*Savings Rate Equivalent = the gross yield a fully-taxable savings account or bond would need to match this gilt's net yield, at that tax rate. Gilt coupons are taxed as income; the capital gain to par is exempt from CGT. Figures don't include your Personal Savings Allowance, so they're conservative. How we calculate this.
TG50 is the UK Treasury gilt "0 5/8% Treasury Gilt 2050", paying a 0.625% annual coupon and redeeming at par (£100) on 22 October 2050 — about 24.1 years away. At its 11 Sep 2026 closing price of £32.62 the gross redemption yield is 5.898%. Because the coupon is low and the price is well below par, most of the return comes as the tax-free pull to par (a £6,738 capital gain per £10,000 nominal, exempt from CGT) rather than as taxable coupon income. That makes it unusually efficient for higher- and additional-rate taxpayers: an additional-rate (45%) payer keeps a net yield of 5.37% — to match that after tax, a fully-taxable savings account or bond would need to pay about 9.77% gross. That is how gilts are taxed in practice: gilt coupons are taxed as income, while the capital gain is free of capital gains tax on any disposal — at redemption or an earlier sale — though interest accrued since the last coupon is taxed as income when you sell.
