Episode notes
Global Forces Behind Gilt Sell-Off
- Global long-end yield moves, especially in the US, are driving UK 30-year gilt yields higher and not solely a UK fiscal crisis.
- Dealers hedging ahead of big syndicated sales and weak long-end demand amplify gilt sell-offs.
30-Year Yield Isn’t Full Fiscal Picture
- The DMO is issuing more short-dated debt, so 30-year yields are a poor single gauge of fiscal headroom.
- A rough back-of-envelope move in yields could cut Chancellor headroom from £10bn to about £2bn.
Build Credible Fiscal Headroom
- Chancellor should aim to rebuild credible fiscal headroom ahead of the budget to calm markets.
- Even signalling intent to move toward historic averages of headroom can improve market confidence.
