News of the week summary - 15/03/2026

Oil's most volatile week in decades, and an unprecedented IEA response

On Monday, the market's growing understanding of what the Strait of Hormuz closure meant for global supply produced the most extreme single-day move in crude futures in the history of the Brent contract. Prices surged more than 29 percent intraday, touching $119.50 per barrel at the peak, before profit-taking and scepticism about how long the disruption would persist pulled prices back sharply. Brent settled the day at $98.96, a gain of 7 percent but well below the intraday high. On Tuesday, prices fell more than 11 percent. By the end of the week, after a period of calmer but still elevated trading, Brent settled at $103.14 per barrel. Futures prices for the year-to-date were up 72 percent. The contract had crossed $100 per barrel for the first time in four years.

The violence of the price movements reflected two things simultaneously: the genuine severity of the supply disruption, and the uncertainty about how long it would last. Every positive signal about diplomacy sent prices down sharply; every signal about escalation or continued closure sent them up. Buyers could not be certain whether the Hormuz disruption would last weeks or months. Sellers of futures positions faced the same uncertainty in the opposite direction. That combination produced the kind of intraday volatility, in both directions, that is characteristic of a market operating without a reliable forecast of the future supply path.

The IEA's response on Wednesday added an unprecedented institutional dimension. All 32 member states of the International Energy Agency unanimously agreed to release 400 million barrels of oil from their strategic reserves, representing roughly four days of global consumption. It was the largest coordinated emergency reserve release in the IEA's 52-year history, exceeding the previous record set during the Russian invasion of Ukraine in 2022, when 60 million barrels were released in March and a further 120 million in April. The agency described the current disruption as the largest supply shock in the history of the global oil market and characterised it as the greatest energy security challenge the world had faced. Emergency reserve releases are designed to bridge a gap: they provide physical supply while markets reorganise, but they cannot substitute for the primary supply that has been interrupted. At 400 million barrels against a global consumption rate of roughly 100 million barrels per day, the release bought approximately four days of breathing room.

Qatar declares force majeure on all LNG exports

The most consequential development for markets outside crude oil this week came from Qatar, the world's second-largest exporter of liquefied natural gas. QatarEnergy declared force majeure on all of its LNG export contracts, citing the physical impossibility of loading and departing tankers from its terminals while the Strait of Hormuz remained effectively closed to commercial shipping. Qatar accounted for roughly 21 percent of global LNG trade in 2025, serving customers across Asia, Europe, and South Asia under long-term supply agreements. Those agreements were now suspended.

The declaration mattered disproportionately to Europe, which had spent the previous three years diversifying away from Russian pipeline gas and replacing it partly with Qatari LNG. European wholesale natural gas prices, which had already risen sharply in the week the conflict began, moved higher again. UK household energy price forecasts began to be revised upward. Asian LNG spot markets, where gas is bought without long-term contracts, saw prices rise to levels not seen since the winter of 2022-2023. Singapore and South Korea, both heavily dependent on Gulf LNG, began activating emergency protocols. The fertiliser market, which relies on natural gas as a primary feedstock, flagged the risk of significant production cuts at a moment when the Northern Hemisphere spring planting season was approaching.

The force majeure declaration illustrated how the energy shock extended well beyond crude oil. Oil gets the price and attention, but gas and LNG were embedded in the heating, cooking and industrial processes of dozens of countries in ways that did not have immediate substitutes. While oil could, in principle, be sourced from non-Gulf producers at higher prices, the LNG market was smaller, less flexible, and far more regionally constrained. The loss of Qatari supply was not something that additional US or Australian LNG production could quickly fill.

February CPI

On Wednesday, the Bureau of Labor Statistics published the Consumer Price Index for February, and it landed almost exactly where forecasters had expected. Headline CPI rose 0.3 percent in the month and 2.4 percent over the prior year, unchanged from January and matching consensus forecasts. Core CPI, excluding food and energy, rose 0.2 percent for the month and 2.5 percent annually, also in line with expectations. Shelter inflation decelerated sharply, with rents rising just 0.1 percent, the smallest monthly increase since January 2021. Food prices rose 0.4 percent, partly reflecting persistent supply chain pressures in beef and coffee that predated the conflict. Egg prices continued to fall, down 3.8 percent for the month.

The report was, almost immediately, widely described as a lagging indicator rather than useful intelligence. The BLS collects CPI data during the first two weeks of each month, meaning the February report captured prices from a period before the conflict began on February 28. Economists described it variously as "the calm before the storm" and "old news before it was released." The data confirmed what was already known: that inflation had been decelerating modestly in early 2026, that core services remained sticky, and that the Fed's progress toward its 2 percent target had been real but slow. What it could not show was the surge in gasoline prices that had already begun by the time the report was published, or the cascade of higher transport, freight and food costs that analysts expected to follow.

For the Federal Reserve, the February CPI was a baseline, not a forecast. The March reading, due in mid-April, would be the first to capture the war's impact in consumer prices. Analysts at the time were estimating that the March CPI could easily print above 3 percent year-on-year, depending on how quickly the March gasoline price surge fed into the index. A figure above 3 percent would be the highest reading in over two years, and would arrive just as the FOMC was attempting to decide whether to hold, cut, or eventually raise rates.

US existing home sales stabilise

Earlier in the week, the National Association of Realtors had published the existing home sales figure for February. Sales of previously owned homes rose 1.7 percent to a seasonally adjusted annualised rate of 4.09 million units, partially recovering from January's 8.4 percent decline, which had followed an unusually strong December. The trailing six-month average rate of 4.11 million units per year was the highest since April of the prior year, and the NAR's chief economist noted that declining mortgage rates over the preceding twelve months had gradually improved affordability.

The housing data mattered less for what it said about February and more for what it suggested about the baseline the US economy was operating from before the conflict began. A housing market that had been slowly reviving after years of elevated borrowing costs represented a source of consumer confidence and wealth that would now face a new set of pressures: higher petrol prices, rising concern about the economic outlook, and the likelihood that bond yields would move higher as inflation fears intensified. Whether the housing recovery would survive an energy shock of this scale was an open question that would take months to answer. For the week of March 15, the question had barely been asked.
