South Korea Tells Citizens to Take Shorter Showers

South Korea — the world's 10th largest economy — just told 52 million citizens to take shorter showers, only run the washing machine on weekends, and avoid charging their phones at night. Starting today, government cars with licence plates ending in 1 or 6 can't drive on Mondays. The reason: 70% of South Korea's oil used to flow through the Strait of Hormuz. That traffic has nearly stopped.

The country has roughly 68 days of oil reserves left. Analysts say it could be less than two months.

The 12-step plan for an advanced economy

President Lee Jae Myung announced the campaign at a cabinet meeting on Tuesday, invoking the spirit of 1997 — when 3.5 million Koreans donated wedding rings, gold necklaces, and family heirlooms to help repay an IMF bailout. That campaign raised 227 tons of gold. This time, the president isn't asking for jewellery. He's asking people to ride bicycles for short trips and vacuum only on weekends.

The 12-step energy conservation drive reads like wartime instructions dressed in government-speak. Charge electric vehicles during the day, not at night. Use public transport. Switch to energy-efficient lighting. Offices should turn lights off during lunch. Take the stairs, not the elevator.

For now, private vehicle restrictions are voluntary. The mandatory rules only cover government and public-sector cars, split into five groups by the last digit of their licence plate — each group banned from driving one day per week. But the government made clear: if the crisis deepens to Level 3 on the four-tier national resource security alert (it's currently at Level 2), private cars will face the same rules.

Electric and hydrogen vehicles are exempt. That detail alone tells you where Korea's energy future is heading.

The maths behind the panic

South Korea imports every drop of its oil and gas. Until the war started, roughly 70% of its crude came through Hormuz — one of the highest dependency rates of any major economy. Now the strait is functionally closed.

The government already released a record 22.46 million barrels from strategic reserves on March 11. That sounds like a lot. It covers eight to nine days of the country's 2.9-million-barrel daily consumption. The remaining stockpile — about 190 million barrels between government and private reserves — has analysts at the Korea National Oil Corporation calculating roughly 68 days of coverage.

Seoul imposed fuel price caps on March 13 — the first time in 30 years. It's rushing to restart five nuclear reactors currently under maintenance, aiming to bring the operational fleet from 16 to at least 19 by end of March. It lifted a coal generation cap it had kept for climate reasons. And it pledged a supplementary budget of 25 trillion won ($16.5 billion), including cash vouchers for every household.

The coverage gap

Korean media is treating this as the defining domestic crisis of the year. The Chosun Ilbo ran front-page analysis of reserve depletion timelines. Seoul Economic Daily tracked the strategic reserves being shipped overseas. TV networks covered President Lee's 1997 comparison in emotional detail.

Western outlets gave it a feature story. The NYT headline: "Take Shorter Showers." Reuters filed 600 words. Both framed it as a vignette — a colourful illustration of the war's reach. Neither explored the industrial consequences for a country that manufactures a quarter of the world's memory chips and builds one in three of the world's ships.

For 5.4 billion people across the Middle East, South Asia, Latin America, and Africa, the story doesn't exist at all.

What it actually means

South Korea isn't asking people to shower faster because it's a quirky policy experiment. It's doing it because 68 days is all the time a $1.7 trillion economy has left before the fuel runs out. The country that donated gold to save itself in 1997 is now being asked to donate shower minutes.

The question isn't whether South Korea can conserve enough energy. It's what happens to the global semiconductor and shipbuilding supply chains if it can't.
