The Fed used repo deals to add cash overnight. Analysts say this hints at deeper US banking stress. The SOFR rate is rising fast. Liquidity is drying up. Another $22 billion came from the New York Fed on Monday. Markets fear cracks in the system. The word “credit crunch” is back. Echoes of 2008 are getting louder.
