Asian stocks fell today as tensions with Iran weighed on markets.

Asia-Pacific markets were mostly lower on Tuesday, as investors monitored growing uncertainty surrounding negotiations between the United States and Iran. A cautious mood prevailed in the region's trading sessions, even after Wall Street hit new all-time highs, driven by the performance of technology companies.

In Japan, the Nikkei 225 index fell 1,32%, while the Topix registered a drop of 1,14%. In South Korea, the Kospi lost 1,92%, while the Kosdaq, which tracks smaller capitalization companies, showed a decline of 3,13%.

In Australia, the S&P/ASX 200 index also followed the negative movement of regional markets, falling 0,71%. Risk aversion gained strength amid concerns related to the Middle East and the potential impacts on global trade and energy prices.

Hong Kong stood out from the rest of the region. The Hang Seng index advanced 0,13%, while the CSI 300, which includes some of the largest companies listed on mainland China's stock exchanges, registered a gain of 0,1%.

Investors' attention remained focused on statements made by the current President of the United States, Donald Trump, regarding negotiations with Iran. During an interview with CNBC, the American leader downplayed the possibility of a failure in diplomatic talks.

"Honestly, I don't care if they break up."

“I really don’t care. I couldn’t care less,” Trump said, adding that the protracted negotiations “had started to get very boring.”

The statements came after reports that Iranian negotiators were considering halting discussions with Washington. The reports also pointed to the possibility of measures involving the Strait of Hormuz, one of the most important maritime routes for global oil transport.

The comments had repercussions on futures contracts for the main US indexes. S&P 500 futures were down 0,2%, while Nasdaq 100 futures registered a 0,3% drop. Contracts linked to the Dow Jones Industrial Average lost 122 points, equivalent to 0,2%.

While Asian markets showed caution, Wall Street had closed the previous session higher. The S&P 500 advanced 0,26%, closing at 7.599,96 points. The Nasdaq Composite rose 0,42%, to 27.086,81 points, while the Dow Jones Industrial Average gained 46,42 points, or 0,09%, closing at 51.078,88 points.

Nvidia stood out, leading gains in the technology sector after unveiling a new chip aimed at personal computers. The performance of these industry giants helped the three main US indices reach new intraday all-time highs and close at record levels, even amid rising oil prices and geopolitical concerns that continue to influence global investor sentiment, including cryptocurrency market participants.
