The UK Treasury Index-Linked 1.125% 2037 is a index-linked gilt with a 1.125% coupon, maturing on 22 Nov 2037 — roughly 11.1 years from now. At the latest market price it is a medium-dated (5–15 years) holding currently trading below par (at a discount).
Based on a clean price of about £90.04 per £100 nominal, this gilt offers a running yield of 1.25% and a real yield of 2.14% (about 5.15% a year if RPI inflation averages 3%). The running yield reflects the income return from coupons alone, while the real yield also accounts for the capital gain if you hold to redemption.
As an index-linked gilt, both its principal and coupon payments are uprated in line with inflation (RPI). The headline coupon is low because the inflation uplift is delivered separately — making this type of gilt suited to investors who want to protect real purchasing power rather than maximise nominal income. The real yield is the return on top of inflation; the cash return depends on what RPI actually does.
Worked example: £10,000 held to maturity
