Oil prices swung sharply at the start of the week, spiking overnight before easing back on Monday in a move that helped to calm jittery stock and bond markets around the world.
The retreat came as a relief to investors after a turbulent stretch in which the price of crude has become one of the dominant forces in financial markets. Oil has stayed elevated since the closure of the Strait of Hormuz, the conduit for a large share of the world’s seaborne crude.
The overnight scare, and its rapid reversal, underlined how tightly markets are now tracking every development in the Gulf. Brent crude has traded well above $100 a barrel for weeks, a level that has fed fears of renewed inflation across the major economies.
Those fears have been transmitted most directly through the bond market. Last week, worries about war-stoked inflation drove a sell-off in government debt, pushing yields higher and unsettling equities; Monday’s softer oil price allowed some of that pressure to drain away.
The episode highlighted an unusual dynamic in which a commodity, rather than central-bank policy, has become a principal swing factor for interest-rate expectations. Each move in crude now ripples quickly through currencies, bonds and shares.
Analysts cautioned that the calm could prove short-lived. With the conflict between the United States and Iran unresolved and the Strait of Hormuz still closed, the risk of another sudden spike remains, and traders are likely to stay defensive until the outlook clears.
