Cramer warns of bank crisis and calls for government action.

CNBC's Jim Cramer suggests that the Federal Reserve may need to take "desperate measures" at next week's meeting due to the growing banking crisis, which could be "fantastic" for investors' portfolios. The collapse of Silicon Valley Bank and Signature Bank in New York has led to fears of the crisis spreading into Europe, with investors concerned about the future of global bank Credit Suisse. However, it remains to be seen if the Fed's actions will outweigh the negative effects of the crisis.
