This isn't your typical peak oil nut job. The world's second largest bank is warning that there could be as little as 50 years of oil left.
The senior global economist at the world's second largest bank warned that the global oil supply might run out in under 50 years.
"Energy resources are scarce," wrote Karen Ward, HSBC's senior global economist in a research report that was obtained by CNBC. "Even if demand doesn’t increase, there could be as little as 49 years of oil left."
