Steno argues that Kevin Warsh wants to shrink the Fed balance sheet, but cannot do so without causing a liquidity crisis in the repo market (as seen in Q4). The only way to shrink the Fed balance sheet safely is to allow private banks to take on more leverage. This requires rolling back post-2008 regulations, specifically the Supplementary Leverage Ratio (SLR). Steno predicts this easing will free up "trillions" in capacity. A rollback of leverage constraints allows banks to expand their balance sheets and profitability, creating a massive tailwind for the financial sector. If the administration fails to pass regulatory easing, the Fed cannot shrink its balance sheet without breaking the repo market.
