All 15 analysts in a Reuters poll predicted the central bank would keep its policy rate at 7.50 percent, where it has been since November.
Last year, between June and November, Bank Indonesia raised the rate by 175 basis points to battle inflation, support the rupiah and contain the current-account deficit.
On Thursday, the central bank also left the overnight deposit facility rate (FASBI) and lending facility rate unchanged at 5.75 percent and 7.50 percent respectively.
