The market cheered the reports, suggesting the US and Iran could engage in talks shortly to find a permanent solution to their conflict.

As Reuters reported, US President Donald Trump said talks with Iran could resume in Pakistan over the next two days.

Signs of diplomatic engagement calmed market nerves after the first round of talks over the last weekend between the parties failed to fetch a desired outcome.

Brent crude declined further to trade below the $95 per barrel level, boosting market sentiment.

Brent crude futures fell nearly 0.40% to $94 a barrel, after declining almost 5% in the previous session. US West Texas Intermediate crude dropped more than 1% to $90, following an 8% fall in the previous session after President Trump said that the talks to end the US-Iran war could resume in Pakistan over the next two days.

Major markets globally jumped higher as the prospect of the US-Iran talks resuming shortly lifted sentiment.

MSCI’s broadest index of Asia-Pacific shares outside Japan gained 1.5% to the highest level in six weeks. Japan’s Nikkei also rallied 1%, while Korea's Kospi jumped 3%.

Overnight, the US stock market clocked strong gains, with the Nasdaq climbing 2% and the S&P 500 rising 1.2%, nearing its record closing high.
