Bank Indonesia has raised its benchmark BI-Rate by 50 basis points to 5.25 per cent, delivering a larger-than-usual move as it moved to shore up stability. The decision was taken at the Board of Governors meeting held on 19 and 20 May 2026 and announced on Wednesday.

The Deposit Facility rate was raised by 50 basis points to 4.25 per cent and the Lending Facility rate by 50 basis points to 6.00 per cent, keeping the width of the interest rate corridor unchanged around the new policy rate.

CORRIDOR AND SRBI RATES MOVE HIGHER

Rates on Bank Indonesia's rupiah securities, known as SRBI, were also lifted in line with the policy tightening. The central bank said SRBI rates had been raised to 6.21 per cent, 6.31 per cent and 6.45 per cent across the various tenors, reinforcing the pass-through of the policy decision to short-term money market yields.

SRBI have become a central tool in Bank Indonesia's liquidity management framework, used to attract portfolio inflows and to help anchor the rupiah. Adjusting their yields alongside the policy rate is intended to keep them competitive with other short-term instruments and to preserve the rate premium the central bank is targeting. Rates on the three tenors of SRBI now sit at 6.21 per cent, 6.31 per cent and 6.45 per cent, extending the yield curve for short-dated rupiah paper offered by the central bank.

The 50 basis point step is larger than the standard 25 basis point increments Bank Indonesia has typically used in recent tightening phases, signalling a stronger response function to the pressures the Board of Governors described as requiring reinforcement of stability.

FOCUS ON RUPIAH AND FINANCIAL STABILITY

In framing the decision, Bank Indonesia said the rate move was aimed at strengthening stability, its shorthand for actions designed to support the exchange rate and anchor inflation expectations. The central bank has repeatedly indicated that maintaining rupiah stability is a pre-condition for delivering its inflation objective.

Indonesia has been navigating a period of shifting global rate expectations and heightened volatility in emerging market currencies, factors that have complicated the setting of domestic monetary policy across the region. The tightening pushes Indonesia's benchmark further above levels prevailing at the start of the year, when policy had been calibrated to a different external environment.

The Board of Governors did not commit to a specific path for subsequent meetings in its communication, keeping open the option to move again if conditions warrant. The next scheduled policy decision will be closely watched for guidance on whether Wednesday's 50 basis point move marks the start of a sustained tightening phase or a one-off adjustment to reinforce policy credibility.

Domestic banks will now be recalibrating their lending and deposit pricing to reflect the higher corridor, while the transmission of the move to short-term interbank rates will depend on liquidity conditions in the coming weeks. Bank Indonesia said it would continue to deploy its full mix of instruments, including SRBI issuance, to support the transmission of the policy stance. The updated corridor, with the Deposit Facility at 4.25 per cent and the Lending Facility at 6.00 per cent, keeps the standard 100 basis point width around the BI-Rate that the central bank has used to bound overnight money market rates.
