T-bill yields plunging again

Have things stabilized? If so, someone better tell the short-term Treasury bill market. Once again, T-bill yields are tanking -- a sign of risk aversion. Three-month T-bill yields are plunging, for instance, by 112 basis points to 2.55% recently from 3.665% on Friday and 3.765% on Thursday. Bloomberg just ran a headline saying this is the biggest one-day plunge since the stock market crashed in October 1987.
