Renewed crude oil surge and unresolved Middle East conflict hammer Asia-Pacific benchmarks on March 12, with energy-dependent economies bearing the brunt
Asian stock markets fell sharply on Thursday, with nearly every major index closing lower as a rebound in crude oil prices and deepening uncertainty over the U.S.-Israel-Iran conflict wiped out earlier optimism and sent investors into retreat across the region.
The selloff was broadest and deepest in markets most exposed to energy imports. Japan’s Nikkei 225 led losses in point terms, shedding 848.22 points to close at 54,177.15, a decline of 1.54%. Taiwan’s benchmark fell the hardest in percentage terms, dropping 1.88% — losing 641.37 points to finish at 33,472.82 — as semiconductor-linked stocks came under pressure from both energy cost fears and global risk-off sentiment.
Australia’s ASX 200 dropped 1.62%, falling 141.6 points to 8,601.9. South Korea’s KOSPI lost 1.23%, shedding 68.98 points to close at 5,540.97. Hong Kong’s Hang Seng declined 1.13%, down 293.12 points to 25,605.64.
Smaller markets were not spared. New Zealand’s NZX 50 shed 0.91%, dropping 120.27 points to 13,172.86. Shenzhen fell 0.94%, losing 135.679 points to close at 14,329.731. Malaysia’s index slipped 0.58%, down 9.88 points to 1,698.9. China’s Shanghai Composite was the relative outperformer, declining just 0.19%, or 7.901 points, to 4,125.532.
Oil’s Comeback Kills the Relief Rally
The proximate trigger for Thursday’s declines was a sharp reversal in crude oil prices. After Brent crude pulled back toward the $87–88 per barrel range on Monday and Tuesday — briefly lifted by comments from U.S. President Donald Trump suggesting the Iran conflict could end “soon” — prices climbed back aggressively toward the $91–98 range by Thursday morning Asia time.
That reversal landed like a gut punch for an already fragile region. Japan, South Korea, Taiwan, and Australia are among the world’s largest per-capita oil importers, and any sustained move higher in crude translates directly into wider trade deficits, inflationary pressure, and margin compression for manufacturers and exporters. Even a coordinated announcement of strategic reserve releases — reportedly up to 400 million barrels from IEA member nations including the U.S. and Japan — failed to meaningfully cap the upside, as markets remained skeptical that short-term supply injections could offset a prolonged conflict.
Geopolitical Fog Keeps Risk Appetite Suppressed
Beneath the oil story lies a more intractable problem: nobody knows how long the Middle East conflict lasts. The U.S.-Israel-Iran war, which escalated sharply in early March, has generated wildly conflicting signals. Trump’s public optimism has repeatedly been undercut by reports of extended operations, unresolved negotiations, and continued risks to Strait of Hormuz shipping lanes — through which roughly a fifth of the world’s seaborne oil passes.
For Asia’s export-heavy markets, that uncertainty is doubly damaging. It raises input costs at the same moment it pressures global demand. Investors responded the way they typically do in this environment: selling cyclicals, trimming tech exposure, and rotating toward defensives and cash.
The Broader Picture
U.S. equity futures pointed lower in early trade, with S&P 500 futures down roughly 0.8%, offering no tailwind from the West. Foreign institutional outflows from emerging markets continued, adding currency pressure on top of equity weakness.
The session was a reminder that the brief calm earlier this week was just that — brief. Until the conflict trajectory becomes clearer and oil finds a stable ceiling, Asia’s most energy-vulnerable markets — Japan, Taiwan, South Korea — are likely to remain the most exposed to further downside.
