Asian Markets Caught Between AI Doubts and an Oil Shock

Asian investors woke up this week to an unusual double squeeze. On one side, the artificial intelligence trade that has carried regional stock markets for two years is wobbling. On the other, oil has jumped back above 110 dollars a barrel after reports of tankers burning in the Strait of Hormuz. Thursday’s session showed what happens when both pressures hit at once: Seoul’s Kospi lost about three and a half per cent, Hong Kong’s Hang Seng around three per cent and Tokyo’s Nikkei close to the same.

Why Asia feels it first

Asian benchmarks are heavy with the companies that build the AI economy: memory makers in Korea, chip and equipment suppliers in Japan and Taiwan, platform giants in Hong Kong. When investors start asking whether data-centre spending can keep growing while borrowing costs rise, these are the stocks that get sold first. Tech-heavy indices in Hong Kong and Shenzhen fell harder than the broad market, a sign that this was a targeted retreat rather than general panic.

Energy adds a second layer. Most of the region imports the bulk of its oil and gas, much of it through the Gulf. Every spike in crude is effectively a tax on Japanese households, Korean refiners and Indian importers. It also complicates central banks’ plans. The Bank of Korea has sounded hawkish, the Philippines just lifted its key rate to 5.5 per cent to fight inflation, and the Bank of Japan is expected to sit tight. Higher energy costs make it harder for anyone to cut.

Correction, not collapse

It is worth keeping perspective. The Nikkei is still trading above 60,000 and the Kospi far above where it started the year. Some of this week’s selling is profit-taking after an extraordinary run. Investors are not abandoning AI; they are demanding proof that spending turns into earnings. Results that beat expectations still get rewarded, while plans that look like ever-bigger cheques for data centres are punished.

For ordinary savers in the region, the lesson is diversification. Portfolios that leaned entirely on chip stocks have had a rough week, while gold, short-dated bonds and some defensive sectors held up. Japan’s large insurers have been quietly adding gold for exactly this reason.

The coming weeks will hinge on two things that no one in Asia controls: whether shipping through Hormuz stabilises and whether big tech customers keep ordering. Until both become clearer, expect volatility to remain the region’s most reliable export.
