ZEW Economic Sentiment Index Rises Again in August

Drivers of improved sentiment

The improved sentiment comes alongside broader signs of resilience in the German economy. Reporting around the August release noted that growth had extended for a third consecutive quarter, although the available sources rate that figure as less firmly corroborated than the sentiment reading itself.

Despite the brighter outlook, the German Economics Ministry's monthly report flagged a new supply-side worry. According to the ministry, current low water levels on important German inland waterways have raised the risk of temporary, regional material shortages, particularly in the mineral oil, chemicals, construction and steel industries.

Low water on the Rhine

The ministry put the warning in direct terms: "Mit den aktuellen Niedrigwasserständen auf wichtigen deutschen Binnengewässern ist jedoch das Risiko für temporäre, regionale Materialengpässe vor allem in der Mineralöl-, Chemie-, Bau- und Stahlindustrie gestiegen." The Rhine, Germany's busiest commercial river, is reportedly experiencing a record low water level, complicating barge traffic and the delivery of raw materials to inland factories.

Economists frequently distinguish between sentiment indicators, which capture expectations, and hard data on output, trade and industrial production. The August ZEW reading fits into the expectations category and tends to move ahead of the actual data, which is why it is watched closely by policymakers at the Bundesbank and the federal government.

How the ZEW survey fits into German data

The ZEW release is one of two closely followed German sentiment gauges published each month, alongside the ifo Business Climate Index. The ifo survey polls around 9,000 company managers, while the ZEW poll focuses on financial market professionals, giving the two indices slightly different perspectives on the economy.

Looking ahead, analysts will be watching whether the improved expectations translate into stronger investment and consumer spending. The Bundesbank's next quarterly outlook and updated forecasts from leading German economic institutes are expected later in the year and will test whether the mood matches the underlying data.

Market participants also continue to monitor monetary policy at the United States Federal Reserve, whose decisions influence global financial conditions and, by extension, German financing costs. Any change in the Fed's stance has historically been a factor cited by respondents in the ZEW survey.

For now, the August ZEW reading adds to a string of modestly positive signals for Europe's largest economy, even as the drought-driven low water on the Rhine reminds policymakers that supply-side shocks remain a near-term risk.
