Japanese yen weekly outlook: BOJ intervention threat leaves USD/JPY on edge

 

• BOJ intervention threat resurfaces
• Stretched yen positioning raises squeeze risk
• Fed speakers and FOMC minutes take centre stage
• Bearish technical signals challenge buy-the-dip mentality

Intervention or short squeeze?

Thursday's abrupt decline in USD/JPY reignited speculation that the Bank of Japan may have stepped into the market on behalf of Japan's Ministry of Finance. Whether that was the case remains unclear, but it's plausible the move reflected a combination of other factors, including a well-timed Reuters report suggesting Japanese authorities may be looking to catch speculators off guard, heavily stretched short yen positioning, thinning liquidity ahead of the US payrolls report and Independence Day holiday, and Federal Reserve Chair Kevin Warsh striking a slightly less hawkish tone only hours earlier.

Whatever the catalyst, the combination of stretched speculative positioning, bearish technical signals and lingering intervention risk has markets on edge heading into the week ahead.

Market positioning helps explain why. While futures positioning captures only a small part of the broader FX market, it provides a useful proxy for speculative sentiment. Right now, it points to short yen positioning bordering on extremes, reinforcing the risk that any catalyst capable of triggering a squeeze could generate an outsized market reaction.

While the risk of further intervention shouldn't be dismissed, the experience earlier this year suggests it may do little more than slow USD/JPY's advance. For any move lower to be sustained, it would still need to be accompanied by a meaningful shift in the underlying fundamentals encouraging investors to sell the yen.

Fed communication in focus

With intervention risk elevated, the focus this week shifts back to whether incoming data and central bank communication do anything to alter the underlying macro backdrop.

The US economic calendar is light. Monday's ISM services PMI will attract attention, particularly the prices paid component following the sharp slowdown seen in the equivalent manufacturing measure released last week. But as a sentiment survey, it may struggle to materially alter the broader outlook on its own.

Instead, the focus is likely to fall on remarks from Federal Reserve Governor Christopher Waller and New York Fed President John Williams. Both are widely viewed as influential voices within the FOMC, making any insights into how the Committee is thinking following the June employment report, recent declines in energy prices and Kevin Warsh's comments at Sintra worth watching closely.

While they're unlikely to provide definitive guidance, any clues on how the perceived centre of the Committee is assessing the evolving macro backdrop could carry far greater significance for USD/JPY than the second-tier data scheduled this week.

The June FOMC minutes also loom as a potential volatility event. Historically, the minutes have rarely generated a sustained market reaction, but this release may prove different given it relates to Kevin Warsh's first meeting as Fed Chair. Any clues on how policymakers are weighing inflation risks relative to labour market developments, and what they need to see before either tightening policy again or remaining on hold, will be eyed closely.

Testing the virtuous cycle

The Japanese calendar also carries event risk with Tuesday's wage and household spending reports providing another test of hawkish BOJ pricing. Real wage growth has finally turned positive in recent months and, to keep another rate hike in play later this year, you'd imagine that trend needs to continue. Household spending will be just as important given it accounts for more than half of Japan's economy and stronger consumption remains central to the BOJ's long-held goal of creating a self-sustaining cycle of stronger demand, faster wage growth and higher inflation.

Tuesday also brings a 30-year JGB auction worth watching after renewed selling pressure emerged at the ultra-long end of the curve last week. The bond market still appears to be signalling policy settings remain too loose. Unless the BOJ moves real policy rates towards positive territory, pressure is likely to remain on both the yen and the back end of the JGB curve.

Friday's producer price inflation report rounds out the week. Factory gate prices are still rising at an annual pace above 6%, reflecting the earlier jump in energy prices along with the pass-through from yen weakness. To keep another BOJ rate hike on the table this year, pipeline inflation pressures will likely need to remain firm. A sharp slowdown would naturally raise questions over whether the same lies ahead for consumer prices.

Technical picture begins to shift

For the first time in months, the technical picture for USD/JPY is no longer overwhelmingly stacked in favour of the bulls. Thursday's completion of an evening star reversal pattern from the multi-decade high at 162.84 warns downside risks may be beginning to build. That view is reinforced by the momentum indicators. RSI (14) has broken the uptrend that's been in place since the latter part of April, although it remains above the neutral 50 level. MACD has also crossed beneath its signal line, but remains in positive territory. At the very least, both are warning that the strong upside momentum which had been in place for months has weakened sharply.

Despite those signals, the price continued to respect important technical levels late last week. The pair found support almost to the tick at 160.73, the former 2026 high set in late April, before rebounding on Thursday. Buyers stepped back in from the same area on Friday, with 160.73 also coinciding with the uptrend that's been in place since the middle of May. That leaves the area as the key downside level to watch this week. A break would shift the focus to the 50 and 100-day moving averages before exposing 157.92, the breakout level established in May following the previous intervention episode.

Should Friday's rebound extend, the 2024 high at 161.95 becomes the first topside level to watch before attention turns back to the multi-decade high at 162.84. The broader uptrend remains intact, but for the first time in months the technical picture is no longer screaming "buy the dip".
