Sterling Faces Most Intense Attack Since Brexit as Traders Bet Against Pound

Speculators have initiated their most sustained assault on the British pound since the Brexit referendum, with official figures revealing a significant increase in bets against the currency. Net bets against sterling have recently reached their highest point in almost a decade, totaling over £6.5 billion, according to data from the U.S. Commodities and Futures Trading Commission.

This trend is being described as a "disastrous vote of no confidence in Labour" by Shadow Chancellor Andrew Griffith. He stated that traders are expressing their lack of confidence because they perceive the government's only recourse to balance its accounts as increased taxation and borrowing to fund higher public spending, particularly on welfare.

The pound's current position at $1.32 against the U.S. dollar marks its lowest level in nearly three months. This decline is partly attributed to the Bank of England's decision to maintain interest rates, unlike many other central banks, making sterling less attractive to investors.

Investor sentiment against the pound, which is often seen as a proxy for the health of the British economy, is now as negative as it was shortly before the 2022 mini-budget. That event, characterized by unfunded tax cuts under the Liz Truss administration, saw the pound's value plummet towards parity with the dollar.

Jane Foley, head of foreign exchange strategy at Rabobank, noted that speculators are expressing caution regarding the pound and are hesitant to hold long positions leading up to the upcoming budget. The continuous run of 'sell' orders against sterling is projected to be the longest since the UK's vote to leave the European Union in 2016.

While a weaker pound can benefit exporters, it also leads to increased import costs, potentially exacerbating inflation and limiting the possibility of interest rate reductions in the near future. The UK's reliance on foreign investment to fund its deficit means that a substantial portion of its national debt, about one-third, is held by international investors who may be more sensitive to negative economic news.

Prime Minister Andy Burnham has previously defended the stance that the UK should not be excessively indebted to bond markets. However, the rising interest costs on the UK's approximately £3 trillion national debt are constricting Chancellor John Healey's fiscal flexibility ahead of the budget. Experts suggest that the limited financial 'headroom' available to Healey has been significantly reduced by recent bond market volatility, making further tax increases to fund welfare and defense spending likely.

Chris Beauchamp, chief markets analyst at broker IG, commented that the government leadership might feel "claustrophobic" as borrowing figures continue to rise. Public sector borrowing alone reached £18.3 billion in August, exceeding expectations by £3 billion. Beauchamp highlighted that borrowing costs are increasing while the overall borrowing is outpacing the modest rise in tax receipts, and questioned the government's ability to implement necessary fiscal measures amidst party divisions.
