Why long-term illness is fueling wage inflation in the U.K. economy?

The UK economy is experiencing persistent wage inflation driven by a record 3 million workers sidelined by long-term illness, primarily mental health issues, creating a structural 'total worker shortage' despite rising unemployment, according to BCA Research. This labor market dysfunction forces the Bank of England into a difficult choice between risking recession to meet its inflation target or compromising price stability, while also increasing government benefit costs. Despite these challenges, BCA Research recommends overweighting GBP/USD and UK gilts, citing the BoE's anticipated political independence and the UK government's expected fiscal caution.

Analysis

The UK economy is facing a significant structural impediment to disinflation, as detailed in a BCA Research report. Persistent wage inflation is being driven by a constrained labor supply, with a record 3 million working-age individuals, or one in twenty, sidelined by long-term illness. This has created a scenario where, for the first time in nearly two decades, those inactive due to illness outnumber students. The issue is deeply entrenched, evidenced by a doubling in part-time workers citing illness over the past decade and a 20% post-pandemic surge in long-term sick leave among public sector workers, primarily due to mental health issues. Consequently, the UK's 'total worker shortage rate' remains 1% above pre-pandemic levels, negating the deflationary impact of falling job vacancies and rising unemployment. This places the Bank of England in a difficult position, as cooling wage growth to its 2% target would necessitate a further 1% drop in job vacancies, likely tipping the unemployment rate above 5.5% and triggering a recession. Despite this bleak domestic backdrop, BCA Research advocates for a structurally overweight position in GBP/USD and UK gilts relative to US Treasuries. This counter-intuitive recommendation is predicated on a relative value judgment, hypothesizing that the Bank of England will maintain greater political independence than the U.S. Federal Reserve and that the UK government will pursue a more fiscally cautious path than a potential Trump administration.

Key Decisions for Investors

• Investors should recognize that UK wage inflation is structurally persistent due to labor supply constraints from long-term sickness, complicating the Bank of England's path to its inflation target and elevating the risk of a policy-induced recession.
• Consider BCA Research's relative value thesis by potentially overweighting GBP/USD and UK gilts, a strategy that bets on the UK's institutional stability and fiscal prudence relative to the United States, rather than on a strong standalone UK economic outlook.
• Closely monitor UK labor market data, specifically long-term sickness rates, as any improvement or deterioration in this structural issue will be a key determinant for the future path of UK wage inflation, monetary policy, and the viability of long gilts and sterling positions.
