What currencies are in the SDR basket?

Five currencies: the US dollar, the euro, the Chinese renminbi, the Japanese yen, and the pound sterling. The renminbi was added in 2016, making it the first emerging-market currency in the basket.

What are the current SDR weights?

From the 2022 review: US dollar 43.38%, euro 29.31%, renminbi 12.28%, yen 7.59%, and pound sterling 7.44%. Weights reflect the role of each currency in international trade and finance.

How often is the basket reviewed?

The IMF reviews the SDR basket every five years. The 2022 review took effect 1 August 2022, and the next regular review is scheduled for 2027 unless economic conditions trigger an earlier one.

How is the daily SDR value calculated?

Each currency contributes a fixed amount (not a fixed weight) to the basket. The IMF multiplies these fixed amounts by daily exchange rates against the dollar and sums them, so the live weights drift slightly from the review-date weights.

Is the SDR a currency I can spend?

No. The SDR is a unit of account and an international reserve asset held by IMF member countries, not a circulating currency. It can be exchanged among members for freely usable currencies.

The IMF Special Drawing Right (SDR) is an international reserve asset whose value is defined by a basket of five major currencies. This reference lists each basket currency with its official weight and the fixed currency amount used to compute the daily SDR value, based on the 2022 quinquennial review.

How it works

The SDR’s value is the sum of fixed amounts of five currencies, each converted to US dollars at the day’s market exchange rate:

SDR value (USD) = Σ ( fixed_amount_i × USD_per_unit_i )

The “weights” set at each review determine those fixed amounts. The IMF chooses amounts so that, on the day the new basket takes effect, the value share of each currency equals its assigned weight. Because the amounts are then frozen for five years, the live weights drift as exchange rates move.

Weights table

The 2022 review weights (effective 1 August 2022) are:

USD  43.38%   EUR  29.31%   CNY  12.28%   JPY  7.59%   GBP  7.44%

Notes and tips

Weights are derived from each currency’s share in world exports and in official reserves, foreign-exchange turnover, and international bank liabilities.
The renminbi (CNY) joined the basket on 1 October 2016, the first emerging-market currency to be included.
The fixed currency amounts — not the percentage weights — are what the IMF actually publishes for the daily valuation. This tool shows both.
The SDR interest rate (SDRi) is a separate, weekly-set figure and is not part of the valuation basket.
