During the hearing, Tabacchi highlighted:

• The critical role of independent dealers in providing liquidity, especially during periods when large bank-affiliated institutions face balance-sheet constraints.
• The importance of a more diversified and resilient Treasury market, including consideration for broader participation in the primary dealer framework.
• The need for expanded access to tools such as the Standing Repo Facility, which can enhance the stability and efficiency of Treasury funding markets.

• “The Independent Dealer and Trader Association (“IDTA”) appreciates this opportunity to testify before the Task Force on Monetary Policy, Treasury Market Resilience and Economic Prosperity on the Primary Dealer program and how well it is operating to achieve robust liquidity for the US Treasury securities and Repurchase Agreement (“Repo”) markets.”
• “As a group of middle-market firms, we have seen a reduction in competition in these markets and an increase in concentration of risk over the last several years.”
• “IDTA members are often countercyclical providing liquidity and balance sheet capacity at times when the largest systemically important financial institutions (SIFIs) have balance-sheet constraints during certain times of the year (e.g., quarter end).”
• “Non-bank independent broker dealers are not as constrained by balance sheet considerations during these periods of stress … Independent broker dealers are both willing and able to provide liquidity in these scenarios and can help prevent bottlenecks in funding in the Repo market.”
• “It therefore does not seem like a bold suggestion that the US Treasury and FRBNY should expand the Primary Dealer program to include more non-bank registered broker dealers.”
