NextFin News - Bank Indonesia raised its benchmark BI-Rate by 25 basis points to 5.5% on Tuesday, an off-cycle move meant to defend a rupiah that had fallen through 18,000 to the dollar and to calm a market selloff that has spread from currency trading into bonds and stocks. The central bank said the step was meant to stabilise the exchange rate and keep inflation within target in 2026 and 2027. It worked, at least for a day: the rupiah gained as much as 0.8% against the dollar, its biggest rise in nine months.
The harder problem is that rates alone cannot answer what is unsettling investors. Reuters said the currency has been under pressure from President Prabowo Subianto’s spending plans, a swelling fuel subsidy bill after the Iran war, doubts over Bank Indonesia’s autonomy and a string of controversial commodity export policies. That is why the market reaction has been so blunt. Higher yields can slow the outflow of capital, but they do not by themselves change the policy mix that drove investors to sell in the first place.
That view comes from analysts who have been openly cautious on Indonesia’s currency. Wee Khoon Chong of BNY said, in comments quoted by Bloomberg, that the off-cycle increase was “the clearest signal” of Bank Indonesia’s resolve, but that the total 75 basis points of tightening so far may still not be enough to halt depreciation pressure. Jeffrey Zhang of Credit Agricole CIB was even plainer: policy hikes will not reverse rupiah weakness, although they may curb excess volatility. Both are long-time emerging-markets currency watchers whose calls tend to lean defensive when policy credibility is in question. Their argument is not a consensus verdict; it is a warning from analysts who spend their time looking for stress, not comfort.
The central bank is already paying a price for that defence. Reuters reported that Indonesia’s foreign-exchange reserves fell by $1.3 billion in May to $144.9 billion, their lowest in nearly two years, even after the government sold $3.5 billion of dollar- and euro-denominated bonds last month. That matters because reserves are the first line of defence when a currency comes under pressure. If they keep shrinking, the authorities have fewer tools to smooth volatility without doing more damage to confidence.
Prabowo also faces a policy trade-off that is easy to describe and hard to escape. Higher rates can support the rupiah and may pull in foreign portfolio money by making local bonds more attractive, but they also raise borrowing costs for companies and households at a time when growth depends on domestic demand. Bloomberg quoted analysts saying the latest hike may support Indonesian stocks over the longer run, yet the near-term effect on returns is likely to be a drag. That is not a contradiction. It is the cost of trying to defend a currency while investors are still pricing in a broader shift in the state’s role in the economy.
The next test comes quickly. BNY sees room for another hike at the June 18 meeting if the rupiah does not stabilise. Bloomberg also cited Credit Agricole’s view that any additional move in the second half would depend on fresh shocks, including energy prices, the MSCI equity review and the sovereign rating review. That leaves Prabowo with a narrower task than simply forcing the central bank to tighten again. He needs to show that fiscal policy, export rules and central-bank independence will not keep working against each other. The market has already voted on the question once.
