Here I found a children's game for you to help you understand why WTI will reach $130+ this year. And I'd you're concerned about sources, it's from the San Francisco Federal Reserve:

Okay now the key parts, our current Federal Funds rate is 0.00-0.25, and has been since Dec '08 and will be until 2014 (probably forever though). So that's 4 quarters and 6 years, for 24 quarters play the game using that ZIRP and our own Federal Reserve's education game tells us what about where inflation will be?
