Indonesia’s March CPI slowed to 3.5% year-on-year, moving back into Bank Indonesia’s target range. Inflation is expected to keep easing over the next few months.
There are still upward risks to inflation linked to a prolonged Middle East conflict. Potential channels include higher freight costs, supply chain disruption, and precautionary stockpiling, while fuel subsidies remain in place.
Bank Indonesia is expected to keep the policy rate unchanged at 4.75% at its 22 April meeting. At its March meeting, the central bank removed its easing bias.
The policy shift followed higher rupiah volatility and weaker sentiment. USD/IDR rose above 17,000 last week.

We are seeing a familiar pattern where Indonesian inflation is moderating, but Bank Indonesia’s hands are tied. When we look back at the situation in March of 2025, CPI had also slowed to 3.5%, yet the central bank removed its easing bias then. The primary concern remains the weak Rupiah, forcing a hawkish stance even with softer price pressures.
This caution from 2025 was justified, as the Rupiah’s weakness has persisted throughout the last year. The USD/IDR exchange rate, which crossed 17,000 back then, is now hovering closer to 17,350. Consequently, Bank Indonesia has not only held rates but was even forced into a hike, with the policy rate now standing at 5.00%.
For traders, this creates a clear signal for playing currency volatility through options. Given BI’s focus on currency stability over inflation targeting, any external shock could trigger sharp moves in the IDR. This suggests that long volatility strategies, such as buying straddles on USD/IDR, could be beneficial in the coming weeks.
The interest rate derivatives market may be underpricing the central bank’s hawkish resolve. Despite recent inflation data for March 2026 coming in at a manageable 3.8%, rate cut expectations should be muted. Traders could look at paying fixed on short-term interest rate swaps, betting that BI will hold rates higher for longer than the market currently anticipates.
We must also consider the upside inflation risks that were highlighted back in 2025. With geopolitical tensions remaining and WTI crude oil prices firming around $95 a barrel, the threat of higher import costs is real. This reinforces the view that Bank Indonesia has very little room to consider easing its policy anytime soon.
