How the Latest Tax Bill Could Impact Bonds and Your Portfolio

The Tax Bill’s Direction and Deficit Impact

A sweeping new tax proposal is making headlines for its cuts and credits, but there’s a deeper story developing beneath the surface. The resulting shift in government borrowing could have meaningful consequences for bond markets, and by extension, your long-term portfolio strategy.

This week, the House Ways and Means Committee introduced a multi-trillion dollar tax proposal that could have far-reaching effects beyond the headlines. While much of the coverage will focus on the changes to tax laws themselves, less attention is being paid to the impact these changes could have on the federal deficit. The story beneath the surface is how these fiscal shifts may ripple through the bond market, a connection every investor should understand when managing a diversified portfolio in today’s environment.

Although the proposed legislation is still in its early stages, its intent is clear: it aims to deliver significant tax relief through measures such as a higher cap on state and local tax deductions, permanent extensions of the 2017 individual tax rate cuts, an increased standard deduction, and a larger child tax credit. While the specifics will likely evolve as the bill moves through Congress, the overarching theme is unmistakable. The focus is on substantial tax cuts, accompanied by only modest reductions in government spending. This direction, more than any single provision, is what will ultimately shape the fiscal landscape and its downstream effects on the bond market.

Early estimates suggest that the proposed tax cuts would reduce federal revenue by $3.7 trillion over the next decade, while the planned spending cuts would offset only about $1.5 trillion of that amount. As a result, the government’s income will fall much more than its expenses are reduced, leading to a larger deficit. That challenge is nothing new for the U.S. fiscal landscape. While deficits have long been a feature of U.S. policy, this legislation is poised to further widen the gap, requiring the government to borrow even more by issuing additional Treasury bonds. This increase in borrowing is a key factor that could influence the bond market in the years ahead.

What This Means for the Bond Market

Understanding the link between government borrowing and the bond market is essential for investors navigating today’s environment. As we’ve discussed previously in Understanding the Treasury Market: A Primer for Investors, increased Treasury issuance means more bonds entering the market. When supply outpaces demand, yields tend to rise, which puts downward pressure on bond prices. This dynamic is especially important for investors to understand, as it suggests that interest rates could remain elevated or continue rising gradually over the coming decade if the government continues to rely on debt to finance persistent deficits. While many factors influence the direction of interest rates, the prospect of sustained, elevated Treasury issuance is a structural force that could shape the bond market for years to come.

Rethinking Portfolio Construction

Given these shifts in the bond market, it’s important to revisit how portfolios are typically constructed. Traditional portfolio construction relies on diversification between stocks and bonds, with the mix tailored to each investor’s risk tolerance. Bonds have long been viewed as the “risk-off” component, providing stability and income during equity market volatility. That’s why we’re closely monitoring these evolving dynamics for our clients.

With the potential for higher yields and increased volatility, investors may want to consider strategies that help manage interest rate risk. These could include favoring short-duration bonds, incorporating Treasury Inflation-Protected Securities (TIPS), or exploring alternatives such as dividend-paying equities or gold. The ongoing imbalance between Treasury supply and demand could continue to drive rates higher, introducing new risks to traditional bond holdings and underscoring the importance of thoughtful portfolio construction.

Where appropriate, we also consider the tax placement of fixed income holdings across taxable and retirement accounts. Aligning these decisions with a client’s overall tax picture can help reduce the drag of interest income and improve after-tax returns.

Preparing for What’s Ahead

As we look to the future, it’s clear that the debate over tax policy will continue to have significant implications for the bond market and your portfolio. In an environment where government borrowing shows no sign of slowing, now is the time to review your bond holdings and broader portfolio to ensure you’re prepared for the shifting landscape ahead.

Sticking with a portfolio structure that made sense five or ten years ago, without adjusting for today’s interest rate and fiscal environment, could lead to unnecessary risks or missed opportunities. A well-timed review now can help ensure your strategy remains aligned with both market conditions and your personal goals.

Frequently Asked Questions

How do tax cuts affect the bond market?

Tax cuts that aren’t matched by equivalent spending reductions usually increase the federal deficit. To cover the shortfall, the government issues more Treasury bonds. That added supply can push interest rates higher, which in turn affects the prices of existing bonds and the overall return investors earn on fixed income holdings.

Why does bond pricing move when yields rise?

Bond prices and yields move in opposite directions. When new bonds offer higher interest payments (yields), existing bonds with lower rates become less attractive, so their prices drop. This is especially relevant when inflation or government borrowing drives rates upward.

What types of bonds are less sensitive to rising rates?

Short-duration bonds tend to be less affected by rate increases because they mature sooner and can be reinvested at higher yields more quickly. Treasury Inflation-Protected Securities (TIPS) and floating rate notes are other options that may help manage interest rate risk.

Should I still hold bonds in a rising rate environment?

Yes, but it’s important to be selective. Bonds still serve as a source of income and risk management, especially during equity market volatility. The key is adjusting the mix, favoring shorter durations, diversifying across sectors, and aligning holdings with your time horizon and tax situation.

Can we grow our way out of the national debt?

It’s a reasonable idea in theory. Strong economic growth can help increase tax revenue without raising rates. But in practice, the U.S. has continued to accumulate debt even during periods of expansion. Without changes to spending or revenue policy, growth alone is unlikely to close the gap. This reinforces the importance of understanding how rising debt levels may affect interest rates, inflation, and long-term bond performance.
