Higher copper prices look to be a short-term trend.

"But watch for prices to start coming down, warns BMO Capital Markets in a study released this week. Policy normalization in China in the second half of this year will see reduce frenzied buying for copper and other commodities."

However, I would argue that "reduced frenzied buying in copper and other commodities" will not necessarily translate to lower prices in general (for all goods and services).  There are developing shortages in many types of "soft" commodities such as building materials and coffee, so inflationary pressures on the economy, in general, may not be slowing. 

But what does "inflation" mean anyway?
