The recent military escalation involving the United States, Israel and Iran has unsettled global oil markets, with analysts warning of a potential sharp rise in crude prices if disruptions intensify.
Although Iran accounts for only about 3–4% of global oil output, its strategic position near the Strait of Hormuz — the world’s most critical oil chokepoint — has heightened concerns. Roughly one-fifth of global oil production passes through this narrow waterway.
A prolonged disruption could push oil prices above the $100-per-barrel mark, a scenario that would strain the global economy and complicate efforts to curb inflation.
Brent crude had already climbed to around $73 per barrel in late February amid fears of potential strikes in the oil-rich region. In response to mounting tensions, OPEC+ — led by Saudi Arabia and including Russia — announced an increase in production quotas starting in April in an effort to stabilise markets.
Iran’s Oil Production and Global Role
Iran produces approximately 3.3 million barrels per day (bpd), making it the fourth-largest producer within Organization of the Petroleum Exporting Countries (OPEC). It also holds about 12% of global oil reserves and nearly a quarter of Middle Eastern reserves, according to the U.S. Energy Information Administration (EIA).
Despite long-standing Western sanctions and underinvestment, Iran has managed to expand output in recent years, largely by exporting crude to China, which now purchases around 90% of Iran’s oil exports.
Why the Strait of Hormuz Matters
The Strait of Hormuz connects the Persian Gulf to the Gulf of Oman and the Arabian Sea. Major producers including Saudi Arabia, the United Arab Emirates, Kuwait and Iraq rely on it to transport crude to global markets.
Recent tensions have reportedly disrupted shipping activity, with several energy traders suspending shipments due to security concerns. If flows are severely constrained, up to 15 million bpd — roughly 30% of global seaborne crude trade — could be affected.
Energy consultancy Rystad Energy estimates that even partial disruption could remove 8–10 million bpd from the market, triggering a substantial price spike.
OPEC+ Response and Market Buffer
OPEC+ has opted to increase production beyond earlier expectations but stopped short of a dramatic supply surge. Analysts suggest the alliance is balancing short-term geopolitical risks against the possibility of oversupply later in the year.
Saudi Arabia has already boosted exports in recent weeks, potentially creating a short-term buffer. However, experts caution that such measures are limited in scope and cannot fully offset sustained supply disruptions.
Global Economic Impact
A sharp increase in oil prices would have wide-ranging consequences. Higher crude prices tend to drive up transportation and manufacturing costs, feeding into broader inflation.
Economists estimate that a 5% year-on-year rise in oil prices adds roughly 0.1 percentage points to inflation in major economies. If Brent crude climbs to $100 per barrel, global inflation could rise by 0.6–0.7 percentage points.
Higher inflation may dampen consumer spending and force central banks to maintain or raise interest rates, potentially slowing global economic growth.
As geopolitical tensions remain elevated, markets are closely watching developments in the Strait of Hormuz and any signals of de-escalation that could stabilise oil flows and prices.
