Japanese markets surged to record levels on Tuesday as investors responded positively to reports of an extended ceasefire between the United States and Iran. The Nikkei 225 index closed at an all-time high, reflecting broader market optimism about reduced geopolitical tensions in the Middle East.

Commodity markets showed mixed reactions to the ceasefire developments. Gold prices rose as traders sought safe-haven assets, while oil prices weakened amid reduced concerns about supply disruptions from the strategically important region. The divergent moves reflect uncertainty about the durability of the diplomatic arrangements.

Separately, former President Trump indicated that the US had intercepted what he described as a Chinese "gift" intended for Iran, suggesting ongoing tensions despite the ceasefire. Bloomberg reported that Iranian oil tankers have been attempting to evade US maritime enforcement by disabling tracking systems while carrying crude oil shipments.

The Trump administration is also reportedly considering extending shipping waivers that would facilitate US oil exports, according to Axios. Such measures could further influence global energy markets as geopolitical dynamics continue to evolve in the region.

Market analysts noted that while the immediate ceasefire news provided relief to investors, underlying tensions between the US and Iran remain unresolved. The sustainability of current arrangements will likely depend on broader diplomatic efforts and compliance with existing international sanctions regimes.
