单选题

Which of the following is least likely a tool used by the U.S. Federal Reserve Bank to directly influence the level of interest rates?

A、 Verbal persuasion
B、 Open market operations
C、 Setting the rate on 30-year bonds

【正确答案】 C

【答案解析】

C is correct because the U.S. Federal Reserve Bank (Fed) uses policy tools to directly influence short-term interest rates. It only indirectly influences long-term interest rates. The market, not the Fed, sets rates on 30-year bonds.
