Executive Summary
USD/SGD trades at 1.2710, near its lowest level since October 2014 following a ~6.6% SGD appreciation from the October 2025 high of ~1.36. Over the past year, USD/SGD has fallen approximately 5.2% (USD down, SGD up), with the decline accelerating in Q1 2026 as the DXY broke below 100 and Singapore's semiconductor-driven GDP surged to 6.9% YoY in Q4 2025. The Iran-US war (launched February 28) created a transient reversal to 1.2856 — USD/SGD's only meaningful bounce in the entire downtrend — before the pair retraced back to 1.2710 as ceasefire signals emerged. The dominant bilateral narrative is a structural USD depreciation cycle colliding with an equally structural SGD appreciation regime: the Fed is on an easing path against a backdrop of stagflationary deterioration (NFP -92K, core PCE 3.0%), while MAS holds an appreciating S$NEER band with 47% market probability of a slope increase at the April review. The bilateral rate differential of -283bps (SORA vs Fed Funds) is deeply negative for SGD carry but is overwhelmed by Singapore's 18% of GDP current account surplus — the largest in the G10+SGD universe — and structural capital inflows from the family office/wealth management channel backed by US$18bn in MAS reserve accumulation over five months. The headline stance is Bearish USD/SGD (pair falls = SGD strengthens) at both tactical and strategic horizons, with conviction rising from 3/5 tactically to 4/5 strategically as the oil shock headwind fades and the external surplus, semiconductor cycle, and Fed easing path dominate.
