Global markets rattle as Hormuz disruption drives oil above $115

Global oil prices surged and Asian stock markets fell sharply on Monday as the conflict involving the United States, Israel and Iran intensified, raising concerns over economic disruption and a broader regional escalation.

Brent crude climbed above $115 per barrel, up from around $72 on 27 February before the conflict deepened, amid a near-standstill of shipments through the Strait of Hormuz, a vital route for global energy supplies. The disruption follows Iranian threats against vessels passing through the waterway, fuelling volatility in global energy markets, says the BBC.

The impact has extended beyond the Middle East. In Australia, the states of Victoria and Tasmania introduced free public transport measures to help commuters cope with rising fuel costs.

Asian financial markets reacted strongly to the developments. Japan's Nikkei 225 fell more than 4.5% in early trading, while South Korea's Kospi dropped 3.5%, reflecting investor concerns over the economic fallout from the conflict. Analysts have also warned that the United Kingdom could face the most significant hit to economic growth among major economies as a direct consequence of the war.

The conflict has widened geographically, with Iran-backed Houthi forces in Yemen launching strikes against Israel, underscoring the growing involvement of regional proxies.

Tensions have also escalated through direct threats and military positioning. Tehran has warned it could target the homes and universities of US and Israeli officials. Meanwhile, an additional 3,500 US troops have arrived in the Middle East, prompting Iran's parliament speaker to say their forces are "waiting for American soldiers" and that they are "waiting" as US forces deploy to the region.

Attacks on infrastructure have added to concerns about further disruption. Iranian strikes have hit major industrial sites, including aluminium plants in the United Arab Emirates and Bahrain, causing injuries. Separately, a US radar jet stationed at a base in Saudi Arabia was recently photographed with significant damage.

The conflict, now in its fourth week, has raised questions about Washington's strategy. "Trump is waging war based on instinct and it isn't working," Jeremy Bowen, the BBC's international editor, said in an analysis one month after the conflict began.

While US troop deployments to the region have increased, officials have not confirmed whether they will be used for ground combat, a move that would mark a significant escalation.
