You can adjust a portfolio for higher interest rates without predicting the next Federal Reserve move: check whether your goals and target allocation still fit, review the rate sensitivity of your bond holdings, and rebalance by a rule you chose in advance. Rising rates can pressure existing fixed-rate bond prices, but that alone does not determine the right mix of investments for you.

Why rising rates can affect bond prices

Market interest rates and prices of existing fixed-rate bonds generally move in opposite directions. When new bonds offer higher rates, older bonds with lower coupons may become less attractive, so their market prices can fall. The SEC describes this as interest-rate risk in its Fixed Income Investments — When Interest Rates Go Up, Prices of Fixed-Rate Bonds Fall.

The effect matters if you sell before a bond matures or own a bond fund whose holdings are valued in the market. A U.S. government guarantee of timely coupon and principal payments at maturity does not guarantee the price you could receive by selling an individual bond early, as the SEC explains in the same bulletin.

Review your plan before changing holdings

Start with the reason the portfolio exists, when you expect to need the money, your cash needs, and how much loss you can tolerate. Those factors—not a rate headline or recent performance by itself—should guide your asset allocation. The SEC’s Beginners’ Guide to Asset Allocation, Diversification, and Rebalancing explains how goals, time horizon, and risk tolerance inform allocation decisions.

  1. Write down the purpose and time horizon. Note upcoming withdrawals or other cash needs that may affect how much volatility you can accept.
  2. Compare current holdings with your target. Review stocks, bonds, and any other asset classes against the allocation you selected for your plan.
  3. Ask whether circumstances changed. A changed goal, financial situation, or tolerance for risk may justify revisiting the target. Market movement alone does not necessarily mean the target should change. Investor.gov’s Asset Allocation and Diversification guide also connects allocation choices to goals and risk tolerance.

Check the interest-rate sensitivity of your bond exposure

Look at maturity or duration, credit quality, and concentration across individual bonds and bond funds. Similar bonds with longer maturities generally have greater interest-rate risk than shorter-maturity bonds. Duration is another measure of how sensitive a bond or fund may be to interest-rate changes; it is useful for comparing exposures, not for identifying one universally correct portfolio. See the SEC’s bond-risk bulletin and Vanguard’s Learn more about interest rate sensitivity.

Putting more emphasis on shorter-term bonds can reduce interest-rate sensitivity, but it can also mean giving up some income available from longer-term bonds. Bond choices also involve credit risk, liquidity, intended holding period, and possible taxes and transaction costs. Treat these as trade-offs rather than as a ranking of options; current yields and your circumstances matter.

Rank #2

For a bond fund, review the fund’s holdings and duration alongside your own time horizon. A fund’s market value can fall when rates rise, and unlike an individual bond held to maturity, a fund does not have one maturity date at which you receive a particular bond’s principal repayment.

Choose a rebalancing rule and follow it

Rebalancing brings a portfolio back toward its chosen allocation after market moves cause holdings to drift. Vanguard’s Rebalancing your portfolio describes calendar-based reviews, threshold-based reviews, or a combination. Vanguard summarizes the purpose this way: “Rebalancing isn’t about market-timing; it’s about sticking to Vanguard’s principles for investing success and creating a strategy to stay in sync with your long-term goals.”

  • Calendar review: Check on a schedule you can maintain, such as at set intervals, and rebalance if the allocation has drifted enough to warrant action under your plan.
  • Drift threshold: Set in advance how far a holding may move from its target before you rebalance. This makes the trigger depend on allocation drift rather than a rate forecast.
  • Combined approach: Review periodically and act when a holding has crossed your chosen threshold.
  • Use cash flows where practical: Direct dividends, interest, or new contributions toward underweighted asset classes before selling holdings.

These are process options, not prescribed intervals or thresholds. Choose a rule that fits your plan and can be applied consistently.

Account for taxes, fees, and holding-period risks before trading

Rebalancing can involve transaction fees and tax consequences, so consider them before placing trades. Selling an individual bond before maturity can also mean accepting a market price that differs from the amount due at maturity. The SEC discusses costs and taxes in its asset allocation guide and resale-price risk in its fixed-income bulletin.

If your target still reflects your goals and circumstances, use your chosen rule to restore it rather than replacing it with a rate prediction. If those circumstances have materially changed, revisit the allocation itself before deciding how to rebalance. Vanguard’s How to navigate rising interest rates, published April 7, 2025, discusses differing effects across asset classes and cautions against hasty changes when personal circumstances have not materially changed.

What diversification can and cannot do

Diversification can spread exposure across investments, but it does not ensure a profit or protect a portfolio from loss. Vanguard notes this limitation in its rising-interest-rates guidance. The practical aim is to keep the portfolio aligned with your plan and manage risks you can identify—not to make it immune to market moves.

This is general educational information, not a personalized investment recommendation. If you are unsure how your goals, risk tolerance, taxes, or holdings affect an appropriate allocation, consider consulting a qualified financial professional.
