The price is rising. Remember, in order to maintain an even price, due to mining, BTC has to beat its built-in 16% inflation. (Admittedly, the dollar is inflating too so it's jelly all around.)
Bitcoin monetary inflation is down to around 11.5% right now, but your point is correct that it is still higher than the base USD inflation, and likely will be until at least the next halving (2017).
I had the same thoughts about that 11.5% inflation when I first look into it... but in later time when I think it again ,I feel nothing should worry about it ,since the fundamental of BTC is about less than 50K of people, it has numerous spacing for its to growth, and assume that 11% of its users base been increase with a year then it will be roughly eliminating the effect of inflation, and from self of view that this 11% increase of users base are 100% will be exceed ,thereby no inflation ,and still deflation.
As BTC is different then Fiats ,fiats relatively have roughly fixed users basis and BTC isn't...We can't compare those two different thing within the same theory.
Sorry for my poor English.
