Power Markets under the 2026 Oil and Gas Price Shock
The 2026 Middle East war transmitted into electricity systems through oil and gas prices, not through a single global power price. When Dated Brent reached 144 United States dollars per barrel in early April, and when LNG supplies from Qatar and the United Arab Emirates fell by over 300 million cubic metres per day from 1 March, the cost of fuels that set or influence power prices rose sharply. This article explains the mechanisms that link those verified oil and gas shocks to electricity costs.
Regional power price figures are cited only where the IEA or Euronews publish them. The International Energy Agency records that the war began on 28 February and that flows through the Strait of Hormuz fell from around 20 million barrels per day prior to the conflict to an average of 2.7 million barrels per day in March, April and May. A substantial share of long term LNG and pipeline gas pricing remains indexed, in whole or in part, to oil benchmarks such as Dated Brent or related crude baskets.
In systems that still use diesel or fuel oil for peaking, backup or islands of the grid, middle distillate spikes feed directly into generation cost. The IEA Hormuz factsheet notes that natural gas dominates the power sectors of Bangladesh and Pakistan, with gas fired generation accounting for 50 per cent and 25 per cent of their electricity supply mixes respectively in 2024. When Asian spot LNG commanded a premium averaging 2.1 dollars per million British thermal units over TTF from March to June, flexible cargoes diverted from Europe to Asia.
How large was the oil side buffer that indirectly protected some power systems? Global oil inventories drew at 3.8 million barrels per day on average from the start of the conflict. Step one is to lock the fuel facts to primary pages: Dated Brent at 144 dollars, Hormuz oil flows at 2.7 million barrels per day on average in March to May, LNG losses above 300 million cubic metres per day from Qatar and the UAE since 1 March, TTF near 16 dollars and JKM at 17.5 dollars on second quarter averages.
Governments that still rely on oil linked LNG for a large share of power fuel should accelerate reviews of indexation and of storage. The mid June interim agreement between the United States and Iran, which aimed to reopen Hormuz, eased some price pressure. In plain terms, the 2026 oil and gas shock raised the cost of the fuels that many power systems burn at the margin, tightened LNG availability for gas dependent grids, and stressed diesel supply for peaking and backup.
