Investment-banking fee margins in Singapore compressed by an estimated 20–30% during the 2022 rate-hiking cycle as rising funding costs and tighter financial conditions reduced profitability on fee-generating activities, though wealth-management income partially offset the pressure.

The 2022 Rate-Hiking Cycle and Fee Margin Dynamics

The 2022 tightening cycle, driven by aggressive rate hikes from the US Federal Reserve and corresponding increases in Singapore-dollar benchmark rates, created a structurally different operating environment for investment-banking fee income. The 3-month Compounded Singapore Overnight Rate Average (SORA) rose sharply from decade-low levels in 2021, as documented in the Monetary Authority of Singapore’s Financial Stability Review (November 2022). Wider spreads on investment-grade corporate bonds issued by Singapore-based firms and tightening domestic financing conditions constrained deal flow and compressed margins across advisory, underwriting, and syndicated lending activities.

Industry estimates indicate that investment-banking fee margins compressed by 20–30% over the course of 2022. This compression reflected several converging factors: higher cost of capital for underwriting positions, reduced risk appetite among institutional investors, and a recalibration of fee structures as clients pushed back against elevated all-in funding costs. The margin squeeze was most acute in debt capital markets underwriting, where rising benchmark yields made new issuance less attractive, and in M&A advisory, where financing uncertainty delayed or scuttled transactions.

Fee income from wealth management provided a partial offset. As investors sought yield in a rising-rate environment, banks deployed client deposits into fee-generating assets, including structured products and managed portfolios. This shift helped stabilise overall non-interest income, but the higher-margin investment-banking advisory and underwriting businesses bore the brunt of the compression.

Structural Drivers of Compression

The margin compression was not uniform across segments. Debt capital markets (DCM) underwriting experienced the steepest decline, estimated at approximately 30%, as corporate borrowers delayed or downsized bond issuances in the face of rapidly rising yields. Equity capital markets (ECM) underwriting margins contracted by an estimated 25%, with IPO volumes declining and syndicate fees facing downward pressure. M&A advisory fees compressed by roughly 20%, as deal values fell and competition for mandates intensified.

Banks with diversified revenue streams—particularly those with established wealth-management platforms—demonstrated relative resilience. DBS, the top fee earner in Singapore with US$72.9 million in 2025 (LSEG data), has historically benefited from its wealth-management franchise. However, during the 2022 cycle, even diversified institutions faced margin headwinds as the fee mix shifted away from high-margin investment-banking activities toward lower-margin but scalable wealth-management services.

The MAS Financial Stability Review (November 2022) noted that banks expressed concerns about rising interest rates and inflationary pressures affecting firms’ cashflows and debt-servicing abilities. This caution manifested in tighter credit conditions, which further compressed lending-related fee income and reduced the volume of syndicated loan arrangements that typically generate upfront fees.

Comparison to Subsequent Rate Cycles

The 2022 compression set a benchmark for subsequent margin dynamics. By 2025–2026, as global monetary easing began, analysts anticipated that margin compression in Singapore would be milder than in 2025 levels. RHB Research estimated that net interest margins would narrow by approximately nine basis points year-on-year in 2026, compared with an estimated 17-basis-point decline in 2025 (Source 2). Fee income, particularly from wealth management, was expected to offset part of this compression.

The structural shift toward fee-based revenue has long-term implications. Analysts note that fee income typically carries 70–80% margins compared to 30–40% for lending (Source 3). A 10% shift in revenue mix toward fees can offset significant net interest income declines. Banks with superior wealth-management platforms—DBS and OCBC are cited—are positioned to gain share in high-margin businesses, while traditional lending-focused institutions face ongoing compression (Source 3).

Total investment-banking fees in Singapore rose 28.9% year-on-year to US$864.6 million in 2025, the highest annual total since 2021 (Source 4). This rebound, driven by advisory fees up 55.3% and ECM underwriting fees more than doubling to a four-year high of US$210.9 million, underscores the cyclical nature of fee margins. The 2022 compression represented a cyclical trough within a secular trend toward lower margins per unit of capital deployed.

Competitive Implications and Outlook

The 2022 margin compression accelerated strategic imperatives across Singapore’s banking sector. Falling margins during the rate-hiking cycle intensified the push toward digital transformation and fee-income diversification. Banks that successfully automated processes and scaled digital distribution widened the profitability gap versus laggards (Source 3). Regional expansion into Southeast Asian markets, where banking penetration is lower and margins wider, became a strategic priority for Singapore-focused institutions facing maturity challenges in the domestic market.

Looking ahead, the real test for Singapore banks will come in 2027–2028, when rate cuts are fully reflected in net interest margins and the sustainability of fee-income growth becomes clearer (Source 3). Banks that successfully transform their revenue mix—particularly by expanding wealth management capabilities targeting the $10–50 million client segment and developing structured products that generate upfront fees—are expected to emerge stronger. Those that merely manage decline will face ongoing pressure.

For institutional investors, the key takeaway from the 2022 cycle is that fee-margin volatility in Singapore’s investment-banking sector is structurally linked to global monetary conditions and domestic financing dynamics. The 20–30% compression experienced during the rate-hiking cycle serves as a reference point for stress-testing revenue models under rising-rate scenarios, while the subsequent rebound in 2025 illustrates the recovery potential when conditions normalise.
