The paranoia is unbelievable here. The economy is not heading for a depression, maybe a prolonged recession that will last a year or so. The number one factor in kick starting the economy is the housing market and getting credit flowing again, and the signs are starting to point to everything getting back on its feet. The California housing market has leveled off and is starting to pick up again. The Western states of Oregon, Nevada, Arizona, Utah and Idaho are all very close to leveled off or have. The middle of the country will follow. Housing may drop for another 6-12 months in parts of the country, but a drop after that is very unlikely. 2009 will shape up to be a very strong year in the housing market and 2008 won't be as bad as it is like to be thought. In fact, while 2007 was bad, house sales were still pretty high. It just looks bad compared to 2006 which may have been the biggest year ever.
If the economy does go into a depression demand for all commodities will drop causing gold, silver, oil, etc prices to drop and they might drop more than stocks. If the US goes into a depression, the world will follow. The impact that the US has over the worlds markets, is actually quite amazing. Even right now, Europe, Australia and New Zealand are feeling the pinch in our credit markets. The EU may have to lower their interest rates, and New Zealand is saying that economic growth will slow to 3% this year and in just over a year to 2%.
Also, remember that silver is mainly an industrial metal, and if we go into a sever recession the demand will fall for silver. The price will then drop. Commodity-based investing only will lead to failure, stay diversified as much as possible.
