Skeptical about skeptics
Changes in interest rates don't affect the face value of the bond nor the coupon rate (the amount treasury pays the bond holder every 6 months). It only affects how much the bond is worth in the open market.If rates rise and the Fed gets the bonds at a discount that differential too is remitted to Treasury eventually when the bond matures.
If the coupon rate is 5% then on a $100,000 bond, Treasury would pay you $2,500 every 6 months. At the end of the 10 years, you would also get back $100,000 for the bond. If the expected rate of return was also 5% then the bond would be worth $100,000 at the start. The situation would be analogous to investing $100,000 in a fixed term bank account and collecting the interest every 6 months. At the end of the 10 years, the bank would return the $100,000 to you.
If the expected rate of return or effective interest rate were only 4%, then since you would need to invest more than $100,000 to get $2,500 every 6 months, the bond would be worth more than $100,000 on the open market. Similarly, if the effective interest rate was 6% then the bond would be worth less than $100,000 on the open market.
Just to get real, according to this SOURCE, the current coupon rate on 10 year bonds is 1.75% and the price of the bond is 93% of its face value. This equates to an effective return of 2.56%.
It is important to realize that Treasury pays the bond holder no matter who holds the bond. Even if it is the Fed that holds the bond, paying what is owed on the bond when it falls due and collecting the Fed's profits at the end of the year are two entirely separate operations so the churn must go on. If the Fed were to buy mortgage backed securities instead of bonds, then the Treasury would still be paying the same amount on the bonds it sold and still be getting the same amount of profit from the Fed (assuming the rates of return were the same).
