The dominant macro driver overnight was a double-barrelled US inflation shock: May CPI accelerated to 4.2% year-on-year — the fastest pace since April 2023 — while headline PPI surged 1.1% month-on-month against a 0.7% consensus, pushing annual wholesale price growth to 6.5%. The 2-year Treasury yield rose 7 basis points to 4.05% and the 10-year climbed 2 basis points to 4.47%, with Fed funds futures now pricing approximately 70% odds of at least one rate hike in 2026, with October emerging as a live meeting at nearly 50% probability. The Fed funds target range currently sits at 3.50%–3.75%, and PCE-proxy components within PPI — particularly core ex-food, energy, and trade at +0.8% month-on-month, among the three strongest monthly readings on record — suggest the Fed's preferred inflation gauge will also print firm. Compounding the inflationary backdrop, Iran has maintained its closure of the Strait of Hormuz following a second consecutive day of US military strikes, keeping Brent crude at $88.72/bbl even after a session pullback of 4.70%.
For Asia-Pacific investors, the cross-asset transmission is concentrated in three areas. First, the yen: USD/JPY sits at 159.88, with CFTC data showing net short yen positions at $10.1 billion — a level last seen in July 2024 immediately before a coordinated intervention and BoJ hike triggered a violent carry trade unwind. A widely-expected BoJ rate hike to 1.0% at the 15–16 June meeting, complicated by Governor Ueda's hospitalisation, is the single most potent near-term catalyst for regional volatility, and the Nikkei VIX surging 16.42% to 38.01 reflects that anxiety directly. Second, Korean and Taiwanese semiconductor indices are absorbing the dual shock of a hawkish Fed repricing and Broadcom's weak forecast, with KOSPI down 4.52% and TWSE off 3.31%, as Samsung Electronics and SK Hynix — together comprising 42.2% of KOSPI — face sector-wide pressure. Third, the aluminium complex is flagging industrial demand concern, with LME aluminium off 6.12% to $3,548.25/t, a signal closely watched by Australian materials producers, even as gold at $4,234.30/oz and copper at $6.3935/lb point to continued safe-haven and infrastructure-demand support.
