The euro area's latest October purchasing managers' index (PMI) readings offered little encouragement about the health of the region's economy, painting a picture of slowing growth at a time when inflation pressures are refusing to fade. PMIs are survey-based gauges of business activity compiled from responses by purchasing managers in the manufacturing and services sectors, with readings above 50 signaling expansion and below 50 signaling contraction — a framing that makes them some of the most closely watched early indicators of an economy's direction. That combination presents the European Central Bank (ECB) with an uncomfortable headache as its next policy decisions approach.

The data showed disappointing results from both the manufacturing and services sectors, with services activity slowing particularly markedly — a notable shift given that services had been the more resilient side of the euro area economy while manufacturing struggled. Much of the weakness was attributed to France, where business activity returned to contraction in October, slipping back below the 50 mark. Germany continued to hold up comparatively better, but the broader slowdown across the region is becoming increasingly difficult to ignore heading into the final quarter of the year.

According to the PMI report (https://investinglive.com/news/eurozone-october-pmi-misses-estimates-as-growth-slows-keeping-ecb-rate-hike-dilemma-alive/), while business activity showed signs of cooling, price pressures have not followed suit. Businesses continued to grapple with elevated cost pressures, and manufacturers saw a sharp acceleration in input prices in October, largely driven by higher energy costs — the steepest increase since May.

The one consolation was that output price inflation eased slightly on the month. That, however, could also suggest businesses are finding it harder to pass costs on to consumers.

The resulting mix leaves the ECB facing a genuine dilemma. PMI surveys are watched closely by central banks precisely because they offer a timely read on both growth momentum and price pressures, and this month's combination sharpens the growth-versus-inflation trade-off at the heart of the rate decision. Traders are pricing in roughly 90% odds that the central bank will leave rates unchanged at next week's meeting. Looking further ahead, traders still assign around 68% odds of a rate hike in December, the final month of the year.

For now, inflation pressures remain the most pressing concern for policymakers. Yet the latest data also serve as a reminder that the euro area economy is not in the best shape to withstand further tightening. France is the major economy struggling the most amid fiscal worries and concerns surrounding public finances, and the risk of spillover effects to the rest of the region should not be discounted.

Against that backdrop, the key question is not so much whether the ECB will hold rates next week — that is largely seen as a done deal — but whether policymakers can afford to keep raising rates if growth continues to lose momentum while higher energy costs squeeze businesses and households and fiscal worries mount across the region.
