What's Going to Affect Commodity Prices This Year?

Chevron CEO Mike Wirth talks to CNN's Lisa Ling about the global economy and oil. He says a strong return to the Chinese economy could help push up commodity prices this year. Chevron hasn't changed where it does some of its drilling or exploration, but has been "nimble" in dealing with short-term logistics issues. But investors are rewarding companies like Chevron more for investing in production than they did two years ago because of renewed focus on fossil fuels after being left for dead.
