Saxo's Asia Market Quick Take confirmed that "markets recovered on soft CPI print" and that the subsequent weaker dollar lifted G10 and emerging-market currencies broadly .

Regional Index Performance by the Numbers

South Korea's KOSPI was the standout performer, closing at approximately 7,421 points for a gain of 8.23% on the day . An AP report cited a slightly different close of +7.1% at 7,343.37, reflecting intraday volatility . The move was fueled by net foreign investor purchases of approximately 2.5 trillion Korean won . The index had been hammered in prior weeks by a chip-sector sell-off that saw it plunge nearly 9% in a single session just days earlier .

Other major benchmarks saw more modest gains:

• Japan's Nikkei 225 rose 0.30%, and the broader TOPIX gained 0.23% .
• China's Shanghai Composite advanced 1.36% to 3,967.13 .
• Hong Kong's Hang Seng Index—which had been lagging regional peers in prior sessions—did not have a specific close reported for July 15 in available sources, but broader regional data shows it recovered less aggressively than Seoul and Tokyo .

Sector-Specific Movements: Semiconductors Lead

The KOSPI's surge was explicitly attributed to a dramatic rebound in U.S.-origin semiconductor stocks. SK Hynix's American Depositary Receipt (ADR) had jumped over 27% on the New York Stock Exchange the previous night, and AI-chip heavyweights NVIDIA and Micron also rallied, directly catalyzing the recovery in investor sentiment . The AP report confirmed that South Korean semiconductor stocks rebounded sharply from their recent sell-off .

Financials also contributed. Strong earnings reports from major U.S. banks, which closed higher Tuesday in New York, boosted sentiment for Asian banking stocks .

The oil-sensitive sectors were mixed. Crude oil took a brief breather after the U.S. scrapped a plan to levy shipping through the Strait of Hormuz, which lifted air and transport stocks . However, a concurrent spike in Brent crude to above $85–$86 per barrel—driven by escalating U.S.–Iran conflict and tanker attacks in the region—created headwinds for Indian and other oil-importing markets .

Context: A Sentiment-Driven Rebound After a Sharp Sell-Off

The rally must be seen in context: the prior week had seen some of the most dramatic volatility in Asian markets in 2026. The KOSPI had fallen nearly 9% on Monday, July 13, in its worst session in years, triggered by a leveraged unwind in SK Hynix and other Korean memory-chip names . The softer U.S. CPI print and Wall Street's strong close gave investors a reason to rotate back into those beaten-down technology shares, particularly in the AI and semiconductor sectors .

As TickMill market analyst Patrick Munnelly put it: "Traders are buying equities at a discount following the recent sharp sell-off" .

Summary

The July 15 rally was a broad, sentiment-driven rebound. The soft U.S. inflation print was the macro trigger, Wall Street's strong close was the transmission mechanism, and the semiconductor/AI sector—which had been oversold in prior weeks—was the primary engine of gains, especially in South Korea's KOSPI.
