BI's Surprise Rate Hike: Are Bank Stocks Still a Safe Investment?
Bank Indonesia’s aggressive move to raise the benchmark interest rate is expected to redraw the competitive landscape and profitability within the domestic financial industry. According to a recent analysis report by BNI Sekuritas, the central bank’s decision to increase the BI-Rate by 25 basis points to 5.50 percent during a Weekly Board of Governors Meeting on Tuesday, 9 June 2026, marks a new precedent. This tightening action signifies the first implementation of an off-cycle interest rate policy since May 2018. The emergency policy follows a 50 bps rate hike at the monthly board meeting last May. Such aggressiveness underscores BI’s strong commitment to monetary stability, aimed at defending the rupiah exchange rate from a steep decline while maintaining the attractiveness of domestic financial assets amidst global market volatility.
Simultaneously, the central bank is intensifying the issuance of Bank Indonesia Rupiah Securities instruments. Market data indicates the latest weighted average yield rate for SRBI has touched 7.2 percent, the highest level since January 2025. Consequently, the ratio of outstanding SRBI has climbed to encompass 10.3 percent of the total national banking deposit system. The spike in the BI-Rate coupled with the high absorption of funds via SRBI instruments will generally pose a significant challenge for the domestic banking industry. This scenario is projected to trigger liquidity tightening in the money market and drive up the cost of funds borne by banks.
Nevertheless, within the competitive map of the Big-4 market-controlling banks, PT Bank Central Asia Tbk is deemed to possess the most superior resilience in facing this era of high interest rates. BBCA’s comparative advantage is supported by several structural factors, including a jumbo portfolio exposure where its SRBI holdings account for 22 percent of total non-loan earning assets and a positive Net Interest Margin sensitivity. Unlike competitors whose margins are threatened by funding costs, BBCA benefits from a strong Current Account Savings Account structure. Simulation analysis shows that every 75 bps increase in the benchmark rate could potentially boost BBCA’s NIM by approximately 15 bps. Therefore, analysts have placed BBCA as the top pick due to its strategic positioning in a high interest rate climate, proven earnings resilience, a track record of clean asset quality, and a relatively attractive stock valuation compared to its fundamentals.
Observing the massive sell-off that has hit the financial sector recently, BNI Sekuritas assesses that the downgrade of major bank stocks has been purely triggered by macroeconomic panic and global sentiment, not by a deterioration in the fundamental performance of banking issuers. The current discounted share price condition places Indonesian banking valuations at very cheap levels. The current market price reflects a Return on Equity for Big-4 issuers ranging only from 12 to 17 percent, far below the real growth estimates compiled by analysts for the FY2026F–2027F period. Furthermore, the market consensus has so far only revised down the 2026 fiscal year earnings estimate by approximately 1 percent year-to-date, signaling that the net profit indicators of banking issuers remain very stable.
On the fiscal policy front, the market also responded positively to coordination between monetary authorities and the executive branch. Beyond the interest rate tightening intervention by BI, the government has proven responsive by rationalising state budget spending, including a decision to cut the budget ceiling allocation for the Free Nutritious Meal Programme for the 2026 fiscal year to maintain the resilience of the fiscal deficit. Given that the valuation of national banking stocks is currently approaching its cycle bottom, supported by maintained levels of profitability and non-performing loan asset quality, along with increasingly attractive dividend yield potential post-price correction, BNI Sekuritas has taken an optimistic step. The securities firm has officially upgraded the investment rating for the Indonesian banking sector in the short term, over the next 3 months, to Overweight, while maintaining a positive Overweight outlook for the long term over 12 months.
