As we all know, almost every central bank in the world is printing money to boost exports and support asset prices in the stock market. To their credit, the money printing idea has worked as markets around the world have been rallying. Japan is now the most aggressive money printing country. The Bank of Japan (BOJ) said that they would put $1.4 trillion into the economy over the next two years. The Nikkei 225 Index (Japanese stock market) has gained nearly 7,000 points or 80.0 percent since October 2012. This rally in the USD/JPY, and the Nikkei 225 Index has been parabolic and shows the power of money printing or the devaluing of the currency.
At this time, the major stock indexes around the world seem to be trading higher when the Japanese Yen declines against the U.S. Dollar. Traders can simply look at the chart below and see how the S&P SPDR 500 Trust (black line) and the USD/JPY (green line) trade higher together. The red line is the SPDR Gold Shares which is trading inverse to the USD/JPY. The bottom line, if the Japanese Yen starts to strengthen against the U.S. Dollar the current rally in stocks could come to an abrupt end.
