SDR 660.7 billion, equivalent to about US$935.7 billion: SDR 9.3 billion in yearly instalments across 1970 to 1972; SDR 12.1 billion in yearly instalments across 1979 to 1981; SDR 161.2 billion on 28 August 2009; a special one-time allocation of SDR 21.5 billion, worth about US$33 billion, on 9 September 2009 to bring newer members into the system; and SDR 456.5 billion on 23 August 2021.

Read that list and the pattern is plain. Nothing happened for nearly three decades between 1981 and 2009, and then the two largest allocations in the instrument's history arrived in 2009 and 2021, each in the aftermath of a global crisis. The SDR is not a working part of the monetary system in ordinary times. It is a mechanism that sits idle, is reached for in emergencies, and — because the rule that governs it was written to be acceptable to the members with the most votes — pours out roughly where the shareholding already is.
