According to Golden Finance, U.S. Treasury Deputy Secretary Michael Faulkender said officials are discussing a possible rule change for banks. As U.S. bonds fell last week, the regulatory ruling "supplementary leverage" (SLR) has attracted a sharp rise. The biggest drop in more than two decades hit by U.S. bonds has raised concerns about a market crash similar to that in March 2020. Any change in the rules still requires approval from the Federal Reserve and other regulators, although the chairman of the regulatory committee responsible for U.S. financial stability is the Treasury Secretary. "We are investigating this matter and have begun discussions," Faulkender said at an event.
