According to OCBC’s Christopher Wong, the USD/SGD currency pair rebounded overnight as a result of stalled US–Iran ceasefire talks, with technical indicators showing fading bearish momentum and a rising Relative Strength Index (RSI) [1]. Wong identifies resistance levels for USD/SGD at 1.2750/60 (50-day moving average, 50% Fibonacci retracement), 1.28 (21- and 100-day moving averages, 38.2% Fibonacci retracement of the 2026 low to high), and 1.2850 (200-day moving average, 23.6% Fibonacci retracement). Key support is noted at 1.2670 (76.4% Fibonacci retracement), with further support at 1.2620 and 1.2590 if a decisive break occurs [1].
Wong describes the Singapore Dollar (SGD) as having acted as a regional defensive currency during the Iran-war shock phase (from 1 March to before the ceasefire announcement), outperforming most Asian peers such as the Japanese Yen (JPY), South Korean Won (KRW), Thai Baht (THB), Philippine Peso (PHP), and Malaysian Ringgit (MYR) [1]. He notes that SGD's resilience is likely to persist as long as geopolitical uncertainty sustains demand for lower-beta Asian currencies [1].
However, Wong cautions that once immediate geopolitical stress fades and markets rotate back into pro-cyclical and trade-sensitive currencies—particularly those linked to technology, global growth, and broader risk recovery—the SGD may lose its relative strength. In such a scenario, higher-beta currencies like the MYR, KRW, Australian Dollar (AUD), and Taiwan Dollar (TWD) could outperform the SGD as markets shift from a defensive to a rebound posture [1].
CONCLUSION
The USD/SGD has shown resilience amid geopolitical uncertainty, but OCBC analysts suggest this defensive strength may wane if market sentiment shifts toward risk-on assets. Investors should monitor key technical levels and be prepared for potential outperformance from higher-beta Asian currencies should geopolitical tensions ease.
