US Treasury's Bond Market Intervention Proves Fleeting as Yields Rebound

The U.S. Treasury's efforts to stabilize the bond market through expanded buybacks of long-term Treasury bonds appear to have had a fleeting impact, as yields rebounded shortly after the intervention was announced. On August 20, yields on U.S. government debt, especially the 30-year bond, reversed their earlier decline in Asian trading, erasing the gains made following the Treasury's announcement the previous day to increase buyback operations.

This intervention ignores potential structural challenges and does not take any measures to address the related issues.

The Treasury had announced it would boost its buyback of 10-year to 30-year Treasury bonds from $2 billion to at least $4 billion, spanning from September 9 to November 4. While this move initially pushed the 30-year yield down from a high of 5.337% (the highest since 2007) to 5.187% and the 10-year yield to 4.642%, by midday Eastern Time on August 20, both had climbed back up to 5.236% and 4.696%, respectively.

This rebound highlights the difficulty of market interventions, particularly when numerous factors are driving yields higher. Analysts like Maia Crook from JPMorgan suggest the intervention might be ignoring underlying structural challenges and could potentially lead to higher risk premiums as markets perceive the Treasury's active involvement. Liang Qitang of Kingston Securities noted that increased intervention could prompt institutional investors to sell, likening the Treasury's actions to a company buying back stock only to issue more shares later.

The more the US Treasury intervenes, the more it will trigger institutional investors to sell.

The Treasury's actions also complicate the Federal Reserve's monetary policy decisions. Fed Chair Jerome Powell had previously indicated that rising long-term yields were a welcome development, acting as a de facto tightening of monetary policy without the need for further short-term rate hikes. However, the Treasury's intervention, by attempting to lower these yields, contradicts this market-driven tightening, creating an awkward situation for the Fed and potentially forcing them to consider more aggressive rate hikes to combat inflation.

Powell's situation is very awkward. Previously, the market generally believed that the Federal Reserve did not necessarily have to raise interest rates because the long-term bond market had already done the job for the Federal Reserve, but now the Treasury has overturned that assertion.
