In its not so infinite generosity of spirit, every week the Fed gives us reams of data. Some of that data is quite revealing and quite useful for our purposes. The data helps us to understand the current monetary/liquidity environment, which helps us to understand the context of the current market milieu. That in turn helps us to divine where the market might be headed.
But there are times when the Fed thinks its information might be too helpful to us. So what does it do? It eliminates that item from its data. Poof! Something that had been helpful to us for years no longer exists.
It has happened before, and it just happened again with an item that had been extremely revealing.
Apparently this information had become too useful to us. So, naturally, the Fed made it disappear. Now only the Fed knows about it. Oh, that data is still being collected, but they buried it with several other items into a useless catchall line item.
