USD/JPY Nears Intervention Zone as BOJ-Fed Policy Gap Widens

The dollar climbed toward a multi-month high against the yen this week, pushing the pair close to levels that prompted verbal warnings from Japanese officials during previous bouts of currency weakness.

USD/JPY traded near 161.80 in Asian hours, extending a slide in the yen that has been driven largely by a widening gap between US and Japanese short-term interest rates, which remain among the largest in the developed world.

Traders watch for signs of official action

Desk strategists said the pair's approach toward the psychologically significant 162 level has raised the probability of renewed intervention from Japanese authorities, who have stepped into the market on several occasions over the past two years when the currency weakened sharply.

Implied volatility on short-dated yen options ticked higher over the week, reflecting growing trader caution about the risk of a sudden, sharp reversal should officials intervene directly in the spot market.

Some analysts noted that verbal warnings alone have had a limited and short-lived effect in recent cycles, meaning the market may need to see actual intervention before any sustained repricing of the currency occurs.
