UK inflation surges to 5.1%, highest in decade, as BoE weighs rate decision

Britain's inflation problem arrived faster and hotter than anyone expected. In November, consumer prices climbed to 5.1 percent—the highest level in more than a decade, since September 2011. The jump caught forecasters off guard. Economists polled by Reuters had predicted a rise to 4.7 percent; instead, the Office for National Statistics reported something considerably worse. The culprits were everywhere: petrol stations, clothing racks, shoe shops. Energy and goods prices had conspired to push the cost of living upward across a broad swath of the economy.

The timing could hardly have been worse for the Bank of England. The central bank was set to announce its December policy decision the very next day, and this inflation reading landed like an unwelcome guest at the door. Just a month earlier, the BoE had predicted that inflation would crest around 5 percent in April 2022, when regulated household energy bills were scheduled to jump again. Now, in mid-December, that peak was already nearly in sight. The International Monetary Fund, watching from the sidelines, had grown more pessimistic still—it was forecasting British inflation would hit 5.5 percent, a 30-year high, sometime in the coming year. The IMF had also issued a pointed warning: the BoE should not fall prey to "inaction bias," the tendency to do nothing when action was needed.

Yet the central bank faced a genuine dilemma. Inflation had soared globally throughout 2021, driven by energy prices and the lingering wreckage of COVID-related supply-chain disruptions. Britain had its own particular burdens: post-Brexit trade and migration barriers had added friction to the economy. The BoE had already signaled that interest rates would almost certainly need to rise to combat these pressures. It had held off on a widely expected move in November, citing uncertainty about the impact of the government's decision to end its job furlough programme. Now, with inflation data this hot, the pressure to act was mounting.

But Omicron was spreading. Cases were rising rapidly, and many economists believed the new coronavirus variant posed enough of a threat to economic growth that the BoE might choose to hold steady on Thursday despite the inflation surprise. Chris Hare, an economist at HSBC, captured the tension: under normal circumstances, this inflation reading would point clearly toward a rate rise. But the Omicron headwinds suggested caution. "The decision is not a straightforward one by any means," he said. Samuel Tombs, chief economist at Pantheon Macroeconomics, offered a different perspective on the inflation trajectory itself. He thought prices could reach 6 percent by April but would then fall sharply, potentially undercutting the BoE's 2 percent target by 2023. In other words, the current spike might be a temporary phenomenon, not a structural shift.

Markets were already pricing in the uncertainty. On Wednesday, when the inflation data dropped, sterling rose modestly against the dollar and the euro. Two-year gilt yields hit a one-week high. Interest rate futures shifted: traders now saw a 63 percent chance of a rate rise on Thursday, up from below 50 percent the day before. They were also pricing in a faster pace of tightening across 2022. A move to 0.25 percent from the current 0.1 percent was already fully baked into expectations for February, which would make the BoE the first major central bank in the world to raise rates since the pandemic began.

The breadth of the price increases was striking. Core inflation, which strips out the most volatile items like energy and food, had climbed to 4.0 percent from 3.4 percent in October—its highest level since 1992. Fuel prices alone had surged 28.5 percent. The retail price index, an older measure used for government bonds and wage negotiations, had jumped to 7.1 percent from 6.0 percent, reaching its highest point since March 1991. These were not marginal moves. They were the kind of numbers that reshape household budgets and force policymakers to confront hard choices about growth versus stability.
