'Marc Faber : Cash at 0% doesn’t accumulate wealth either. The moment central banks implement monetary policies where they keep interest rates negative in real terms, in other words interest rates are lower than the rate of cost of living increases, then it is very difficult to value anything. The only thing I can say is, Mr Ben Bernanke, Chairman of the Federal Reserve, and other central banks, they can print an unlimited quantity of money, but you cannot print gold. Gold is limited by its annual supply of around 2,500 tonnes annually. So it is not that gold is going up, it is that the paper value of money, the purchasing power of money is going down vis-à-vis a unit of account, which is gold.'
