Catherine Mann cautions that the surge of overseas buyers in the UK gilt market could heighten susceptibility to sudden market swings, risking higher borrowing costs amid global shocks.
Bank of England rate-setter Catherine Mann has warned that the growing presence of overseas buyers in the UK gilt market could make government borrowing more exposed to sudden swings in sentiment.
Speaking in a speech at the London School of Economics on 13 May, Ms Mann said international investors now play a “particularly large role” in the purchase of UK Government debt. Her concern is that, while such buyers can help keep borrowing costs down when demand is strong, they can also pull back quickly if confidence weakens or shocks hit the economy.
The warning comes as long-dated UK borrowing costs have risen sharply in recent days. The yield on the 30-year gilt has climbed to near a 28-year high, briefly moving above 5.8% on Tuesday, while the 10-year benchmark has also edged higher. Because bond prices move in the opposite direction to yields, those rises imply falling gilt values and higher financing costs for the state.
Ms Mann argued that the market is now more vulnerable to volatility because of what she described as “new actors” in the buyer base. In her view, these investors tend to be more sensitive to domestic and global shocks, which means they may be quicker to sell if conditions deteriorate.
She said that if confidence were hit by a fresh shock, price-sensitive foreign holders could reduce their gilt exposure. That, she warned, could trigger further turbulence in financial conditions and leave the government facing a more expensive market for borrowing.
Ms Mann also suggested that tighter monetary policy could itself unsettle the market if those investors decide to unwind positions. In that scenario, she said, borrowing conditions at home could tighten by more than policymakers intended.
Her remarks reflect a broader concern about the changing structure of demand for UK debt, as the market becomes less dependent on traditional domestic institutions and more reliant on international capital flows.
