The outlook for inflation, growth, unemployment and interest rates
Japan has not escaped its debt problem; it has changed the currency in which that problem is paid. The adjustment is running through the exchange rate and the price level, not through the bond market. That is a slower crisis, and a more insidious one.

The call
Japan is roughly eighteen months into the most consequential regime change of any developed economy since the financial crisis. The Bank of Japan abandoned yield curve control in March 2024, raised the policy rate to 1.00% on 16 June 2026 — the highest since September 1995 — and is running a balance sheet reduction that cuts JGB holdings by roughly a third by 2030. Simultaneously the Takaichi government’s Basic Policy of 21 July removed “fiscal consolidation” from official policy and replaced the primary balance target with a multi-year debt-to-GDP objective. Monetary policy is tightening into a fiscal expansion, and the yen is the release valve.
Our central case is not a crisis. It is something more awkward for portfolio construction: a persistent, grinding repricing of Japanese duration and the yen, punctuated by episodes of disorder around fiscal events.
House view in brief
- Inflation. Measured core CPI is being held some 50–70bp below its underlying rate by energy subsidies and the retail gasoline cap. Core-core ran 1.9% in Tokyo in June against core at 1.6%; the gap is the subsidy. Corporate expectations have anchored above target (June Tankan 2.7% at one year, 2.6% at three and five). Underlying inflation is at, not below, target. We look for core CPI at 2.2–2.5% by Q4 2026.
- Wages. Shunto 2026 settled at 5.01% across 5,368 unions — a third consecutive year above 5% — with SMEs at 4.69% and base pay near 3.85%. Nominal cash earnings +3.2% y/y, real wages +1.4%. The deflationary wage-setting norm has broken.
- The stale FX assumption. Firms are planning FY2026/27 on USD/JPY 152.57 against spot near 162. A six per cent gap between the planning rate and the traded rate is not a forecasting error — it is a pipeline of cost pass-through that has not yet reached the shelf.
- Growth. Q1 was strong on the headline (+0.5% q/q) but poor in composition: net exports and consumption carried it while business investment was revised to −0.7%. Large-firm capex plans at +11.5% against recurring profits −6.7% — investment through margin compression. Roughly 0.7% for calendar 2026.
- Unemployment. At 2.5% the jobless rate is close to uninformative; Japan clears through hours, participation and wages. Watch the vacancy ratio (1.17, falling), new openings (−8.9% y/y) and the Tankan employment DI (−37). 2.5–2.7% through 2027, with no macro significance.
- Rates. Hold on 31 July, hike to 1.25% in October, 1.50% by mid-2027, terminal 1.75–2.00%. The more important call is the curve: continued bear steepening driven by term premium and supply, not policy expectations. The two-year at 1.44% already prices close to terminal; the long end has a great deal of work left.
- The yen. Intervention controls the pace of depreciation, not the level. The MoF spent a record ¥11.73trn across April–May and USD/JPY was back through the intervention level inside six weeks, printing 163.19 on 22 July — a forty-year low, made without a US catalyst and immediately ahead of two central bank meetings. That is not a market trading the rate differential; it is one trading the credibility of the policy mix.
Where we differ: the shadow-yield question
A strand of commentary argues that unsupported Japanese long-end yields would be in double digits. We think that is directionally right about the yen and substantially wrong about the bond. The premise has been overtaken by events: yield curve control ended in March 2024, the Bank is in QT, and the 30-year has already repriced from under 1% in 2021 to 4.00%. The cross-sectional “300bp too low” argument, applied to a current starting point, has largely been closed by the market rather than suppressed. The stock effect is real; the flow effect is not the mechanism — the Bank still holds ¥550–580trn, roughly half the market and concentrated long, which we put at 100–200bp on the 30-year. That is not a cap, and its unwinding is scheduled, publicised and gradual, which is precisely the condition under which markets do not gap. The ECB analogy does not transfer: Italy and Spain issue in a currency they cannot create, so default probability gaps; Japan cannot be forced into nominal default.
In a foreign-currency-equivalent regime, the bond breaks. In a local-currency regime with a printing press, the currency breaks. Japan is the second case.
Our estimate of fair value for an unsupported 30-year JGB is 4.75–5.75%, offered for adjudication rather than as a settled house number. That is a serious number. It is not ten per cent.
Scenarios to end-2027
| Scenario | Prob. | Description | Market expression |
| Base — grinding normalisation | 55% | BoJ 1.25% Oct, 1.50% by mid-2027. Core CPI 2.0–2.5%, growth 0.7–1.0%. Fiscal delivery lags announcement. | 10y 3.10–3.30%, 30y 4.25–4.50%, USD/JPY 158–168. Continued bear steepening. |
| Honebuto-shokku | 20% | Food tax cut plus an uncapped FY2027 request round. Fiscal risk premium repricing, no growth offset. | 30y through 4.75%, 2s30s beyond 350bp, USD/JPY through 170. Unscheduled BoJ operations. |
| Hawkish reaction-function reset | 15% | BoJ accelerates to consecutive moves, explicitly citing the currency. Terminal repriced to 2.25%+. | Front end sells off, curve bull flattens from the long end, USD/JPY 145–150. Global carry unwind. |
| Stagflationary energy shock | 10% | Hormuz re-closure or Gulf escalation. Headline above 3%, BoJ caught between mandate and growth. | Curve twists, yen weakens on terms of trade, equity de-rating. Worst outcome for Japanese assets. |

Implications for Australian fixed income portfolios
- AUD/JPY into the ACGB long end. Our standing house view is that Australian long-end steepening is driven by the unwind of the yen carry trade through AUD/JPY, not by domestic inflation expectations. Nothing here challenges that: a domestic 30-year at 4.00%, heading to 4.25–4.50%, competes directly for the balance sheets of Japanese lifers and trust banks that have been price-insensitive buyers of hedged ultra-long paper. The trigger to monitor is AUD/JPY, not Australian breakevens.
- Carry unwind risk. The hawkish-reset scenario transmits most violently. AUD is a primary carry destination and would bear a disproportionate share of an August-2024-style adjustment; books carrying credit beta and duration together should be sized with that correlation in mind.
- Positioning. Underweight ultra-long duration in both markets; prefer the front end and belly; hold curve steepeners as the cleanest structural expression; treat a sharp yen appreciation as a de-risking signal for credit, not a benign one; floating rate exposure remains the defensive allocation in a term-premium-driven selloff.
