The yen’s slump past the symbolic mark of 150 per dollar is keeping traders guessing when Japanese authorities will intervene to halt a further decline.
The Japanese currency has weakened by more than 5 yen per dollar since Japan stepped into the market in September, despite a barrage of warnings to dissuade traders from testing its resolve and speculation authorities were quietly intervening on a small scale. The yen slipped another 0.8% on Friday to 151.38, a 32-year low.
