Key Financial Impacts of Strait of Hormuz Closure on Oil Markets

Nikolay Dudchenko
Iran conflict blocks Strait of Hormuz, cutting 7M bpd oil supply and surging Brent 40%+. US/Europe face stagflation; Russia eyes budget relief from higher duties.

The Strait of Hormuz remains effectively closed due to the ongoing Iran conflict, blocking nearly 20% of global oil and LNG flows and driving Brent crude up over 40-55% to above $100 per barrel. This supply shock has caused stockpiles to build in Saudi Arabia, Iraq, UAE, and Kuwait, forcing production cuts of about 7 million barrels per day—roughly 7% of world demand.

Key Consequences of Strait Restrictions

  • Higher gasoline prices in the US and Europe, fueling inflation without economic growth.
  • Stagflation in developed economies, with rising prices but stagnant GDP.
  • Fed meeting today unlikely to cut rates; Jerome Powell steps down in May, replaced by Trump’s appointee Kevin Warsh, clouding future policy.
  • Increased demand for alternatives like coal, whose prices have surged; fertilizer costs also rise due to disrupted shipments.

In the long term, global stagflation and economic slowdown will curb oil demand, eventually pushing prices down as supply normalizes.

Benefits for Russia

The situation offers short-term opportunities across external and domestic fronts.

External Track

A prolonged Iran conflict could make the US and Europe more amenable to negotiations, potentially hastening resolutions—though this depends on diplomatic progress.

Domestic Situation

Russia’s Finance Ministry reported a January-February budget deficit of 3.449 trillion rubles, hitting 90% of the full-year plan of 3.786 trillion, sparking sequestration talks to cut spending. Higher March oil export duties provide short-term relief. The Central Bank meets Friday and may cut rates by 50 basis points to 15%; budget cuts could accelerate easing. USD/RUB has risen to 81, while the MOEX Index climbed to 2870 points after breaking 2850—a medium-term trend signal—but gains rely heavily on oil, questioning sustainability.
