Indonesian Banking Stocks Surge as Rate Hike and Buyback Blitz Trigger Dramatic Equity Rebound

JAKARTA, Investortrust.id — A powerful mix of aggressive monetary tightening and political intervention has triggered a massive relief rally in Southeast Asia's largest banking sector. The Jakarta Composite Index (JCI), the benchmark of the Indonesia Stock Exchange (IDX), exploded by 7.57% or 404 points to close at 5,722, erasing weeks of capital outflow anxiety in a single day.

The blockbuster equity rebound accelerated on Wednesday morning, June 10, 2026, with the index jumping an additional 1.55% to 5,838 within the first ten minutes of trading. The spectacular turnaround came as Bank Indonesia (BI), the country's central bank, unexpectedly hiked the benchmark BI Rate by 25 basis points to 5.50% to aggressively defend the domestic currency.

Indonesia’s mega-banks are screaming value. Market sentiment and psychological fears had severely decoupled from stellar corporate earnings, driving valuations to unjustifiably cheap levels. With the central bank decisively stabilizing the macro picture and lawmakers backing institutional stock buybacks, this sudden price surge signals the start of a major valuation correction for some of the most profitable banking institutions in Asia.

The Great Banking Rebound

The financial sector led the charge, spearheaded by the country’s dominant Tier-4 (KBMI IV) banking giants and state-owned lenders. PT Bank Mandiri Tbk (BMRI), the country's largest lender by assets, skyrocketed 10.24% to Rp 4,090 ($0.26), while state-backed micro-finance powerhouse PT Bank Rakyat Indonesia Tbk (BBRI) surged 7.72% to Rp 2,790 ($0.18). Private-sector heavyweight PT Bank Central Asia Tbk (BBCA) climbed 6.19% to Rp 5,150 ($0.32), and Islamic mega-lender PT Bank Syariah Indonesia Tbk (BRIS) surged a spectacular 13.93% to Rp 1,840 ($0.12).

The explosive buying interest ignited after House of Representatives (DPR) Deputy Speaker Sufmi Dasco Ahmad publicly urged the newly formed super-holding agency Danantara and state-backed lenders to immediately initiate stock buybacks. Lawmakers argued that bank stock prices had plummeted into deep oversold territory that completely failed to reflect their pristine fundamental value.

Prominent domestic brokerages are telling clients to load up on these assets before the entry window slams shut. BRI Danareksa Sekuritas maintained its conviction "Buy" ratings across the board, setting an ambitious target price of Rp 10,900 for BBCA—implying a massive 111% upside from current trading levels. The firm also slapped "Buy" targets on BBNI at Rp 4,700, BMRI at Rp 6,200, and BRIS at Rp 3,100. Meanwhile, MNC Sekuritas is targeting Rp 4,050 for BBRI, noting that the current fire-sale prices represent an incredibly cheap forward price-to-book value (PBV) of just 1.8 to 1.9 times for the 2026-2027 fiscal period.

Dividends Form the Ultimate Defensive Shield

Wall Street and regional analysts note that macro anxieties had overextended the market's recent downturn. In an investment note released on Wednesday, Mandiri Sekuritas, the investment banking arm of state-owned Bank Mandiri, pointed out that temporary market hysteria had overshadowed pristine balance sheets.

"With market conditions still clouded by negative sentiment, dividends are a critical anchor helping to maintain investor confidence in equities with rock-solid fundamentals," Mandiri Sekuritas wrote in its latest strategy report published Wednesday, June 10, 2026.

The brokerage emphasized that visible, highly sustainable dividend payouts from these banking giants will act as the ultimate defense mechanism for institutional portfolios. These yields are expected to draw in long-term domestic capital, shielding the market even as global competition for capital risks sparking broader emerging market outflows.

Rupiah Breaks Below the Psychological Danger Zone

The equity market's aggressive resurgence was perfectly complemented by a dramatic recovery in the currency market. The Indonesian rupiah staged a powerful counter-offensive against a retreating US Dollar Index (DXY), strengthening 0.55% to trade at Rp 17,958 per dollar, successfully busting below the highly sensitive Rp 18,000 psychological floor.

Andry Asmoro, Chief Economist at PT Bank Mandiri Tbk, noted that a sudden cooling of geopolitical hostilities between Israel and Iran prompted international investors to unwind safe-haven dollar positions, providing immense breathing room for Asian currencies.

However, Asmoro warned that global macro pressures remain elevated, keeping the greenback near multi-month highs due to resilient US labor data that could prompt the Federal Reserve to hike rates in December. To counter this, Bank Indonesia paired its rate hike with aggressive new incentives to lure back foreign portfolio flows. This swift policy package has effectively re-established institutional trust in Jakarta's financial system, laying a sturdy foundation for the country's dirt-cheap equity markets to continue their upward march.
