Central-bank holdings
Monetary authorities hold reserve assets in multiple currencies according to liquidity, policy and risk-management needs.
Currency knowledge centre
Monetary authorities hold foreign exchange reserves for liquidity, intervention capacity and external obligations. The IMF's COFER dataset reports reserve holdings by currency at a global level. This hub focuses on five long-established reserve currencies: USD, EUR, JPY, GBP and CHF. Reserve use is only one part of a currency's role and does not turn a reference rate into an investment recommendation.

Topic definition
Reserve currencies are currencies held by central banks and other monetary authorities as part of official foreign exchange reserves. Authorities may use reserves to meet external obligations, support liquidity or conduct exchange-market operations under their own mandates. The IMF's COFER dataset reports the global composition of allocated reserves by currency. This hub focuses on five established reserve units, while recognising that official portfolios can include other currencies and that reserve status does not guarantee a fixed or stable exchange rate.

Economic role
Reserve currencies help monetary authorities manage external liquidity and diversify official assets. Their role is connected to deep financial markets, payment infrastructure and international invoicing, but the composition of reserves changes over time and differs by authority. COFER is the relevant global statistical source for aggregate reserve shares. A currency's presence in reserves describes institutional use; it is not a recommendation, a promise of stability or a substitute for examining the exchange-rate framework on the currency profile.
