JAKARTA (Reuters) - Indonesia's central bank said on Monday it would "intervene aggressively" in domestic foreign exchange markets when they reopen on Tuesday for the first time since new U.S. tariffs were announced.
Markets in Southeast Asia's largest economy 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.
