What's happening

A synchronized global bond rout erupted Friday as oil price spikes tied to Iran war supply disruption triggered inflation fears across every major economy. US Treasury yields rose sharply, the British pound fell to its worst week since 2024 on gilt weakness, and Japanese government bond yields hit multi-year highs despite the BOJ's recent rate hike signals. The risk-off shift is dramatic: after weeks of AI-driven equity rallies, bonds are now the swing trade, with every inflation reading (US CPI beat, UK labour data, Japanese producer prices up 12-year high) pushing yields higher.

Oil is the mechanical driver. Brent crude surged above $95 on Iran supply shock, forcing up CRB commodity indices and pushing back Fed rate-cut expectations into late 2026 at earliest. SocGen's Albert Edwards is now calling for double-digit inflation making a comeback; T. Rowe Price's Sébastien Page says inflation hedging is the main risk in financial markets. India raised fuel prices for the first time in four years. Brazil, Romania, and other EM economies face stagflation risk, with central banks now caught between rate-hiking duties and growth concerns.

Equity rally momentum stalled visibly: S&P 500 futures fell 1% early Friday, Kospi briefly touched record 8K but reversed, EM stocks slumped most in a month. The bond move is structural, not cyclical: RBC's Lori Calvasina flagged that a 5% Treasury yield would depress P/E multiples; BofA's Hartnett called June profit-taking likely. Volatility (VIX) remains subdued, but curve flattening and cross-asset dislocations are widening. Pakistan announced new LNG imports from Persian Gulf on geopolitical clout; UAE is building Hormuz-bypass pipeline by 2027, signaling long-term energy shock.

Bulls argue this is transitory: oil supply shock will fade once geopolitics stabilize, and AI capex demand will offset rate headwinds. Energy importers face margin pressure but defence/infrastructure names benefit from risk premium. However, the 10Y Treasury broke above 4.5% and kept rising, suggesting institutional repositioning into higher-for-longer rates. Fed Chair Warsh's first days will be dominated by inflation firefighting, not the market-friendly pivot many expected. Crypto was resilient (BTC held $80K), but equities face a summer of multiple compression if oil stays elevated.
