Three months into the Iran war, crude prices have jumped roughly 40%, with oil now trading well above $100 per barrel.

Governments released 400 million barrels from strategic reserves to cushion the blow, but bond markets are pricing in persistent price pressure. Treasury yields are rising as investors demand higher returns to hold bonds amid geopolitical uncertainty.

Oil’s Shock to the Global System

Crude prices roughly doubled from pre-war levels in early April before settling above $100 per barrel. A record 400-million-barrel release from strategic reserves of major economies, together with traders finding alternative sources, has helped ease the immediate supply shock. But the strain on the global energy system is growing, and energy costs remain elevated worldwide.

Inflation Fears Delay Rate Cuts

UK inflation stood at 2.8% in April, still above the Bank of England’s 2% target. The bank warned that inflation could reach 6% in a worst-case scenario due to the war’s impact on energy costs. Six rate cuts since August 2024 had brought UK rates to 3.75%, but the war is expected to delay further falls. G-7 finance chiefs are working to look through bond volatility as yields climb.

Bond Portfolios Face Pressure

Rising yields have pushed bond prices lower. The iShares 0-3 Month Treasury Bond ETF (SGOV) recorded a 0.27% drawdown over three months and trades near $100.67, with a 52-week range of $100.28 to $100.74. Investors are demanding higher compensation for holding bonds as inflation risks persist. A 2020 chart pattern that destroyed bond portfolios may be returning as geopolitical pressures continue to mount.

Dollar Strengthens as Safe Haven

The US dollar has emerged as a winner from the conflict, with investors embracing its safe-haven status. Higher treasury yields attract foreign capital seeking returns in US assets. This dynamic supports the dollar even as other currencies slide, particularly in Asian economies grappling with currency weakness and inflation concerns.
