I am honestly not looking to criticize him… Paul Krugman wrote a lot back in 2008 about the lack of a speculative signal in the oil markets. (Specifically, inventories weren’t rising and production wasn’t falling, so the record prices in the summer were due to “fundamentals” he thought.)
But I seem to recall that this time around–say within the last 6 – 8 months–he wrote that he thinks speculators might be involved with the rapid increase in oil prices, because now there is evidence of accumulating inventory.
However, I can’t find his more recent post(s) on this. Any help?
