It's obvious that China has used their tremendous industrial and manufacturing capacity to increase employment and sustain the mandated GDP target of the government. The following comment, "Growth in China, the biggest user of everything from copper to cotton to coal, will slow to 8.5 percent this year, from 9.2 percent in 2011, the mean of 14 estimates shows" comes from a Bloomberg article discussing commodities. China is the largest customer of Australia, Brazil and other economies, including neighbor South Korea. The economy of South Korea provides an indirect window to their primary trade partner, China. The Kospi is a South Korean stock exchange and coincident proxy of economic change in China. It appears that the Kospi was hit hard in the beginning of August when Greece's debt default, and associated threat to the European banking system, became a reality. Prior to and since then, the trend has been slightly positive change.

Commodity markets are generally priced in US dollars. The dollar strengthened in September, hurting buyers of commodities, a condition that repeated in November and December. If the dollar is strengthening, then commodities will become more expensive and that will be inflationary on prices of goods and services. A sideways trend would provide some unexpected currency stability. A weaker dollar would be welcome relief for commodity buyers and relieve concerns about inflation, as well as supporting prices of many stocks and precious metals. The 10 week moving average (gold line) illustrates a strengthening in the trend. The Fed FOMC is not likely to allow a sustained strengthening move in the dollar index without intervening. What if they do allow it? That will signal risk-off and a move to perceived safety.
