FDIC report attributes Signature Bank collapse to mismanagement.

An internal review by the FDIC found that "poor management" led to the collapse of Signature Bank, which pursued rapid, unrestrained growth without developing adequate risk management practices and controls. The bank funded its growth through an overreliance on uninsured deposits without implementing fundamental liquidity risk management practices and controls. The FDIC could have been more forward-looking and forceful in its supervision, while Signature Bank could have been more measured in its growth and more responsive to the FDIC's supervisory concerns.
