Answer:
YTC is 0.2% more than YTM
Step-by-step explanation:
The actual return that an investor earn on a bond until its maturity is called the Yield to maturity.
The actual return that an investor earn on a callable bond until call of bond is called the Yield to call.
Yield to Maturity
Yield to maturity = [ C + ( F - P ) / n ] / [ (F + P ) / 2 ]
Coupon Payment = C = $90
Number of years to mature = n = 25 years
Current Market price = MV = $1,175
Yield to maturity = [ $90 + ( $1,000 - $1,175 ) / 25 ] / [ ( $1,000 + $1,175 ) / 2 ]
Yield to maturity = $83 / $1,087.5 = 0.076 = 7.6%
Yield to call
Coupon Payment = C = $90
Number of years to call = n = 5 years
Callable price = CP = $1,050
Yield to maturity = [ $90 + ( $1,000 - $1,050 ) / 5 ] / [ ( $1,000 + $1,050 ) / 2 ]
Yield to maturity = $80 / $1,025 = 0.078 = 7.8%
Difference between YTM and YTC = 7.8% - 7.6% = 0.2%
