What Do Changing Interest Rates Mean for My Bond Investments?

What Do Changing Interest Rates Mean for My Bond Investments?

This past week I got several emails from clients about bond investments. Although warranted by the headlines bonds have seen recently, it was a bit surprising. Why? It's a first. Bonds tend to be on the "boring" side of the investment spectrum and don't generate a lot of buzz. Over the weekend at a wedding in San Diego, I once again had several people ask me about bonds among some other financial topics. The questions about SpaceX, and tariff economics were expected, but once again this focus on bonds was a first. For years, investors viewed bonds as a low-risk option for their portfolios. Does this still hold true, even with the recent history of 2022's bond carnage, or are these news headlines onto something and bonds are losing their boring?

In this article we'll explore:

• The rules that govern bond price movement. (The relationship between bond prices and interest rates)
• What economic and financial factors are impacting bond prices in today's world.
• Some historical context for where interest rates are today.
• What this means for your investments.
• Covering what action if any investors should be taking.

And although unlike the bond analysis, it wasn't asked for, here is a photo of my wife and I from the San Diego wedding!

Why Do Bonds Fluctuate in Price?

When interest rates rise, existing bonds lose market value.

A simple way to picture this is to compare a bond to a Certificate of Deposit (CD) at a bank. Suppose you buy a 5-year CD that pays 4% interest. If overall interest rates subsequently rise and banks begin offering the same 5-year CD paying 5%, nobody will pay full price for your 4% CD. To sell it before maturity, you would have to discount the price so the buyer receives an effective return equal to the new 5% market rate.

The inverse is also true. If rates fall to 3%, your 4% CD becomes more attractive. Demand increases, and you could sell it at a premium above its original face value.

This inverse mechanics, when yields go up, prices go down, and vice versa, is the fundamental cause of price volatility in fixed-income markets.

What Is Causing Interest Rates to Rise Today?

Interest rate movements reflect a complex interplay of economic growth, inflation expectations, and market supply. Five primary macroeconomic forces are putting upward pressure on bond yields:

1. Persistent Inflation & Energy Shock Concerns
Inflation erodes the real purchasing power of a bond's fixed income payments. Recent geopolitical friction in the Middle East has caused energy prices to spike, raising concerns that inflation could remain sticky above central bank targets. Investors demand higher nominal yields to offset this inflation risk.

2. Central Bank Policy & "Higher for Longer" Expectations
Short-term yields closely track the interest rates set by the Federal Reserve and other global central banks. When central banks signal that borrowing rates may remain elevated to cool inflation, newly issued bonds carry higher rates. Investors reallocate out of older, lower-yielding bonds, lowering their prices.

3. Record Government Debt & Treasury Supply Overhang
As governments issue historic volumes of debt to fund spending deficits, the rules of supply and demand take hold. To attract sufficient money to absorb trillions in new Treasury bonds, interest rates must rise. Expanding national debt loads also lead investors to demand a higher "term premium" to hold long-duration bonds.

4. Massive Corporate AI & Infrastructure Issuance
Beyond government debt, major technology firms are issuing record volumes of investment-grade corporate bonds to finance large-scale artificial intelligence infrastructure, data center expansion, and power capacity. This massive inflow of corporate bonds competes directly with Treasuries for investor capital, putting upward pressure on interest rates across the board.

5. Stronger-Than-Expected Economic Growth
Resilient economic activity dials back market expectations for aggressive rate cuts. Strong corporate earnings and robust consumer spending encourage capital flows into higher-risk growth assets like equities, reducing demand for safe-haven bonds and lifting yields.

Putting Current Yields in Historical Context

To evaluate where fixed income stands today, it helps to look at long-term benchmark levels.

10-Year U.S. Treasury Yield Averages

• 56-Year Historical Average (1970–2026): ~5.85%
• Pre-2008 Historical Average (1970–2007): ~7.60%
• Post-2008 Low-Rate Era Average (2008–2021): ~2.40%
• Current 10-Year Treasury Yield: ~4.79%

While current rates feel exceptionally elevated compared to the artificially suppressed, near-zero environment following the 2008 financial crisis, they remain moderate when viewed across a broader 50-year horizon.

What Does This Mean for Your Portfolio?

Understanding where we were in 2021 versus where we are today highlights why the bond market outlook has fundamentally changed for the better.

1. Understanding the 2022 Drawdown

At the end of 2021, the yield to maturity (YTM) on the Bloomberg U.S. Aggregate Bond Index ("the Agg") was under 2%. When interest rates surged rapidly in 2022, those low-yielding bonds offered almost no interest income to absorb the price decline. Consequently, the Agg suffered a peak drawdown of approximately -18.4%.

2. Higher Starting Yields Provide a Real Buffer

Today, the yield to maturity on broad bond indexes sits near 5%. Starting with a 5% baseline income stream provides a significantly stronger cushion. Even if interest rates rise modestly from here, the higher coupon income actively helps offset potential price declines—a protective barrier that simply did not exist three or four years ago.

Strategic Action Steps: What Should Investors Do?

Navigating today's fixed-income landscape requires balancing short-term liquidity with long-term portfolio protection.

1. Maintain a Strong Cash & Short-Term Reserve

We consistently recommend maintaining an adequate liquidity buffer in money market funds, high-yield savings, and short-term bond funds. Short-term bonds carry lower sensitivity to interest rate fluctuations (low duration risk), making them a better vehicle for capital preservation and short-term spending needs.

2. Do Not Abandon Longer-Term Bonds

While short-term yields are attractive, moving completely away from intermediate and longer-term bonds can be a costly mistake. Intermediate and long-duration bonds offer essential portfolio diversification, often when needed most during equity market sell-offs.

• 2008–2009 Financial Crisis: As stock markets declined sharply, long-term Treasuries surged as capital sought safety and central banks slashed rates, providing critical stability to diversified portfolios.
• 2020 Pandemic Shock: During the sudden equity drawdown in early 2020, long-term bonds again served as a major shock absorber.

If economic growth slows or the economy enters a recession, long-term bond yields often fall, driving price appreciation that can help to offset stock market losses.

3. Rebalance and Lock in Higher Rates

If short-term cash rates eventually decline, short-term yields will fall quickly. Rebalancing portfolio allocations into intermediate and longer-term bonds allows you to lock in today's attractive income yields for years to come, securing reliable cash flow while reinstating your portfolio's primary defense against future stock market volatility.

As with any investment decision, fixed-income allocations should align with your broader financial plan, tax situation, and risk tolerance. Reach out to our team to discuss how your specific bond portfolio is structured for today's interest rate environment.
