Money-Market Funds & CDs: Americans Grow their Huge Piles of Interest-Earning Cash Further despite Lower Yields

Household money-market funds surged, large CDs also surged. But small CDs are the hot money; they flee when yields drop.

By Wolf Richter for WOLF STREET.

Despite the Fed’s rate cuts of 100 basis points in 2024, and therefore lower yields on money market funds, households continued to pile their cash into them. Banks have lowered the rates they pay on CDs, and holders of small CDs, always the hot money, have started to cash out. But balances of large CDs continue to grow. On net, their huge pile of interest-earning cash grew further.

Balances in money-market funds held by households rose by another $55 billion in Q2 from the prior quarter, and by $650 billion year-over-year, to a record $4.65 trillion, according to the Fed’s quarterly Z1 Financial Accounts yesterday. Since Q1 2022, when the Fed started hiking its policy rates, balances have surged by $2.02 trillion.

These money market fund (MMF) balances include retail MMFs that households buy directly from their broker or bank, and institutional MMFs that households have indirectly through their employers, trustees, and fiduciaries who buy those funds on behalf of their clients, employees, or owners.

MMFs invest in safe short-term instruments, such as in Treasury securities with less than one year to run (anything from a 1-month T-bill to a 30-year Treasury bond that matures in a few months), in high-grade commercial paper, in high-grade asset-backed commercial paper, in repos in the repo market, and in repos with the Fed (ON RRPs).

The Fed’s five rates form a floor and ceiling for short-term market yields, such as the gigantic repo market, to which MMFs are big lenders.

Short-term Treasury yields track the Fed’s policy rates expected in the near future. The three-month Treasury yield dropped in recent days and is at 4.03% currently, fully pricing in one 25-basis point rate cut next week, whereby the Fed would bring its five policy rates down to 4.0% at the low end and to 4.25% at the high end.

Many MMFs still have a yield above 4%. But yields of many Treasury money market funds have fallen below 4%.

But when Q2 ended on June 30, the 3-month Treasury yield was still 4.34%. And so the household MMF holdings of $4.65 trillion at the end of Q2 were still earning the yields prevalent at the time, roughly 30 basis points higher than today.

All these yields are still positive in inflation-adjusted terms: CPI inflation – in another nasty surprise that inflation tends to dish up – rose to 2.9% for August.

If the Fed cuts short-term rates aggressively while inflation continues to accelerate, it won’t take long before real yields on MMFs turn negative.

Falling yields, and especially negative real yields, would suggest that households yank their money out. But as we saw in 2020, nominal yields plunged to near-0%, and by early 2022, real yields were around negative 7% and falling further, and household MMF holdings barely dipped.

But when yields rose sharply later in 2022 and through mid-2023, MMF balances exploded and they continue to surge though yields have backed off by over 100 basis points.

So it will be interesting to see how far yields would have to fall before aggrieved households begin to drain those MMFs. And as we saw, it might not make a big dent.

Total MMFs (those held by households and institutions) rose by $83 billion in Q2 from Q1, and by $933 billion year-over-year, to $7.48 trillion. Since Q1 2022, balances have ballooned by $2.39 trillion.

Small Time-Deposits (CDs of less than $100,000) react fairly quickly and strongly to interest rates offered by banks. They’re not “sticky” at all. They’re the hot money.

In July, balances ticked up a hair from June to $1.06 trillion, according to the Fed’s latest Money Stock Measures. But that was down by $129 billion from just before the Fed began cutting its policy rates in mid-September 2024.

In the time frame of Q2, small CDs fell by $13 billion quarter-over-quarter and by $114 billion year-over-year.

As soon as the Fed started cutting rates in mid-September, which caused banks to cut the interest rates they offered on CDs, balances began to fall.

Balances fall gradually as holders don’t reinvest the proceeds from maturing CDs. Some CDs have short terms, such as 3 months or 7 months, others go out further, 2 years, 5 years, and longer. So it takes a while for balances to drop, as we can see in the chart below.

When the Fed gutted savers’ cash flow from savings in 2008, they began cashing out, and by mid-2022, small CDs had nearly vanished. But note, when the Fed started hiking its policy rates, balances of small CDs exploded from near-zero in April 2022 to $1.19 trillion in August 2024. The hot money!

But Large Time-Deposits (CDs of $100,000 or more) continued to inch from record to record, and in July reached $2.40 trillion, up by $82 billion from a year ago, according to the Fed’s monthly banking data.

In the time frame of Q2, large CDs rose by $32 billion QoQ, and by $82 billion YoY.

Since March 2022, when the rate hikes began, large time-deposits have surged by $982 billion.

So, with…

  • Household MMFs +$55 billion QoQ and +$650 billion YoY, and
  • Small CDs -$13 billion QoQ and -$114 billion YoY, and
  • Large CDs +$32 billion QoQ and +$82 +billion YoY

these piles of interest-earning cash combined increased by $74 QoQ and by $618 billion YoY, to a record $8.11 trillion.

In addition, many Americans hold high-yield savings accounts, but they’re not included here.

In addition, many Americans hold T-bills directly, either in their brokerage accounts or in their accounts at the government’s TreasuryDirect, and they’re also not included here.

CDs are only a small part of total bank deposits. Total deposits at commercial banks rose to $18.3 trillion in July, back where they’d been before the rate hikes and QT. Balances had dropped by nearly $1 trillion in the first half of 2023 during the bank panic that caused three regional banks to collapse. But the FDIC made all depositors whole, the dust settled, and deposits started coming back.

    MW: As Fed nears highly anticipated rate cut, the market ‘really hinges’ on 10-year Treasury yield

    • Bobber says:

      So far, the idea of a lower ST rate has caused mortgage rates to drop. Lenders must think a rate cut is appropriate at this time, even though inflation is still running well above target for the 5th year in a row.

      This result makes little sense to me. I sense bondholder complacency.

      • Wolf Richter says:

        A year ago, mortgage rates dropped until the day of the 50-basis point rate cut. Then on the day of the rate cut, they rose, and they kept rising until they’d risen by over 100 basis points, while the Fed cut 100 basis points.

        We discussed this here in the comments at the time, live, as we were watching it develop on the day of the rate cut. It was interesting.

        • TSonder305 says:

          Unless the bond buyers think that the reduced new jobs means that inflation will die on its own (making the reduced yields more palatable), and that longer-term stagflation isn’t a possibility.

      • danf51 says:

        Are there any Mortgage originators that keep the loans they create on their own balance sheets ? I suspect mostly they sell them off ASAP and just retain the servicing business.

        Given that reality what forces really set the Mortgage rate ? Would it be what the Federal agencies are willing to pay, what the demand is for CDO’s and MBS. I don’t know. It’s a mystery to me.

        If I were a bank would I be willing to keep 30 year paper on my own Balance Sheet for 6% ?

  2. David says:

    Wolf, if the federal funds rate go lower, let’s just say zero for the moment, and those in MMFs move to buy Notes instead of Bills, doesn’t that also force the Treasury to finance it’s debt with Notes?

    • Wolf Richter says:

      No, MMF must cannot do that. They cannot buy anything that matures in more than one year, and their weighted average maturity must be 60 days or less. Those two are what makes MMFs safe. They’re regulatory requirements.

  3. Oh, Shitake says:

    Wolf Man…
    My money in the bank earning maybe 4%….Let’s look a little further…
    Beginning of year $1000. End of year $1040 (more or less). My pile of cash at end of year
    = BIGGER! Yay!!! Well, uh, no.
    That larger pile of cash at year’s end will buy less goods and services that it did on Jan 1st. More pieces of ‘paper’, less purchasing power.

    I’m almost finished with my book, ‘Banking for Dummies’.

    • Wolf Richter says:

      The idea of yield is to be larger than inflation = positive “real” yield. CPI inflation = 2.9%. Yields over 4% = positive “real” yield. If inflation goes to 3.5% and the Fed cuts to 3.0%, then the “real” yield will be negative.

      Read the article. It explains that.

      With stocks, you can lose 50% due to market value decline over three years and lose another chunk due to inflation. So a loss of maybe 60% or more. Or you could make more.

      That’s “risk.” A nearly risk-free asset, like a MMF, has a smaller potential return, than an asset where you can lose 100% of your principal.

      • Great Outdoors says:

        And tax on the yield makes it a harder choice, for anyone earning enough to pay income tax.

      • MM1 says:

        After tax the 4% yield is ~3%. So right now we’re all just breaking even. Real yield will be negative soon.

        • Wolf Richter says:

          All income is taxed eventually. Why is this brought up ONLY with fixed-income investments? Because it’s easier to figure than taxes on your labor, stock gains, etc.? What kind of bullshit is this argument?

          What you should bring up in this discussion is RISK. That’s what is different between these investments, not taxation (in fact, some fixed income investments, such as munis and Treasuries have tax advantages that other investments don’t have).

        • vvp says:

          You can’t let taxes be the tail wagging the dog. This is how you get people buying a home that can’t afford because the mortgage is deductible.

  4. Sandeep says:

    As usual MSM claims to say 7.5 Trillions sitting on sidelines so Stocks will only go up. Complete BS. Now ON RRP have almost vanished. All those Money market funds are invested into Short term/medium term. So its not like that cash is lying around where people can buy stocks.
    If those funds money invested into Stocks, Treasury and Bond markets yields will go up in order to entice the investors. Someone has to buy Govt Debt.
    Sure those high balances are having wealth effects specially retirees who have piles of cash. Even at 4.3% they are enjoying their new revenue stream. This revenue stream was killed by FED for 15 years.

    • Wolf Richter says:

      The “money on the sidelines” is the funniest BS ever, and it refuses to die though we have driven wooden stakes through its heart many times here.

      • Benton says:

        It is absurdity to the extreme because it makes the assumption that the individual who is high or medium risk adverse chasing interest rate returns will suddenly wake up one day and say, “You know. I should take my MM money earning 4.5% and now invest directly into high risk equities at an all time high because my monthly interest return dropped by .5%.” I remember when this same group of individuals were chasing 0.25% CDs and bank MMs in 2010. However, it does make for a good sound bite for equity pumpers to make the argument that the party will keep rolling. The mountain of cash these cash hoarders are holding onto needs to be “…put to work! How dare people attempt to get a moderate or even small return on their money with lower risk!” It took several years for a lot of these slow moving individuals to wake up and just move their money from almost zero bank interest accounts to higher dividend MM accounts. I don’t see the scenario of them now reacting to a a drop from 4.25% to 4% return or even 3.5%.

        • TSonder305 says:

          The dishonest use of the language is intentional. It’s not just “money on the sidelines.” Even “put to work” is dishonest, as it implies that the money will be used to finance capital investment by companies. That’s only true for IPOs and existing companies that are issuing new shares to raise money.

          Most of the “market” is just algos trading the same shares back and forth. That’s not “putting anything to work” in the sense that it’s being described.

      • Gabriel says:

        I am confused. I thought my money in short term t-bills is considered the “money on the sidelines”.

      • Tyler says:

        “and it refuses to die” that’s the problem and also the big question. Will this mindset die or will it thrive –

      • Bs ini says:

        Yep for every buyer there is a seller net gain of zero

    • MM1 says:

      If rates keep dropping but inflation stays where it is or goes higher I think there will be some yield chasing. Earning 3% is 2.25% after tax and losing against inflation. So we could see a portion of this move into stocks. Will it likely move into high risk stocks, no, but I could see it move to dividend stocks with a long history of increasing dividends.

      Similarly if the real estate decline picks up and people decide to sell vacant properties, if they still have equity that money needs to go somewhere.

      Not saying 3.75% would the line but anything below 3% is kinda pointless to stash money in, although better than a checking account I guess.

  5. TEF says:

    Wolf, what is the ratio between people investing mostly in the stock market and those mostly in interest bearing instruments at the moment? Not an easy thing to estimate, but is it high, medium or low as a percentage and has this changed significantly? If 10% are in interest ones instead of only 5% does that really mean much?

  6. JustAsking says:

    Short term CDs flee to where?

    The system is awash with liquidity….still. And the Fed seeks a reason to cut….

    The dollar index chart doesnt look so good.

  7. Xavier Caveat says:

    Most of the money on the sidelines i’ve seen was in San Pedro among sodden sailors.

    • Andrew pepper says:

      Wolf, lots of talk about money supply, interest, and inflation. But what really makes up the ‘money supply’? Yes, I know it is the money stock and circulation of that money stock, but what about the Bitcoins, Stable coins, gold, silver, etc. Perhaps the term money supply should be redefined to include these other monies. This might help to explain how much inflation we, in my opinion, are going to get.

  8. JoshWx says:

    Whether it’s CDs or stocks or whatever, it’s almost impossible not to make out like a bandit right now. “Just dump everything into the market” continues to work, for the time being. Friends and coworkers (mostly Millenials and Gen Z) are all banking on the fed put to backstop any material setbacks and keep the bubble going.

    God forbid the job market actually begins to fall apart, pretty much everyone expects both a fiscal and monetary response that will send things back to astronomical levels (checks to households, deficit spending, slashing interest rates to zero, etc). BTFD to eternity and beyond.

    It all works until it doesn’t. Find me a short ETF that’s a bundle of BNPL services for when it all eventually comes apart.

    • TSonder305 says:

      Yep. And I’m sure when the job market does begin to fall apart, there will be pressure from the media and others for Congress and the Fed to “do something.” The real concern would be losing the confidence of foreigners in the U.S. dollar. If your policy ever time there is a recession is to print your way out of it, why would anyone want to hold dollars?

      The COVID response can be dismissed as a one-time thing, but if that becomes a model, I can see the beginning of the end of the reserve currency.

      • MM1 says:

        The fed is panicking and cutting with unemployment at 4.3%, still below historical norms and their year end target. I’m skeptical they’ll let unemployment rise…

      • 4hens says:

        The COVID response was similar to the financial crisis bailouts. Pretty straightforward Keynesianism. Except Keynes thought there should be high taxes during good times to pay for the bad times bailouts. That part hasn’t been done.

    • vvp says:

      People below 50 investing in their retirement accounts won’t be touching it for decades. The momentary behavior of markets is irrelevant.

      Zero Hedge has probably cost people more money at this point than any combination of market crashes.

  9. GloomyGus says:

    Are there many people who don’t think that the “Fed’s” playbook has already become the de facto backstop for anything bad that could ever happen… …the QE and fiscal response to COVID “worked”… and proved to an entire generation (and maybe me too) that you can have money without working and nothing bad really happens… (except maybe that I never got any money, personally). The business cycle has been repealed and anything that looks contractionary is really just the Fed not doing its’ job.

  10. Wolf, as always I appreciate your analysis. It helps the financially inept like myself understand these things.

    We have a savings account earning 3.8%, which remains shocking to me because the Savings rate at a much larger institution in 3.7% less than that. It has been a long time since I remember those kinds of rates being that relatively high.
