Oil Surges Past $90 as Gulf Tensions Spike, Dragging Asian Shares — India’s Sensex Falls Over 600 Points

When the headline‑making strike on Iran entered its ninth consecutive day on Monday, traders across Asia woke up to a familiar, uneasy feeling. Oil, that ever‑watchful barometer of geopolitical risk, jumped past the $90‑per‑barrel mark – Brent settled at $90.40 and U.S. WTI at $84.39. The price hike, though seemingly modest in percentage terms, felt like a punch to markets that have been tip‑toeing around the Strait of Hormuz ever since shipping traffic dried up, with only four vessels managing to squeeze through on Sunday.

In India, the shock was immediate. By 9:45 a.m. IST the BSE Sensex was down 624.10 points, hovering at 77,527.35 – a 0.80 % dip that took investors back to the lows of early June. The NSE’s Nifty 50 wasn’t far behind, slipping 164.35 points to 24,169.95, a 0.68 % slide. It wasn’t just a headline number; the fall was driven by a cluster of heavyweights in the banking sector. Axis Bank saw its shares tumble more than five percent, HDFC Bank slid around 4.5 %, and Kotak Mahindra shed roughly three percent. The drag from these lenders helped set the tone for the broader market, with names like IndiGo, Maruti Suzuki and Bajaj Finance also posting losses.

It wasn’t all gloom, though. A handful of stocks managed to eke out modest gains – Trent edged up two percent, state‑run ONGC added about 1.5 %, and the likes of NTPC, Bharti Airtel and Tech Mahindra managed to stay in the green. Still, the overall sentiment was decidedly bearish, with the MSCI Asia‑Pacific ex‑Japan index slipping 0.3 % and South Korea’s KOSPI tumbling more than four percent after a holiday‑induced pause.

China, oddly enough, offered a brief reprieve. Its blue‑chip index rallied roughly 1.4 %, buoyed by expectations of continued stimulus and a softer yuan. Japan, meanwhile, was closed for a national holiday – a quiet footnote after a week that saw the Nikkei fall 6.4 %.

Beyond the obvious oil‑driven volatility, markets are also wrestling with a lingering inflation narrative. Futures pricing suggest roughly 29 basis points of additional Federal Reserve tightening could be baked in by year‑end, and there’s about a 60 % chance analysts see a rate hike as early as September. The 30‑year Treasury yield nudged back above the 5 % threshold, reinforcing the notion that higher‑for‑longer rates are now the default backdrop.

Tech‑heavy semis weren’t immune either. The Philadelphia Semiconductor Index, which had surged to a June peak, is now staring at a roughly 20 % drop from that high and is down about 10 % on the week. The broader U.S. market echoed the pain, with the S&P 500 slipping 1 % and the Nasdaq 100 down 1.4 % on the previous Friday.

Still, not every voice in the room is doom‑laden. Savita Subramanian, a strategist at Bank of America, reminded investors that “the underlying earnings momentum in Indian banks remains resilient,” and she believes the current dip could present a buying opportunity for those with a longer horizon.

All told, the day underscores how quickly a flashpoint in the Gulf can reverberate through oil, currencies, bonds and equities alike. Whether the markets will find a floor soon or keep wobbling in this volatile mix of geopolitics and monetary tightening remains to be seen.
