Barclays strategists warn that the U.S. Treasury market's explosive growth to $31 trillion has created structural instabilities that will likely require future government intervention to prevent liquidity crises.
"The U.S. government debt market has grown much faster than the incremental increase in bank capital," a report co-authored by New York University professor Jeffrey Meli and several former Barclays colleagues said. This gap is the "underlying force driving market fragility."
The analysis points to a fundamental liquidity mismatch, where the supply of Treasurys has overwhelmed the capacity of primary dealers to intermediate effectively. This structural issue could increase volatility in Treasury yields, the benchmark for global finance.
At stake is the stability of the global financial system, which relies on a liquid and orderly Treasury market. The report suggests that without a plan for official intervention, it's impossible to maintain market stability while avoiding government bailouts.
The report from Barclays highlights a reversal of decades-long trends, where the sheer scale of government debt issuance now dwarfs the ability of market-making banks to absorb it. This imbalance between the supply of government debt and the demand for liquidity from intermediaries is a critical vulnerability.
This structural fragility has manifested in several recent episodes of market stress. The report implies that events like the September 2019 repo market crisis and the March 2020 "dash for cash" are not isolated incidents but symptoms of this deeper problem.
The potential consequences are systemic. As the bedrock of the global financial system, any dysfunction in the Treasury market can cascade across all asset classes. Increased volatility in benchmark rates could disrupt everything from corporate borrowing costs to mortgage rates and international capital flows.
The authors argue that the current market structure is unsustainable without a clear backstop. This puts pressure on regulators and the U.S. Treasury to consider new facilities or frameworks to provide liquidity during times of stress, effectively institutionalizing the need for periodic government intervention.
