What are gilts? How UK government bonds work and why the pound watches them

Gilts are bonds issued by the UK government to borrow money. Investors lend the government cash, receive regular interest, and get their money back on a set date. They are issued by the UK Debt Management Office on behalf of HM Treasury.

Two main types

  1. Conventional gilts pay a fixed rate of interest, called the coupon, twice a year.
  2. Index-linked gilts adjust their payments in line with inflation.

Prices and yields

Gilts are traded after they are issued. When their price falls, the yield, or return a new buyer gets, rises, and the other way round. Yields reflect what markets expect for interest rates, inflation and government borrowing.

Why the pound reacts

Higher gilt yields can attract foreign money and support the pound. But when yields jump because investors are worried about government borrowing, as in the UK in autumn 2022, the pound can fall at the same time.
