Bank of England policymaker Catherine Mann has issued a stark warning: UK inflation risks getting "embedded" in the economy, with prices potentially climbing back to around 4% just as many companies set their annual pay rises. Speaking at a TS Lombard-hosted event on Tuesday, Mann said the window for keeping price growth under control is narrowing, and the timing could hardly be more delicate.
Mann, who joined the Bank's Monetary Policy Committee (MPC) in 2021, noted that inflation has remained above the Bank's 2% target for her entire tenure. The danger, she argued, is that workers and employers begin to treat higher price growth as normal. Once that happens, inflation becomes much harder to dislodge, because expectations feed directly into wage demands and pricing decisions.
Why wage negotiations matter so much
The crux of Mann's concern is the annual pay cycle. Early in the year, many UK firms set pay rises for the next 12 months. If inflation is still running hot at that point, those wage deals could lock in higher labor costs for a full year. That matters most in services industries like hospitality, health care, and transport, where wages are a large share of total costs. Higher pay bills tend to push up the prices these businesses charge, which in turn feeds back into workers' demands for even bigger raises—a classic wage-price spiral.
Mann has been one of the more hawkish voices on the MPC, consistently voting for quarter-point rate hikes in July and September. She argued that the Bank previously signaled too much comfort with waiting, implying that delaying action could allow inflation to become entrenched. Her latest comments reinforce that stance, even as the broader economy shows signs of weakness.
What this means for rate expectations
For investors, Mann's 4% warning puts wage data firmly in the driver's seat for the Bank's November meeting. Markets are already pricing in a possible rate move, but her message suggests that the path of rates will depend heavily on upcoming wage and productivity figures. If pay growth stays strong, the Bank may need to keep borrowing costs higher for longer, even if the economy isn't booming.
That sensitivity typically shows up first in short-dated UK rate markets, such as SONIA futures and 2-year gilts. From there, it filters into interest-rate-sensitive borrowing costs, including the fixed-rate mortgage offers that banks set as their own funding costs reset. For everyday investors, that means mortgage rates and savings rates could stay elevated if inflation proves sticky.
Mann also highlighted productivity—how much output workers produce per hour—as a key variable. If productivity improves, firms can absorb higher wages without raising prices as much. But if productivity stagnates, the burden of higher labor costs falls on consumers through higher prices, keeping inflation alive.
What to watch next
Investors will be watching upcoming UK wage data and the Bank's November meeting closely. Any sign that pay growth is cooling could ease pressure on the MPC to hike again. Conversely, a hot wage print would reinforce Mann's warning and could push rate expectations higher.
Mann's comments come amid a broader global picture of sticky inflation. Central banks elsewhere are also grappling with whether price pressures are truly easing. For instance, Czech inflation has accelerated, keeping a rate hike on the table, while Thailand's inflation rose but remains within its target. Even in the US, services surveys point to hotter prices, suggesting the fight against inflation is far from over.
For UK investors, the takeaway is that inflation is not yet defeated. Mann's warning underscores the risk that price growth could settle at a higher level than the Bank's target, which would have lasting implications for interest rates, bond yields, and borrowing costs. While no one can predict the exact path, the message is clear: wage negotiations and productivity will be the battleground for inflation in the months ahead.
