The toothpaste is starting to come out of the tube
In Frankfurt, the European Central Bank has drawn a firm line between the world of diplomacy and the world of monetary policy: whatever peace or conflict emerges from the Middle East, the work of taming inflation will not pause. ECB officials have signaled that rising borrowing costs reflect a deeper anxiety — that inflation expectations, once unmoored, become nearly impossible to recapture — and that this internal risk outweighs any geopolitical reprieve. The bank watches a continent carrying half a trillion euros in corporate debt toward refinancing, markets vulnerable to sudden correction, and a price spiral it refuses to let take hold.
- The ECB has declared its rate-hiking campaign immune to geopolitical developments, including any Iran peace deal, placing inflation control above all other considerations.
- Officials warn that an Iran conflict poses systemic dangers beyond those of the Ukraine war, threatening to destabilize the €500B+ in European corporate debt coming due for refinancing.
- Inside the bank, a quiet alarm is sounding: inflation expectations are beginning to slip their anchor, and once they do, the cost of recovery rises sharply.
- The ECB is simultaneously warning of potential sharp asset price corrections — a risk its own tightening policy helps create, yet one it judges less dangerous than unchecked inflation.
- European borrowers — corporations, governments, households — are being told to expect higher debt costs well into the future, with no near-term exit from the tightening cycle in sight.
The European Central Bank has sent an unambiguous message: interest rates will continue rising, and no development on the geopolitical stage — including a peace agreement with Iran — will alter that course. Speaking to the Financial Times, ECB officials made clear that monetary tightening is driven by inflation, and inflation alone.
The bank is watching two converging pressures with particular concern. An Iran conflict, officials argue, carries systemic risks that exceed even those posed by the war in Ukraine — risks that are harder to contain and more globally entangled. Adding urgency to that picture is the roughly €500 billion in European corporate debt approaching refinancing in an environment of rising rates and market volatility.
But the deeper anxiety is internal. ECB officials have reached for a telling metaphor: the toothpaste is beginning to come out of the tube. Inflation expectations, which had shown signs of stabilizing, are once again drifting. If workers and businesses begin to price persistent inflation into their behavior, the bank's task becomes exponentially harder. That is the scenario the ECB is most determined to prevent.
To that end, the bank is holding firm to its one reliable instrument: the interest rate. Higher borrowing costs slow demand and cool prices, even as they burden businesses, households, and governments. Officials have also warned of the risk of a sharp market correction — a tension the tightening campaign itself helps create — but they judge the inflation threat to be the more urgent danger.
The signal to European borrowers is clear: this cycle is not ending soon. Peace or conflict abroad will not change the ECB's calculus. Its gaze remains fixed on domestic price stability, and everything else — including the fate of negotiations half a world away — is secondary to that mission.
The European Central Bank has made its position clear: interest rates will keep climbing, and no peace deal with Iran will change that calculation. In recent comments to the Financial Times, ECB leadership, including officials like Wunsch, laid out a straightforward message—monetary tightening continues because inflation remains the governing concern, regardless of what happens on the geopolitical stage.
The backdrop is a continent caught between two pressures. On one side sits the threat of renewed conflict in the Middle East, a development the ECB views with particular alarm. Unlike the Ukraine war, which had largely defined European risk thinking for the past two years, an Iran conflict carries what officials describe as factors that could ripple across the global economy in ways that are harder to contain or predict. The ECB has identified specific vulnerabilities: roughly half a trillion euros in European corporate debt is coming due and will need to be refinanced. In a period of rising rates and market volatility, that becomes a genuine stress point.
Yet the bank's concern runs deeper than geopolitics alone. Internally, ECB officials are wrestling with a metaphor that captures their anxiety: the toothpaste is starting to come out of the tube. What they mean is that inflation expectations, which had begun to stabilize, are showing signs of becoming unmoored again. The risk that price pressures will detach from the bank's targets—that workers and businesses will begin to expect persistent inflation and price their behavior accordingly—is rising. That is the scenario the ECB fears most, because once expectations shift, controlling inflation becomes exponentially harder.
This concern has sharpened the bank's focus on one tool: the interest rate. By continuing to raise borrowing costs, the ECB aims to keep inflation in check and anchor expectations before they drift further. The logic is straightforward, even if the collateral damage is real: higher rates slow spending, cool demand, and theoretically bring prices back under control. It is a blunt instrument, and it carries costs—businesses struggle to finance operations, households delay purchases, growth slows. But from the ECB's vantage point, the alternative—losing control of inflation—is worse.
The bank has also sounded a broader alarm about financial markets themselves. Officials have warned of the risk of a sharp correction in asset prices, a sudden repricing that could cascade through the system. This warning sits in tension with the rate-hiking campaign: tighter monetary policy tends to pressure asset valuations, which is part of how it works, but a disorderly market correction could trigger instability that even rate hikes cannot easily manage. The ECB is essentially saying it sees multiple risks converging—geopolitical, inflationary, and financial—and it is proceeding with rate increases anyway because it judges the inflation risk to be the most urgent.
What this means in practice is that European borrowers, from corporations to governments to households, will face higher debt service costs for the foreseeable future. The ECB is signaling that this tightening cycle is not near its end. Peace in Iran, or continued conflict there, will not alter that trajectory. The bank's focus remains fixed on the domestic inflation picture and the stability of expectations. Everything else, including the geopolitical backdrop, is secondary to that mission.

The risk that inflation will become unanchored is increasing— ECB officials
A Conversa do Hearth Outra perspectiva sobre a história
Why does the ECB care so much about an Iran conflict if it's thousands of miles away?
Because half a trillion euros of European corporate debt needs to be refinanced soon. If markets seize up or become volatile, companies can't roll over that debt at reasonable rates. It's not about Iran itself—it's about what Iran does to European financial plumbing.
But couldn't a peace deal actually help? Wouldn't that reduce uncertainty?
Theoretically, yes. But the ECB is saying it doesn't matter for their rate decisions. They're focused on inflation expectations. They see signs that people are starting to expect prices to stay high, and that's the real danger.
What's this about toothpaste coming out of a tube?
It's how ECB officials describe inflation expectations becoming unanchored. Once people believe inflation will persist, they demand higher wages, businesses raise prices preemptively, and you get a self-fulfilling cycle. Getting it back in the tube is much harder than preventing it from coming out.
So they're raising rates even though it could hurt the economy?
Yes. They're betting that controlling inflation now prevents something worse later. But they're also warning about sharp market corrections, which suggests they know this tightening could trigger instability.
Is there a way out of this for European businesses?
Not in the near term. The ECB has signaled this cycle continues regardless of external events. Businesses have to adapt to higher borrowing costs as a new reality.
