From Indonesia to India, central banks in emerging markets face rising pressure to prop up currencies battling a surging U.S. dollar. Indonesia’s central bank has intervened in the currency and bond markets by a “sizable” amount, Governor Agus Martowardojo said in a statement overnight. Coordinating Economic Minister Darmin Nasution has called for calm over the rupiah weakening against the US dollar, saying that such a development has both a positive and negative impact. The Indonesian rupiah depreciated heavily against the US dollar on Friday amid the release of positive US economic data, a rise in the benchmark 10-year US bond yields, while the US Federal Reserve may remain on track to push for monetary tightening as concerns about geopolitical trouble and a global trade war ease.
