What happened

Asian stock markets experienced a period of volatility, with some indices hitting record highs in Japan and South Korea following a West Asia truce. However, shares later retreated amid thin holiday trading and concerns regarding the durability of the U.S.-Iran peace deal.

Coverage from CNBC, Reuters, and Bloomberg emphasizes a shift in sentiment as U.S.-Iran talks hit an early snag and were postponed. While a tech-led rally on Wall Street initially lifted moods, Reuters reports that stocks eventually turned lower.

Market observers are monitoring the trajectory of oil, which was on pace for a weekly decline according to Investing.com, and the ongoing status of the postponed diplomatic talks.
