How MMFs Work: The Mechanics

1

Pool Your Money

Your investment joins thousands of others, creating a large pool that can access better interest rates and investment opportunities than individual investors.

2

Professional Management

Fund managers invest in a diversified portfolio of short-term instruments: government bonds, certificates of deposit, commercial paper, and bank deposits.

3

Earn Returns

You receive income from interest payments on the underlying investments, typically paid monthly or quarterly and can be reinvested for compound growth.

4

Easy Access

Most MMFs allow daily withdrawals, making your money almost as accessible as a savings account but with potentially better returns.
