You're reasoning from a price change. Inflation is flat/decreasing only slightly because of the "printing", otherwise it would be sharply downwards.

The fed is engaging in aggressive monetary policy to prevent deflation.

The suggestion that buying corporate bonds (while holding everything else constant) is not inflationary is just not right. You can hold on to your mistaken beliefs, but just know that if you do so, it is in willing ignorance of the facts.
