Well, a couple things happened "recently" (even major news takes time to hit) to cause people to question the fiat currencies and possibly invest more in Bitcoin.
-FED meeting notes released, markets weren't too happy that some members were suggesting scaling back continuing purchasing of assets
-U.S. budget was actually cut, and the cut so far appears to be permanent although small, signifying lawmakers are running out of choices
-Obama pushing forward with Keystone XL, which is being called upon by lawmakers as a job-creating measure although the projected job stats are hilariously shady. The administration has previously delayed this approval. What this might signify is that Obama's faith in Helicopter Ben to create jobs via QE is waning.
TL;DR: Fed notes indicate less QE in future, U.S. budget was cut, and Obama potentially showing less faith in FED to create jobs and turning to private sector. This can be interpreted to mean bad news for the dollar. $$

So, now add that to the good bitcoin-related news which we seem to have been swimming in for the past couple months.

BTCBTCFolks have a reason to leave the dollar, and a reason to hook up with bitcoin. Hence, price jump. Q.E.D.
