JPMorgan Warns US Treasury: Bond Buyback Program Risks Market Credibility

The US Department of the Treasury's plan to implement a bond buyback program aimed at bolstering market liquidity has triggered an unexpected credibility debate at the heart of the global financial system. According to strategists at JPMorgan Chase & Co., this move, rather than solving structural issues in the sovereign debt market, could raise questions about the Treasury's control over borrowing costs and market dynamics.

Liquidity Injection or Price Manipulation?

The move, which aims to enhance financial market depth, specifically targets older, low-liquidity (off-the-run) bonds in the $20 billion to $30 billion range. However, JPMorgan analysts warn that the Treasury overstepping into a market-making role could distort free-market pricing mechanisms.

■Significant contractions in daily trading volumes highlight a persistent loss of market depth.

■Launching the program while the federal debt limit hovers near the $31.4 trillion ceiling exacerbates timing risks.

■This step, conflicting with the Federal Reserve's quantitative tightening (QT) program, sends mixed signals to the market.

Fragmentation Risks on Global Borrowing Costs

The Treasury's artificial flattening of the yield curve through buybacks could directly impact the banking sector's funding costs. In particular, the valuation of high-quality liquid assets (HQLA) held on commercial banks' balance sheets may face a new wave of volatility due to these interventions.

At a time when global central banks are on a tightening path, such liquidity supports from the fiscal policy side run the risk of being perceived as "stealth easing." As a former banker, I can clearly see that this move by the US Treasury will exert indirect pressure on banking sector reserve requirements and commercial lending appetite. Instead of funding liquidity through artificial means, the market mechanism must be allowed to find its own equilibrium; otherwise, macroprudential balances could deteriorate further.
