Executive Summary
This case study examines the potential implications of implementing a 10% credit card interest rate cap in Singapore, modeled after President Trump’s January 2026 proposal in the United States. The analysis reveals that such a policy would trigger unprecedented disruption in Singapore’s highly sophisticated credit card rewards ecosystem, disproportionately affecting middle-income consumers while potentially benefiting only a small segment of debt-carrying cardholders.

2. Impact Assessment
2.1 Consumer Impact
Winners (Estimated 15-20% of cardholders)
Chronic Balance Carriers
- Those consistently carrying balances above SGD 5,000
- Would save SGD 800-1,200 annually per SGD 5,000 in debt
- Typically lower-income households or those experiencing financial distress
- Example: SGD 10,000 balance at 26% EIR = SGD 2,600/year interest vs. SGD 1,000 at 10% cap (saves SGD 1,600)
Losers (Estimated 80-85% of cardholders)
Responsible Users Who Pay in Full
- Currently pay zero interest but maximize rewards
- Would lose substantial value from rewards devaluation
- Cannot switch to alternative products without losing benefits
- Example: Family earning 200,000 miles annually (worth SGD 4,000+ in premium cabin flights) could see this drop to 50,000 miles (worth SGD 800-1,000)
Middle-Income Young Professionals
- Current minimum income requirements: SGD 30,000-50,000
- New requirements likely: SGD 80,000-120,000+
- Would lose access to meaningful rewards programs entirely
- Affects career starters, young families planning annual trips
Miles Optimizers
- Sophisticated users managing 3-5 cards strategically
- Currently achieve 3-6 free business/first class tickets annually
- Would see program complexity disappear, making optimization impossible
- Represents estimated 100,000-200,000 active miles enthusiasts
2.2 Banking Sector Impact
Revenue Loss
Interest Income Reduction
- Estimated 60-65% decrease in credit card interest revenue
- Banks currently earn approximately SGD 1.2-1.5 billion annually from card interest
- Potential loss: SGD 700-900 million annually across the sector
- DBS, UOB, OCBC would each face SGD 150-250 million in lost revenue
Compensatory Measures Required
- Need to recover SGD 700-900 million through fees and reduced rewards
- Drastic restructuring of card portfolios
- Potential workforce reductions in cards and loyalty divisions
Strategic Responses
Portfolio Rationalization
- Reduction from 30-50 cards per bank to 5-10 specialized products

SIA Revenue Implications
Partnership Revenue at Risk

Broader Economic Implications
Consumer Spending Patterns
- Rewards-driven spending could decline 5-10%
- Shift from credit cards to debit cards and cash

4. Solutions & Mitigation Strategies
4.1 For Policymakers
Alternative Policy Approaches
Progressive Rate Caps Rather than uniform 10% cap, implement tiered structure:
- Basic cards (no annual fee): 15% cap
- Standard rewards cards (annual fee < SGD 200): 18% cap
- Premium cards (annual fee > SGD 200): 22% cap
- Ultra-premium cards (annual fee > SGD 500): 25% cap
Benefits: Preserves rewards ecosystem while providing relief to vulnerable consumers. Allows market segmentation to continue functioning.
Income-Based Rate Caps Cap rates based on cardholder income brackets:
- Income < SGD 50,000: 12% cap
- Income SGD 50,000-100,000: 18% cap
- Income > SGD 100,000: Market rates
Benefits: Targets protection to those most likely to struggle with debt while preserving programs for those who don’t need protection.
Opt-In Premium Pricing
- Default 10% cap for all consumers
- Allow consumers with income > SGD 80,000 to opt into higher rates in exchange for rewards
- Requires annual reconfirmation and financial literacy certification

5. Regional Competitive Implications
5.1 Singapore vs. Regional Markets
Hong Kong
- If Singapore implements cap but Hong Kong doesn’t: brain drain of premium customers
- Hong Kong cards could be marketed to Singapore residents
- Singapore loses competitive advantage in financial services
Malaysia
- Already has lower rewards programs; gap would narrow
- Could attract Singapore banking activity for rewards-focused consumers
- Cross-border card applications may increase
Thailand, Indonesia
- Less developed rewards ecosystems; Singapore loses differentiation
- Regional financial hub status diminished
5.2 Recommendations for Maintaining Competitiveness
Regional Coordination

- Prevent regulatory arbitrage and race to bottom
- Maintain Singapore’s premium positioning
Strategic Carve-Outs
- Exempt foreign currency cards used primarily outside Singapore
- Preserve advantage for regional business travelers, expatriates
- Maintain appeal of Singapore banking relationships
6. Conclusion & Key Recommendations
For Government/MAS
- Don’t implement a uniform rate cap – the costs vastly exceed benefits for Singapore’s unique market
- If consumer protection needed, use targeted interventions: debt counseling, payment plans, income-based caps
- Preserve strategic partnerships with SIA through subsidies if necessary
- Conduct comprehensive cost-benefit analysis including tourism, aviation, fintech competitiveness
- Extended consultation period with industry, consumers, international partners
For Banks
- Diversify revenue models away from interest income immediately
- Invest in charge card infrastructure for high-value customers
- Deepen deposit relationships to fund rewards through NIM
- Communicate transparently with customers about changes
- Collaborate on industry solutions rather than compete destructively
For Singapore Airlines
- Accelerate diversification of loyalty program revenue
- Strengthen direct customer relationships independent of banks
- Develop new partnership models based on spending volume, not miles issued
- Prepare for managed devaluation if necessary
- Invest in technology for dynamic pricing and personalization
For Consumers
- Assess your personal impact – are you a balance carrier (winner) or responsible user (loser)?
- Act quickly if cap appears likely – maximize current programs
- Don’t carry balances hoping to benefit from cap; rewards loss will exceed interest savings for most
- Explore alternatives – cashback, BNPL, digital wallets, direct loyalty
- Provide feedback to banks and policymakers about preferred solutions
Final Assessment
A 10% credit card interest rate cap, while politically appealing as consumer protection, would be economically destructive for Singapore’s sophisticated financial services ecosystem. The policy would primarily benefit a small minority of chronic debt carriers while severely harming the majority of responsible users who currently enjoy world-class rewards programs at zero cost.
Singapore’s unique position as a financial hub, aviation center, and high-income society means the negative consequences would be magnified compared to larger, more diverse economies. The optimal path forward involves targeted consumer protection measures that don’t destroy value for the 80% of users who never pay interest.
Policymakers should ask: Is it worth eliminating SGD 3-5 billion in annual consumer value (rewards) to save SGD 700-900 million in interest costs for debt carriers—especially when alternative solutions could help those consumers without collateral damage?
The answer, based on this analysis, is no. Singapore should pursue smarter, more targeted interventions that protect vulnerable consumers without dismantling one of Asia’s most valuable and sophisticated financial ecosystems.
