Odaily Planet Daily News: Documents show that a few months before the closure of Silicon Valley Bank in the United States, the bank's chief risk officer resigned without reason, leaving the position vacant for 8 months. The report quoted documents from the U.S. Securities and Exchange Commission as saying that in April last year, Silicon Valley Bank's then-chief risk officer Laura Izurieta resigned without reason. During her tenure, Izurieta presided over bond purchases and sold approximately $4.18 million in company stock in December 2021. She later reached an agreement when she left and took away more than $7.15 million. Since then, as the Federal Reserve has aggressively raised interest rates many times and continued to raise interest rates, the bonds invested by Silicon Valley Bank using depositors' deposits have continued to depreciate, and were eventually closed by financial regulators on March 10 this year.
