Global markets broadly pulled higher on Friday, led by Hong Kong, as optimism grew about US-China trade talks and reports of damage to an Iranian oil tanker sent energy stocks spiking.

Hong Kong’s Hang Seng (HSI) Index closed 2.3% higher, logging its biggest daily increase in more than a month. Japan’s Nikkei 225 (N225) and South Korea’s Kospi rose 1.2% and 0.8%, respectively. China’s Shanghai Composite Index gained 0.9%, also its best daily performance in a month.

In Europe, Germany’s DAX (DAX) advanced 1.8% in early trading. France’s CAC 40 (CAC40) added 1.1%. The United Kingdom’s FTSE 100 (UKX) alternated between slight gains and losses.

Oil-related stocks around Asia posted big gains after a reported explosion damaged an Iranian oil tanker in the Red Sea, stoking fears about increased tensions in the region and potential disruption to oil supply.

CNOOC, China’s largest offshore oil producer, surged 4.7% in Hong Kong, also its best day in three weeks. PetroChina, Asia’s largest oil and gas producer, jumped 3.3%. Sinopec, the region’s top refiner, climbed 3.1%. Sinopec and PetroChina’s Shanghai-listed stocks also gained 1.6% and 1.3%, respectively.

Japanese oil producers Inpex and Japex rose 3.3% and 2.5% respectively in Tokyo.

Crude oil prices extended earlier gains on Friday after the news.

US oil prices rose 1.8% to $54.51 per barrel. Brent crude, the global benchmark, gained 1.7% to $60.12 per barrel.

US stock futures also rose further following overnight gains on Wall Street. Dow (INDU) and S&P 500 (SPX) futures both improved 0.9%, while Nasdaq futures moved up 1.1%.

President Donald Trump said Thursday in the United States that the first day of high-level trade talks with China was going “very well.” Officials later said there was better-than-expected progress during the discussions.

People close to the talks expect the momentum to continue Friday when Trump meets Chinese Vice Premier Liu He in the Oval Office.

Officials familiar with the talks say possible outcomes will likely fall short of a sweeping, comprehensive trade deal that Trump has called for. But smaller deal could include new currency agreements, Chinese commitments on farm purchases and a halt on US tariffs that are due to increase next week.

Separately, China’s state-run Xinhua News Agency reported late Thursday that Liu told several US business officials in Washington that he came to the United States with “great sincerity” for the talks. Xinhua reported that Liu is eager to discuss issues such as trade balance, market access and investor protection.
