Bond price and yield

The price of a bond is the present value of its coupons and principal, discounted at the market yield, so price and yield move in opposite directions.

A ten-year bond paying a 7% coupon, when market yields are 8%, is worth ₹93.29 per ₹100 of face value.

That inverse relationship is the whole of interest rate risk. A holder who bought at par and watches yields rise has an unrealised loss, and if they hold to maturity they still receive the full face value, which is why the loss matters for a bank marking to market and not for a saver holding to term.
