ECB chief warns: High oil prices could force new rate hikes

The warning from Vienna

Martin Kocher, head of Austria's central bank and a member of the European Central Bank's (ECB) Governing Council, has issued a clear warning: persistently high oil prices could force the ECB to tighten monetary policy further, according to the Financial Times (ft.com).

Kocher says the risk that inflation will remain elevated over time has increased noticeably in recent months compared with earlier forecasts. The statement comes at a time when energy prices have once again become a source of uncertainty for monetary policy in the eurozone, following a period in which the ECB has signaled that the peak in interest rates may have been reached.

The risk of elevated inflation is higher now than it was a few months ago

It is worth noting that the statement comes from a single central bank official, not from the ECB's official monetary policy committee. Such individual statements from Governing Council members are often interpreted as attempts to influence market expectations ahead of formal rate meetings, and should be read with that caveat in mind.

Why oil prices carry significant weight

Historically, oil prices have been one of the most direct channels through which inflation spreads into the real economy — via fuel prices, transport costs, and production costs for goods. When energy prices rise, pressure increases simultaneously on both the consumer price index and companies' cost base, making it harder for central banks to distinguish between temporary and lasting inflationary impulses.

For the ECB, which has already spent several years bringing inflation down toward its 2 percent target, a new oil-driven price surge represents a risk that the work will have to be redone — with the interest rate consequences that entails for mortgages, corporate loans, and government bond yields across the eurozone.

The Norwegian angle

For Norway, the picture is more complex than for most other European countries. As a net oil exporter, the Norwegian economy and state revenues benefit from higher oil prices, while households and businesses may simultaneously experience increased costs through imported inflation and stronger currency or interest rate developments.

Norges Bank closely monitors what the ECB does, since interest rate decisions in the eurozone affect the interest rate differential against the Norwegian krone and thus the krone exchange rate. If the ECB is forced to raise rates further due to oil prices, this could also pressure Norges Bank to hold back on its own rate cuts in order to avoid further weakening of the krone.

Lessons from the previous tightening cycle

History offers an indication of what is at stake if central banks are again forced into sharp tightening. During the Federal Reserve's aggressive rate hikes from March 2022 to July 2023 — when the policy rate was raised from around 0 percent to 5.25–5.50 percent in eleven steps — risky asset classes collapsed broadly.

The total value of the crypto market fell from around $3,000 billion in November 2021 to approximately $820 billion in December 2022, according to data cited by analytics firm Kaiko and The Block. Bitcoin fell from around $47,000 at the start of 2022 to below $16,000 in November of the same year. At the same time, liquidity in the market dried up: aggregate stablecoin supply — the very fuel of crypto trading — fell by around $65 billion over 18 consecutive months, according to Kaiko's analyses.

Today's market picture

Unlike in 2022, markets are currently in a risk-on phase. Bitcoin is trading around $77,200, and the Fear & Greed Index stands at 63 out of 100, indicating that investors are generally willing to take on risk. A potential new round of rate hikes from the ECB — driven by oil prices and inflation fears — would put this risk appetite to the test, given that history shows tighter monetary policy typically hits the riskiest asset classes hardest and first.

It remains to be seen whether Kocher's warning is shared by the majority of the ECB's Governing Council, or whether it remains an isolated view from one of the more inflation-wary members. Markets will likely be listening closely to upcoming statements from other central bank officials and to the development of oil prices going forward.
