Asia-Pacific markets traded mixed on Tuesday following a volatile trading session, as investors assess Iran war-related developments with the U.S. deadline for a ceasefire deal approaching.

U.S. President Donald Trump threatened to target Iran’s civilian infrastructure if a peace deal is not reached by Tuesday 8 p.m. ET, while also signaling that the Iranian leadership was negotiating in earnest.

Trump reiterated his demand for Iran to open the Strait of Hormuz, which would allow traffic to start flowing again through the vital route for global energy supplies — warning the U.S. would decimate every bridge and power plant within four hours of that deadline not being met.

The U.S. and Iran are weighing a framework plan to end their 5-week-old conflict, with Tehran pushing back against Trump’s pressure to swiftly reopen the Strait of Hormuz under a temporary ceasefire, and repeating its demand for a lasting end to the war.

Iran has rejected the U.S. ceasefire proposal and floated its own 10 points, including an end to hostilities in the region, a protocol for safe passage through the Strait of Hormuz, lifting of sanctions, and reconstruction, according to Axios.

Trump responded to the proposal, saying that “They made a … significant proposal. Not good enough, but they have made a very significant step. We will see what happens.”

The West Texas Intermediate crude futures rose 2.3% at $115 per barrel as of 3:28 p.m. ET. Brent crude gained about 1.5% at $111.37 a barrel.

Australia’s S&P/ASX 200 advanced 1.74% to end the session at 8,728.8. Japan’s Nikkei 225 barely budged, finishing the day 0.03% higher at 53,429.56, while the broad-based Topix gained 0.25% at 3,654.02.

South Korea’s blue-chip Kospi was up 0.82% at 5,494.78, and the small-cap Kosdaq lost over 1% to finish at 1,036.73.

Mainland China’s CSI 300 was unchanged at 4,440.62, and Hong Kong markets remained closed on Tuesday for the Easter holiday.

India’s Nifty 50 reversed earlier losses to rise 0.23% and Sensex was up 0.25%, tracking volatile trading in other Asian markets.

“As the deadline approaches, [Trump] wants to apply even more pressure to get them across the finish line,” Brian Jacobsen, chief economic strategist at Annex Wealth Management.

The headline-driven sharp swings in the markets, however, have created opportunities for investors to reshuffle their portfolios for longer-term returns, Jacobsen said. “When geopolitical worries hit the market, it tends to move prices indiscriminately. That’s when a discriminating investor can upgrade their portfolio.”

Jacobsen pointed to “decent entry points” in companies across industries, including utilities, financials, industrials, and technology, while naming defense and energy companies as the “first-order” beneficiaries in the wake of the conflict.
