Brent crude finished nearly 4% higher above US$99 a barrel, while US benchmark West Texas Intermediate traded above US$93 a barrel.\n\nAsian equity futures pointed to a firmer open on Wednesday, suggesting investors remain optimistic that diplomatic efforts between Washington and Tehran could still produce a broader agreement despite the latest military escalation.\n\nFutures linked to Japan’s Nikkei 225 and China’s CSI 300 were each around 0.5% higher in early trading, while contracts tied to Hong Kong and Australian markets were broadly flat."}
