Which of these actions would the government most likely take if it wanted to stimulate more savings?

If the government wanted to stimulate more savings, it should pay a higher percentage on US Savings Bonds.

United States savings bonds are debt securities allotted by the United States Dept. of the Treasury to support compensation for the U. S. government's debt needs. US savings bonds are viewed as one of the most secure reserves since they are sponsored by the full confidence and credit of the United States government.
