Final answer:
Calculating a bond's yield to maturity involves a complex formula that requires a financial calculator or an iterative process for exact figures. If the yield to maturity rises to 9.5%, the bond's price will drop to reflect the new market rate, as there's an inverse relationship between bond prices and interest rates.
Step-by-step explanation:
When calculating a bond's yield to maturity (YTM), we are assessing what the return would be if the bond is held to its maturity date and all the payments are made as scheduled. The current price of the 10-year, $1,000 bond with an 8.3% coupon rate is $1,034.65, and it issues semi-annual coupons. To find the YTM here, one would need to solve the present value of the annuity formula, involving the coupon payments and the face value of the bond, equal to its current market price. However, as this calculation can be complex and requires either the use of a financial calculator or an iterative process, we will provide conceptual guidance instead of a numerical answer.
If the YTM changes to 9.5% APR with semi-annual compounding, the bond's price will decrease. This is because the required rate of return is higher than the coupon rate, and thus, the bond must be discounted to offer the new buyer a yield equivalent to the market rate. Again, the calculation must be made using the present value of the annuity formula. The example given earlier illustrates that the value of the bond decreases when market interest rates rise, reflecting the inverse relationship between bond prices and interest rates in the market.
