The dominant macro driver overnight was the US Treasury's announcement that it will more than double long-dated debt buyback operations from $2 billion to at least $4 billion per operation beginning September 9, which pulled 30-year Treasury yields down roughly 8-9 basis points toward 5.19-5.20% from near multi-decade highs around 5.34%. Simultaneously, Fed minutes released during the session struck a distinctly hawkish tone, with many policymakers signalling further rate hikes remain on the table if inflation fails to recede, specifically naming Middle East geopolitical tensions and the AI investment boom as upside inflation risks. Gold surged 2.83% to $4,489 per ounce and WTI crude held above $85 per barrel, reflecting a market simultaneously pricing safe-haven demand and persistent geopolitical supply disruption risk around the Strait of Hormuz. The VIX fell 6% to 14.89, suggesting US equity participants absorbed the Fed hawkishness with relative calm, helped by the buyback-driven bond relief.
For Asia-Pacific markets opening today, the picture is considerably more mixed than the subdued US session move implies. The Nikkei 225 dropped 3.16% with its own volatility gauge — the Nikkei VIX — surging 6.33% to 32.44, a sharp divergence from the relatively contained US VIX, pointing to acute regional stress likely amplified by USD/JPY pushing higher to 159.55 and ongoing semiconductor sector pressure. The KOSPI fell a significant 5.80%, underscoring that the chip and technology selloff that clipped US names like LRCX, STX and DELL hit Asian hardware and semiconductor-exposed markets far harder. The ASX 200 eased 0.18% with its VIX at a relatively calm 10.68, but Australian investors open today into a global backdrop where RBA Deputy Governor Andrew Hauser's recent hawkish commentary on upside inflation risks from energy and AI remains live, gold and oil strength offer commodity tailwinds, and the sharp Asian tech correction warrants close attention for locally-listed technology and growth names.
