Understanding Money Market
The money market plays a crucial role in the financial system by providing a venue for short-term financing. It enables institutions to manage cash flows, balance reserves, and meet regulatory requirements. Central banks use the money market to influence interest rates and implement monetary policy.
Participants include commercial banks, central banks, corporations, mutual funds, and governments. Because instruments are low-risk and short-term, the money market is considered a safe place for temporary cash investments.
