The yenâs surge to its highest level of the year against the dollar has put investors on alert for possible currency intervention by the Japanese authorities this week.
If Japan acts to shield its stock markets and exporters from the rising yen, it will be the first time Tokyo has intervened in the foreign exchange markets since April 2004.
Last week, the yen rose 2.5 per cent to a high of Y86.36 against the dollar, its strongest level since December.
The dollar dropped as fears over the pace of the US economic recovery sent US Treasury yields to record lows and prompted speculation that the Federal Reserve would be forced into another round of âquantitative easingâ.
Concerns over the US economy also propelled the euro up through $1.30 against the dollar for the first time in two months.
Traders said the yenâs break upwards through its December high could open the way for the currency to test the 14-year peak of Y84.80 it hit against the dollar last November.
Once the yen had scaled that peak, they said, the way was open for the currency to test the record high of Y79.70 it hit against the dollar in 1995.
Simon Derrick, head of currency strategy at BNY Mellon, said it was unlikely that the Japanese authorities would allow the situation to go that far, however.
âI think if the dollar goes below Y85 against the yen, Japan will intervene,â he said.
Mr Derrick noted that verbal intervention from officials had done little to stem the rise.
Last week, Masaaki Shirakawa, governor of the Bank of Japan, said the appreciation of the yen hurt exports, while the associated stock price falls had a negative impact on capital expenditure and consumer spending.
Mr Shirakawa said he was continuing to watch currency and stock price movements âcarefullyâ.
in spite of those warnings, the Nikkei 225 average of leading Japanese stocks dropped 2.9 per cent as the yen surged last Friday.
âWhile I am sure the Japanese authorities understand that the yenâs strength is mostly related to dollar weakness, if they see the Nikkei down another 3 per cent, they will have to act,â said Mr Derrick.
âThe danger is that if the Y85 level breaks in dollar/yen, then speculators will quickly target record levels around Y80.â
