The number arrived on Thursday like a verdict. Brent crude closed above $119 per barrel. West Texas Intermediate exceeded $96. Bond yields jumped. European stocks tumbled for a second consecutive week. And in Frankfurt and London, the conversation that central bankers had been carefully avoiding became unavoidable: this war is no longer a temporary disruption to be waited out. It is a structural repricing of the global energy market, and monetary policy must respond.

As this paper reported, Europe's second energy panic in four years was already reshaping the continent's economic outlook. And the broader repricing was evident when markets began treating the war as an inflation problem, not merely a geopolitical one. What changed on March 20 is that central banks stopped pretending they could look through it.

The ECB Holds — and the Market Prices Hikes Anyway

The European Central Bank held its benchmark rate at 2.0 percent on Thursday. That was expected. What was not expected, six weeks ago, was what the bond market did next: it priced in two rate hikes for 2026. [1]

Six weeks ago, markets were pricing ECB rate cuts. The easing cycle that Christine Lagarde had carefully guided since late 2024 was supposed to continue. Inflation was falling. Growth was tepid. The path forward was lower rates, more accommodation, a gradual return to the pre-pandemic playbook.

The Iran war ended that path. European TTF natural gas surged 24 percent in the week ending March 19, hitting 61 euros per megawatt hour. [2] EU gas storage, which had been above 40 percent heading into March, is now being drawn down at a rate that makes next winter's supply a genuine concern. And Brent crude — the benchmark that prices energy for most of the world outside the United States — has risen roughly 60 percent since the war began on February 28. [3]

The ECB's statement on Thursday acknowledged "elevated energy prices" and "upside risks to inflation." That is central bank language for: the plan has changed.

The Bank of England's Dilemma

In London, the situation is arguably worse. The Bank of England was already contending with sticky services inflation and a housing market sensitive to rate expectations. Now it faces an energy shock on top of both.

Major brokerages — including those tracked by Reuters in its March 20 markets roundup — now see a greater probability of rate hikes from the BoE than at any point since mid-2023. [4] The logic is mechanical: energy prices feed into headline inflation, headline inflation feeds into wage expectations, wage expectations feed into services prices. The BoE's mandate does not permit it to ignore a 60 percent surge in crude.

Governor Andrew Bailey has said nothing publicly about the war's impact on rate paths. That silence is itself a signal. The BoE's next rate decision is April 3. By then, Brent may be higher still.

The Strait That Sets the Price

The immediate cause of the price surge is the Strait of Hormuz. Roughly one-fifth of the world's crude oil and liquified natural gas transits the narrow waterway between Iran and the Arabian Peninsula. Iran has effectively closed it with mines, small boats, drones, and anti-ship cruise missiles. [4]

Efforts to reopen the strait have so far failed. Trump told reporters on Friday that reopening it was "a simple military manoeuvre" that requires "a lot of help." NATO allies have declined to send warships. The president called them "cowards." [4]

Bob McNally, a former White House energy adviser now at Rapidan Energy Group, told CBC News that Iran has "grabbed a hold of nothing less than the world's jugular" and that clearing the strait could take weeks. Farzin Nadimi, an Iran military specialist at the Washington Institute, said Iran retains "large stockpiles of mines, mobile cruise missiles and hundreds of undamaged boats hidden along the coastline." [4]

RTE reported Friday that oil prices rose despite diplomatic efforts to open the strait, noting that the disruption extends beyond crude to include LNG shipments critical for European gas supply. [5]

The Inflation Arithmetic

The numbers are not abstract. A sustained Brent price above $110 adds approximately 0.8 to 1.2 percentage points to eurozone headline inflation over a six-month horizon, depending on pass-through assumptions. For the UK, the figure is closer to 1.0 to 1.5 points, reflecting greater direct exposure to global energy prices.

That arithmetic transforms the rate outlook. If the ECB was expecting inflation to settle near its 2 percent target by late 2026, an additional percentage point from energy costs pushes the timeline into 2027 — or forces the central bank to hike rates to bring inflation down faster. Neither option is pleasant. Both are now on the table.

The same calculus applies in London, Stockholm, and Oslo. It applies, with different variables, in Tokyo and Ottawa. The war in Iran is not a regional conflict that monetary policymakers can observe from a distance. It is inside their models now.

What Markets Are Telling Us

On X, the financial accounts that set the tone for market sentiment have moved past the shock phase. The Kobeissi Letter's "Conflict Playbook" series has been tracking escalatory steps against market indicators since before the war began. Its latest assessment places the conflict between Step 6 and Step 7 of its framework — the zone where "energy prices become a macro constraint." [6]

Wind Info, a widely followed financial data account, posted the number that crystallizes the shift: "ECB held rates at 2% on Thursday. Bond markets are pricing two rate hikes this year. Brent crude pushed past $119 a barrel and WTI exceeded $96." [1]

That single post contains the entire story. The central bank held. The market moved anyway. The war set the price.

The Continental Perspective

European leaders are beginning to say publicly what their central bankers cannot. EU High Representative Kaja Kallas, speaking March 19 — the day Brent hit $119 — said the war "could reshape the economic landscape of Europe for years." European TTF gas and Brent crude were both at levels not seen since the worst months of the Russia-Ukraine energy crisis in 2022. [2]

The difference this time is that Europe has less cushion. Russian pipeline gas is largely gone. Storage levels are lower. Industrial demand, though weakened by recession, is not zero. And the diplomatic tools available to reopen supply — sanctions relief, transit agreements, emergency purchasing deals — are thinner than they were in 2022.

For central bankers in Frankfurt and London, the war has closed the door on the easing cycle that was supposed to define 2026. What opens in its place is an environment they have not faced in three years: rising energy costs, rising inflation expectations, and a policy rate that may need to go higher before it goes lower.

Brent at $119 is not a spike. It is a price. And the central banks are, finally, pricing it in.
