USD/JPY outlook: BOJ holds steady as intervention risk builds

• BOJ keeps rates unchanged in July, as expected 
• Single dissent points towards slower policy normalisation
• USD/JPY rebounds extends beyond 160 following rate decision
• Near-term intervention threat clouds bullish USD/JPY outlook

Intervention first, tightening later?

The Bank of Japan left interest rates unchanged at 1% in July, as widely expected by markets. There had been some speculation the BOJ may deliver a surprise rate increase following likely coordinated intervention between Japan's Ministry of Finance, the US Treasury and South Korean officials on Thursday, but that failed to materialise.

Notably, there was only one dissenter, Takata, who voted in favour of a 25 basis point increase, arguing upside risks to prices had increased sufficiently to warrant a more pre-emptive policy response.

That's important because previous BOJ tightening episodes have generally been preceded by meetings where multiple dissenters emerged. The fact there was only one on this occasion suggests, at face value, that September may be off the table for a hike, with October or December looking more likely for the next move, broadly in line with current market pricing.

Growth optimism offsets softer inflation

Beyond the policy decision, the updated Outlook Report continued to point towards further policy normalisation, even if the timing of the next move remains opaque.

While the Bank lowered its near-term inflation forecasts, it remained optimistic on the outlook for economic activity, expanding its commentary on AI, semiconductor-related investment and business spending as important drivers of growth.

On inflation, the BOJ said wage and price-setting behaviour among firms is continuing to shift, helping underpin its expectation that underlying CPI inflation will gradually move towards its 2% target over time. However, it acknowledged uncertainty remains elevated, particularly around global trade policy, overseas economic activity and developments in financial markets.

Overall, there was little in the forecasts to suggest the direction of travel for policy has changed. While the timing of the next rate increase remains data dependent, the BOJ still appears biased towards further gradual tightening.

Yen weakness quickly returns

The initial market reaction suggests traders have interpreted the outcome as dovish, with the yen resuming its slide after Thursday's spectacular rally. With USD/JPY already back above 160, it raises fresh questions about exactly what Japanese authorities were trying to achieve through what appeared to be coordinated intervention.

At face value, it may have been conducted to provide room for the BOJ to deliver a more dovish outcome without immediately inviting another wave of yen selling. Had intervention not taken place, leaving policy unchanged may have risked a far stronger market reaction and another push towards fresh multi-decade highs in USD/JPY.

While you wouldn’t know from the market reaction, the risk of further intervention remains elevated. If Japanese authorities revert to the playbook seen earlier this year, intervention may come in waves over several days rather than as a single event. That's an acute risk for anyone chasing USD/JPY higher.

Attention now shifts to Governor Ueda's press conference at 3:30pm Tokyo time. If history is any guide, he has a habit of sounding more dovish than the policy statement, keeping the risk of renewed USD/JPY upside firmly in play.

160.73 becomes the focal point

The first thing that stands out on the daily chart is just how respectful USD/JPY remains to known technical levels, despite what appears to have been intervention from Japanese authorities. The violent unwind stalled almost perfectly at the confluence of the 200-day simple moving average and 157.92, a former breakout level from earlier this year, before buyers stepped back in.

That rebound has since taken USD/JPY back to 160.73, the former record high set earlier this year. While the pair briefly traded above that level, it has so far struggled to establish a foothold, leaving it as an obvious pivot for traders.

For those anticipating further bouts of likely intervention, 160.73 looms as a level to build setups around, allowing traders to consider initiating shorts beneath the level with a stop above, targeting a move back towards where the bearish unwind on Thursday stalled just beneath 158. However, just because earlier intervention episodes came in waves doesn't mean that pattern will necessarily be repeated this time.

Conversely, if USD/JPY can reclaim 160.73 and hold above it, it would suggest intervention-related selling may have run its course for now, allowing traders to consider initiating long positions above the level with a stop beneath, targeting a move towards the former uptrend from early May, found today just beneath 162. Above that, 162.84 and then 164 become the next upside levels to watch.

Even though the longer-term trend remains undeniably bullish, favouring buying dips, the ongoing threat of further intervention means chasing USD/JPY higher near term looks unappealing.
