The BEA released the end-2007 International Investment Position data on June 27. Several observations: As in recent years, the NIIP to GDP ratio continues to deteriorate. However, the NIIP to GDP ratio as of end-2007 is improved relative to the originally reported end-2006 NIIP/GDP ratio. In the last year, the dollar change in the NIIP deviates substantially (i.e., is more positive) than the corresponding current account reported on a NIPA basis. This repeats the pattern from the previous five years. Interestingly, 2005 stands out by far as an outlier, wherein the the NIIP improves while the CA is in substantial deficit. There appears to be a measurable correlation between dollar depreciation against other major currencies and the deviation between change in NIIP and CA.
