South Korea Restricts Government Fuel Use While Hormuz Crisis Threatens Military and Market Stability

TLDR:

• South Korea limits government vehicles to six operating days weekly amid worsening Middle East oil supply disruptions.
• The KOSPI fell 4.9 percent Monday as the won weakened and inflation accelerated under growing fuel pressure.
• Six countries across three continents now ration fuel, marking a shift from developing to advanced economies.
• U.S. troops stationed in South Korea rely on the same disrupted Middle Eastern supply chain facing civilian restrictions.

South Korea has announced mandatory fuel rationing, restricting government vehicles from operating one day per week on a rotating license plate schedule.

The move places the world’s 10th largest economy alongside developing nations that have already imposed similar measures.

As the Strait of Hormuz remains closed, energy supply chains face mounting pressure across multiple continents.

Rationing Spreads Beyond Developing Economies

South Korea imports between 73 and 87 percent of its oil from the Middle East. Every barrel travels through the Strait of Hormuz before reaching Korean shores. With the strait closed and mined, no alternative route exists for crude imports at scale.

The KOSPI index dropped 4.9 percent on Monday before a social media post from former U.S. President Donald Trump temporarily eased market fears.

The South Korean won has also been weakening steadily. Inflation is accelerating alongside these currency pressures.

Analyst Shanaka Anslem Perera noted on social media that the rationing is “no longer a developing-world phenomenon” and is “migrating up the GDP ladder.”

Countries that have already implemented restrictions include Sri Lanka, Bangladesh, Pakistan, India, and Slovenia. Slovenia was the first EU member to introduce QR codes and odd-even plate systems.

South Korea joins that list as a G20 member and home to global semiconductor manufacturers Samsung and SK Hynix.

The country fabricates roughly a quarter of the world’s memory chips. That output now operates under the same energy strain affecting far smaller economies.

Military Readiness and Regional Stability Face Pressure

South Korea hosts 28,500 American troops across several U.S. Forces Korea bases. These operations require continuous supplies of diesel, aviation fuel, and generator capacity. Joint military exercises between U.S. and South Korean forces consume thousands of tonnes of fuel annually.

That fuel supply traces back to the same Middle Eastern supply chain now under civilian restriction. If civilian vehicles face rationing, military logistics are under comparable pressure. Reduced military logistics capacity could affect deterrence posture against North Korea along the DMZ.

Taiwan is also watching developments closely. TSMC fabrication plants in Hsinchu are reportedly counting liquefied natural gas reserves in single-digit days.

Taiwan imports nearly all of its energy, and its timeline may be shorter than South Korea’s given smaller strategic reserves.

The broader picture connects a closed maritime chokepoint to semiconductor output, military readiness, and currency stability across three continents. Sri Lanka, Bangladesh, Pakistan, India, Slovenia, and now South Korea have all imposed rationing measures.

One strait is driving policy decisions in six countries simultaneously. As Perera put it, “The molecules do not check GDP rankings. The molecules check whether the chokepoint is open.”
