Buying a 100,000 yen bond keeps the capital sum safe while also providing regular payments to the saver. To be precise, the bond pays a fixed rate or 'coupon' of 1.5 per cent: 1,500 yen a year in the case of a 100,000 yen bond. But the market interest rate or current yield is calculated by dividing the coupon by the market price, which is currently 102,333 yen: 1,500 ÷ 102,333 = 1.47 per cent.
