Asset Allocation Bi-Weekly: Tackling Long-Term Interest Rates

In his testimony before the House Financial Services Committee on February 12, Federal Reserve Chair Powell was questioned about why mortgage rates had not declined. In response, Powell emphasized that the Fed primarily influences short-term interest rates, not the longer-term rates such as those tied to mortgages. Despite the central bank cutting its benchmark short-term interest rate — the fed funds rate — by 100 basis points since September 2024, the average 30-year fixed mortgage rate has risen by about the same amount, highlighting a disconnect between the two.

This apparent discrepancy stems from the fact that most interest rates are closely linked to movements in long-term US government bond yields. While average short-term rates, which are largely influenced by the Fed, have remained relatively stable in recent months, the yield on the 10-year Treasury note has picked up.

This widening gap between short-term rates and long-term rates, often referred to as the term premium, is an important element for understanding today’s interest rate dynamics (the chart below shows the San Francisco FRB’s estimate of the term premium, which uses expected short-term rates versus the 10-year Treasury yield). The growing gap signals that investors are not relying solely on the Fed’s guidance when valuing assets. This may explain why Treasury Secretary Bessent has emphasized that the administration will focus on reducing 10-year Treasury yields rather than pressuring the Fed to lower its policy rate.

Estimated Term Premium

Closing the gap between long-term and short-term interest rates over the next decade will likely be crucial for the administration to reduce borrowing costs effectively for households. This gap represents the premium that investors require to offset risks such as rising bond supply, inflationary pressures, and potential default concerns. To address these challenges, policymakers have proposed a mix of conventional and unconventional strategies.

One conventional approach the administration has taken to help reduce longer-term rates is addressing the US debt problem. The incoming administration has focused on trimming government staffing, reviewing payment systems, and proposing budget cuts to social programs as well as potential cuts to defense spending. On the revenue side, proposed measures include closing tax loopholes, such as the carried interest deduction and special tax breaks for sports teams, while also introducing tariffs to generate additional income.
