- MAS unexpectedly tightened monetary policy for a second consecutive meeting, increasing the rate of appreciation of the Singapore dollar's nominal effective exchange rate policy band "very slightly" — smaller than April's adjustment — confounding Reuters-polled economists who had forecast the bank to stand pat.
- Singapore's core inflation ticked up to 1.6% in June from 1.4% in May, with headline inflation at 1.9%, sitting near the bottom of MAS's 1.5%–2.5% full-year forecast range; OCBC projects both measures could overshoot to roughly 2.5% and 2.3% in coming months before subsiding below 2% only from the second half of 2027.
- Brent crude climbed back above $100 a barrel after Houthi militants attacked two Saudi tankers in the Red Sea, deepening supply threats that had eased before the Middle East ceasefire collapsed, with transportation fuel prices rising since the onset of the U.S.-Iran conflict.
- Singapore's GDP expanded 5.7% year-over-year in Q2, beating the 5.5% Reuters consensus estimate and well above the government's full-year 2%–4% projection, as AI-driven electronics exports offset broader economic turbulence.
- OCBC's Selena Ling told CNBC that "two straight policy tightenings mean the MAS will not become complacent about imported inflation," framing the move as a deliberate pre-emptive stance rather than a response to current price pressures.
Why it matters: Singapore's MAS is tightening into a red-hot economy — Q2 GDP grew 5.7% versus a 2%–4% full-year projection — because its near-total reliance on imported energy means Brent above $100 almost mechanically translates into consumer prices with a lag. The surprise decision, taken against a Reuters poll consensus for no change, signals the central bank will not wait for core inflation to break out of its 1.5%–2.5% band before acting, with OCBC tipping headline inflation to overshoot to 2.5% within months.
