106.84 is a key level in USD/JPY
The 106.84 was touched in the hours before the Brexit vote as the market was increasingly convinced a 'remain' vote was coming.
The 106.84 level is also close to the 61.8% retracement of the decline since the end of May.
The way that Treasury yields and stocks are rising, the uptrend in this pair is a tough one to stop.
