First of all, the U.S. Treasury controls the printing of money in the United States. But they are not the primary reason for when new money is put into circulation. The Federal Reserve Bank has control of the money supply through its power to create credit with interest rates and reserve requirements. 
When there’s a need for money the Treasury prints it, and when banks need more, the Federal Reserve electronically deposits it into the banks account, and then charges the proper interest rate. Once the bank has caught up financially, it pays back the Federal Reserve. Either way you look at it, it is a combination of the Treasury Department and the Federal Reserve. 

Total Value of Currency is a way of describing how much a certain amount of money is worth. ]This may happen in businesses in which they are able to encourage foreign investors into buying product or stocks. Technically, it’s very difficult to officially tell when our dollar has more worth than the previous day.. but it may comparison to other countries. 

According to investopedia companies are buying their own stocks. This is called Stock buybacks, which is “repurchasing of shares of stock by the company that issued them.”
The reason companies are buying stocks back is because this will raise equity capital through the sale of common and preferred shares.

The federal government recently announced intent to buy large numbers of Treasury Bonds. A successful prediction on buying a bond can help companies. Usnews.com mentioned in their article that “with interest rates on the rise, the relative safety of bonds is getting more appealing by the day for long-term investors”. 
In hope to improve the economy we recommend treasury bonds since interest rates are on the rise!
