The US says attacks on Iran have been halted to give "talks some space", raising hopes of a resolution to the conflict.

The price of oil has fallen sharply on hopes that a pause in attacks between the US and Iran could help lead to a resolution to the conflict. Brent crude, the global benchmark for oil, sank more than 9% to below $88 a barrel at one point, marking a sharp turnaround from last week when it had risen above $100. The fall came after the US ambassador to the UN said attacks on Iran had been halted for a second night in a row to give "talks some space". An Iranian army spokesperson said on Sunday that Tehran had halted "retaliatory" attacks in the region in response. The outbreak of the Iran war triggered a sharp rise in oil prices as the conflict led to the effective closure of the Strait of Hormuz, a key shipping route which usually carries about 20% of the world's oil and liquefied natural gas (LNG). When Iran and the US signed a memorandum of understanding in June to halt military operations and reopen the strait, the price of oil fell back to pre-war levels of around $70 a barrel. However, the collapse of the ceasefire earlier this month reignited fears over global energy supplies and pushed the oil price back up. Last week it hit $100 a barrel for the first time since May, with added concerns coming after Houthi militia in Yemen attacked oil tankers in the Red Sea, threatening a key export route that Saudi Arabia had used to bypass the Strait of Hormuz.
