The central bank also held the deposit facility rate, or FASBI, and lending facility rate at 5.75 percent and 7.50 percent, respectively.

BI Governor Agus Martowardojo said the current-account deficit had narrowed to 1.98 percent of GDP in the fourth quarter.
All but one analyst in a Reuters poll had expected the bank to keep its reference rate on hold, due to recently positive trade data and a more stable exchange rate.
The G20 economy has kept its monetary policy tight to combat surging inflation and push down its current-account deficit, lifting the key reference rate a total of 175 basis points between June and November.
