Oil is climbing again today as investors increased bets on rising prices following Saudi Arabia's confidence that crude will rebound as global economic growth boosts demand. Blaming the fall in oil prices on speculators and the lack of cooperation from non-OPEC producers, Saudi Arabia also announced that it would not cut output even if non-OPEC nations did so. Brent crude is up 1.2% at $62.13/bbl. WTI is up 0.9% at $57.64.
