US-Iran geopolitical tensions remained the dominant macro driver through the week ending 21 August, with President Trump threatening sweeping sanctions and 'economic warfare' over stalled Strait of Hormuz talks, pushing Brent crude to a one-month high near $95/bbl — a gain of roughly 6% for the week — before modest profit-taking into Friday's close. Central banks across the major economies maintained hawkish postures: the RBA held at 4.35% with an explicit preparedness to tighten further, the Fed held but featured hawkish dissents on inflation risks, and Japan's accelerating CPI print of 1.9% year-on-year reinforced expectations of further BoJ tightening. US Treasury yields remained elevated — the 10-year at 4.69% and the 30-year at 5.23% — with Treasury Secretary Bessent's expanded longer-term debt buyback programme offering only limited relief to bond markets, while the VIX eased 5.5% to 15.13, suggesting some stabilisation in risk sentiment heading into the weekend.
The cross-asset picture heading into Monday's Asia-Pacific open is one of cautious relief rather than conviction: Wall Street posted Friday gains — S&P 500 +0.43%, Dow +0.98% — but still closed the week lower by 1.6–2.8% across major indices, leaving regional markets to navigate elevated yields and energy-driven inflation concerns. Gold surged 2.39% to $4,624/oz on safe-haven demand, copper rose 1.85%, and aluminium jumped 4.76%, providing a broadly constructive backdrop for ASX-listed resource and precious metals names. The AUD/USD lifted 0.74% to 0.7172, which will temper some of the commodity price tailwind for unhedged Australian exporters, while the ASX VIX falling 3.13% to 10.51 suggests local volatility expectations remain contained despite the macro noise.
