OCBC’s first-quarter results tested whether wealth, deposits, and client activity can continue to absorb lower-rate pressure. Net profit rose to SGD 1.97 billion ($1.46 billion) on record total income of SGD 3.83 billion ($2.83 billion). This result came despite a 5% year-on-year fall in net interest income (NII) to SGD 2.22 billion ($1.64 billion), as the net interest margin (NIM) narrowed to 1.76%, 28 basis points below a year earlier.

Wealth, fees, and balance sheet deployment supported the earnings defence. Non-interest income reached a quarterly high of SGD 1.61 billion ($1.19 billion), more than absorbing the NII decline and allowing OCBC to grow profit in a lower-rate environment. Wealth management income rose 11% year-on-year to SGD 1.48 billion ($1.10 billion), while fee income increased 24% to SGD 675 million ($499 million). Customer deposits rose 10% year-on-year to SGD 444 billion ($329 billion), while OCBC’s deployment of surplus liquidity and wholesale funding into high-quality treasury assets mitigated roughly 30% of the rate impact on loans.

The HSBC international wealth and premier banking (IWP) portfolio in Indonesia gives OCBC more wealth clients and deposits without adding a large loan book. The bank also set aside SGD 191 million ($141 million) in allowances for non-impaired assets and raised the non-performing asset (NPA) coverage ratio to 163%.

Tan Teck Long, group chief executive officer of OCBC, said the quarter showed broad-based growth across loans, deposits, and non-interest income. “All this was achieved in the context of a low interest rate environment,” he added. OCBC did not avoid rate pressure, but showed that wealth, client flows, and deposits can carry more of the earnings burden when lending spreads weaken.

Wealth is carrying more of the earnings burden

The quarter showed wealth contributing directly to earnings resilience, not just long-term strategy. Wealth income drew support from affluent and private banking activity, providing the group with several sources of revenue when lending spreads came under pressure. Goh Chin Yee, group chief financial officer of OCBC, said record non-interest income, led by wealth management, “more than compensated” for the decline in NII. The strength in fees came from higher customer investment activity across its wealth franchise.

Customer-flow treasury income also gave OCBC another client-led source of non-interest income. Tan distinguished this from trading for the bank’s own account, stating that OCBC’s priority is to grow customer flows through treasury products. OCBC has also added product and sales resources to support customer-flow growth across both wealth and corporate relationships. As a result, income is tied to recurring wealth and corporate banking activity, rather than mainly to market positioning.

Balance sheet deployment limits the rate drag

OCBC’s earnings defence did not rely on wealth alone. The bank also used its balance sheet to limit the NII decline by deploying surplus liquidity from deposit growth and a pre-emptive increase in wholesale funding into high-quality treasury assets. This choice diluted margin but gave the bank another source of income as loan yields compressed.

Goh described this approach as “protecting NII” and noted that the bank intends to keep building the treasury asset buffer, though at a slower pace. On a day-adjusted basis, NII was only 1% lower quarter-on-quarter, showing how funding management and treasury deployment softened the rate drag. OCBC is using liquidity and capital to generate income across rate cycles, rather than relying mainly on loan spreads.

Indonesia acquisition adds deposits and wealth scale

The acquisition of HSBC’s IWP portfolio in Indonesia matters because it gives OCBC more wealth clients, more deposits, and only a small loan book. Tan argued that the portfolio aligned with OCBC’s strategy because it added wealth relationships, deposits, and scale in Indonesia without bringing a large credit exposure. The portfolio comprises SGD 6.6 billion ($4.9 billion) in assets under management (AUM), including SGD 4.3 billion ($3.2 billion) in customer investments and SGD 2.3 billion ($1.7 billion) in customer deposits, against a retail loan book of SGD 300 million ($222 million). For a bank, those deposits are not merely liabilities; they are low-cost funding that can support lending and other earning assets.

Tan argued that the deposit-heavy structure gives OCBC a funding advantage, while the small loan book limits credit risk. OCBC’s existing scale in Indonesia anchors the rationale, while Bank of Singapore’s product capabilities are expected to support the enlarged Indonesian wealth franchise. The deal also tests whether OCBC can use local deposits, wealth clients, and Bank of Singapore’s product capabilities to build fee and funding income across ASEAN.

Risk buffers support the income shift

OCBC’s broader income base still depends on a stable loan book. The bank set aside additional allowances for non-impaired assets as a buffer against macroeconomic risks from the Middle East conflict, particularly the potential impact on energy prices across Southeast Asia. Management did not present this as evidence of stress in the portfolio but as a precautionary measure.

Tan said OCBC did not see credit-quality issues in the portfolio, but took general provisions for non-impaired loans as a prudent response to broader macro risk. The underlying credit position remained sound. This matters because wealth income, deposit growth, and treasury deployment can only support earnings if the loan book remains resilient through a more volatile external environment.

Guidance focuses on execution

OCBC’s decision to maintain its full-year guidance raises the bar for execution following a strong first quarter. The bank guided for total income to remain stable to growing, a slight to moderate decline in NII, and credit costs of 20 to 25 basis points. As the rate cycle becomes less supportive, the critical question for regional banks will be not how much margin they can extract from the balance sheet, but how effectively they can convert client relationships into fee income, treasury flows, low-cost funding, and advisory engagement.

For OCBC, scale alone will not be enough. The bank must show that wealth growth can continue beyond favourable market activity, that customer-flow treasury income remains anchored in client demand rather than market volatility, and that the Indonesia acquisition can add deposits and AUM without importing significant credit risk. The integration of the IWP acquisition will demonstrate whether OCBC can turn deposits and client activity into recurring income across its regional franchise, not just a temporary defence against lower rates.
