The Nikkei newspaper reported that the Bank of Japan (BOJ) conducted rate checks with banks on the euro against the yen on Friday, and traders were still reeling from the aftermath of Thursday’s suspected yen-buying intervention.
Authorities were cagey about it as usual, but if anything, Tokyo has clearly shown the market that it knows when to best time an intervention.
Thursday’s spike in the yen came straight after data showed U.S. consumer inflation cooled more than expected in June, which initially led currency analysts and traders to think that the surge was probably triggered by options-related activity.
Yet, the scale and speed of the move eventually put markets on alert to the possibility of a Japanese intervention and local media similarly attributed it as such.
Given that effects of any intervention have proven short-lived in recent history, Thursday’s move probably provided the best bang for Tokyo’s buck.
Authorities’ absence from the currency market after the April-May intervention bout had at some point raised questions about their restraint as the yen continued to plumb fresh 38-year lows.
But after Thursday’s developments, traders are once again on the edge of their seats.
