New Central Bank Rules Boost Banking Flexibility and Rupiah Stability

JAKARTA, Investortrust.id — Bank Indonesia is loosening the reins on the national banking sector, signaling a strategic shift to bolster credit growth. Governor Perry Warjiyo announced on Thursday that the maximum Bank Foreign Funding Ratio (RPLN) will rise from 35% to 40% starting July 1, 2026.

For global investors and local stakeholders, this policy pivot provides a critical safety valve for Indonesian banks. By expanding access to international capital markets, the central bank is reducing the domestic sector's reliance on local deposits, theoretically lowering the cost of credit and fueling growth in key strategic sectors. This, combined with an interest rate hike to 5.75%, demonstrates a central bank balancing aggressive growth targets with the need for currency stability.

Banking Giants Respond

Bank Central Asia (BBCA), the nation’s largest private lender by market capitalization, was quick to praise the regulatory easing. The move provides the industry with a valuable buffer, ensuring that banks have the liquidity needed to meet future loan demand.

Hera F. Haryn, EVP of Corporate Communications and Social Responsibility at BCA, told Investortrust.id on Monday that the firm appreciates the increased flexibility. She noted that while the option to tap foreign markets is now broader, BCA remains comfortably positioned, with its primary focus firmly rooted in the domestic market to match its massive portfolio of rupiah-denominated loans.

Liquidity Remains Robust

Despite the regulatory shift, there is little urgency for major players to rush toward foreign funding. BCA’s own balance sheet confirms this, as the bank reported a stellar 11.2% year-on-year growth in current and savings accounts (CASA) during the first quarter of 2026.

This surge brought the bank's core low-cost deposits to Rp 1.089 quadrillion ($68.5 billion). These cheap deposits now make up roughly 85.2% of BCA’s total third-party funds, cementing the bank's status as a liquidity powerhouse that remains largely insulated from global funding volatility.

Strengthening the Rupiah

Bank Indonesia is coupling this regulatory flexibility with a firmer monetary stance to defend the Rupiah. With the conflict in the Strait of Hormuz de-escalating, Governor Warjiyo expressed high optimism that the local currency will return to its fundamental strength.

The 25-basis-point hike to the BI Rate, bringing it to 5.75%, is a clear signal of the central bank's pre-emptive approach to anchor inflation within its 2.5% target range. As the bank introduces more transparency through public assessment of loan interest rates, it aims to ensure that these policy stimuli directly benefit the real economy rather than getting stuck in banking balance sheets.
