Indonesia's foreign-exchange reserves declined to the lowest level in April in nearly two years, as Bank Indonesia sustained interventions to defend the nation's currency, the rupiah.

Indonesia's foreign-exchange reserves fell to $146.2 billion last month, down from $148.2 billion in March, marking the lowest level of the international financial buffer since July 2024, reported Bank Indonesia. The reserve has fallen by $10.27 billion this year.

Bank Indonesia cited its "rupiah stabilization policy" in April, that is ongoing intervention in the foreign-exchange markets, for the shrinking foreign reserve position, with several other factors.

In general, Bank Indonesia has been spending US dollars in its foreign exchange reserve to buy and hold Indonesian rupiahs, thus increasing demand for the rupiah and the currency's relative scarcity, with the goal of undergirding the rupiah's value.

The Indonesian rupiah, which has been declining against the US dollar for several years, has lost 5% of its exchange rate against the greenback in the last 12 months, despite Bank Indonesia market interventions.

Indonesia's foreign-exchange reserves also slipped in April due to lower tax and services receipts, external debt repayments, as well as national government bond sales, added Bank Indonesia.

Although declining, Indonesia's foreign-exchange reserves remain adequate cover nearly six months of imports, which is above the benchmark of three months promoted by the International Monetary Fund (IMF).

Foreign-exchange reserves are assets held by a nation's central bank, generally denominated in US dollars or euros, including cash and non-domestic government bonds. Central bank gold hoards are also regarded as foreign reserves.

In addition to managing currency-exchange rates, an ample amount of foreign reserves can help a central bank buttress a nation's financial stability, by allowing national government to manage economic shocks and fund necessary imports in times of stress, such as oil.

Nations largely accrue foreign reserves by running trade surpluses, by inflows of money from offshore investments, by direct inward foreign direct investment, and by remittances sent home by offshore workers.
