HSBC Holdings Chair Brendan Nelson stated Tuesday that a Middle East peace deal is essential for a substantial resumption of global energy flows, identifying oil-driven inflation as a major risk to the world economy. Speaking at the HSBC Global Investment Summit in Hong Kong, Nelson noted that persistent uncertainty will keep energy prices elevated. Oil prices have surged, nearing $100 a barrel, amid investor anticipation of prolonged tensions around the Strait of Hormuz, a critical chokepoint for global oil and gas.

Nelson cautioned that current global growth, trade, and inflation forecasts require "considerable caution" due to the unquantified impacts of the Iran conflict. "The longer the disruption continues, the more the indirect effects from higher energy costs will lift inflation and depress growth," he warned.

With the Strait of Hormuz unlikely to reopen swiftly, Nelson anticipates interest rates will remain steady in the U.S., Europe, and Britain this year. This outlook stems from tighter financial conditions driven by rising short- and long-term market rates. The U.S. Navy initiated a blockade of the strait following the collapse of talks to end a six-week war.
