Answer: increase in the yield to maturity will lower a bond's coupon rate and hence its price.
Step-by-step explanation:
The yield to maturity is the percentage of return that'll be paid on a bond as long as the investor holds the security till it matures.
It should be noted that the price of a bond moves inversely with the yield to maturity as a rise in the yield to maturity leads to a reduction in the bond's price and a reduction in the yield to maturity will bring about increases in price of a bond
