What is Cantillion Effect?
The Cantillon Effect refers to the change in relative prices resulting from a change in money supply. The change in relative prices occurs because the change in money supply has a specific injection point and therefore a specific flow path through the economy. The first recipient of the new supply of money is in the convenient position of being able to spend extra dollars before prices have increased. But whoever is last in line receives his share of new dollars after prices have increased. This is why when the Treasury’s deficit is monetized, inflation is referred to as a non-legislated tax. In these cases, the government has seized purchasing power (rather than physical bills) from its citizens without congressional approval.

In a vacuum, monetary inflation means
everyone who is holding the affected currency gets poorer. This analysis is tempting for Bitcoin investors who believe it will catalyze higher BTC prices. However it's not that simple.
There are two different issues at play: money supply inflation vs. economic deflation. The global economy is collapsing, running way under productive capacity with record high inventories, as job losses mount everywhere and consumer confidence plunges. This should have a significant deflationary effect on prices, causing them to fall. The economic stimulus is an attempt to hold them up.
No matter how much they inflate the money supply right now, it may not outweigh the effects of economic deflation.
