Foreign investors turned net sellers of UK government bonds in May, dumping £5.5 billion of gilts as political turmoil spooked overseas buyers. The selling snapped an eight-month buying streak and came after the ruling Labour Party suffered a severe defeat in local elections, triggering calls for Prime Minister Keir Starmer to resign. While yields have since eased following a US-Iran ceasefire deal, uncertainty persists with Andy Burnham expected to take over Labour and yet to name his choice of Chancellor.
The exodus highlights how fragile foreign demand for UK debt has become in an era of abundant global alternatives. Non-residents hold roughly a third of all gilts and can quickly shift capital elsewhere during crises, especially with hedge funds playing a growing and potentially destabilizing role. Officials have warned that leveraged trades could unwind violently if the bond market moves against expectations.
Domestic investors stepped in to absorb the selling, buying a net £19.1 billion of gilts in May, the most since August. This contrast underscores a divergence in confidence: local buyers see value, but overseas investors are voting with their feet. As Zurich Insurance's chief markets strategist put it, if investors lack faith in both the prime minister and the chancellor, they will simply leave.
What to watch next: Whether Andy Burnham's choice of Chancellor can restore credibility with foreign bondholders, and if gilt yields can stabilize without a sustained foreign buying spree.
Key Takeaways
- Foreign investors sold a net £5.5 billion of UK gilts in May, ending an eight-month buying streak.
- Political instability after Labour's local election rout and Starmer's resignation drove the selloff.
- Domestic buyers absorbed the selling, purchasing a record £19.1 billion in gilts during the same period.
- The UK's reliance on fickle foreign capital leaves the gilt market vulnerable to further political shocks.
Insights & Analysis
- The divergence between foreign and domestic buying behavior suggests a structural shift: overseas investors now demand a political stability premium that UK bonds may not offer.
- If hedge funds are forced to unwind leveraged gilt positions during the next crisis, the Bank of England may face pressure to intervene more aggressively than in past episodes.
