Internet reports that U.S. Deputy Treasury Secretary Michael Faulkender said officials were discussing a possible rule change for banks. As U.S. debt fell last week, attention to the regulatory requirement "Supplementary Leverage Ratio"(SLR) has soared. The largest decline in U.S. debt in more than two decades has raised concerns about a market crash similar to the March 2020. Any rule changes will still require approval from the Federal Reserve and other regulators, although the Treasury Secretary chairs the Supervisory Committee responsible for U.S. financial stability. Faulkender said at an event,"We are investigating this matter and have already started discussing it."
