Core Data & Capital Inflows:
- The New Demand: Official institutions, including global central banks, sovereign wealth funds, and government departments, are displaying meaningful buy-side interest in the UK government bond (gilt) market—many for the first time.
- The Yield Catalyst: This institutional pivot is driven directly by surging yields making UK debt look like “very good value.” Driven by the energy shock of the ongoing U.S.-Iran war, 10-year gilt yields skyrocketed 60 basis points (briefly topping 5.10% in mid-May), marking the steepest yield climb among advanced economies.
- The Sterling Weight: British sterling currently commands roughly 4.4% of total global currency reserves, according to the International Monetary Fund (IMF). Foreign central banks are now actively reviewing whether to increase this allocation.
Macro & Political Drivers:
- The Non-Asian Push: NatWest Markets CEO Jonathan Peberdy confirmed that the capital checking into the gilt market originates from outside of Asia, noting that these official bodies traditionally hold very small sterling portfolios.
- Domestic Headwinds: The bond selloff and widening yields have been heavily amplified by UK domestic political turbulence. The market is aggressively pricing in heightened fiscal risk stemming from severe local election setbacks for the Labour party and mounting cabinet pressure regarding the leadership future of Prime Minister Keir Starmer.
