The yield on the 10-year U.S. Treasury recently crossed 5%, a level that has attracted plenty of attention in the financial media. That makes sense. Five percent is a memorable number.

From an investment perspective, though, there is nothing magical about 5%.

Interest rates matter. Changes in rates affect borrowing costs, bond yields, business decisions, and the broader economy. But a Treasury yield crossing an arbitrary round number does not suddenly make the information more useful for making investment decisions.

The better question is whether anything about the current interest-rate environment should cause us to change the way we invest.

We don’t believe it should.

Bond markets are forward-looking. Before the Federal Reserve’s most recent rate increase, Treasury yields had already moved higher as investors increasingly expected the Fed to act. When the Fed finally announced the increase, relatively little happened to yields because the market had already anticipated the news.

More importantly, every dollar in a portfolio has a job. Stocks are primarily responsible for long-term growth, while bonds tend to preserve capital and insulate portfolios from large stock market swings.

Higher rates don’t change that job. In fact, higher yields generally improve the return potential of bonds going forward. Earning a little more from the part of the portfolio designed for stability isn’t a bad outcome.

Higher interest rates are frequently presented as bad news for stocks because they increase financing costs. But the relationship isn’t nearly that simple. The Federal Reserve often raises rates when economic conditions are strong and cuts them when economic conditions weaken. These competing narratives – higher financing costs versus a strong economy – make it difficult to predict if rising rates might be good or bad for stocks. Market participants make this evaluation every day and reflect those expectations in stock prices.

Rather than trying to decide which story sounds better, let’s study the data.

We looked at the historical record of US stock market returns and interest rate changes from 1979 through 2025, then we separated calendar years based on whether the 10-year Treasury yield rose or fell during the year.

The results are remarkably similar.

In years where rates increased, US stocks delivered an average return of 11.9%. In years where rates decreased, the average return was 11.6%. A difference of just 0.3%.

The takeaway is not that rising rates are good or bad for stocks. It is that markets incorporate expectations about changing interest rates into stock prices. Investors don’t need to predict the direction of rates to capture the long-term returns stocks are expected to provide.

Rising rates do not spell doom for stocks, nor do they provide a reason to change a well-designed financial plan. Historically, the direction of interest rates has told us very little about future stock market returns.

For investors, there is no special significance to the 10-year Treasury yielding 5% instead of 4.9%. It is a round number that makes for an interesting headline, but it doesn’t change the role of stocks or bonds in a well-designed portfolio.

Bonds still have the same job in our portfolios: preserving capital and dampening stock market swings. Higher yields simply allow them to earn more while doing it.

Our stock investments remain the portfolio’s primary source of long-term growth. Nearly five decades of market history give us little reason to treat rising interest rates as a useful signal about future stock returns.

Financial headlines will change. Round numbers will come and go. The principles behind a well-designed investment plan don’t change with them.
