Silicon Valley Bank (SVB), a unit of publicly traded SVB Financial Group, was the go-to bank for the venture capital (VC) economy, where it had 50% market share and was growing rapidly. Nearly all its deposits were from these VCs and tech-related firms, which is an unusual level of depositor concentration. Because so many depositors were commercial enterprises, nearly 90% of these deposits were uninsured (above the $250,000 limit from the Federal Deposit Insurance Corp.). SVB’s deposits increased at an extraordinary rate over the last few years because of high levels of start-up tech funding and money flooding into private equity. The bank deployed 70% of that cash into fixed-rate, low yielding bonds (mostly Treasuries and mortgage-backed securities).
However, that dynamic reversed abruptly in the past year, as the bank’s clientele burned through cash at a higher-than-expected rate, quickly reversing the deposit growth. SVB opted to sell some of their bonds to raise cash, then raise capital, and reinvest the cash at higher rates. However, SVB’s situation worsened because of the optics of selling the bonds at a loss before raising capital. When the stock fell 30% in response, some VC firms began advising clients to pull deposits, which created a classic bank run. An additional $42 billion in deposits was pulled out Friday and the FDIC stepped in to put the bank into receivership and did the same for Signature Bank on March 12.
While the SVB failure is notable, it is not large enough on its own to create these extraordinary market dynamics. Rather, markets are concerned about a contagion effect, where panicked investors pull money out of other banks, creating a larger systemic issue. In part because of this difficult-to-quantify risk, the Treasury, Fed, and the FDIC announced on the evening of Sunday, March 12 that depositors in SVB would remain whole and have access to their funds on Monday, March 13, funded by the FDIC.
