Improving Liquidity in the Treasury Market

The Treasury Department’s initiative to boost its purchases of long-term government debt is starting to show some positive effects on liquidity in the bond market. Interestingly, this shift hasn’t stopped yields from adjusting to economic realities, even if the actual buying won’t commence for a few weeks.

Last week, Treasury Secretary Scott Bessent revealed plans to, at the very least, double the buybacks of longer-dated securities. Since then, Treasury bonds have done better than interest-rate swaps that have similar maturities. Notably, the difference between the 30-year Treasury yield and its corresponding swap rate has shrunk to the smallest margin since February, as first reported by Bloomberg News.

This trend suggests that the planned purchases could be lowering the extra yield that investors usually look for when buying and trading Treasury securities. It doesn’t seem to create a formal ceiling on long-term interest rates, which is insightful.

Interest-rate swaps give investors a way to engage with either fixed or floating rates without actually owning government bonds. So, by comparing swap rates to Treasury yields, it becomes easier to differentiate between general long-term interest-rate risk and those changes that are tied more specifically to the Treasury market.

There are certain factors unique to Treasuries that come into play—like the availability of specific securities, the capacity of dealer balance sheets, and the relative challenges of financing or selling older bonds. When Treasuries perform better than swaps, it often signals that investors are asking for less compensation for these market frictions.

A recent analysis from Bank of America supports this view, suggesting that the Treasury’s new policy will likely have more reliable effects on relative-value measures rather than direct yields. Their rates strategists noted a more sensible approach for positioning in light of the increased purchases is to focus on the narrowing of the 30-year swap spread, rather than broadly anticipating a drop in long-term rates.

Bank of America estimates that this policy could ultimately provide about six basis points of support to the 10-year yield if sustained through the end of 2028, though they project only around one basis point of effect through the end of this year.

The Treasury is primarily targeting older, less frequently traded securities, which are often referred to as off-the-run bonds. By giving investors and dealers a consistent way to engage with these securities, the buybacks have the potential to decrease market fragmentation, lighten dealer balance sheets, and enhance overall trading within the Treasury market.

This program is quite different from yield-curve control, where a government or central bank commits to maintaining a specific interest rate by purchasing whatever amount of securities necessary. The Treasury hasn’t set any yield ceiling nor made any unlimited commitments to buy bonds.

Long-term yields are still reacting to various factors, such as inflation data, oil prices, economic reports, and expectations regarding Federal Reserve policies. Following the announcement from the Treasury, the 30-year yield initially dropped, then bounced back to nearly its prior level, before falling again, hovering around 5.2 percent on Wednesday.

This behavior illustrates that the market still plays a key role in establishing long-term rates. Moreover, the ongoing improvement in Treasuries compared to swaps implies that the purchases might be lessening some of the liquidity premium inherent in government bonds.

The government’s financing needs remain unchanged. The Treasury is continuing to issue new securities while simultaneously retiring older bonds through these buybacks. This process essentially swaps out a fragmented assortment of older debt for larger, more liquid benchmark issues.

All in all, the emerging evidence from the market suggests a modest uptick in the operation of the Treasury market. While long-term rates are influenced by economic and financial situations, it seems investors are now seeking slightly less compensation for the challenges involved in holding and trading Treasury securities.
