I stopped updating this because it was so boring (which was kinda the point in the first place), but here’s the updates since September 2009 …
For those who have alt-A or Prime ARM loans tied to the 12-month LIBOR + 2.25% margin (rounded up to the next 8th).
Sept-Dec 2009
September 12-month LIBOR : 1.26%
fully-indexed ARM reset RATE : 3.625%
October 12-month LIBOR: 1.33
fully-indexed ARM reset RATE : 3.625%
November 12-month LIBOR: 1.20
fully-indexed ARM reset RATE : 3.5%
December 12-month LIBOR: 1.02
fully-indexed ARM reset RATE : 3.375%
2010
January 12-month LIBOR: 0.98
fully-indexed ARM reset RATE : 3.25%
February 12-month LIBOR: 0.85
fully-indexed ARM reset RATE : 3.125%
Most of these loans had starting rates in the mid 5% range, so they will either go down significantly ort stay the same in cases where there is an interest rate floor.
