Currency-area research
Research on the euro area as a currency union, including monetary transmission, investment and national fiscal adjustment.
The euro area combines a common monetary setting with economies that differ in production, finance and fiscal conditions. An aggregate can conceal divergent movements in household demand, manufacturing and construction. Research distinguishes the area-wide result from the national institutions through which adjustment occurs.
The ECB’s monetary framework operates across the currency area, while fiscal decisions and much project delivery remain national or subnational. Mortgage contracts, bank balance sheets and financing structures influence the timing of transmission. European investment funding adds another institutional layer between an allocation and completed capacity.
| Research dimension | Measure | Interpretation |
|---|---|---|
| Activity | Euro-area real GDP and expenditure | Use the area aggregate; do not add member-country values to it. |
| Prices | Harmonised Index of Consumer Prices | Distinguish the aggregate index, component measures and national weights. |
| Credit | Bank lending conditions and loan flows | Survey balances describe reported conditions, not quantities of credit. |
The ECB’s July 2026 lending survey reports both a net tightening of enterprise credit standards and a net increase in loan demand in the second quarter. These are balances of survey responses, rather than changes in the amount of lending. The monetary-transmission study examines why a common policy setting can coexist with different financing and debt-service conditions across members.
Research Report
Public support may change whether, where or when an investment takes place. This report establishes the counterfactual evidence needed to distinguish additional investment from displacement, timing changes and projects that would have proceeded without support.

This report separates sector composition, capital intensity, and working time in transatlantic productivity comparisons. Official evidence and a reproducible decomposition show why differences within industries require closer examination before aggregate gaps support policy conclusions.

Contract design and financial structure determine when monetary decisions reach borrowers. Evidence from four economies and an original debt-cohort calculation explain why financing costs can keep rising after market rates decline.

Economy Study
A common euro-area policy rate reaches borrowers through different contracts, banks, and refinancing schedules. Loan surveys and mortgage evidence show why tighter standards, rising debt payments, and changes in marginal borrowing rates can coexist.
Economy Study
National fiscal plans and European financing shape different parts of the public investment decision. A financing and execution framework separates budget commitments, payment conditions, construction, and the services delivered by completed assets.
Policy Brief
ECB decisions, lending surveys, and loan quantities describe different stages of transmission. This brief explains credit standards, qualitative net percentages, demand, and contractual timing so that changing lending conditions can be interpreted without assigning unsupported causal effects.
Policy Brief
European recovery funding links payments to milestones and targets rather than a simple total of reimbursed invoices. The brief reconciles allocations, disbursements, national execution, and service delivery, retaining the distinct deadlines and evidence relevant to the RRF's final implementation stage.
Comparative Study
American and euro-area quarterly GDP releases commonly use different rate conventions. Reconciliation of annualized and quarter-on-quarter growth establishes the basis for comparison before differences in economic performance can be assessed.
Comparative Study
Debt contracts determine when market-rate changes reach borrowers, depositors and lenders. Evidence from the United States, euro area and Japan is compared through a common repricing matrix that separates new-loan benchmarks, outstanding interest costs and scheduled cash payments.
Comparative Study
Import concentration changes with product detail, partner definitions, and regional boundaries. US, Chinese, and Eurostat compilation rules frame original examples showing how pooled diversification can conceal single-source components and how rerouting can leave production dependence unchanged.
Comparative Study
Federal Reserve, ECB, and MAS documents show why target ranges, administered rates, and exchange-rate bands need distinct treatment. Real-rate and import-price examples identify the assumptions required before comparing monetary settings or translating them into business exposure.
Data Note
An average lending rate can fall while the rate charged to every borrower category rises. A two-group decomposition identifies how changing loan volumes can reverse the interpretation of euro-area financing conditions.
Data Note
The euro area's growth rate reflects the relative size of its economies and the construction of its volume accounts. A hypothetical aggregation separates union-wide output growth from the experience of an equally weighted member.
