Some people think deficits cause inflation; some don't. I'm in the latter group, because I think inflation is almost always a result of monetary policy, and seldom if ever of fiscal policy.
But whichever it is, the numbers should start swinging one way or the other reasonably soon, given the unprecedented deficits we're running (...and will continue to run for several years). Either deficits will pull away from the low inflation numbers, or the inflation numbers will start rising with the deficits. It might be a good idea to start watching all the key numbers in one place on a regular basis, so here they are:
The CPI says we're deflating; the other three say we are safely in low-inflation territory.
Another way of saying that: all four indicators say that inflation is not a problem yet. Neither the deficits we have, nor the deficits we know are coming, nor the trillion dollars the Fed has "printed up" are causing any inflation so far. Why? In my judgment, deficits don't cause inflation, so that narrows the mystery down to all that money the Fed printed up. Reason that's not causing inflation yet is because almost all of it is just sitting there, in "excess reserves" in the banking system. (If the Fed printed up a *hundred* trillion dollars and set it down in an inaccessible nook at the bottom of the Grand Canyon, that wouldn't be inflationary either.)
So here's this week's conclusion:
============
End note regarding the four inflation indicators I picked:
My two personal favorites are the so-called TIPS spread, and the "trimmed-mean" PCE. The TIPS spread is the worldwide bond market's daily judgment on inflation, and the most popular "spread" is the difference between the interest rate on 10-year Treasury notes and the rate on 10-year Treasury inflation-protected securities. The trimmed-mean PCE is the Dallas Fed's massaging of the components in the personal consumption expenditures numbers, and it's a second cousin of "core" PCE.
The Consumer Price Index (CPI) is a must have because it's always in the headlines. The GDP deflator is a bit more comprehensive than the others, but it's also more delayed (...it's more of a rear-view-mirror indicator).
