Yen surging at the possible start of the 2016 debt crash

Charting the USDJPY along with the JPYUSD shows hoe this currency pair fluctuates in multiyear trends around a mean value. The flight to the Yen as a safe haven (Japan is not a debtor nation unlike the USA) proceeded the 2008 crash and started when the US stocks were overvalued and the housing bubble was being recognized. The concern now is for a global debt crash. Negative Interest Rate Policies (NIRPs) and high Debt/GDP ratios are not viable long term.

The recent surge to the Yen with extremely high volumes is quite alarming. On June 9, 2016 I put 12% of my retirement 401k into YCL (long YCL = short USDJPY). I consider this a long term hold.

I have done a lot of research but am new to this. Don't make major plays based solely on my posts as I have no track record of success.
