GDP is simply inflation

  If GDP rises, I expect the price of commodities to rise as well. GDP is only a reflection of inflation. The higher the GDP, the higher the inflation. Which is why in 2008, when experiencing the financial collapse, prices actually fell and there was a sudden stroke of deflation. During the IT bubble and realestate bubble, we were all experiencing inflation through high commodity prices, and high housing prices.

  The financial collapse in 2008 was the worse year for commodities.

 

  Gold only grew a meager 5 percent against the usd in 2008. It even depreciated against the Chinese RMB and the Japanese Yen as people fled gold and purchased RMB and Yen instead. 

  I suppose some people who trade commodities trade out of the doom and gloom reports of an impending global collapse. And that is what motivates them to buy hard assets. There is some logic to that being that why hold a national currency if that nation-state may not even exist. Why buy stocks when stock markets will cease to exist. Thus only gold and silver acts as a safe haven. 

  But I do not think that is always a fair assumption to make. If the economy does recover, then you can expect more paper money in people's wallets and in their checking accounts. And if they have more money then that motivates a rush towards spending, whether it is into securities or into commodities. And what really drives the price upwards is the inflation induced by economic growth.
