It obvious how this happened. Schwab did use a bond ladder. They went all in on the 10 year and 20 year treasuries, using the deposit sweeps. They needed to gradually build up, doing 3 months, 6 months, 9 months, 1 year, 18 months, 2 years, and some 5 and 10 yearers. But noooooooooo. They went all in when the 20 year was a 2.5%. And as the interest rates rise, like the ever high tide rises, the UGL sunk in. Now if they can hold till maturity in 20 years, then as Arnold would say, "no problemo". But they were getting called by the withdrawals. So big problemo. All of a sudden the UGLs became RGLs.
