Bank of England's timid rate rises risk inflation until 2030, Niesr warns

UK inflation will stay above the Bank of England's 2% target until at least 2030 unless the central bank acts more aggressively, the National Institute of Economic and Social Research (Niesr) has warned.

The thinktank's verdict lands one week after the Bank's monetary policy committee raised borrowing costs from 3.75% to 4% — a move Niesr calls too timid to stop inflation becoming a persistent feature of the UK economy.

UK inflation currently stands at 3.5%, driven higher by soaring fuel costs. Oil and gas prices have climbed sharply since the end of February, when the US and Israel launched their war on Iran.

Why does one quarter-point rise fall short?

Niesr director David Aikman said all the ingredients are in place for workers to demand inflation-linked salary rises. He urged the Bank to move faster.

"Inflation is set to rise above 4% in the new year, just as most pay awards for 2027 are being agreed, so the risk that it becomes embedded is rising," Aikman said.

"One further quarter-point rise is unlikely to be enough, and the longer the MPC waits, the more it will eventually need to do."

The MPC hinted at another increase after last week's move. Niesr's math says that pace won't cut it. Every month of delay, Aikman argues, forces a bigger correction later.

Takeaway: the thinktank sees a wage-price spiral forming, and it wants the Bank to break it now, not nudge at it.

What is oil doing to the numbers?

Brent crude has persistently traded above $100 a barrel in recent weeks, versus roughly $70 before the war. On Tuesday it dipped below $90 at one point — the lowest since 31 August — after Donald Trump downplayed the need for military action against Iran "at this point."

That relief didn't last. Investors reined in their enthusiasm after US inflation climbed 0.4 percentage points from September to October, showing high oil and gas prices still pushing up costs. The S&P 500 fell 0.9% by early afternoon on Wall Street.

Niesr based its UK and global growth forecasts on oil at $105 a barrel. Even with prices off their peak, the institute cautioned that continued difficulties in shipping and refining mean consumer prices will decline slowly.

Stephen Millard, an economist at the institute, said the lower oil price also hinges on Trump holding his new line. "We've seen him change his mind before," he said.

Takeaway: cheaper crude helps, but Niesr doesn't expect it to reach consumers quickly — or reliably.

How weak is UK growth?

Niesr expects the UK economy to grow 1.6% this year. For 2028, it forecasts just 0.9%, as high inflation, high interest rates and tight government spending erode consumer and business confidence.

The chancellor, John Healey, drew criticism for deferring difficult decisions in last month's budget. Niesr said repeating that pattern next year — as it has been repeated over the last decade — would leave a £30bn hole in government finances.

Aikman said markets would punish the Treasury by charging the UK more to borrow if government spending soared in areas such as defence without savings elsewhere.

He described a "double whammy" from higher energy prices and rising global borrowing costs that policymakers aren't addressing.

"Those pressures reflect global developments and cannot be avoided," he said. "How monetary and fiscal policy respond to them is a domestic choice, and on both fronts decisions are being deferred."

Takeaway: Niesr's charge is blunt — the UK can't control global oil or global rates, but it is choosing to delay its own response to both.

The stakes compound from here. With inflation set to breach 4% as 2027 pay talks conclude, Niesr's warning amounts to this: pay now with firmer rate rises and a tougher budget, or pay later — through 2030 — with entrenched inflation and pricier government debt.
