Meaning

Key currency; reserve currency. A currency that is widely used in international trade, investment, and foreign exchange reserves, most notably the US dollar.

The 基軸通貨 underpins the global financial system — countries hold it as foreign exchange reserves and use it to price commodities such as oil. The US dollar has held this role since the Bretton Woods Agreement of 1944. The concept is central to discussions of exchange rate policy, currency wars, and geopolitical financial power. 基軸通貨国 (key currency nation) enjoys the 'exorbitant privilege' of borrowing cheaply on world markets.

Examples

1. 米ドルは依然として世界経済における基軸通貨としての地位を維持している。 The US dollar continues to maintain its position as the key currency in the global economy.
2. 基軸通貨国は通貨発行特権を持つが、それが財政赤字の拡大につながるとも指摘される。 Key currency nations hold the privilege of currency issuance, but this is also pointed out as a factor that can lead to expanding fiscal deficits.
3. 円が基軸通貨になる可能性は低いが、国際決済での利用は徐々に広がっている。 While the yen is unlikely to become a key currency, its use in international settlements is gradually expanding.
