Iran rejects U.S. war proposal, says no talks before conditions met
A sharp rise in the price deflator and accelerating wages point to a lasting shift in Japan’s macro backdrop. Here’s why these trends matter for BOJ policy and USD/JPY performance.
- Japan GDP deflator revised up to 3.4%, signalling entrenched inflation
- Nominal wages rose 2.6% in October as unions target 5% hikes next year
- Persistent wage growth suggests structural inflation shift
- BOJ hike odds near 90% for December, reinforcing bullish tone for yen
Summary
Japan’s inflation story is evolving fast. A sharp upward revision in the price deflator and accelerating wage growth point to a structural shift away from decades of disinflation. With unions pushing for sizeable pay hikes and markets pricing a near-certain BOJ hike in December, the yen’s bullish tone looks increasingly supported.
Inflation Signals Strengthen Despite GDP Downgrade
Japan’s economy contracted more sharply than first reported in the September quarter, with GDP falling at an annualised pace of 2.3% compared to the initial 1.8% estimate. The downgrade was driven by weaker capital spending, reversing an earlier estimate of growth, while private consumption saw only a modest lift. Japan’s trade exposure means GDP growth often sees large swings, especially this year with the added layer of rapidly changing U.S. tariff policy. As a result, the latest contraction carries little implication for the BOJ’s near-term policy stance.
Alongside the growth revision, the implicit price deflator—a broad gauge of economy-wide price pressures—was revised sharply higher to 3.4% from 2.8%, continuing the elevated readings seen over the past two years. This suggests inflationary forces are becoming entrenched, reinforcing signs of a structural shift away from the disinflationary backdrop that has dominated since the early 1990s. If sustained, this trend marks a significant change in Japan’s macro environment.

Wage Growth Adds Momentum
Building on the upward revision in the implicit price deflator, wage data released earlier in the session added further evidence of persistent inflationary pressures. Nominal wages rose 2.6% in October, the fastest pace in three months, supported by gains in base pay, overtime, and bonuses. Regular pay increased 2.6%, while overtime climbed 1.5%, pointing to underlying strength in labour demand. With unions pushing for wage hikes of 5% or more in next year’s spring negotiations, similar to the increases secured over the past two years, it would make the case for sustained inflationary pressures as wage-setting dynamics become further entrenched.
Despite the acceleration in nominal pay, real wages fell for a tenth consecutive month, sliding 0.7% from a year earlier as consumer prices continued to outpace earnings growth. While purchasing power remains under strain, the persistence of nominal wage growth alongside elevated inflation signals a structural shift in Japan’s economy where wage trends rather than price shocks may increasingly shape policy and investment decisions.
As discussed earlier, the downward revision to GDP has not altered market expectations for a BOJ rate hike later this month, with pricing continuing to lean heavily toward a move.
BOJ Policy Implications

Market pricing continues to lean heavily toward a rate hike at the BOJ’s December meeting, with overnight index swaps implying a 90% probability of a 25 basis point increase. That confidence has built steadily since Governor Ueda’s hawkish remarks last Monday, marking a clear shift in expectations for near-term policy.

Further out, Japanese five-year OIS now trades at 1.383%, almost double where it began the year. This measure reflects the average level markets expect overnight interest rates to hold over the next five years, making it a useful gauge of medium-term policy expectations. The sharp rise underscores growing conviction that the BOJ will move away from its ultra-loose stance and normalise policy over time. The hawkish repricing has combined with increased JGB issuance to fund the government’s latest stimulus package, pushing yields higher across the curve in recent months.
As outlined in my week-ahead note which also looks at this week’s Fed decision, these dynamics have been a key driver of recent yen strength. Rising domestic yields, coupled with expectations for sustained inflation and wage growth, have narrowed rate differentials with other major economies, reinforcing the bullish tone for the currency.
Impact on Yen and Technical Outlook

As seen on the daily chart above, USD/JPY was rejected at downtrend resistance dating back to the highs set in November earlier, casting doubt on the bullish signal generated last Friday as a sharp reversal from 154.45 helped deliver a hammer candle.
Those two levels remain the ones to watch as we move towards the Federal Reserve’s December rate decision on Wednesday. With RSI (14) pushing lower towards the neutral 50 level, I’m inclined to put more weight on price action to assess setups, especially with MACD also revealing rapidly diminishing upside strength, having already crossed the signal line from above in late November.
Should we see a sustained break of the November downtrend, the highs set last month may act as a magnet for the pair, although pay attention to big figures along the way given USD/JPY did plenty of work either side of 156.00 and 157.00 earlier in the bearish retracement.
Should the price push beneath 154.45 and close there, bears may eye a return to 153.00 with only minor support at 153.68 and the 50DMA located in between.
