Take Marcus, a 54-year-old warehouse supervisor from Dayton, Ohio. He set up his 401(k) in 2021, selected a “balanced income” fund, and never looked at it again. By early 2025, nearly 14% of his retirement savings were sitting in high-yield bond funds he didn’t know he owned, and three of the underlying issuers had already entered default proceedings.

Marcus isn’t unusual. He’s the rule.

Most Americans assume that bond funds are the safe, boring part of their portfolio. The stable counterweight to volatile stocks. The grown-up choice. That belief is now costing people real money, and the data is not subtle about it.

The Default Rate Reality Nobody Is Talking About

Here is the number that matters: According to Moody’s 2024 annual default study, the trailing 12-month speculative-grade default rate hit 5.6% by the end of 2024, up from 2.8% in 2022. That is a doubling in two years. Fitch Ratings flagged in its January 2025 outlook that leveraged loan default rates could push toward 7% through mid-2025 if refinancing conditions don’t ease.

These are not abstract percentages. If 5.6% of the bonds in your high-yield fund default, and you have $80,000 in that fund, you are looking at potential losses on $4,480 worth of underlying debt. Recovery rates on defaulted bonds historically average around 40 cents on the dollar, according to S&P Global data from 2023. Do the math.

Do you actually know what percentage of your portfolio is in high-yield bonds right now?

Most people don’t. And that ignorance isn’t laziness. It’s a feature of how these products are sold.

How “Income” Became a Disguise

Fund managers figured out something useful a long time ago: calling a fund “High Risk Debt” kills sales. Calling it “Strategic Income Opportunity” moves product. So that’s what they did.

A 2023 Morningstar analysis found that 38% of retail investors in high-yield bond funds believed they were holding investment-grade securities. They were not. Many of these funds hold significant allocations to BB-rated and B-rated bonds, which sit below investment grade and carry default probabilities that are 4 to 7 times higher than BBB-rated paper, per S&P’s historical default rate tables.

Warning: If your bond fund has the words “income,” “yield,” “strategic,” or “opportunity” in the name, open the prospectus before your next contribution hits. You may be holding junk-rated debt without knowing it.

The fund industry profits from this confusion. The expense ratios on high-yield funds average 0.85% annually, compared to 0.05% for a short-term Treasury ETF like SGOV, according to ETF.com data from 2024. You are often paying 17 times more in fees for the privilege of holding riskier assets.

What Rebalancing Actually Looks Like Right Now

I spent 15 years on Wall Street. This is what they never tell you: the professionals already moved.

Institutional investors, pension funds, and endowments began rotating out of speculative-grade credit in late 2023. The ICE BofA High Yield Index spread widened by over 80 basis points between September and December 2024, a signal that large money was repricing risk, not ignoring it. Retail investors, by contrast, poured $12.3 billion into high-yield bond funds in the same period, according to the Investment Company Institute’s December 2024 flow data.

When did you last check whether your bond funds were inflation-protected or even benchmarked against something safer?

The gap between what institutions do and what retail investors do is not a knowledge gap. It’s an information gap. Institutional investors have risk dashboards. You have a quarterly statement that arrives when it’s already too late to act.

Did You Know: The Vanguard Inflation-Protected Securities Fund (VTIP) returned 4.2% in 2024 with near-zero default risk exposure, according to Vanguard’s December 2024 fund fact sheet. Many comparable high-yield funds returned less, with significantly more credit risk embedded in the portfolio.

The Liquidity Trap Most People Walk Right Into

Most people get this wrong: they treat their bond allocation as a stability reserve, then find out in a downturn that high-yield bonds and stocks drop together.

During the March 2020 credit shock, the iShares iBoxx High Yield Corporate Bond ETF (HYG) fell 21.4% in less than five weeks, per Bloomberg data. That is equity-level drawdown from an asset investors believed was defensive. If you were planning to rebalance by selling bonds to buy discounted stocks, you had no dry powder left. Both sides of your portfolio were bleeding simultaneously.

If you lost your job tomorrow, how many months of expenses could you cover without touching your investments?

That question matters because the answer shapes how much risk your bond allocation can actually absorb. A person with three months of cash reserves has a fundamentally different risk tolerance than someone with twelve. Your portfolio should reflect that arithmetic, not a generic age-based allocation formula that hasn’t been updated since interest rates were at zero.

Pro Tip: Short-duration Treasury funds like SGOV currently yield above 5% annualized with essentially zero credit risk, per BlackRock’s Q4 2024 fund data. Before holding any speculative-grade bond fund, ask yourself whether the yield premium justifies the default exposure. Right now, for most retail investors, it does not.

The Common Mistake That Compounds the Problem

Here is where it gets worse. Most investors who discover they have high-yield exposure make one specific error: they sell at the worst possible time.

Selling investments during a credit event locks in losses permanently. The Dalbar 2024 Quantitative Analysis of Investor Behavior found that the average equity fund investor underperformed the S&P 500 by 4.35% annually over 20 years, largely due to panic selling. The same behavioral pattern plays out in bond funds, just with less fanfare.

The solution is not reactive selling. It’s proactive rebalancing before default rates climb further. Full stop.

Action Step: Pull your 401(k) or brokerage statement today and search for any fund containing “high yield,” “income,” or “yield” in the name. Write down the exact dollar amount and percentage of your total portfolio. That number is your starting point. Everything else depends on it.

Your Next 3 Steps

Step 1: Log into your brokerage or 401(k) portal today and search your current holdings for any fund containing the words “high yield,” “income,” or “yield.” Write down the exact dollar amount and percentage of your total portfolio sitting in those funds. Not an estimate. The actual number. That figure is your exposure, and you cannot manage what you have not measured.

Step 2: Pull up the fund’s prospectus or its Morningstar page and find the credit quality breakdown. Look specifically at what percentage of holdings are rated BB or lower. If that number exceeds 20%, you need to have a rebalancing conversation this week, with your advisor or on your own. Not next quarter. Not when the market feels calmer. This week. Default cycles do not wait for convenient timing.

Step 3: Benchmark what you currently hold against SGOV or VTIP using the past 12 months of return data. Both are publicly available on Morningstar or your brokerage’s research tab. If your current high-yield fund is not beating those benchmarks by at least 1.5 percentage points annually on a risk-adjusted basis, you are accepting extra default exposure for no meaningful reward. That is not a calculated risk. That is a fee with a bad outcome attached to it.
