“Remember that longer-term/lower-coupon bonds go down more in price than shorter-term/higher-coupon bonds do when interest rates rise,” he said.

Could someone please explain the quote above? Why's it true?

  • When the coupon is high, any change in interest rate is relatively less important. For example, if you have a 10% coupon and interest rates rise from 0% to 1%, your absolute RoI is still 9%, not a huge change. But if the coupon was only 2%, your RoI got halved
  • With short term bonds, interest rates matter less because you can always hold a bond to maturity, and the return of the principal makes up a much greater part of the value of the bond than the coupon.
