US government bonds are no longer the "safe" investment they once were. SVB didn't hold toxic mortgages or other "risky" debt. They held US bonds, some of the worst investments to be had the past few years. The "safe" half of my portfolio is also in pain. Been there, doing that. Except I have time to let the ship right. Eventually the interest rate my bond fund kicks out will rise to the level of inflation and when that happens, the value of my bonds will rise back to their natural levels. SVB didn't have that time. Game over.
