Safe-haven inflows, particularly from Middle East clients, drive deposit growth as SGD deposits outperform foreign currency.

Record Deposit Levels and Growth Trends

Singapore's total bank deposits reached an all-time high of USD 1,628.641 billion in March 2026, marking an 11.8% year-on-year increase, according to CEIC data. This record level—the highest since CEIC began tracking monthly data in January 1991—represents a significant acceleration from the previous month's USD 1,608.487 billion. For context, the all-time low of USD 99.345 billion was recorded in June 1991, and the monthly average over the full 35-year series stands at USD 515.664 billion. The current figure is more than three times that average, reflecting decades of sustained deposit accumulation in Singapore's banking system. Month-on-month growth of approximately 1.3% from February to March 2026 indicates continued upward momentum entering the second quarter.

Safe-Haven Inflows Amid Geopolitical Risks

The record deposit base is being driven primarily by safe-haven capital flows, particularly from clients in the Middle East region seeking stability amid ongoing conflict. DBS Group Holdings stated in a March 2026 bourse filing ahead of its annual general meeting that "the ongoing conflict in the Middle East has supported deposit growth through safe-haven inflows," as reported by The Business Times. The bank further noted that market volatility from the conflict could also lift trading income, though it flagged attendant risks.

UOB Kay Hian analyst Jonathan Koh reinforced this assessment, telling Asian Banking and Finance that "heightened geopolitical uncertainties have reinforced Singapore's safe-haven appeal, driving deposit growth and wealth management inflows into local banks, particularly from Middle East-based clients reallocating assets away from perceived riskier jurisdictions in the Gulf region, such as Dubai." Koh specifically cited Dubai as a jurisdiction from which capital is being reallocated.

Data from FOZL Group, citing MAS statistics, confirms that Singapore dollar (SGD) deposits are significantly outperforming foreign-currency deposits. As of end-2025, total SGD deposits held with local banks grew 8.9% year-on-year, compared to approximately 3.6% for foreign-currency deposits. From November 2024 onward, SGD deposits maintained particularly strong momentum, with year-on-year growth exceeding 10% in certain months. Analysts at FOZL Group note that "as major global economies enter an interest rate easing cycle, narrowing interest rate differentials—combined with heightened geopolitical risks—have prompted some capital to shift away from higher-volatility assets toward more stable markets."

The scale of foreign exposure to Singapore's banking system is substantial. The International Monetary Fund, in its 2025 Country Report (No. 25/193), estimated that liabilities of the Singaporean banking system to non-residents totaled 194.4% of GDP as of December 2024, accounting for 36.8% of total banking sector liabilities. Within this, non-bank deposits by non-residents reached 86.7% of GDP. These figures underscore Singapore's deep integration with global capital flows and its role as a repository for international wealth.

Role of Major Banks and Financial Stability

The three domestic systemically important banks (D-SIBs)—DBS, UOB, and OCBC—form the backbone of Singapore's financial sector, accounting for approximately 52% of the nation's banking sector assets as of December 2024, per the IMF. These institutions are benefiting directly from the deposit inflows. SGX data cited by Asian Banking and Finance shows that the combined non-interest income of the three banks reached USD 5.16 billion in the first quarter of 2026, driven by wealth management, trading, and fee income. Wealth management flows were a key contributor across all three banks, reflecting sustained investor demand for diversified and defensive asset allocation. Combined net interest income has remained above USD 8 billion for the 14th consecutive quarter, highlighting underlying stability despite regional interest rate headwinds.

DBS has stated that it maintains "robust" frameworks to manage risks associated with these inflows. According to the bank's March 2026 bourse filing, these include rigorous customer selection, risk scenario planning supported by early warning indicators, watch-listing, and regular stress testing. The IMF's assessment corroborates this, characterizing the local D-SIBs as having "ample capital and liquidity," maintaining strong credit ratings, and operating extensive regional operations across multiple jurisdictions, currencies, and regulatory environments.

Risks and Mitigants

Despite the positive trajectory, risks remain. DBS flagged in its filing that large deposit inflows could exert downward pressure on Singapore interest rates, compressing net interest margins. The bank also noted that market volatility stemming from the Middle East conflict might dampen investor sentiment and reduce wealth management activity, partially offsetting the fee income gains. Indeed, net interest income has eased slightly due to lower regional benchmark rates, though banks have mitigated this impact through active balance sheet management, including deposit cost optimisation, hedging, and asset repricing, according to SGX data cited by Asian Banking and Finance.

UOB Kay Hian's Koh warned that further escalation of the Middle East conflict remains a key risk, noting that "the conflict in the Middle East could lead to elevated inflation through energy and trade channels, although the persistence would depend on the scale and duration of the skirmishes." The global easing cycle, with narrowing interest rate differentials, supports continued safe-haven preference for SGD deposits, as FOZL Group analysts observe. The three-month compounded SORA has eased to approximately 1.03%, while the US Federal Reserve is expected to pause rate cuts in 2026 at around 3.5%, reflecting continued global uncertainty.

For investors and analysts monitoring Singapore's banking sector, the key variables are the trajectory of the Middle East conflict, the pace of global interest rate normalization, and whether non-interest income growth can sustainably offset compression in net interest margins.
