What makes you think 2009 is going to be significant?
Here's the glass-is-half-empty point of view:
By 2009, the Olympics will be over and the Chinese won't be playing nice anymore.
Silver stockpiles will be getting quite low. Demand is unsustainable with current above-ground quantities. Silver has the highest conductivity level of all metals, but it doesn't spark, which makes it great for industrial purposes---everything from bombs to flat screen TVs. But once it's used industrially, it's nearly impossible to recover. Once it's gone, it's gone.
It's no stretch of the imagination to foresee the dollar having eroded quite a bit by then. It's already on its way. I'm guessing that the dollar index will be permanently under 80 by then, which will cause even more central banks diversify out of the dollar even more than they're doing now. The "basket of currencies" approach.
Emerging middle classes is India, China, and Indochina will want something in which to invest that holds its value better than paper or digits on a computer screen.
Remember, for the first time since the great depression, Americans have a negative savings rate. Basically, we're spending money we don't have on things we don't need. This can't last forever. And since a proportionately larger segment of our economy is based on the sevice sector, rather than manual labor and manufacturing, bouncing back from a recession will be more difficult.
A few years ago, the Fed stopped publishing how many dollars it prints every year. Now why would that be? Has anyone bought milk lately? There's your answer.
All of these factors which are just on the horizon, just emerging, will come into play more seriously next year and thereafter. But to be honest, it's a tough game predicting the future. People have better luck reading the tea leaves or gazing into a crystal ball. Remember, I'm guessing here---just a shot in the dark.
I'm a BIS (Bank for International Settlements) junkie, and follow them obsessively. Here's a link that goes into more detail:
