Agencies, Jakarta – Bank Indonesia said on Monday it would "intervene aggressively" in domestic foreign exchange markets when they re-open on Tuesday for the first time since new US tariffs were announced.
Markets in Indonesia have been closed since March 28 for public holidays, and trading will resume on Tuesday, April 8. Before the break, the rupiah had already been under pressure, dropping to its lowest levels since the 1998 financial crisis.
Bank Indonesia said in a statement the intervention would come in the spot and non-deliverable forward markets, as well as in secondary bond markets, adding that it had already intervened offshore in Asia, European and New York markets.
"Bank Indonesia's series of measures are aimed at stabilising the rupiah exchange rate and maintaining the confidence of market participants and investors in Indonesia," the statement said.
It also said it will optimise rupiah liquidity instruments to ensure adequate liquidity in the money market and with domestic banks.
Global markets plunged Monday after China hammered the United States with its own hefty tariffs, ramping up a trade war many fear could spark a recession.
The central bank's board of governors agreed Monday to intervene in the offshore markets in Asia, Europe and New York to stabilise the currency, citing "intense global pressures" against the rupiah.
"Bank Indonesia will also intervene aggressively in the domestic foreign exchange markets... after opening on 8th April 2025, while purchasing government securities (SBN) in the secondary market," it said in a statement.
Trump's "Liberation Day" announcement saw the archipelago nation hit with an additional 32 percent levy on its goods, higher than the baseline 10 percent for all countries and more than Southeast Asian neighbours Malaysia, Singapore and the Philippines.
President Prabowo Subianto said Monday the country would negotiate with Washington to ask for a better deal.
The United States is one of Indonesia's top trading partners, and Jakarta enjoyed a $16.8 billion trade surplus with Washington last year, according to Indonesian government data.
Washington appears to have particularly taken aim at countries that the United States has a large trade deficit with.
Data from the US trade representative office shows Washington's goods trade deficit with Jakarta was $17.9 billion in 2024, up 5.4 percent on the year prior.
Cambodia, Laos and Vietnam were some of the worst-hit nations, being hit with tariffs of more than 40 percent.
