Bank Mandiri (BMRI), one of Indonesia’s banking giants, reported a net profit of IDR 13.3 trillion for the third quarter of 2025 (3Q25), marking an 18% quarter-on-quarter increase but a 14% year-on-year decline. This performance brings its 9M25 net profit to IDR 37.7 trillion, a 10% decrease year-on-year, yet aligning with consensus expectations by reaching 75% of the 2025 full-year estimate. While the sequential growth signals resilience, a deeper dive reveals significant shifts in operational dynamics and strategic adjustments underway.

Unpacking 3Q25 and 9M25 Performance: A Tale of Two Trends

The bank’s 3Q25 results broadly mirrored the trends observed over the nine-month period, with the annual decline in net profit primarily attributable to two key factors.

Pre-Provision Operating Profit Under Pressure Amidst Rising Costs

A significant contributor to the year-on-year profit dip was a weaker Pre-Provision Operating Profit (PPOP). This metric faced headwinds from a notable surge in operating expenses (opex), which outpaced the modest low-single-digit growth in Net Interest Income (NII). The operational leverage, a critical indicator for banks, clearly felt the squeeze.

Rising Provisions Temper Bottom Line

Concurrently, an uptick in provision expenses further constrained net profit. Provisions jumped 22% year-on-year in 3Q25, culminating in a 10% year-on-year increase for the 9M25 period. This proactive provisioning, while impacting short-term profitability, often reflects prudent risk management in a dynamic economic landscape.

Operational Dynamics: Navigating the Opex Surge and NII Nuances

Bank Mandiri’s management had previously guided on the elevated opex, and 3Q25 reaffirmed this trajectory.

Opex Soars, PPOP Recedes

Operating expenses escalated by a substantial 25% year-on-year in 3Q25, pushing PPOP down by 9% year-on-year for the quarter and 7% year-on-year for 9M25. Management maintains its 2025 guidance for opex growth to hover around 25%, with an expectation for normalization to a flat year-on-year trajectory in 2026. This significant expenditure likely underpins strategic investments in technology or branch network optimization, crucial for long-term competitiveness.

NII Growth Stymied by Cost of Fund Pressures

Net Interest Income, the lifeblood of banking, saw only modest growth of 1% year-on-year in 3Q25 and 5% year-on-year for 9M25. This subdued expansion was largely due to lingering pressure on the Cost of Fund (CoF). Encouragingly, a decline in CoF, spurred by government liquidity injections, began to materialize in September 2025, with the month-to-date CoF dropping to 2.33% (compared to 2.46% in 1H25 and 2.43% for 9M25). This trend promises a more favorable NII environment moving forward.

Non-Interest Income Provides Stability

Amidst these fluctuations, Non-Interest Income (Non-II), which includes net insurance income, remained a stable pillar of strength. It recorded solid growth of 8% year-on-year in 3Q25 and 5% year-on-year for 9M25, reflecting the bank’s diversified revenue streams and robust fee-based activities.

Asset Quality: A Fortress Maintained, Provisions Ahead of Schedule

Despite the broader economic environment, Bank Mandiri continues to exhibit disciplined asset quality management.

NPL and LAR Trends Signal Prudence

Both Non-Performing Loans (NPL) and Loan-at-Risk (LAR) showed improvement by September 2025 (compared to June 2025), settling at 1.19% and 6.48% respectively. These reduced ratios underscore the bank’s effective risk mitigation strategies and the underlying health of its loan portfolio.

Cost of Credit Underscores Prudent Management

While provision expenses rose in 3Q25, the Cost of Credit (CoC) for 9M25 stood at an impressive 0.7%, remaining well below the 2025 guidance of 0.8-1%. With expectations for stable asset quality into 4Q25, there is a strong possibility that the full-year CoC will finish even lower than initial projections, signaling superior credit risk management.

Gazing into 2026: Higher Loan Growth, NIM on a Tightrope

While official 2026 guidance is pending, Bank Mandiri’s management has offered insightful indications for the year ahead.

Anticipating Accelerated Loan Growth

The bank foresees potentially higher loan growth in 2026, surpassing its 2025 guidance of 8-10% year-on-year. This optimism is fueled by anticipated macroeconomic improvements, particularly driven by increased government spending and a general trend of declining interest rates. Such an environment creates fertile ground for credit expansion across various sectors.

The NIM Challenge: Maintaining Margins in a Shifting Landscape

The primary challenge for 2026, according to management, lies in managing Net Interest Margin (NIM). With easing liquidity, competitive pressures are expected to intensify, potentially putting downward pressure on loan yields. Bank Mandiri aims to maintain NIM at a relatively stable level by strategically managing its Cost of Fund, leveraging the anticipated decline in borrowing costs to offset yield compression. This proactive approach underscores a shrewd balancing act between growth and profitability.

Bank Mandiri’s 3Q25 performance reveals a bank actively adapting to evolving market conditions. While navigating temporary profit headwinds from elevated operational costs and increased provisions, the underlying asset quality remains robust, and strategic efforts to optimize funding costs are gaining traction. With an eye on accelerated loan growth and a determined strategy to protect margins in a lower interest rate environment, BMRI is positioning itself for sustained strength and leadership in the Indonesian banking sector into 2026.
