Real yields are returns above RPI inflation. The coupon (including its inflation uplift) is taxed as income — 2 percentage points more from 6 April 2027 (22/42/47%); the inflation uplift on the principal is free of CGT. Figures don't include your Personal Savings Allowance. How we calculate this.

What this means

TR46 is the UK index-linked gilt "0⅛% Index-linked Treasury Gilt 2046", maturing 22 March 2046. Both its coupon and its principal are uplifted by RPI inflation, so the quoted real yield of 2.455% is the return you earn on top of inflation. At its 27 Oct 2026 price of £64.22 (clean, before inflation adjustment) the market-implied break-even inflation is 3.29%: if RPI averages more than that until 2046, TR46 beats a conventional gilt of the same maturity; if less, the conventional gilt wins. The inflation uplift on the principal is free of capital gains tax; the (inflation-uplifted) coupon is taxable as income. That is index-linked gilt tax treatment in practice. Compare it with a conventional gilt. Note: UK index-linked gilts have no deflation floor — sustained deflation can reduce the redemption value below par.
