After Silvergate, SVB is the 16th largest bank in the U.S. and the next financial company to run into trouble last week. The Silicon Valley-domiciled bank is also primarily a link between venture capitalists and startups. The institution has grown rapidly since the liquidity glut in the wake of the pandemic. Some of its capital has been invested in default-proof long-term U.S. government bonds, which have yielded low but safe interest rates in recent years. As a result of the Fed's tighter monetary policy to combat inflation, yields on these bonds have risen and, accordingly, their value has fallen significantly. To avoid having to show this as a price loss on the balance sheet, a banking institution can carry its bonds at nominal value. As a rule, the bonds are held until maturity and repaid accordingly at 100%.
