They are absolutely correct. The velocity of money is still decreasing.
This is a chart of the total consumer credit outstanding through 02/28/2010.
Consumers are still decreasing their credit lines and living in their means, a tiny bit more, but it appears to be a trend that may continue.
Here's a view of the consumer revolving credit owned by commercial banks, which is included in the data above, but in this graph that data is presented separately through 02/28/2010.
Here is a view of total consumer loans owned by commercial banks, which is also included in the data from the first graph, through 02/28/2010.
This is the data for real retail sales and food service sales through 03/01/2010
While it has been rising lately it is still well below its high.
And finally this is the data for savings deposits through 03/01/2010. I wanted to post personal savings rate but can't find anything that has been updated since 10/2009.
Bottom line is that consumers are spending less and banks are lending less and savings are increasing. It is impossible to inflate if money does not start flowing out faster than it is printed. The time will come, but it's not here yet.
