Gilt traders have significantly increased their hedging against UK government debt, indicating heightened anxiety regarding the Makerfield by-election results and the broader political landscape. The focus is on potential Conservative gains in a traditionally safe Labour seat. A poor showing for Labour could intensify leadership challenges for Prime Minister Keir Starmer, potentially paving the way for Andy Burnham to contest the top job. This political uncertainty is a primary driver of volatility in the UK's financial markets.
Bond investors, including major players like BNP Paribas Asset Management, Neuberger Berman, and Allspring Global Investments, are predicting that the outcome of this by-election could spark another period of instability in the UK's $3 trillion debt market. The concern stems from the possibility of Burnham, currently Mayor of Greater Manchester, attempting to challenge Starmer. While Burnham has previously walked back comments appearing to dismiss the importance of bond markets, little is known about his specific fiscal plans should he become Prime Minister, creating apprehension among investors.
Analysts from firms such as Ebury, a financial services company, suggest that markets might be underestimating the potential impact of a Burnham victory. Ebury's head of market strategy labels the risk posed by a Burnham win as "very high," anticipating a "most significant leftward shift" in policy. This could lead to a rapid repricing of UK fiscal risk. Investors in UK sovereign debt, or gilts, have generally favored Starmer and his Chancellor Rachel Reeves due to their commitment to fiscal discipline. Concerns about a potential shift towards looser fiscal rules under a new leadership are driving the increased risk premium on UK government bonds.
Indeed, some analysts contend that a Burnham win could be positive for market confidence, as he is a popular figure. However, a significant number of market participants, including Schonfeld's Colin Lancaster, are forecasting a possible yield spike if Burnham emerges victorious, indicating a belief that his premiership could lead to higher public spending and increased government debt. The volatility in gilt markets is expected to persist as the Labour Party navigates potential leadership changes, with various potential challengers to Starmer's position, including Wes Streeting and Ed Miliband, who are seen as more centrist and less likely to dramatically alter current fiscal policies.
