Inflation is an increase in money supply which is what is happening today with the number of Bitcoins in production. Eventually it will be deflationary because coins get lost.
Inflation has nothing to do with price volatility. Something that cost 10 Bitcoins yesterday might cost 1 Bitcoin today and 2 Bitcoins tomorrow. It doesn't mean that Bitcoin is deflationary today and inflationary tomorrow.
