Paul Krugman in NYT explains the failure of Silicon Valley Bank. He says the bank invested its money in safe Treasury bonds which fell in value with Fed's policy of sharp increase in interest rates to fight inflation. It presented itself as the bank for people in Silicon valley and succeeded more than it imagined possible leading to these investors putting their money at SVB bank. However Krugman points out SVB bank did not put this money from deposits into startups, it put these deposits in safe US Treasury assets. It is Venture Capital that put its money in the startups at Silicon Valley, then panicked and set in motion a bank run that led to $42 billion withdrawals on one day Thursday March 9. These SVB assets have value says Krugman. Over time the government says Krugman will get much of its money back from these Treasury assets of SVB. 

Then why the government rescue by president Biden? A bank run of this type undermines confidence in other regional banks affecting the US banking system in a way that is totally unnecessary when the banking system as a whole is safe. In fact the Fed vice chairwoman Lael Brainard understood and made clear these risks says Krugman, and she now heads Biden's national Economic Council.
