Cash Management Bill - CMB

A short-term security sold by the U.S. Department of the Treasury. The maturity on a CMB can range from a few days to six months. The money raised through these issues is used by the Treasury to meet any temporary shortfalls.

|||The cash management bill is the most flexible instrument of the U.S. Treasury because it can be issued when needed, allowing the Treasury to have lower cash balances and issue fewer long-term notes. CMBs tend to pay higher yields than bills with fixed maturities, but their shorter maturities lead to lower overall interest expense.
