Households added $89B to money market funds in Q1, pushing balances to $5.21T. With inflation at 4.2% and MMF yields at 3.5%, real returns are now negative 0.7%.
Households added $89 billion to money market funds in the first quarter, pushing total balances to $5.21 trillion, even as inflation began to outpace the returns those funds generate. The Federal Reserve's quarterly Z1 Financial Accounts show the pile has roughly doubled since the central bank started raising rates in early 2022.
MMFs currently yield about 3.5%, down from over 5% before the rate cuts began last September. Treasury bills, the closest substitute, offer between 3.66% (four-week) and 3.91% (one-year) at this week's auctions. Inflation, measured by the Fed-preferred PCE price index, hit 3.5% in March and surged above 4% in April and May. At May's CPI reading, the real yield on MMFs stands at negative 0.7%.
The mechanics are straightforward. MMF yields come from the short-term instruments they hold minus fees. Three-month Treasuries pay 3.71%, six-month Treasuries 3.80%, and asset-backed commercial paper yields 3.75% to 3.85% for 30- and 90-day paper. The gap between these rates and the 3.5% investors actually receive is the fee skimmed by the fund provider. The Fed's overnight reverse repo facility, which pays near zero, has seen near-zero activity as a result.
Banks are also seeing a flood of cash. Large time deposits – certificates of deposit of $100,000 or more – hit a record $2.52 trillion in April, up $49 billion from March and $169 billion year over year, per the Fed's H.8 report on bank balance sheets. Since rate hikes began in March 2022, large CD balances have surged $1.11 trillion. Small CDs, those under $100,000, ticked up to $1.02 trillion in April after six consecutive months of decline, the Fed's H.6 money stock data shows.
CD yields are starting to climb. Brokered CDs now offer yields above 4% APY for terms of nine months or longer at some brokers, beating T-bills. That suggests banks expect rate hikes and are competing for deposits from yield-seeking buyers.
For investors holding cash in MMFs and CDs, the math is straightforward. The nominal yield on these instruments is below the current inflation rate, meaning purchasing power is shrinking. The Federal Reserve may raise rates later this year – the bond market currently prices the first hike around year-end and another in 2026 – but even if those hikes materialize, real yields will likely remain negative if inflation stays elevated.
Inflation eats everyone's lunch one bite at a time, sometimes more slowly, other times faster, whether real estate or stocks or bonds or cryptos or MMFs or CDs. Some other investments come with the hope of big capital gains that will outrun inflation. That has a history of working, and of not always working. If those investments have capital losses, the curse of inflation is added to the capital losses, making those losses even harder to swallow.
Other investments come with automatic inflation protection. Treasury Inflation Protected Securities (TIPS) and Treasury I-series savings bonds earn an inflation protection amount based on CPI that is added to the principal as it occurs, plus a low separate yield.
And by the looks of it, higher-than-2% inflation is here to stay. Neither this administration, nor probably the next administration, nor the Federal Reserve, nor Congress is unhappy with inflation in the 3-4% range or maybe in the 3-5% range. That type of inflation makes the fiscal mess the US is in a little less unsustainable.
