Jakarta Stocks Post 7.5% Rebound as Surprise Rate Hike and State Buyback Prop Up Markets

JAKARTA, Investortrust.id — Indonesian equities staged a spectacular, history-making comeback on Tuesday, as the Jakarta Composite Index (JCI) rocketed 7.57% to close at 5,746.648.

The record-breaking single-day blast erased a punishing 4.52% capitulation from the previous session, comfortably outperforming every major equity market across Asia. This massive turnaround caught global macro funds completely off guard, fueled by an aggressive, dual-pronged defense strategy consisting of an emergency interest rate hike by Bank Indonesia and an unprecedented, state-coordinated equity buyback mandate.

For global emerging market asset managers, Tuesday's extraordinary price action reveals the lengths to which Jakarta will go to defend its financial architecture from aggressive capital flight. Faced with escalating Middle East conflict anxieties and a bleeding Rupiah, Indonesian technocrats responded with raw financial force. By combining classic monetary tightening with state-directed market stabilization, the government has established a firm floor underneath domestic valuations, structurally shifting the risk-reward calculus for regional carry-trade strategies.

Central Bank Triggers Shock Rate Hike

The absolute core catalyst behind the mid-day reversal came directly from the central bank's trading desk. Bank Indonesia (BI) Governor Perry Warjiyo delivered a surprise 25-basis-point interest rate hike, raising the benchmark BI-Rate to 5.50% during a specialized legislative hearing.

"We do not like raising interest rates, but to attract foreign portfolio investments that are currently staying abroad, interest rates must go up everywhere," Governor Warjiyo explained to lawmakers in the House of Representatives (DPR) Budget Committee room in Jakarta on Tuesday afternoon. Warjiyo admitted that the emergency policy pivot was a direct response to a rapid domestic currency depreciation that had severely overshot the bank's internal safety models.

To sweeten the deal for international investors, BI slashed hedging swap costs by 10% and ramped up its flagship Bank Indonesia Rupiah Securities (SRBI) liquidity drain auctions. Warjiyo reassured international capital desks that the nation’s war chest remains impenetrable, noting that foreign exchange reserves stand well above 115% of the International Monetary Fund's (IMF) adequacy standard, equivalent to over six months of baseline imports.

Parliament Activates State Institutional Buyback

Simultaneously, the political establishment moved to squeeze short-sellers out of the market entirely. House of Representatives Deputy Speaker Sufmi Dasco Ahmad held a closed-door emergency council meeting with the chief executives of the State-Owned Banks Association (Himbara), the State-Owned Enterprises Management Agency, and the Ministry of State Secretariat to orchestrate an aggressive structural market intervention.

"We discussed how, at the right opportunity in my opinion, we buy back or purchase back shares in the stock market," Deputy Speaker Dasco told reporters at the Parliament Complex in Jakarta on Tuesday morning. Dasco revealed that the state will likely mobilize capital from the country's multi-billion dollar state-backed investment houses, including Danantara, the state workers' pension fund (BPJS Ketenagakerjaan), and civil service fund manager Taspen, to absorb undervalued public shares.

Himbara Chairman Putrama Wahju Setyawan immediately backed the intervention, reminding global investors that the underlying fundamentals of state lenders remain exceptionally healthy. Setyawan pointed out that loan growth is tracking at 20%, deposit expansion is hovering near 30%, and average non-performing loans (NPLs) are sitting safely below the 2% threshold.

Blue Chips and Barons Fuel the Rally

The combined policy bazooka triggered an absolute buying frenzy across the exchange floor, with gainers outpacing decliners by a massive 971 to 182. Heavily weighted blue-chip state banks completely reversed their recent tumbles, with PT Bank Rakyat Indonesia (BBRI) and PT Bank Negara Indonesia (BBNI) both roaring over 5% higher, while telecom monopoly PT Telkom Indonesia (TLKM) surged 9.79%.

The momentum spilled heavily into cyclical and industrial sectors, with the basic materials index surging 8.22% while energy and industrial indexes both advanced over 7%. The rally was supercharged by a massive wave of capital flowing back into mega-cap green energy and petrochemical firms controlled by billionaire industrialist Prajogo Pangestu, including PT Chandra Asri Pacific (TPIA), PT Barito Pacific (BRPT), and PT Barito Renewables Energy (BREN).
