USD/JPY Momentum Stalls Near 159.30; Intervention Risk Looms – Friday, 29 May

Where we are: USD/JPY is trading at 159.27, hovering just above the overnight low of 159.20 and below the overnight high of 159.38. The pair remains close to levels that triggered suspected intervention in late April, fueling caution among traders. The current level is marginally higher versus yesterday’s NY close.

What’s driving it: The slow normalisation bias at the Bank of Japan continues to weigh on the Yen. While Ueda has flagged a willingness to hike further if the outlook tracks projections, the market remains unconvinced of aggressive action. The fact that wage data from the spring shunto consolidates the case for one more hike this year has given only a marginal boost. The risk of intervention by the Ministry of Finance and the BoJ looms large, especially with USD/JPY lingering above prior intervention zones; the Finance Minister has already warned about excessive volatility, raising communication risk.

  • The 2Y JGB yield is slightly higher at 1.364%, up 1bp on the day, offering limited support to the Yen.
  • Speculative positioning remains crowded short in JPY, with net non-commercial positions at -93,905 contracts, near the 4th percentile of its 52-week range, raising squeeze risk.
  • The US-JP 10Y yield spread remains wide at +178bp, favouring USD over JPY.

NY session focus: The US data calendar is light today, placing greater emphasis on risk sentiment and USD dynamics. Watch DXY, currently at 99.01, and US 10Y yields, currently at 4.439%, for direction. A break above 159.40 in USD/JPY could trigger further short covering, while a sustained move below 159.00 might signal increased intervention risk. The working trade is still fading Yen strength. The at-risk trade is pressing USD/JPY longs into the weekend given intervention risk. The pain trade is a surprise BoJ announcement or a coordinated G7 intervention.
