Energy Shock Shakes 'Look Through' Doctrine as Multiple Central Banks Pivot to Synchronized Rate Hikes
nashnova research
Six months into the Iran war, the world's major central banks are collectively abandoning the decades-old 'look-through' doctrine — because energy prices have stayed elevated long enough to unanchor inflation expectations, making inaction riskier than tightening.
What is the 'look-through' doctrine — and why has it broken down?
"Look-through" is the central-banking convention of not raising rates when inflation is driven by a supply shock like an oil spike. The bet: the shock is temporary, so ride it out.
That bet works only when inflation expectations stay firmly anchored — consumers and businesses trust the spike will pass. But a cascade of shocks has eroded that trust: pandemic supply-chain chaos, the Russia-Ukraine war, AI-driven computer-price inflation, 18 months of US tariff whiplash, and two rounds of Iran military conflict.
This means → the public's faith in "inflation under control" has been worn down shock after shock. If central banks keep looking through, they are gambling their credibility — and losing that gamble means high inflation becomes chronic.
Who is hiking — and on what timeline?
The ECB completed its hike last week. Swap and futures markets now imply: the Fed hikes this Wednesday, the Bank of Japan hikes this Friday.
The Reserve Bank of Australia, Bank of Canada, and Bank of England are expected to follow within roughly eight weeks.
This reflects a rare episode of globally synchronised tightening — not one central bank's solo call, but a shared energy-inflation pressure that has forced a collective "move now" decision.
How high have energy prices actually gone?
WTI crude futures are back near $100 a barrel. US gasoline prices have hit their highest since May. Diesel has broken $6 a gallon for the first time.
Diesel is called the economy's "workhorse" — it powers electricity generation, home heating, and freight. In plain terms = when diesel rises, the cost of moving and making almost everything rises with it. Its inflation pass-through is wider than crude oil's.
This means → energy prices are no longer confined to the pump. They are seeping through the entire cost chain — and that is the tipping point that made central banks decide they could no longer wait.
How does each economy's position differ?
The eurozone and the UK are most exposed: both rely heavily on imported fuel, including natural gas for homes and industry. Energy price rises hit household bills directly.
Japan is also a major energy importer, but its hike is framed more as a normalisation from ultra-low rates — the energy shock provided a window, not the sole reason.
The US is itself a large energy producer with the strongest economic fundamentals, so the trade-off cost of hiking is relatively lightest. This reflects how the same energy shock inflicts very different levels of pain on different economies.
'Look-through' worked before — why not this time?
Greenspan cut rates during the 1990-91 Gulf War oil spike and was proved right. Bernanke held steady during the 2011 Arab Spring oil surge and was likewise vindicated.
The fundamental difference now: the shocks are no longer isolated — they have stacked one on top of another. In plain terms = before, it was one storm you could wait out; now it is storm after storm, and the roof has started to leak.
The risk of policy inaction now exceeds the economic cost of tightening — whether that judgment holds up will depend on whether energy prices can retreat before winter.
