Base Metals surprisingly strong

Base metal mining stocks have been weak over the last 3 months - the blue chips having fallen 20- 30%, whilst the smaller emerging producers have fallen as much as 70%. The reason of course is the belief that commodity prices will fall with any softening in the global economy. I think this is sure to happen. At some point the Fed and other central banks will be forced to respond to inflation. Higher interest rates will be necessary. But until then we can expect governments to respond to subdued demand (amidst weak but growing inflation) with cuts or stable interest rates. I think we should not expect the Fed to have some balls. They might correctly sense that a 'dose of reality' will be good for the market, but they will not want to surprise it too much.
So is the sell off in base metal miners and emerging producers justified? I think it depends on the market. There are some strong factors in base metals favour:
1. Demand for metals in China remains strong. I believe Chinese demand will not remain strong. Historically I have found the Chinese traders and producers to be poor market analysts. They are sooo anti-conceptual. Demand has been strong for so long, so they believe it will be strong tomorrow. They would rather be wrong with everyone else than right alone. Chinese traders will be the last to recognise that the market is turning. That augers well for markets in the short term.
2. Weaker markets has a benign impact on domestic commodity markets. If you are a Canadian or Australian investor, you might be miffed by the fall in commodity based mining stocks. Miffed because metal prices remain strong, so why are mining equities being sold off with reckless abandon. The reason is that international investors are preparing for a slump in commodities (apart from gold). Whilst a falling $AUS or $CAN will boost or offset the fallin USD prices of commodities for domestic investors, the international investors will loose on the exchange rate. Expect those foreigners to re-enter the market at lower prices. Of course it makes sense for local (Australian & Canadian) investors to abandon mining stocks if the foreigners are going to, but they should also be ready to buy back in. The trick is to find the turning point in the $A. See my forex blog. So whilst base metals have fallen off slightly (15%), so has the Australian dollar, so producers are actually doing rather well, unless they have entered into some rather unfortunate hedging positions.
3. Tight supply. There is of course a concern in the markets that a slide in global economic activity will undermine demand for metals, and that should not be ignored. But there is also considerable tightness in equipment, plant and consumables supplies that has actually prevented an expansion of metal supply capacity. The implication is that prices might not adjust as much as expected. Having said that, prices are high in part because of that tightness, so any relief will be bad for prices. But that need not be true for all markets. A number of projects have not proceeded because they were out-bid for plant by bigger projects controlled by bigger companies. The iron ore, bauxite miners have got their ball mills before a small gold miner. So supply has been curtailed in some commodities more than others.
