In recent weeks the dollar has been steadily weakening, but since Tuesday that decline has intensified. Today the dollar hit all-time record lows against the euro.
Note that in the past year or so, the Japanese CB has started intervening in the currency markets whenever the Yen has fallen below about 108, and they’ve intervened heavily whenever the Yen has fallen near or below 106. In fact, they seem to have drawn a line in the sand at about 105 ¥/$, below which they absolutely refuse to let the exchange rate go. It will be interesting to see if they are still just as committed to that minimum exchange rate this time around.
