Oil price spike rattles global markets as Middle East tensions escalate

Brent crude crossed $100 per barrel, triggering declines in major stock indices. The surge follows US strikes on Iranian oil carriers and Iranian retaliation. Analysts warn of rising inflation pressures and potential central bank tightening.
The US military struck five Iranian crude oil carriers overnight, prompting Iranian missile attacks on American forces in Jordan and on regional shipping. Secretary of State Marco Rubio stated Washington would continue targeting tankers in response to attempted attacks on US warships. Wall Street indexes posted modest losses, while European industrial and banking stocks fell to one-week lows; Asian markets were mixed, though technology shares recovered on AI-driven momentum.
Analysts view the $100 benchmark as a symbolic threshold, with one strategist suggesting crude must reach $150 to significantly dent demand. Rising diesel prices could feed into broader inflation. This inflationary pressure has led markets to anticipate the European Central Bank hiking rates on Thursday and the Federal Reserve considering a similar move next week, pushing benchmark bond yields in the US, Japan, and parts of Europe to multi-decade highs.
Persistently high energy costs could squeeze household budgets and raise operating expenses for transport and manufacturing sectors. Central banks may respond with tighter monetary policy, potentially slowing economic growth and increasing borrowing costs for governments and consumers. Prolonged geopolitical instability could further disrupt supply chains, making essential goods more expensive for the general public while straining financial institutions exposed to volatile bond markets.
