How Does the IMF Finance Itself?

Source details

The IMF is described as "a credit union for countries" with a lending capacity of nearly $1 trillion.
The IMF pools member resources, charges interest to borrowers, and pays interest to creditor members.
The difference between borrower interest and creditor interest covers administrative costs associated with general, or non-concessional, lending.
The IMF also earns income from investments, which covers other administrative costs such as surveillance and capacity development.
The IMF does not require its members to make annual contributions.

Members are assigned individual quotas based broadly on their relative positions in the world economy.
Quotas determine each member’s financial deposit in the IMF, how much it can borrow, and its voting rights on the Executive Board.
The IMF is implementing a 50 percent quota increase under the most recent general review of quotas to ensure sufficient lendable resources.

All members initially deposit one-quarter of their quota in freely usable currencies.
Freely usable currencies today comprise the US dollar, the British pound, the euro, the Japanese yen, and the Chinese renminbi.
The one-quarter portion constitutes a member’s initial reserve tranche position; members receive a market-based interest rate on this position and can withdraw up to the full amount in case of a balance-of-payments need.
The remaining three-quarters of a member’s quota is deposited in its own currency, often as a non-interest-bearing promissory note.
The IMF draws on currencies of members included in the financial transactions plan when providing loans; such members convert their IMF deposit to one of the five freely usable currencies if needed.
Amounts lent by creditor countries are added to their reserve tranche positions and earn market-based interest.
In 2024, some 50 creditor countries received a total of about $5 billion in interest on the resources they had provided for non-concessional IMF lending.
The interest rate a borrower pays equals the interest rate the IMF pays to creditors plus a margin (currently, about half a percentage point per year).
Income from the margin helps cover administrative costs associated with IMF lending operations; any remaining surplus is typically put into IMF reserves to build precautionary balances.

No borrowing country has ever defaulted outright on its IMF loans; there have been cases of protracted arrears, especially during the 1980s debt crisis (there are none currently).
If a borrower falls behind on interest payments, the IMF’s burden-sharing mechanism covers shortfalls in income.
Under the burden-sharing mechanism, all creditor and debtor members provide temporary financing in equal amounts by:
- Reducing the interest rate creditors receive on their reserve tranche positions; and
- Increasing the interest rate debtors pay on their loans.
The sums provided under burden-sharing are refunded once the borrowing member pays its arrears.
IMF lending is characterized as a safe investment for creditor countries, who earn interest while bearing only a fraction of the risks.
Borrowing countries benefit from IMF program design and conditionality, safeguards assessments of central banks, access to affordable loans, and lower interest rates than would typically be available in private capital markets.
IMF lending reduces the risk of spillovers and crisis contagion by supporting balance-of-payments adjustment and preventing severe import cuts in crisis-hit countries.

The bulk of IMF lending is non-concessional (borrowers pay market-based interest).
The IMF provides concessional loans to its poorest members using resources voluntarily provided by richer members, pooled in the Poverty Reduction and Growth Trust (PRGT), which is separate from the IMF’s own balance sheet.
Members contributing to the PRGT decide whether to give a grant or make a loan.
Because concessional borrowers pay little or no interest, the difference between borrower payments and creditor receipts is covered by a subsidy account funded by voluntary member contributions and the IMF’s own resources.
IMF members recently decided to create a framework allowing them to allocate part of the surplus they receive from non-concessional lending to PRGT subsidies.
