Inflation Shocks
Who Can Hold Rates Steady?

The Hormuz closure is not just an oil event — it is a central bank stress test.
Every economy now faces a forced choice: defend its currency or protect its growth.
The answer depends on one variable: how many days of oil can you buy yourself before the pain arrives.
Japan buys 254 days. India buys 45. That gap is the investment thesis.

| Economy | SPR (Days) | Hormuz Dependency | CB Constraint |
|---|---|---|---|
| Japan | 254 | >90% | Least constrained — 8+ months of buffer |
| USA | 146 | Low | Moderate — domestic pump = political risk |
| China | ~108 | 84% | Moderate — state caps absorb shock initially |
| Europe | ~90 | High (LNG) | High — stagflation squeeze; ECB cornered |
| India | ~45 | Very high | Extreme — INR at risk; RBI defence costly |
| SE Asia | 20–60 | Very high | Extreme — subsidy budgets near exhaustion |
C Koh’s framework: rates drive asset performance. Who is forced to hike? Who can sit still? That answers the portfolio question.
| Economy | Shock Severity | CB Dilemma | Rate Path | Currency Outlook |
|---|---|---|---|---|
| Japan | Moderate | Hold rates to support growth; 8-month buffer = flexibility | Gradual — BoJ not forced | JPY: steady to firm |
| USA | Low | Inflation creep vs. growth; domestic pump politics | On hold — Fed in wait-and-see mode | USD: firm (petro-hedge) |
| China | High | Deflation meets import inflation; state caps suppress CPI | Hold — PBOC absorbs via refiners | RMB: mildly pressured |
| Europe | High | Stagflation — ECB can’t cut; diesel >€2/L already | Higher for longer — ECB cornered | EUR: weakens vs USD |
| India | Extreme | Defend INR or protect growth — cannot do both | Defensive hike — RBI forced to act | INR → 100/USD risk |
| SE Asia | Extreme | Subsidy exhaustion → shock hike when budgets snap | Forced hike — fiscal wall approaching | SGD/THB/IDR: pressured |
Japan’s 254-day buffer is not an accident. Decades of deliberate stockpiling — driven by the memory of the 1973 oil shock — mean that the Bank of Japan faces less inflation pressure than any other major central bank. While the ECB is cornered and the RBI is forced to choose between its currency and its growth, the BoJ can move gradually. That policy flexibility is the investment edge.
Sogo Sosha — Buffett’s genius confirmed. Japan’s great trading houses (Sogo Sosha) — Mitsubishi, Mitsui, Sumitomo, Marubeni, Itochu — secured long-dated energy futures years ago. When the Hormuz logistics bottleneck bites, these firms can buy crude on the forward curve and take delivery six months later, bypassing the spot market chaos entirely. The thesis Buffett backed in 2020 is now paying off in ways even he may not have anticipated.
EUR should appreciate against JPY. The rate divergence is the mechanism: the ECB is forced higher for longer (stagflation), while the BoJ stays gradual. Rate differentials historically drive FX. The irony is that Japan’s energy resilience — its greatest economic strength in this crisis — becomes a relative currency headwind as BoJ hikes lag ECB hikes.
On this score, Japan is a super overweight. The combination of the largest SPR buffer, the most policy-flexible central bank, and structurally energy-hedged corporates makes Japan the standout conviction position in a Hormuz-disrupted world.
Not investment advice. For discussion purposes only. Positioning reflects the SPR buffer and rate path framework above.
| Stance | Region / Asset | Rationale |
|---|---|---|
| Overweight | USA, Japan, Brazil | Energy sovereign / largest buffers; BoJ/Fed least forced to hike |
| Neutral | China | Massive stockpile but 84% maritime exposed; state caps absorb short-term |
| Underweight | Europe, India, SE Asia | Import drain + currency pressure + CB forced to hike into slowing growth |
| Avoid | Leveraged assets (REITs, geared tech) | Rate + margin double squeeze; refinancing cost rises hit hardest |
| Favour | Healthcare, Consumer Staples, Copper | Inelastic demand (healthcare/staples); copper = energy-transition inflation play |
| Copper > Gold | Industrial metals vs. gold | Gold is now rate-correlated; copper is the structural inflation hedge for the energy transition |
“Even for a staple like sushi, rising oil permeates everything. Fishing boats need fuel. Logistics costs are fuel. Rental in prime locations rises with capex costs. The multiplier runs up the entire food chain.”
— C Koh, March 2026
This is the PPI-to-CPI transmission mechanism in microcosm. Energy costs are not confined to petrol stations. They embed in every layer of the supply chain: production, cold storage, last-mile delivery, commercial rents. The economies with the longest buffers buy the most time before these multiplier effects compound into headline inflation numbers the central bank must respond to.
The framework is simple. Find the economy that can raise rates slowest. That economy’s assets will outperform because its central bank is not being forced to trade growth for stability.
Japan and the United States are the most buffered. The BoJ can stay gradual. The Fed can stay on hold. Their equity markets and currencies face less rate-driven headwind than the rest of the world.
Europe and South-East Asia are the most constrained. The ECB faces a stagflation trap — it cannot cut without losing credibility, and it cannot ignore growth. ASEAN governments face a fiscal cliff as subsidy budgets exhaust. When the subsidy wall breaks, inflation arrives suddenly.
India is the outlier to watch. The INR approaching 100/USD is not just a currency story — it is a confidence event. If the RBI is forced to raise rates into a slowing economy to defend the currency, Indian equities face a double squeeze from rising discount rates and falling corporate margins.
Stagflation risk is the portfolio killer, not the oil price itself. A high Brent price is manageable if your central bank can hold steady. The real danger is the economy where the central bank is forced to hike into slowing growth — and that list is longer than the market currently prices. Banks dare not write this. The market has not fully priced the divergence.
Key Takeaways
- The SPR buffer determines CB flexibility. Japan (254 days) and the US (146 days) have the most room. India (∼45 days) and SE Asia (20–60 days) have almost none.
- The ECB is the most constrained major central bank. Stagflation — high import inflation + slowing growth — removes optionality. Higher for longer is the only credible path.
- BoJ is the most policy-flexible central bank. Gradual normalisation, not forced hikes. Japan equity and JGB markets absorb less rate-driven turbulence than Europe or EM.
- Sogo Sosha forward-curve energy hedges are now paying off. Long-dated futures booked years ago bypass spot chaos. Buffett’s 2020 thesis validated under conditions he likely did not model explicitly.
- Copper over gold in this regime. Gold trades increasingly as a rate instrument. Copper is the physical inflation hedge tied to the energy-transition industrial cycle.
- The food chain effect compounds with a lag. PPI-to-CPI transmission is not instant. Economies with thin buffers will see second-round inflation effects arrive 3–6 months after the supply shock, just as their CBs are most constrained.
