EUR/GBP breaks below 0.86 as ECB rate hike bets fade on oil drop

EUR/GBP slid below 0.86 for the first time in 2026 as investors priced out further ECB rate increases after oil prices tumbled on a US-Iran peace deal.

EUR/GBP broke below 0.86 for the first time this year, sliding to 0.8546 as markets abandoned bets on further ECB rate hikes after oil prices collapsed on a US-Iran peace deal.

"EUR/GBP delivered a sizeable downside breakout last week, which should be respected," said Francesco Pesole, FX strategist at ING. "Helping that move were stale sterling shorts and a view that if volatility was falling this summer, there was no point in paying away 2% per annum in carry by being short sterling."

The euro weakened 0.94% against sterling over the past week, the largest decline among major currencies, while the pound gained 1.32% against the dollar to trade at $1.3372. The single currency also slipped 0.36% versus the greenback to $1.1428. The pair had been locked in a 0.86-0.878 contracting range for the entirety of 2026 before breaking lower last week and swiftly testing 0.854.

The break below 0.86 signals a fundamental repricing of ECB policy expectations that could keep the euro under pressure through the summer. Markets now see almost no chance of a rate increase at the ECB's July meeting and have sharply reduced probabilities for September action. The next test for the pair will be the ECB's July 25 decision, where Lagarde's tone on the inflation outlook will determine whether 0.85 becomes the new floor or the next leg lower.

ECB Pivot Priced In After Oil Rout

The odds of further ECB tightening have collapsed since the bank delivered a 25-basis-point increase in June. The shift was triggered by the interim peace deal between the US and Iran, which sent oil prices sharply lower and eased fears of a prolonged inflation shock that had appeared more serious in May and early June. Headline inflation pressures from energy have moderated faster than many expected, giving policymakers room to pause.

Christine Lagarde addressed the repricing directly in late June, pushing back against the characterization of the June move as an insurance hike. "Some have characterized our rate increase earlier this month as an 'insurance hike.' That is not an accurate description," she said, stressing the data-dependent approach. Bundesbank President Joachim Nagel has also adopted a more measured tone, highlighting the need to watch incoming data on wages and second-round effects as the energy shock looks less persistent.

The euro area economy adds another layer of complexity. Growth projections were cut after the June meeting, pointing to weaker real incomes and confidence. Unemployment remains low at around 6.3%, but labor demand has cooled and firms are more cautious. Core inflation excluding food and energy is expected to average 2.5% this year and next before declining further, according to the ECB's latest staff projections — a path that gives policymakers room to pause after the June move rather than rush into another increase.

Sterling Gains on Multiple Fronts

The pound's strength reflects more than just euro weakness. GBP/USD climbed to $1.3372, its highest in two weeks, as a disappointing US jobs report prompted investors to scale back Federal Reserve rate hike expectations. JPMorgan has lifted its sterling forecasts for 2026, citing easing UK political uncertainty and resilient economic data. Lower mortgage rates could support UK growth, according to Pantheon Macroeconomics, reinforcing the view that the British economy continues to outperform expectations.

The combination of fading ECB hawkishness, falling energy prices, and improving UK fundamentals has created a powerful tailwind for sterling. For euro holders, the break below 0.86 raises the question of whether the pair can find support near 0.85 or whether the next leg lower targets the 2022 lows around 0.84.
