Forecasting index values requires an inflation term structure. The inflation term structure (ITS) defines the usual lag (not the index). I.e. an ITS is always relatve to a base date that is earlier than its asof date. This must be so because indices are available only with a lag. However, the index availability lag only sets a minimum lag for the ITS. An ITS may be relative to an earlier date, e.g. an index may have a 2-month delay in publication but the inflation swaps may take as their base the index 3 months before.
