The Bank of England raised its benchmark interest rate to the highest level since 2009 in what may be its final blow against inflation before the U.K. leaves the European Union.

Governor Mark Carney played down concerns that Brexit may be disorderly and said mounting price pressures warranted Thursday’s quarter-point increase to 0.75 per cent. At the same time, he gave no indication that policy makers see a need to accelerate the path of rate hikes. The pound slid.

BOE policy makers are trying to strike a balance between taming inflation as the economy runs out of slack, and protecting against the risk that the nation’s Brexit talks will end in a hard rupture that hits growth. Carney himself noted that the negotiations are entering a “critical period” and that the BOE is prepared for all scenarios.

 “It’s very unlikely that the conditions over the next six to eight months will warrant another move in monetary policy,” said Dean Turner, U.K. economist at UBS Wealth Management. “If anything, the news flow on Brexit could get more feisty in the short term so this probably is it for the time being.”

The BOE’s reading of market rates now signals that another 25-basis-point increase isn’t likely until the first quarter of 2020, compared the third quarter of 2019 seen in the previous round of forecasts.

The pound slid as much as 0.9 per cent and was down 0.5 per cent at US$1.3063 as of 2:55 p.m. London time.

Most economists surveyed by Bloomberg had predicted Thursday’s rate hike, though the unanimous 9-0 vote came as a surprise. At least some dissent was expected after Jon Cunliffe, who oversees financial stability, called for caution in tightening policy.

Carney, who had argued that a slump in growth in the first quarter would prove temporary, said it would be wrong to be put too much emphasis on unknowns.

“We can’t be handicapped or tied by the range of Brexit possibilities,” he said. “The mistake is to always wait wait wait until you have perfect certainty.”

The BOE decision came a day after the U.S. Federal Reserve reiterated that it will slowly raising borrowing costs, and a week after the European Central Bank kept to its plan to end its bond-buying program this year. The Czech central bank raised interest rates on Thursday for the fifth time in a year. At the same time, the Bank of Japan has strengthened its commitment to an ultra-loose policy.

In the Inflation Report accompanying the decision, the BOE kept its economic-growth predictions for Britain broadly unchanged. The U.K. expansion is expected to be just 1.4 per cent this year, though it’ll average about 1.75 per cent a year through 2020, slightly above the 1.5 per cent long-term potential.

The forecasts see inflation slipping to 2.2 per cent in 2019 from an average of 2.3 per cent this year before settling at the goal in 2020.

The central bank said that if the economy grows as expected, “an ongoing tightening of monetary policy over the forecast period would be appropriate” but Carney repeated its phrase that rate hikes will be limited and gradual.

“I agree with markets,” said Samuel Tombs, an economist at Capital Economics Ltd. “They’ll fit one more in before he leaves, probably in May next year, at which point we should have some clarity over Brexit. In the meantime, I think the MPC will be very cautious.”
