PREVIEW Bank of England readies what may be its final rate hike

A general view of the Bank of England (BoE) building, the BoE confirmed to raise interest rates to 1.75%, in London, Britain, August 4, 2022.

LONDON, Sept 17 (Reuters) - The Bank of England is likely to hike interest rates once again this week, possibly the last hurrah for one of the great tightening cycles of the last 100 years as a cooling economy begins to worry policymakers.

All but one of 65 economists polled by Reuters in recent days predicted the BoE will raise Bank Rate to 5.5% on Thursday from 5.25%, which would mark its highest level since 2007.

Financial markets are less certain than economists - with rate futures on Friday showing a 25% chance of a pause - but both are coming to the view that the streak of rises in borrowing costs since December 2021 is in its last days.

If Bank Rate does peak at 5.5% - from a starting point of 0.1% - it would rank fourth on the list of Britains biggest tightening cycles of the last century, behind surges that took place in the late 1980s and in the early- and late-1970s.

Recession accompanied all of those prior sharp increases in rates - and a downturn is increasingly on the minds of the Monetary Policy Committee (MPC), with the 14 rate hikes it has already made yet to fully feed through into the real economy.

Much of the data over the last week underlined Governor Andrew Baileys comment this month that the BoE was “much nearer” to ending its tightening cycle.

Economic output in July dropped more steeply than expected, even if one-off factors like strikes were behind some of the fall, and the unemployment rate has already overshot the BoEs forecast for the third quarter as a whole.

The European Central Bank also cited a weak economic outlook when it hiked rates last week and signalled that would be its last such move in the current cycle.

But with inflation in Britain still running higher than in any other major advanced economy, the calculation for BoE officials is arguably more complex - with hot wage growth data in Britain still pointing to inflationary risks.

“While we expect the critical mass of the committee to be grouped around a 25 basis-point hike, the uncertain, finely balanced nature of the turning point in the cycle means we believe there will be dissenters on both sides,” said Jack Meaning, chief UK economist of Barclays.

Data between now and Thursdays announcement could yet change the debate.

Inflation figures for August due on Wednesday are likely to buck the falling trend thanks to rising petrol prices.

Investors will be wary of the BoEs tendency under Bailey to react strongly to above-forecast inflation prints - an approach that some economists say has undermined its ability to deliver a consistent message and control market rates.

As ever, the language employed by the MPC on the path ahead, and shifts the balance of opinion, could have a big market impact.

Benjamin Nabarro, chief UK economist at Citi, said a speech last week from the MPCs most hawkish member Catherine Mann - in which she warned against a pause for interest rates - might offer an early clue.

“Manns explicit pushback against a pause, and linked rebuke of majority MPC judgements is, we think a sign of an internal discussion that is moving against her. A pause therefore is, we think, part of the discussion.”
