The question should be, "Which central bank is the most insane?" Because you understand, the central banks have been manipulating just about everything. They manipulate the currencies, they manipulate interest rates, they manipulate stocks. It's interesting sometimes if you observe in the U.S., when the market is very weak overnight, in other words the S&P futures go down 20, 30 points, suddenly, a buyer emerges and pushes up the market. I believe that the Fed has not just intervened in bonds through Operation Twist, in interest rates through QE programs but occasionally they step into the stock market to stabilize the market and try to push it up. I think other central banks around the world; in Japan, they announce it, the central bank, the Bank of Japan, is buying shares through ETFs.
So there's a gigantic manipulation and you and I, as an investor, we just don't know how far these insane people will go with the manipulation of markets. Now, already 7 trillion dollars' worth of pounds are trading at less than 0 interest.
The talk is that, even in the U.S., they might introduce negative interest rates. Negative interest rates will not help the world, I guarantee you that.
