Yen poised for best week in over a year; dollar waits on US jobs data

Traders were left on tenterhooks for any further huge swings in the yen after Tokyo is suspected to have intervened to support its currency this week to the tune of some 9.16 trillion yen ($59.79 billion), as suggested by data from Bank of Japan (BOJ). Japan's latest forays into the currency market came during periods of thin liquidity, with the country out for a holiday on Monday while the second attempt happened late on Wednesday after Wall Street had closed. The yen has strengthened nearly eight yen against the dollar since the start of the week, when it first slid past the key 160 per dollar level which some have said could be the line in the sand for authorities.
