The Big Picture

Japan is attempting the most consequential economic experiment in a generation — exiting 30 years of deflation — and it just got interrupted by a war. The Bank of Japan has raised rates for the first time since 2007, workers are getting their biggest pay raises since 1991, and yet the whole project has been thrown into limbo by an oil price shock from the Iran conflict that Japan can do almost nothing about.

Think of it like trying to restart a car that hasn't run properly for three decades. You finally got the engine to turn over — and then someone poured sand in the fuel tank.

System view: The BoJ cannot raise rates further (it would deepen the growth slowdown) yet cannot cut them (it would accelerate the yen's decline from an already alarming 157 per dollar). Spending $65B on currency intervention buys time but not a solution [4,5]. Confidence: Medium-high. This assessment would flip if: (a) oil drops below $85 and removes the external pressure, or (b) the yen blows through 165 and forces the BoJ to hike for currency-defense reasons regardless of growth.

If you remember one thing from this report: Japan finally proved it can generate wage growth and escape deflation — the 5.26% spring wage increase settled that question. The new question is whether an oil shock from the Middle East will strangle the recovery before wages can flow through to consumer spending.

What the BoJ Is Doing and Why It Matters

The Bank of Japan has raised its overnight rate from negative territory (-0.1%) to 0.75% over the past two years [9] — modest by global standards, but the most sustained tightening Japan has attempted since 2006. The BoJ has also revealed it thinks the "correct" rate is somewhere between 1.1% and 2.5% [10], telegraphing that more hikes are coming eventually. But "eventually" is doing a lot of work in that sentence.

At its April 28 meeting, the BoJ held rates steady and explicitly blamed the Iran war for the pause [14]. Board members are openly contradicting each other — one calling for faster hikes [11], another questioning whether rate increases even make sense when inflation is being driven by oil imports rather than domestic demand [12]. A former governor publicly stated that raising rates to 1.5% would pose "no problem" [13], which tells you where the internal ceiling sits.

Is the medicine working? Sort of. Short-term borrowing costs have risen (the 3-month interbank rate hit 1.27% [18]), and bond yields have surged to 29-year highs [16]. But the yen keeps weakening anyway because the gap between US rates (3.5-3.75%) and Japanese rates (0.75%) is still enormous — about 2.75 percentage points [7]. As long as that gap exists, investors borrow in yen and invest in dollars, pushing the yen down regardless of what the BoJ does domestically.

The inflation picture is contaminated. Japan's core inflation (stripping out food and energy) sits at 1.61% [24] — still below the 2% target. But headline inflation jumped in April because Japan imports 70% of its oil from the Middle East [31]. The BoJ cannot fix imported energy costs with interest rate policy. It is watching the problem unfold with limited tools.

Most likely path: Hold at 0.75% through summer. If oil retreats below $90 and household spending picks up by July, a hike to 1.0% becomes likely. If the energy shock persists and the yen weakens further, the BoJ faces the paradox of hiking into a slowdown purely to defend the currency — a rare and risky move.

The Economy Under the Hood

The wage breakthrough is real, but it has not reached people's wallets yet. Spring wage negotiations delivered a 5.26% average raise across 1.42 million union workers [26] — the biggest since 1991. Small companies got 5.05% [27], closing the gap with large firms. This definitively answers whether Japan can generate sustained wage growth. It can.

But here is the catch: real wages (what people actually experience after inflation) remain negative [28]. Prices are rising faster than paychecks. The share of household budgets going to food hit a 44-year high [29]. People are cutting spending even as their nominal pay rises [30]. The wage-to-spending-to-services-prices chain — the mechanism that would prove Japan's deflation era is truly over — has not activated.

Industrial production has flatlined. Output growth hit 0.0% year-over-year in February, down from 2.5% in January [35]. Auto production dropped 2.1% in a single month [36]. This is the energy shock hitting manufacturing — Japan's factories run on imported fuel, and that fuel just got 63% more expensive.

The corporate sector looks great on paper. Business confidence surveys (the Tankan) hit multi-decade highs in Q1 [37] — but the survey closed before the Iran war's cost impact materialized. Business sentiment has already "slumped" since then, with bankruptcies expected to rise [38]. The Q2 Tankan (released in July) will tell the real story.

Demographics remain the binding constraint. Japan's working-age population is shrinking by about 200,000 people per year [43]. The child population just hit its 45th consecutive annual record low [44]. Unemployment is 2.8% [40] — not because the economy is booming, but because there simply are not enough workers. This caps long-run growth at roughly 0.5-0.7% regardless of policy.

Assessment: The corporate sector and labor market are telling an optimistic story (record profits, big wage gains, low unemployment). The household sector is telling a pessimistic one (falling real incomes, spending cuts, food budget stress). The next two months of consumer spending data will reveal which story is closer to reality.

What Could Go Wrong (and Right)

Financial markets and the real economy are telling different stories. The Nikkei stock index is up 70% in the past year [64], hitting all-time highs. GDP growth, meanwhile, is running under 1% [7]. This is the widest gap between stock prices and economic output since the late 1980s — and Japan's investors remember how that ended.

The stock rally is partly a mirage: a depreciated yen flatters corporate earnings when translated from foreign currencies, and governance reforms have made Japanese companies more shareholder-friendly. But a 70% equity gain on sub-1% GDP growth is the kind of divergence that resolves suddenly and painfully — usually when the yen reverses. The July 2024 precedent, when a BoJ rate hike triggered a multi-day global sell-off, remains fresh.

Probability bridge: We start with quantitative base rates and adjust. The "clean exit" scenario gets a boost from 15% to 20% because the 5.26% Shunto result resolved the structural prerequisite — Japan proved it can generate wage growth [6]. It gets dragged back by the energy shock disrupting transmission (-3 percentage points). The "wages chase prices" scenario drops from 40% to 30% because real wages are still negative — the spending link is broken [28]. Net adjustments: +5 for clean exit on wages, -10 for spiral on broken spending, flat on yen crisis. Total: 100%.

What bonds look like in this environment: Government bond yields at 2.35% are already at 29-year highs [2]. If the government increases spending (the new PM wants to) while the BoJ reduces its bond buying, supply increases while demand falls — pushing yields higher. For patient holders, these yields represent the first real income from Japanese bonds in a generation. The risk: if fiscal expansion collides with central bank tightening (the "Takaichi vs BoJ" tension), yields could overshoot to 3%+, creating losses for existing holders.

What stocks look like: Japanese equities benefit from the depreciated yen (export earnings translate into more yen) but are vulnerable if the yen suddenly strengthens. A carry trade unwind — where leveraged investors simultaneously exit their yen-funded bets — would crash stocks and strengthen the yen at the same time, as happened briefly in July 2024. The risk: if the BoJ surprises with a rate hike for currency-defense reasons, or if global risk appetite collapses, equities could correct 20%+ [77].

What the yen looks like: At 157 per dollar with $65B of intervention deployed, the currency is being actively defended rather than fundamentally supported [76]. If normalization succeeds, the yen appreciates to 148-152. If the rate gap persists, further weakening toward 160-165 is likely. The risk: intervention fatigue — Japan has the world's second-largest reserves ($1.25 trillion [54]) but cannot spend them indefinitely.

What to watch:

1. June household spending — if it turns positive in real terms, the wage-to-spending link is activating and normalization odds rise substantially
2. Q2 Tankan survey (July 1) — if large manufacturer confidence drops below 10 (from 17), recession risk rises
3. Oil prices — if Brent retreats below $85, the entire external pressure dissipates; above $120, the yen crisis intensifies
4. FX reserves — if they fall below $1.15 trillion, intervention capacity is thinning
5. The yen itself — if it weakens past 165 without a ceasefire in sight, the BoJ may be forced to hike purely for currency defense

The Leading Indicators

Scorecard: Of the 6 key indicators, 3 are flashing warning signals (bonds, yen, credit gap), 1 is stalling (industrial output), and 2 are accelerating in ways that complicate policy (inflation up, oil up). Zero indicators are in crisis territory — yet.

Real-time check: The lagging indicators tell a reassuring story. Credit is still growing at 4.3% per year [86] despite higher yields — businesses are still borrowing. Bank balance sheets are clean (bad loans just 1.2% of total [88]). Unemployment fell to 2.8% [40]. The economy is absorbing the shock without structural damage so far. But the imported inflation channel has confirmed — prices are responding to the oil surge [87]. The June-July data window is decisive: if household spending and business confidence hold, Japan's experiment survives the interruption. If they crack, the most promising economic transformation in a generation stalls out.
