The Risks and Rewards of Diversifying Your Bond Funds

With interest rates so low, some advisers think investors have too much to lose by focusing solely on bond index funds
Baby boomers investing for retirement back in the ’80s, ’90s and ’00s rarely had to worry about the bonds in their nest eggs.
Bonds back then mainly served as risk-reducing ballast for when stocks tanked. And they weren’t that much of a sacrifice because they often paid healthy interest yields of 5% or more.
But now, when boomers are supposed to have increased bond weightings in their portfolios—40% or more of a nest egg, according to the conventional wisdom—rates have fallen to the floor. Interest yields on a bond index fund are as low as 1.1%. As a result, retirees and other index bond investors are left staring at tiny interest coupons and a greater risk of rising rates, and thus of lost principal.
“With interest rates near their historic lows, so close to zero, there’s generally only one direction they can go,” says Steve Kane, a manager of the $90 billion MetWest Total Return Bond fund (MWTRX).
In response, investors might want to consider adding to their fixed-income portfolios some bond funds that can offer higher yields than U.S. bond index funds and offer varying degrees of protection from the risk of rising rates. At the moment, commonly used bond-market calculations suggest that for every percentage-point rise in rates, a U.S. bond index fund will lose about 6% in price, wiping out years of interest receipts.
The main reason bond index funds are likely to get hit so hard is because of a feature in the index funds’ most widely used benchmark, the Bloomberg Barclays U.S. Aggregate. The “Agg,” as it’s known, is heavily weighted to the most conservative U.S. government bonds.
This investment-grade-only index is thus more vulnerable to rising rates because it doesn’t include some riskier categories of bonds such as high-yield, or “junk,” bonds, or floating-rate loans that pay higher interest and are often found in actively managed bond funds.
Indeed, sponsors of some actively managed target-date mutual funds—multiasset funds whose mix of investments grows more conservative as investors age—take action to serve retirees’ need for extra income by adding “diversifying buckets” of funds that aren’t part of the Agg index.
T. Rowe Price Group Inc., for example, puts about one-sixth of the bonds in its target-date fund for 70-year-olds in high-yield (or junk-bond), emerging markets and floating-rate funds. JPMorgan Chase & Co. puts one-fifth of retirees’ bonds in high-yield and emerging markets.
A series of retiree investment models designed by Morningstar personal-finance director Christine Benz allocates 14% to 22% of bonds to such categories, depending on investors’ risk appetites. Such bonds can “bump up yields and provide extra diversity,” Ms. Benz says.
The interest rates on these three kinds of funds may be double or triple that of a bond index fund. And funds that focus on some bonds, like high-yield and emerging markets, often outperform the index over a full market cycle. Funds of both types beat the index in the past decade, according to Morningstar.
These types of investments do make retirees’ portfolios riskier, however. All three categories got hit twice as hard as the safer index early last year, falling more than 20% in price while bond index funds fell just 8.6%, Morningstar says. Stocks fell 35% during the same period. Most of the losses have since been regained.
Still, seeking to avoid such swings is why some target-date fund sponsors, especially index managers like Vanguard Group, tend to avoid emerging-markets, junk and floating-rate bond funds.
Maria Bruno, head of U.S. wealth-planning research at Vanguard, says trying to boost bonds’ return this way is misguided. Ms. Bruno agrees with those who say bonds should be “ballast” for times when stocks tank. “They shouldn’t be seen as a return-generating investment,” she says.
Dan Oldroyd, head of target-date strategies at J.P. Morgan Asset Management, disagrees. Mr. Oldroyd says that with stock valuations “stretched,” adding risk in a bond bucket with high-yield and emerging markets is a reasonable step. Similarly, Kim DeDominicis, a target-date portfolio manager for T. Rowe, says high-yield and emerging-markets funds can offer possible higher returns and guard against rising rates with “modest increases to expected volatility.”
The target-date funds discussed earlier, including similar Vanguard funds, and the Morningstar buckets all include inflation-protected-bond allocations of 7% to 15% of total assets. While those bonds have yields near zero, they can help protect purchasing power if inflation kicks up.
Riskier, higher-yielding assets are common in actively managed bond funds. A majority of the dozen largest report holding more than 5% of assets in high-yield bonds; five say they have more than 5% in emerging-markets debt.
The $70 billion Bond Fund of America has 6.9% in high-yield and emerging markets. Margaret Steinbach, a fixed-income director for the fund, says higher doses of these kinds of riskier allocations “could potentially compromise the downside protection” of bonds.
But others are more gung-ho. “We’ve been adding high-yield and emerging-markets bonds,” says Mike Collins, co-manager of the $64 billion PGIM Total Return Bond Fund, which holds 14.8% in the two categories. He says individuals could hold as much as half of their bonds in such riskier buckets, depending on their time horizon and risk tolerance.
For do-it-yourself index investors who want to add such exposure, Ms. Benz suggests Vanguard High-Yield Corporate fund (VWEHX), iShares J.P. Morgan USD Emerging Markets Bond (EMB) exchange-traded fund and Fidelity Floating Rate High Income fund (FFRHX).
Less-daring options include bumping up the yield only slightly with an investment-grade corporate bond fund, or moving some bond assets to lower-yielding money-market funds or short-term bonds to reduce interest-rate risk.
Morningstar bond-fund analyst Eric Jacobson says retired bond investors can also try to boost returns more safely by choosing an active manager from among top core-plus bond funds—which typically allocate 15% to 20% of their assets to riskier debt—such as Mr. Kane’s MetWest Total Return Bond fund, Dodge & Cox Income (DODIX) or Fidelity Total Bond ETF (FBND).
While that requires paying a much higher fee on one’s entire bond bucket than for a bond index fund, Mr. Jacobson notes that active bond managers have generally outperformed the index, thanks partly to the riskier assets.

Strong family financial planning can help reduce taxes and support younger generations. From intrafamily loans and asset gifts to inheritance disclaimers, strategic cooperation can create meaningful financial benefits—when families have the trust and structure to make it work.
Happy is the family whose members—parents, grandparents and grown children—trust each other enough to cooperate on shared goals, especially financial ones. When that is truly the case, Uncle Sam’s tax rules can help as well.
This matters especially now that mortgage rates are above 7%, and many families are looking for ways to help younger members. If the elders have resources and are confident younger ones can cooperate, a family loan could make homeownership possible while providing the elders with a useful income stream.
Other strategies can actually lower taxes, such as when funding 529 plans or Roth IRAs, or when someone inherits a traditional IRA with required withdrawals larger than they will need.
Here are three strategies useful for functional families.
It is perfectly legal for families to lend money to a relative for a down payment or even a private mortgage.
But it is important not to cut corners, says Ryan McKeown, a CPA with Modern Wealth Enhancement in Minnesota. If the loan is for a down payment, be honest with the mortgage provider and have a formal agreement. The lender owes tax on the interest payments received.
If the loan is for a private mortgage, both sides should have legal representation with a formal written agreement, including payment terms. The lender owes tax on the interest, and the borrower often can deduct it if he or she itemizes.
To avoid IRS trouble, the interest rate shouldn’t be lower than the agency’s Applicable Federal Rate at the time of the loan. Currently that is about 5% for loans longer than nine years; about 4.5% for loans three to nine years; and about 4% for loans three years or less. Currently, traditional mortgage rates are generally above 7%.
In addition, the lender could use the $19,000 annual gift-tax exemption (described below) to forgive some or all of the interest or principal annually. If both lenders and borrowers are married, that is up to $76,000 a year. There is no tax for the borrower on such forgiveness, because it is from a gift.
If you’re going this route, McKeown advises against having a fixed plan to forgive the debt. Instead, do it in one-off letters specifying the amount—and keep careful records. Otherwise the IRS might try to treat the loan as a taxable gift.
Powerful tax-saving moves for families often use gift-tax provisions. Under current law, anyone can give anyone else up to $19,000 of assets annually, free of gift tax. That means a married couple with three grandchildren could give them a total of $114,000 in 2026.
The gifts can be cash or other assets, like stock. For noncash gifts, the cost basis—which is the starting point for measuring taxable gain after a sale—“carries over” to the recipient. So if someone buys $1,000 of stock and gives it away when it is worth $5,000, the recipient’s cost basis is $1,000. If the recipient later sells the shares for $8,000, the taxable gain is $7,000.
Here’s an example showing how gifts could save a family taxes. Grandma is a widow of modest means, while her child and spouse have prospered. The couple has two children, and they want to contribute $5,000 to a 529 college-savings plan for each—but they need to sell stock to do it. Their tax rate on the sale would be 18.8%, and they would need to sell about $11,000 of stock.
However, Grandma’s federal tax rate on the stock sale is 0%. If the couple gives $10,000 of shares to Grandma, she could sell them, pay no tax, and fund the grandchildren’s 529 plans. This saves about $1,000 of tax.
These moves are legal, and they could be used in other ways, such as to help a young person fund a Roth IRA.
But trust among family members is essential: Under the law, givers can’t put conditions on a gift. Grandma could use her stock proceeds to take a cruise, but she makes 529 contributions instead.
Mark Sellner, a retired tax attorney and CPA living in Sarasota, Fla., uses this strategy. His children sell stock he gives them and fund 529 plans for his grandchildren.
The family’s tax savings aren’t huge, but he likes other benefits. The sales by his children don’t boost his adjusted gross income, which in turn could raise his Medicare Irmaa premiums or his 3.8% surtax on net investment income.
Sellner doesn’t worry about his children using the funds for another purpose.
“There can’t be any strings attached to gifts. Of course, it is up to us to decide whether to make them in the future,” he says.
Two caveats: The “kiddie tax” applies to most children under age 24, and it is levied at the parents’ rate on investment income above $2,700 in 2026. Consider this before making gifts to a young person.
Investors who give away stock also forgo the step-up, an important provision that exempts assets held at death from capital-gains tax.
Sellner knows he’s losing a step-up, but says, “The children could use a little more now. Why should they wait 20 years to get it?”
A disclaimer is a highly useful strategy in which one heir renounces an inheritance in favor of another heir. Assuming family members cooperate, this can save taxes.
Here’s one example. Dad died and had a large traditional IRA that he left to Mom. She has enough assets and income to cover her expenses, and she lives in a state with a stiff estate tax. The inherited IRA would put her estate over the threshold.
Also surviving are three young-adult children. If Mom disclaims all or part of Dad’s IRA within nine months of his death, that amount could go directly to the children. They will have 10 years to empty the account, and the family as a whole will likely save estate and income taxes.
Disclaimers have many key details, especially regarding beneficiary documents. Although heirs have great freedom in choosing what assets to disclaim, the rules about who gets disclaimed property are rigid. It is best if the original owner names tiers of heirs so that if one disclaims, the next recipient is clear.
