The ECB is strangling eurozone investment to fight a fever monetary policy cannot cure.

The July lending data documents it. Bank loans to businesses collapsed to €22 billion, down from €27 billion in June and €34 billion in May — a one-third drop in two months. Long-maturity lending — the credit that funds factories, equipment, the long-gestation projects that drive future productivity — fell to €9 billion from €21 billion. A 57% collapse in a single month. Businesses are not just borrowing less; they are refusing to commit to the future.

The ECB lifted its key rate to 2.25% in June, as this column noted at the time. The rate hike passed through to lending exactly as the theory predicts. Borrowing got expensive. Borrowing stopped.

Who absorbs the €9 billion collapse. Construction crews that would have poured foundations for the next factory expansion are idle. Mid-cap manufacturers — the 100-to-500-employee firms that live or die on bank credit rather than bond markets — are discovering that the term loans they were counting on have quietly disappeared. In the southern periphery — Spain, Italy, the Greek industrial base — where the bank channel carries a heavier share of business finance than in Frankfurt or Paris, the same print lands harder. These are not abstract productive-base figures. They are wage packets that will not be paid, capex orders that will not be placed, apprentice classes that will not be hired this autumn.

The diagnosis is direct. The ECB is tightening into a credit crunch it created, while inflation pushes higher on an energy channel monetary policy cannot reach. The U.S.-Iran war has pushed crude higher, and the Strait of Hormuz — not the cost of capital — is the binding constraint on eurozone inflation. Two forces, both tightening, neither offsetting the other. Tightening credit will not drill more oil or reopen the strait. It will, however, make sure that when the energy shock fades, the eurozone has nothing to show for it but shuttered factories and deferred investment.

Long-dated loan demand is not a coincident indicator; it is a leading indicator of investment-spending decisions being deferred, industrial projects shelved, long-cycle investments cancelled. The €9 billion print in July — barely half of June’s pace, roughly a quarter of May’s — is the kind of data that precedes recession by two to three quarters.

This is the trap the ECB has built for itself. A pause now would be a confession that the policy is too tight. A hike doubles down on a policy whose effect is only beginning. The central bank has lost the optionality of pausing without admitting the policy was wrong from the start. The institutional reflex is well-documented. The ECB hiked in July 2008, six weeks before the most violent re-pricing of European credit since the launch of the currency. It hiked twice in 2011, into a sovereign-debt crisis the rate path made worse. The pattern recurs because the institutional reflex — defend the inflation target against the headline number — overrides the reading of the credit channel until the channel itself breaks.

The policy that fights an energy shock is energy policy, not interest-rate policy. Until the ECB recognizes that, the workers and manufacturers in the productive base pay the price. The July data is on the desk. The next meeting is the test.
