We knew this day would come, after enjoying 5% nominal yields on very safe investments for more than a year. But that era ended Wednesday when the Federal Reserve cut its federal funds rate by 50 basis points, to a range of 4.75% to 5.00%.
Today, the effective federal funds rate is 4.8%, and that means almost all safe investments already have or will soon follow the trend below 5%. Look at this chart to see how the 4-week Treasury bill — the base rate for Treasury money market funds and high-yield savings accounts — follows closely with the federal funds rate.

The yield on a 4-week T-bill hit a 2023 high of 6.02% on May 25, 2023, and then a 2024 high of 5.56% on May 24. Thursday, it reached the low for the year, 4.87%. And that yield will continue to decline as the Federal Reserve embarks on a course of rate cuts, probably through much of 2025.
For me, 5% is a magic number. When I was young, my neighborhood Savings and Loan offered a passbook savings account paying a flat 5% and that continued for years. This was the “routine” yield on savings in the 1960s. I remember an episode of the Beverly Hillbillies where banker Mr. Drysdale yelled out, “We’re holding the line on 5% interest!”
I was probably the only kid in America who laughed at that line. More proof I was, and still am, a nerd.
The trend is down
Over the last couple years, I’ve gotten a lot of feedback from readers who were choosing T-bills paying a nominal 5% over TIPS and I Bonds with inflation-protected returns. “Great choice,” I said, if your investment target is short term. But if the goal is longer term, “These rate won’t last forever.”
Here is a look at current yields of safe investment choices, both short- and longer-term. Yields across the board have already dropped below 5% or will soon get there.
A new strategy?
Instead of new strategy, maybe investors need new expectations.
“If you haven’t locked into a 5% yield yet, it’s probably too late for terms over one year,” said Ken Tumin, founder of DepositAccounts.com. “But 4%-plus mid-term and long-term CDs are still available. If interest rates keep falling, these too will soon be gone.”
Tumin advises looking for “add-on” CDs, which allow you to continue depositing money into the existing CD at its current rate.
“In addition to standard CDs at online banks and credit unions, there are a few 4%-plus add-on CDs and no-penalty CDs still available. Moving some cash into these can at least help you maintain 4%-plus yields for a few years into a low-rate cycle.”
I have been a strong proponent of investing in T-bills as part of a 2nd-level cash reserve, setting money aside to be used when needed. Back in July 2022 I suggested staggering investments in 13-week and 26-week T-bills, with some maturing every four weeks and then being rolled over. I followed my own advice and was able to ride T-bill rates from about 1.7% in 2022 to 4.87% on a T-bill I reinvested last week.
At this point, I don’t see any need to abandon this strategy. I need this cash reserve for potential spending in retirement, and I don’t want to increase risk in my portfolio. My potential returns will be smaller, but not drastically smaller for the next year, at least.
On the flip side, my core longer-term bond holding — the Vanguard Total Bond Fund ETF (BND) — has recovered nicely since the disastrous performance of 2022, when it was down 13.1%. BND had a total return of 5.66% in 2023 and is up 4.85% so far in 2024. It’s current SEC yield is 4.03%.
While short-term interest rates are almost certain to decline, there’s no certainty about longer-term rates. So there could be future opportunities to extend duration and lock in safe interest rates of nearly 4.0% — either with CDs or Treasury notes. The bond market has to settle down and adapt to the Fed’s actions.
This time around, most probably, short-term interest rates aren’t heading to zero. A more likely “neutral” level will be in the range of 3.00% to 3.50%. Annual U.S. inflation is currently running at 2.5%, and my goal as an investor would be to maintain yields above the rate of inflation. That should be possible over the next year.

















I was already forced onto the ID.me boat before TreasuryDirect moved to it, so it's not affected my I-Bond purchase…
