The guessing game continued as Japan entered a long holiday weekend, with multiple news outlets reporting that the government aggressively sold dollars and bought yen and the government itself refusing to say whether it sought to prop up the currency. 
Following decisive jawboning on Thursday, and with reports of intervention overnight, the yen moved rapidly from above ¥160 to the dollar into the ¥155-to-the-dollar range. 
It then settled back above ¥157 to the dollar on Friday as the market sought clarity on what's actually happening. 
The government continued to make bold statements without confirming anything solid about what, if anything, it had done in the markets or what might follow.
