QatarEnergy, the Gulf state's national energy company, announced Tuesday it would suspend LNG deliveries to South Korea, China, Italy and Belgium, citing severe damage to production facilities at the Ras Laffan industrial complex from Iranian missile strikes on March 18 and 19.
The company's CEO Saad al-Kaabi said about 17 percent of Qatar's LNG export capacity had been knocked out, with repairs expected to take three to five years.
The force majeure strikes at a critical artery of the South Korean economy, while rippling across Asia's tightly linked gas market.
Natural gas accounted for about 20 percent of the country's primary energy consumption in 2024, roughly 56 million to 61 million metric tons of oil equivalent. Gas-fired plants generated about 26 percent of the nation's electricity last year, burning an average of 69,000 tons of LNG per day for power generation alone.
Matching its needs, South Korea is the world's third-largest LNG importer behind China and Japan, bringing in about 46.7 million tons in 2025.
While the Qatari share is far from dominant, the knock-on effects of its withdrawal threaten to reshape the entire global supply landscape.
Ras Laffan handles about 20 percent of the world's total LNG supply, and spot prices in Northeast Asia have already surged roughly 88 percent in under a month, climbing from $10.73 per million British thermal units in late February to $20.18 by mid-March.
"This is no longer a matter of spot price spikes. The structural premise that long-term Middle Eastern contracts offer the cheapest and most reliable gas has been shaken at its foundation," said Lee Dong-wook, an analyst at IBK Securities.
"What we are witnessing is a signal that Asia's entire gas procurement framework may need to be redrawn."
With markets rattled and winter stockpiling season approaching, Seoul has moved swiftly.
President Lee Jae Myung ordered a government-wide emergency response at a cabinet meeting on Tuesday. "The escalation and prolongation of the Middle East war are intensifying supply instability in crude oil and natural gas," Lee said, adding that "a preemptive emergency response system must be activated at the government level."
The Ministry of Climate, Energy and Environment rolled out a sweeping energy conservation plan the same day.
The government's most aggressive move targets the power mix itself. Five nuclear reactors currently undergoing maintenance will be brought back online by May to lift the national utilization rate from 73 percent to above 80 percent.
Coal-fired power plants will also be given greater latitude, with seasonal fine dust restrictions that cap output at 80 percent set to be eased on days when air quality permits. The government is further considering extending the lifespan of three coal plants slated for decommissioning this year.
The Gulf-triggered LNG crunch is expected to leave a deeper carbon footprint across Asia, as countries are forced to fall back on fossil fuels to replace natural gas.
In South Asia, Bangladesh is increasing coal-fired generation and imports, while Pakistan is leaning more heavily on domestic energy sources to avoid a repeat of LNG-driven power shortages seen during past supply shocks.
Across Southeast Asia, the Philippines and Thailand are boosting coal-fired output, while Vietnam is negotiating additional coal supply to offset reduced LNG usage.
Like Korea, Japan's major utilities are maintaining high coal utilization rates and ramping up nuclear output. Korea's ministry projects the recalibrated energy mix would cut daily LNG consumption in the power sector by up to 20 percent.
The Gulf crisis has also accelerated Korea's push to wean itself off Middle Eastern fuel.
It is expected to lend fresh momentum to the $44 billion Alaska LNG project, which Washington has been pitching to Seoul and Tokyo as a geopolitically secure alternative to Gulf supplies.
POSCO International has already taken a stake in Glenfarne Alaska Partners, the project's lead developer, and U.S. Energy Secretary Chris Wright has said he is in discussions with Korean and Japanese firms over participation.
Broader U.S. LNG imports are also gaining appeal. South Korea has steadily raised its American share to about 9.4 percent of total purchases, and a deal struck last year commits Korea Gas Corp. to an additional 3.3 million tons per year from U.S. terminals.
But since new supply projects will take years to bear fruit, Seoul must navigate the immediate shortfall with the tools at hand.
"Even if the Alaska LNG project is a full go, it will be at least 2040 before any results materialize. The Qatar cut will likely push Korea to seek extra supply from other contractors, including Canada and the United States," said Kim Seon-yong, a gas policy researcher at the Korea Energy Economics Institute.
Kim noted that unlike crude oil, LNG is difficult to store for extended periods — but added that the timing offers a narrow window of relief, as peak winter demand is still months away.
"The government can diversify its energy portfolio to cope with certain shortages from the Middle East conflict, but every energy source has an irreplaceable purpose," Kim said.
"If geopolitical difficulties prevent Korea from stacking a full load by October, we may have to resort to expensive spot LNG options."
