Interest rate maintenance for the US dollar now clears the way for the yen to strengthen in the inevitable flight to safety. I was a bit conflicted before with the specter of a rate hike which would strengthen the US dollar vs the yen. Now that is confirmed to be a non-factor, we will likely see at least a retrace to the recent low we hit not long ago. Moreover, the SP500 was quite despite the scenario of 0 interest rates and possible QE4 in the future. This could indicate a serious change in market attitude toward this ongoing regime of zero to negative interest rates.
Of course, how equities perform tomorrow will be important to confirm this, but as of now I already have some aggressive positions in the USDJPY and may add more shorts depending on upcoming price action.
