Executive Summary
This case study examines the potential impact of a hypothetical 10% credit card interest rate cap on Singapore’s three major banks (DBS, OCBC, UOB), drawing lessons from Trump’s January 2026 proposal that sent U.S. bank stocks tumbling. The analysis provides outlook scenarios, strategic solutions, and quantified impacts specific to Singapore’s banking landscape.

9. Conclusion: The Singapore Advantage
While a credit card interest rate cap would create short-term disruption for Singapore banks, several factors suggest manageable impact and successful adaptation:
Mitigating Factors Unique to Singapore:
- Strong Bank Fundamentals
- High capital ratios (14-16% CET1)
- Diversified revenue streams (credit cards only 5-8% of total)
- Excellent asset quality
- Strong profitability cushions
- Sophisticated Regulatory Environment
- MAS’s consultative approach prevents shock implementations
- Track record of balanced regulation
- Strong coordination between banks and regulators
- Focus on systemic stability
- Affluent Customer Base
- Higher average income reduces credit risk
- Lower revolving balance rates than U.S.
- Greater willingness to pay for premium services
- Strong savings culture
- Digital Leadership
- World-class banking technology infrastructure
- High digital adoption rates (85%+ active digital users)
- Strong fintech ecosystem for partnerships
- Government support for innovation
- Regional Opportunities
- ASEAN expansion potential
- Cross-border wealth management
- Singapore’s role as financial hub
- Regulatory arbitrage possibilities
Final Assessment:
Probability of Implementation: <10% Impact if Implemented: Moderate to High (short-term), Low to Moderate (long-term) Recovery Timeline: 24-36 months to full profitability restoration Overall Risk Rating: MEDIUM
Singapore banks are well-positioned to weather such a policy change through their strong fundamentals, innovative capacity, and supportive regulatory environment. The Trump announcement serves as a valuable case study for scenario planning, but the likelihood of similar action in Singapore remains low given the city-state’s market-oriented approach and emphasis on regulatory stability.
The key lesson: Even in low-probability scenarios, preparation and strategic agility determine outcomes. Singapore banks that invest now in digital transformation, product innovation, and regional expansion will be best positioned for any regulatory environment.
