Driven by expectations of peace in the Middle East, global risky assets are collectively boiling. Asia-Pacific stocks were all in the red on Wednesday, with South Korea's KOSPI setting a new record high and triggering a circuit breaker, with SK Hynix's stock price soaring by 11% in a single day, with its market value breaking through one trillion dollars; the Nikkei 225 index also refreshed its record, continuing the strong rise of US stocks overnight.

Optimistic sentiment from the US-Iran agreement boosts global risky assets, with Asia-Pacific stocks rising across the board on Wednesday, with both Japan's and South Korea's benchmark indices hitting record highs, following the strong overnight rally of US stocks.

South Korea's Seoul Composite Index (KOSPI) rose up to 5% at one point during the day, setting a new record high again and triggering the circuit breaker mechanism again - the Korea Exchange suspended programmed trading for 5 minutes due to a 5% rise in KOSPI 200 futures.

The Nikkei 225 index also rose by 2%, similarly reaching a new historical high. The MSCI Asia-Pacific index rose by about 1% overall.

Expectations of progress in US-Iran ceasefire talks continue to boost market sentiment. US President Trump said that talks with Iran are "going smoothly," according to CCTV news, and Rubio said that the wording consultation of the US-Iran agreement may "still take a few days."

Driven by this, US stocks rose sharply overnight, with both the S&P 500 and the NASDAQ Composite closing at record highs. Chip stocks led the charge, with Micron Technology's stock price soaring by 19% in a single day, with its market value breaking through one trillion dollars.

SK Hynix's stock price once soared by 11% in a single day, with its market value breaking through the one trillion dollar threshold, joining the global club of trillion-dollar market value companies. This trend highly resonates with the chip stock performance of US stocks overnight. Micron Technology's strong performance led the NASDAQ 100 index to rise by 1.8%, also closing at a historical high, with the transmission effect of tech stocks on the global market being significant.

In Japan, the Nikkei 225 index rose by about 2%, the Tokyo Stock Exchange Index (Topix) rose by 0.57%, and Australia's S&P/ASX 200 index rose slightly by 0.13%.
