On Thursday, Asia-Pacific markets experienced a widespread uptick, reflecting overnight advances on Wall Street fueled by growing optimism about a potential U.S.-Iran agreement.

Stocks have seen an upward trend this week, spurred by the prospects of a peace accord between the U.S. and Iran.

In an interview with Fox Business aired on Wednesday, President Donald Trump stated that the conflict with Iran is “very close to over,” asserting once again that Tehran is eager to “make a deal very badly.”
