Content: Is China cooking its books? Supply glut, dollar strength: The poor demand is being exacerbated by too much supply. The commodities boom, fueled by China's explosive growth in previous years, caused energy and metals companies to ramp up production to levels that today's market just can't support. Look at how North American oil producers pumped so much oil out of the ground that now there is a huge supply glut. And then there's the U.S. dollar. Because the American economy looks better than its peers and the Federal Reserve has stopped its stimulus program, the greenback has raced ahead of rival currencies like the euro and the yen. That's bad news for commodities because most of them are priced in dollars. A stronger greenback depresses demand by making oil and other natural resources more expensive to buy in other currencies.
