Japanese authorities could hold off on interventions to shore up the yen until Friday's U.S.-holiday thinned market conditions, ING's Chris Turner says in a note. Moreover, the market will have had the chance to react to comments from Federal Reserve Chair Kevin Warsh on Wednesday and the U.S. nonfarm payrolls report on Thursday. There's also a chance Japan holds out until shortly before the next Japanese public holiday on July 20, he says. Nonetheless, interventions can only slow rather than reverse the yen's fall, he says. A reversal would require some "dramatic" Bank of Japan rate hikes and a weaker dollar. The dollar rises 0.2% to 162.30 yen, having reached a 40-year high of 162.41 earlier, LSEG data show.
