Goldman Sachs flagged risks to global energy supply amid concerns over a potential disruption in the Strait of Hormuz that would lead to significant spikes in oil and natural gas prices, the bank said in a note dated Sunday.

Washington's strikes on Iran stoked fears that Iran could retaliate by closing the Strait of Hormuz, a waterway between Iran and Oman through which around 20 per cent of the oil and gas consumed globally flows.

Fears of a major oil supply shock are mounting as tensions escalate in the Strait of Hormuz, a vital artery for nearly 20% of global crude shipments, with Wall Street racing to assess the potential price impact after the U.S. struck Iran over the weekend.
