According to the ifo Institute, the Business Climate Index fell sharply in April 2026 to 84.4 points (from 86.3 in March), marking its lowest level since the COVID lockdowns in May 2020.

Companies assessed both their current situation and future expectations significantly worse, driven largely by the energy price shock from the Iran conflict.

The decline was broader than expected and affected all major sectors: manufacturing, services, trade, and construction.

This deterioration coincides with growing simultaneous pressure on investment, production, and growth, as reported by Handelsblatt on 15 April 2026.

Industrial production remains weak, many companies are scaling back or postponing investments due to high energy costs and uncertainty, and economic growth forecasts for 2026 have already been halved to around 0.5%.

The negative feedback loop between these three factors is pushing the German economy deeper into stagnation.

Economists and the ifo Institute explicitly cite the fallout from the Iran war (involving US/Israeli actions and resulting disruptions in the Middle East) as the key driver. It has pushed oil and gas prices significantly higher, reversing earlier hopes of a gradual recovery. Energy prices for consumers (fuel and heating oil) surged, contributing to a jump in inflation to 2.7% year-on-year in March 2026 (up from 1.9% in February).

Underlying structural problems

This is not just a temporary geopolitical hit. Germany has faced years of near-stagnation:

• Weak productivity growth
• Demographic headwinds (aging population and shrinking workforce)
• High energy costs
• Loss of competitiveness in manufacturing and exports (especially vs. China and the US)
• Heavy bureaucracy and regulatory burdens

These factors have kept potential growth very low. The latest shock has amplified existing weaknesses in domestic demand, investment, and export markets.

Chancellor Friedrich Merz’s government has announced substantial fiscal stimulus (infrastructure, defense, and adjustments to the debt brake).

However, in response to the energy shock, the government has already halved its 2026 GDP growth forecast to just 0.5% (from 1.0% previously) and cut the 2027 forecast to 0.9%.

Inflation projections have been raised. Leading economic institutes now cluster around 0.5–0.6% growth for 2026.

The Handelsblatt coverage around mid-April 2026 (including articles from ~15 April) highlighted exactly this: the pressure on investment, production, and growth is intensifying simultaneously and feeding into each other.

The economic situation in April 2026:

Industrial production has been weak or slightly declining. In February 2026 it fell 0.3% month-on-month, and the average for January/February was already below Q4 2025 levels. Even before the full impact of the Iran conflict, the economy was on track for a weak or contracting Q1. Many companies (around 35% in some surveys) expect production to decline further in 2026.

Investment (especially equipment and private investment) faces strong headwinds. The government had to nearly halve its forecast for Bruttoanlageinvestitionen (gross fixed capital formation) in the latest projection. Many firms remain reluctant: almost 40% plan to invest less this year. Private investment has largely stagnated since 2015 and is now trending downward in real terms, while public spending is increasingly propping up overall demand. High energy costs, uncertainty from the Middle East conflict, and structural burdens (regulation, labor costs, competitiveness issues) are causing companies to postpone or cancel projects.

Growth is being revised sharply lower. The federal government cut its 2026 GDP forecast from 1.0% to 0.5%, with inflation now expected at 2.7%. Leading institutes are in a similar range (0.6–0.7%). The recovery that many hoped for after the 2023–2024 recession has been repeatedly postponed. Net exports are turning negative or flat, private consumption is growing only modestly, and the economy is increasingly dependent on state spending to avoid outright contraction.

Germany’s core problem remains structural: low productivity growth, demographic decline, persistently high energy prices (post-2022 and now again), loss of industrial competitiveness (especially in autos, chemicals, and machinery), and a heavy regulatory/bureaucratic burden. The latest external shock has simply exposed and amplified these vulnerabilities.

Fiscal stimulus under the Merz government is intended to counteract this by boosting public investment and infrastructure. However, economists note that the multiplier effect is often below 1 when structural problems are not addressed, and implementation takes time.

Without meaningful reforms — simplifying regulation, securing competitive energy supply, improving labor market flexibility, and enhancing innovation incentives — the risk of permanent low-growth stagnation remains elevated.
