I bought more than “a year of spending” in FFRHX two weeks ago. (Fidelity Floating Rate High Income Fund.) This post gives more information on FFRHX and similar funds. I recommend you buy FFRHX or a similar fund for at least one year of spending. The addition of FFRHX gives you a more stable source for cash for your spending when stocks tank – when you want to sell something other than stocks to give them time to recover.

Patti and I have held IUSB as our primary bond fund since late 2014. (iShares Core Universal USD Bond ETF.) I show 20 years of history of FFRHX as compared to an Intermediate-Term bond index fund similar to IUSB. (IUSB was first formed in 2014.) I include money markets fund and US stocks as reference. See here for more detail on this image. You will also see that FFRHX has steeper declines but faster recoveries. US bonds have not recovered from their depths in December 2022: 45 months and counting.

Stock decline of -37% in 2008: intermediate-term bonds held up: 50 percentage points better in return, but FFRHX did not: 30 points less in return than intermendiate bonds.
Stock decline of -24.5% in 2022: intermediate bonds offered no protection; they declined -24% in 2021+22. FFRHX was better by 16 percentage points over the two years.
Over the last ten years, FFRHX outperformed intermediate bonds by 3.8 percentage points real return per year: 2.2% vs -1.6%. That’s significant: FFRHX compounds to 45% more spending power.
You have many choices. My table compares four funds similar to FFRHX. Morninfstar has a long list. FFRHX looks the best to me.

Details
== Two different kinds of funds ==
FFRHX and IUSB are two different types of funds.
• FFRHX and similar funds. I think of FFRHX (almost) as a high interest money market fund: the duration of the fixed interest period on the securities it holds is typically less than three months. It’s in a category called Bank Loan funds: senior loan or floating rate fund category.
FFRHX and similar funds buy loans issued by banks or other financial institutions to companies. These are higher risk, floating rate term loans. Rates typically adjust every three months. This is “senior debt,” meaning it would be the first to be paid in the case of default; loans may not be fully collateralized. Rates are above the prime rate and adjust with changes in the rate. (Prime now is 6.75%.) As prime increases, FFRHX’s return increases. As prime falls, its return declines.
• IUSB and similar funds. I think of IUSB as an intermediate-term bond fund: it holds fixed interest rate bonds with an average term of ~five years. It’s is a “Core plus” bond fund because it owns a wide mix of securities (US government, corporate) with wide a range of bond ratings and maturities: IUSB holds 18,100 securities; I can’t find another fund that owns more.
The price and therefore the total return of bonds move in the opposite direction of interest rates. As interest rates increase, the fixed interest payments on the bonds it holds are less attractive; bond prices fall to the point where they match the rate paid on newer bonds. As interest rates decline, the fixed interest payments on its bonds are more attractive; prices on bonds it holds increase to match the rate paid on newer bonds.
== We’d like bonds to earn a real return ==
We’d like bonds to earn a real return. We want them to least maintain their same spending power in year after year (That’s what Patti and I target: the same number of years in real spending power at the start of each calendar year.). Bonds our insurance when we don’t want to sell stocks, but if they don’t keep up in real spending power, we have sell stocks just to buy more bonds just to get them to where they should be.
Historically, intermediate bonds have earned 1.9% real return per year over the last 100 years. Over the past 20 years, they’ve earned 0.3%. They’ve returned -1.6% per year for the last ten, meaning, Patti and I typically sold stocks for our spending for the upcoming year and then sold more stocks to buy bonds to maintain their real spending power.
We don’t have a 100-year history for FFRHX or an index of variable rate loans, but FFRHX returned 2% real return per year over the past 20 years and a bit more than that over the last ten years. Had Patti and I held FFRHX for the last ten years, on average we wound not have sold stocks to buy bonds to maintain their spending power. They would have performed well enough that we could have sold bonds to buy more stocks: that would have been a good thing.
== We want bonds to hold up when stocks crater ==
We hold bonds as insurance: the thing we will sell when stocks crater to give them time to recover. Stocks can crater in recessions: we’ve had three since 2000. Stocks declined sharply in each. The worst was a real decline of -38% in the three years 2000, 2001, and 2022; the steepest was -37% in 2008.
The Federal Reserve fights a recession by lowering interest rates to stimulate our economy. Bond prices and total return increases.
Bonds have been good insurance. They’ve outperformed stocks by and average of 35 percentage points in seven of the worst ten years for stocks. Their best year relative to stocks was 2008 and their worst ever was 2022.

== IUSB worked its magic in 2008; FFRHX did not hold up ==
The longest recession in the last 60 years was from late 2007 to mid 2009. Stocks cratered -37% real return in 2008. The Fed aggressively cut rates. The rate it charged banks fell from 5.25% to 0.11%. Bond prices and total return soared. Intermediate bonds outperformed stocks by +50 percentage points: -37% real return for stocks and +13% real return for intermediate bonds.
If Patti and I were retired at the end of 2007, we clearly would have sold only bonds for our spending in 2008. Because they gained in the year, we would be selling a relatively small percentage of the shares we held in a bond fund.
FFRHX did not hold up. Interest rates fell. They should have not earned as much as the prior year, but the price of the loans it held fell steeply (-16.5% real return) on fears of defaults. If Patti and I only had FFRHX for our spending for 2008, we would have sold a relatively high percentage of shares.
The fears of default were unfounded, and FFRHX recovered from its decline in less than a year.
== IUSB failed us in 2021+22; FFRHX did not ==
The Fed was fighting short-lived (three month) recession starting in mid 2020, and then it turned its attention to fighting inflation. The Fed raised the rate it charges banks from 0.09% in July 2020 to 5.06% two years later. The 10-year rate on US Treasury bonds increased from 0.55% in July 2020 to 4.88% in May 2023. Bonds prices collapsed. The total spending power of bonds declined -24%. That’s the worst two-year decline in history.
Patti and sold IUSB at the end of 2022 to get the cash we needed for spending in 2023 even though that was a relatively high percentage of shares. I assumed (correctly) that stocks would rebound much faster than bonds.
Bonds are still 20% below their spending power at the end of 2020. I had to sell a significant amount of stock (I mostly sold in November 2025.) to buy bonds to get them back to the proper level of insurance – to match the level we held at the end of 2020.
FFRHX held up much better in 2021 and 2022. They declined -8% over those two years, one-third the dive of bonds. If I had FFRHX I would have sold a much smaller percentage of shares to get the cash for our spending for 2023. FFRHX recovered that decline in one year. By the end of 2025, FFRHX was 10% more than their value at the end of 2020 meaning I would not have had to sell any stocks to get them back to the same spending power in 2020.
== I recommend you hold some of both ==
I’m roughly 50% IUSB and 50% FFRHX for the +three years of spending that I hold in bonds.

== Other options ==
You have other options than FFRHX as shown on this table. Also see here. FFRHX looks like the best choice to me.

Conclusion: I bought FFRHX (Fidelity Floating Rate High Income Fund) several weeks ago. We now are about half in FFRHX and half in IUSB for our bonds. I start each year with the spending for the year in money market and then three years of spending in bonds.
