What’s the Difference Between Money Market Funds and Money Market Accounts?

by Jessica Sommerfield · 9 comments

I’ll be honest: I’ve never really understood the difference between money market funds and money market accounts.

Recently, however, I read a few articles that showed me the basic differences between these two investments, and I want to pass my new knowledge on to you.

First of all, both money market accounts and money market (mutual) funds are liquid investments that can be easily transferred back into cash. The vital differences are: who you’re investing with, the security of your funds, and the yield rates. 

Money Market Funds Vs. Money Market Accounts

Who You’re Investing With

Money market accounts are made with your bank, and can be viewed as a type of savings account that involves some investment to increase your rate of return. The investments are usually low-risk options like certificates of deposit or treasury notes.

Money market funds, on the other hand, are true investments. They’re invested directly into government bonds or what is known as  “commercial paper,” a type of termed, low-risk investment into large corporations.


Although both money market accounts and funds are considered shorter-term, low-risk investments, there’s a major difference in how secure they are. Just as your checking and savings accounts at your bank are FDIC-insured for up to $250,000, so are money market accounts. This adds a certain level of security for even the small amount of risk involved.

But money market funds are not secured by the government, and thus are subject to loss. This is one reason there were such massive withdrawals of money market funds during the financial crisis of 2008.

The government recently issued a few new laws under the Securities and Exchange Commission designed to set withdrawal limits — in hopes of preventing this from happening again. But don’t worry: if you have money market funds, the withdrawal limits shouldn’t affect you. These new laws are designed to keep large corporations with significant holdings from withdrawing massive amounts and causing huge swings in the market.


Since higher risk investments are usually higher yield, it’s logical that money market funds produce higher yields (profits). This is usually true, but not in the current economy.

Interest rates are so low right now that money market funds aren’t as profitable as money market accounts with a bank. In the realm of online banking, money market accounts are yielding as much as 1% interest.

Which Should You Invest In?

If you want highly liquid funds that are easy to access, you probably want to open a money market account with your bank. On the other hand, if you already have an investment portfolio and are looking for a cash investment that’s easy to move around and liquidate, you’ll benefit from money market funds.

Honestly, both are a good idea. Since interest rates are currently higher on money market accounts, I’d focus on them first. But, if the economy improves, the rate of return on money market mutual funds will again exceed that of money market accounts.

Understanding the difference between these two types of money market investments has helped me understand which option is best for me. I hope it does the same for you!

Do you have a money market account or fund? Or both?

    Great article. For those who can afford to have $ “locked” up for a certain time period, money market funds will be the way to go. If you prefer liquidity – then go with money market accounts via your bank.

    Great post! Thank you for helping me understand the difference between a money market fund and a money market account. I really like how you explained that “Money market accounts are made with your bank, and can be viewed as a type of savings account that involves some investment to increase your rate of return. The investments are usually low-risk options like certificates of deposit or treasury notes.” I have never had a money market account before, but it is good to know the benefits of having one if I ever need to have one in the future.

  • Ryan says:

    But the real question is which is better for an emergency fund? Neither have decent investment potential but an E fund needs to be easily accessible, even if it does cost you more with miniscule interest.

  • Ben @ superwealthsecrets.com says:

    Well explained. I am thinking to invest in money market account, thanks for the information.

  • Stefanie @ The Broke and Beautiful Life says:

    I honestly never knew the difference either. I’ve found some savings accounts with better returns though, so I’ve never used them.

    • David @ MoneyNing.com says:

      Oh, if you are talking about money market accounts vs online savings accounts, then note that money market accounts allow you up to 3 checks a year. For most of us regular folks, we can think of them as a hybrid between a checking and a savings account.

  • Kirsten @ Indebted and In Debt says:

    I never knew there was a difference (I have a money market account). Thank you for explaining 🙂

    Maybe it’s because I’m such a newbie at investing, but I don’t get why so many people withdrew money in 2008. Because it was federally unsecured? I just left my money where it was a never thought twice.

    • David @ MoneyNing.com says:

      Fear certainly plays a part, along with people actually needing money because of job lost/general ongoing expenses.

      Good for you to stay the course Kirsten. Keep doing what you are doing and you’ll do well 🙂

      Some people, out of fear, withdrew their cash at brokerage money market accounts because it is not FDIC insured and one or two brokerage money market funds broke the buck–the $1 price per share, meaning a share dropped below $1. Some people like me had more than $250k in cash accounts at one bank so I had to withdraw the excess and open accounts at other banks. When the Recession started, the FDIC limit was only $100k, so I had to open accounts at over 10 different banks.
