€STR

The euro short-term rate (€STR) is the official overnight benchmark interest rate for the euro area, reflecting the wholesale unsecured overnight borrowing costs of euro area banks based on actual transactions.^[1] It is administered by the European Central Bank (ECB) and published daily at 08:00 CET on each TARGET2 business day, using data from transactions conducted and settled on the previous TARGET2 business day.^[1] Developed in response to global reforms aimed at enhancing the robustness of interest rate benchmarks following financial scandals, the €STR was recommended by the Working Group on Euro Risk-Free Rates and officially launched by the ECB on 2 October 2019, with its first rate reflecting activity from 1 October 2019.^[2] It replaced the Euro Overnight Index Average (EONIA), the original calculation of which ceased on 30 September 2019, after which it was published as €STR plus an 8.5 basis point spread until full discontinuation on 3 January 2022.^[2] The ECB provides pre-€STR historical data up to 30 September 2019 for continuity in financial analysis and contract referencing.^[2] The €STR is calculated as a volume-weighted trimmed mean of unsecured overnight borrowing transactions reported by euro area banks under the Eurosystem's Money Market Statistical Reporting (MMSR) framework, which excludes the highest and lowest 25% of rates by volume to reduce the impact of outliers and ensure representativeness; as of July 2025, the panel was expanded to include 24 additional reporting agents.^[3] This methodology adheres to International Organization of Securities Commissions (IOSCO) principles for financial benchmarks, emphasizing transaction-based data from a broad panel of reporting agents to capture genuine market conditions.^[2] Governance is overseen by an ECB €STR Oversight Committee under the €STR Guideline (ECB/2019/19), with policies ensuring transparency, impartiality, and free public access to the rate without any commercial interests.^[2] As the euro's primary risk-free rate, the €STR underpins a wide range of financial instruments, including derivatives, cash loans, bonds, and repurchase agreements, serving as a reference for pricing, valuation, and risk management in euro-denominated markets.^[1] The ECB also publishes compounded €STR averages over standard tenors (e.g., 1 week to 12 months) and an index to facilitate its use in longer-term contracts, supporting the transition away from older benchmarks like EURIBOR in line with EU regulations.^[2] Its reliability has made it integral to monetary policy transmission and market stability in the euro area.^[4]

Background and History

Definition and Purpose

The euro short-term rate (€STR) is a benchmark interest rate that reflects the wholesale euro unsecured overnight borrowing costs of euro area credit institutions, based on actual transactions conducted and settled on TARGET2 business days.^[2] It represents the average rate at which euro area banks borrow funds overnight from each other without collateral, providing a direct measure of the euro money market's overnight segment.^[2] Published daily by the European Central Bank (ECB), €STR serves as a foundational reference for the euro area's short-term funding conditions.^[1] The primary purpose of €STR is to function as a risk-free overnight interest rate (RFR) benchmark, designed to replace less robust interbank offered rates (IBORs) such as EONIA amid global efforts to reform interest rate benchmarks following the 2008 financial crisis and subsequent scandals involving rate manipulation, like those affecting LIBOR.^[2] Unlike survey-based or estimated rates, €STR is fully transaction-based, ensuring greater stability, transparency, and resistance to manipulation while adhering to international standards set by the International Organization of Securities Commissions (IOSCO).^[2]^[5] This reform-driven initiative addresses vulnerabilities exposed in traditional benchmarks, promoting a more reliable foundation for euro area financial markets.^[4] €STR plays a critical role in pricing and valuing euro-denominated financial instruments, including derivatives such as overnight index swaps (OIS), variable-rate loans, and securities, where it provides a consistent overnight reference rate.^[4] It was designated as the preferred RFR for the euro area by the Working Group on Euro Risk-Free Rates on 13 September 2018, with the ECB tasked with its publication to support seamless market adoption.^[6] This endorsement underscores its status as the euro's core risk-free benchmark, facilitating the transition away from legacy rates like EONIA.^[6]

Development and Launch

In response to global concerns over the reliability of interbank offered rates following financial scandals and regulatory reforms, the European Central Bank (ECB), along with the European Securities and Markets Authority (ESMA), the European Commission, and the Belgian Financial Services and Markets Authority (FSMA), established the Working Group on Euro Risk-Free Rates in September 2017.^[7] This industry-led group, chaired by private sector representatives, was tasked with identifying robust, transaction-based risk-free rates (RFRs) to replace vulnerable benchmarks like EONIA, prioritizing rates grounded in actual market activity to enhance transparency and resilience.^[6] Following extensive consultations and analysis of potential candidates, the working group unanimously recommended the euro short-term rate (€STR) on September 13, 2018, as the preferred euro RFR.^[8] The €STR was selected for its basis in unsecured overnight borrowing transactions reported under the ECB's existing Money Market Statistical Reporting (MMSR) framework, which captures wholesale euro unsecured activity among euro area banks, ensuring a broad and representative dataset without reliance on submissions or estimates.^[8] This choice addressed the need for an overnight rate aligned with the ECB's monetary policy operations, drawing from over 50 reporting banks to reflect genuine borrowing costs.^[4] To facilitate market preparation and testing, the ECB began publishing preliminary "pre-€STR" figures in April 2019, derived from voluntary transaction data submissions beyond the core MMSR requirements, allowing stakeholders to familiarize themselves with the rate's behavior and integrate it into systems.^[9] Concurrently, mandatory MMSR reporting for unsecured overnight transactions was expanded starting in July 2019, incorporating additional banks to bolster data volume and representativeness ahead of the official rollout.^[10] These steps were crucial amid challenges in the unsecured market, where ample central bank liquidity had reduced interbank lending volumes, potentially limiting the dataset's depth; the ECB mitigated this by leveraging its regulatory authority to enforce comprehensive reporting and by focusing on high-quality, verifiable trades.^[4]^[11] The €STR officially launched on October 2, 2019, with its inaugural publication reflecting borrowing transactions from the previous day, October 1, 2019, and disseminated daily at 08:00 CET via the ECB's Data Portal.^[12] This marked a pivotal shift toward transaction-based benchmarks in the euro area, with the rate serving as the basis for the recalibrated EONIA methodology from 2 October 2019, adding a fixed 8.5 basis point spread to align the legacy rate during its phase-out.^[13] The full transition culminated on January 3, 2022, when EONIA was discontinued entirely, cementing €STR as the euro area's primary overnight RFR.^[14] Subsequent expansions to the MMSR reporting panel occurred, with 24 additional banks added in July 2024 and another 24 in July 2025, to further improve the €STR's representativeness.^[15]

Calculation and Methodology

Data Sources and Reporting

The €STR is calculated using transaction-level data on unsecured overnight borrowing in the euro money market. This includes both interbank lending and non-interbank transactions, such as deposits from corporates and other non-bank entities classified as wholesale under regulatory frameworks like Basel III's Liquidity Coverage Ratio (LCR).^[3]^[10] The data is sourced through the Money Market Statistical Reporting (MMSR) regime, established under Regulation (EU) No 1333/2014 (ECB/2014/48), which mandates daily reporting from euro area credit institutions. This regime became mandatory for the 50 largest euro area credit institutions effective July 30, 2019, coinciding with the launch of €STR publications, although MMSR collections began earlier in 2016 for broader money market segments.^[3]^[16] Reporting agents must submit details of all euro-denominated unsecured overnight fixed-rate deposit transactions exceeding €1 million that settle on TARGET2, the euro area's real-time gross settlement system. These submissions are required by 07:15 CET on the business day following the transaction date, with the European Central Bank (ECB) and national central banks (NCBs) performing quality checks and enforcing compliance through supervisory measures.^[3]^[10] The coverage focuses exclusively on unsecured transactions, including any repurchase agreements structured as unsecured (though such cases are rare, as repos typically involve collateral). Excluded are secured transactions, deals in foreign currencies, and overnight borrowings with central banks for monetary policy purposes.^[3]^[10] As of December 2025, the €STR typically draws from 45-50 active reporting agents, with daily unsecured overnight volumes ranging from €60 billion to €65 billion; for instance, on December 9, 2025, 48 active banks reported 869 transactions totaling €65.436 billion. In July 2025, 24 additional banks were integrated into the reporting population starting July 2, increasing the total to approximately 71 institutions and improving the robustness and representativeness of the benchmark, with full use in €STR calculations from July 1, 2025.^[1]^[15]

Computation Process

The €STR is calculated as a volume-weighted trimmed mean of the interest rates from eligible unsecured overnight euro money market transactions reported under the Money Market Statistical Reporting (MMSR) framework.^[3] This approach ensures the rate reflects the borrowing costs of euro area banks while mitigating the influence of outliers by excluding the highest and lowest portions of transaction volumes.^[17] The computation begins with the collection of all relevant transaction data from the previous TARGET2 business day, including interest rates and volumes for overnight unsecured fixed-rate deposit transactions exceeding €1 million, as mandated by Regulation (EU) No 1333/2014.^[3] These data are sorted in ascending order by interest rate, with transactions aggregated at each distinct rate level to facilitate the trimming process.^[3] Next, the top and bottom 25% of the total eligible volume are trimmed—meaning the highest and lowest 25% of volumes are excluded—to focus on the central 50% of the distribution and enhance the rate's stability.^[3] If a rate level spans the trimming threshold, volumes are apportioned pro rata to ensure precise exclusion.^[3] The €STR is then derived as the volume-weighted average of the rates in the remaining trimmed set, where each transaction's rate is weighted by its corresponding volume. The formula is given by:

€STR = \frac{\sum_{i \in T} (r_i \cdot v_i)}{\sum_{i \in T} v_i}

where T denotes the set of transactions after trimming, r_i is the interest rate of transaction i, and v_i is its volume.^[3] This mean is rounded to three decimal places and expressed in percentage terms. For instance, if the trimmed transactions include volumes at rates of 3.50% (€100 million), 3.52% (€150 million), and 3.55% (€200 million), the €STR would be (3.50 \times 100 + 3.52 \times 150 + 3.55 \times 200) / (100 + 150 + 200) = 3.523\%.^[3] The calculation is performed daily by the European Central Bank (ECB) and published at 08:00 CET on the following TARGET2 business day.^[3] In edge cases of insufficient data—such as fewer than 20 reporting banks or where the top five banks account for 75% or more of the total volume—a contingency procedure is activated, using the previous day's €STR adjusted for any changes in the ECB's key interest rates and incorporating any available new transactions.^[3] Automated filters initially exclude anomalous data, which can be reintegrated upon bank verification before finalization.^[17]

Characteristics and Publication

Key Features

The €STR is a backward-looking benchmark rate with an overnight tenor, reflecting actual wholesale euro unsecured borrowing transactions conducted and settled on the previous TARGET2 business day rather than forward-looking estimates.^[2] This design ensures it captures genuine market conditions from the prior day, with publication occurring daily at 08:00 CET.^[3] As the euro area's risk-free rate, €STR is derived from arm's-length unsecured overnight deposits exceeding €1 million among euro area credit institutions, resulting in low credit and operational risk exposure.^[2] Its focus on transactions within the euro area banking sector minimizes counterparty risks, aligning with IOSCO principles for robust benchmarks.^[3] €STR demonstrates strong representativeness by encompassing a broad spectrum of euro money market segments, with contributions from up to 69 banks as of mid-2024, and further expanded by 24 banks effective 2 July 2025.^[15]^[18] The top five banks typically account for around 40% of total volume, indicating diversified participation without over-reliance on a few entities.^[1] For instance, as of late 2025, the 25th and 75th percentile rates hovered between 1.90% and 1.95%, illustrating the rate's tight clustering around the median.^[1] The rate's resilience is enhanced by a volume-weighted trimmed mean calculation, which excludes the highest and lowest 25% of transactions to mitigate outlier influences.^[3] Daily volumes have generally been above €50 billion since 2021, with recent figures stable around €60 billion as of 2025, supporting consistent and reliable computation even during market stress.^[3]^[19] Transparency is a core attribute, with the full methodology and policies publicly available and administered by the ECB to eliminate conflicts of interest.^[2] From its launch in 2019 through 2025, the €STR has averaged approximately 1.22%, closely tracking ECB monetary policy adjustments.^[20]

Publication and Accessibility

The €STR is published daily at 08:00 CET on each TARGET2 business day, reflecting the unsecured overnight borrowing transactions conducted and settled on the previous TARGET2 business day.^[21] This schedule ensures timely availability for market participants, with a revised rate issued by 09:00 CET if errors exceeding two basis points are identified.^[21]^[4] The rate is disseminated free of charge through the ECB's Data Portal, with no licensing fees required for its use.^[1] Accompanying data includes the €STR value itself, total transaction volume, number of transactions and active reporting banks, percentile ranges (such as the 25th and 75th percentiles of individual bank rates), and the volume share of the five largest active banks to indicate market concentration.^[1] For instance, as of November 2025, the €STR stood at 1.930% for the reference date of 11 November, with a total volume of €63,257 million across 848 transactions from 47 active banks; the 25th percentile was 1.90%, the 75th was 1.95%, and the top five banks accounted for 41% of the volume.^[1] Historical €STR data is available from its launch on 2 October 2019, with pre-€STR rates published retrospectively from 1999 to provide long-term continuity for users transitioning from prior benchmarks.^[1] Access is facilitated via the ECB Data Portal, supporting API queries through the SDMX 2.1 RESTful web service, bulk downloads in formats like CSV and XML, and direct integration into financial platforms such as Bloomberg and Refinitiv for real-time retrieval.^[22]^[23]^[24]

Applications and Comparisons

Usage in Financial Instruments

The €STR serves as the primary reference rate for the floating leg in overnight index swaps (OIS), where it has largely replaced EONIA following the completion of the transition in January 2022.^[25] It is also widely used in futures contracts, such as those traded on Eurex and ICE, to hedge short-term interest rate exposure, with open interest in €STR futures reaching over €1.9 trillion notional equivalent in May 2025.^[26] In repo agreements, €STR benchmarks the pricing of overnight secured lending transactions, facilitating liquidity management in the euro money markets.^[2] In lending and capital markets, €STR is integrated into variable-rate loans, bonds, and mortgages, typically structured as €STR plus a credit spread to reflect borrower-specific risk. For instance, corporate loans and adjustable-rate mortgages in the euro area increasingly reference compounded €STR to align interest payments with actual overnight borrowing costs.^[27] This approach ensures that financing costs remain closely tied to risk-free market conditions. As a fallback rate, €STR is incorporated into legacy contracts originally linked to EONIA or Euribor, particularly after EONIA's discontinuation in January 2022 and in scenarios where Euribor faces cessation or material changes.^[28] The International Swaps and Derivatives Association (ISDA) has defined €STR-based fallback provisions for these instruments to maintain continuity in derivatives and cash products.^[29] In euro area payment systems like TARGET2 and collateral management frameworks, €STR underpins the valuation of intraday and overnight positions, as well as the pricing of collateral mobilized in Eurosystem credit operations.^[30] This role supports efficient liquidity allocation and risk mitigation across central bank facilities. Adoption of €STR has accelerated, with €STR-linked OIS accounting for nearly 86% of total euro OIS traded notional in the EU by 2024, and continuing to dominate new derivatives issuance.^[29] By mid-2025, quarterly cleared volumes for euro IRS and OIS exceeded €58 trillion notional, reflecting €STR's central position in the market.^[31] A specific example of its application is the compounding of €STR in arrears for longer-term instruments, such as interest rate swaps, where the effective rate is determined retrospectively using daily €STR observations over the accrual period, ensuring precise alignment with realized borrowing costs.^[27]

Relation to Other Benchmark Rates

The €STR replaced the Euro Overnight Index Average (EONIA) as the primary risk-free rate (RFR) for the euro area, following recommendations from the Working Group on Euro Risk-Free Rates. Launched by the European Central Bank (ECB) in October 2019, the €STR became the standard overnight benchmark upon EONIA's discontinuation on 3 January 2022. During the transition period from October 2019 to December 2021, EONIA was recalibrated and calculated as the €STR plus a fixed spread of 8.5 basis points to ensure continuity and minimize market disruptions.^[25] In contrast to the Euro Interbank Offered Rate (Euribor), the €STR is a backward-looking, transaction-based rate reflecting actual unsecured overnight borrowing costs among eurozone banks, making it nearly risk-free as it excludes credit and term premiums. Euribor, administered by the European Money Markets Institute (EMMI), is forward-looking, derived from panel bank submissions estimating borrowing costs for tenors ranging from one week to 12 months, and incorporates bank credit risk, rendering it sensitive to interbank lending conditions. This fundamental difference positions the €STR as a more robust, data-driven alternative for risk-free applications, while Euribor remains relevant for credit-sensitive products.^[28] Globally, the €STR aligns with other major RFRs as an overnight, transaction-based benchmark, though it differs in collateralization: it is unsecured like the Sterling Overnight Index Average (SONIA) for GBP, capturing wholesale unsecured lending, whereas the Secured Overnight Financing Rate (SOFR) for USD is secured by Treasury collateral in the repo market. All three rates emphasize actual transactions to enhance transparency and resilience post-LIBOR reforms, with the €STR's low-risk profile stemming from its focus on high-volume euro money market activity reported under the Money Market Statistical Reporting regulation.^[4] To address needs for forward-looking rates, FTSE Russell (part of LSEG) launched a prototype for the Term €STR in October 2022, offering tenors such as 1-month and 3-month based on committed quotes and executed trades in €STR overnight index swaps (OIS), rather than direct transactions. Unlike the spot €STR, this term structure derives expectations from observable OIS market data, ensuring compliance with EU benchmark regulations; the Working Group published recommendations and a comparative table for term €STR providers in 2023 for use in fallbacks and specific lending products like retail mortgages and corporate loans.^[32]^[24] The transition to €STR has been supported by the International Swaps and Derivatives Association (ISDA), which incorporated €STR-based fallback provisions into its standard documentation in 2021 for derivatives referencing Euribor or EUR LIBOR, applying spread adjustments to align with RFR characteristics. These fallbacks have facilitated a smooth shift for legacy contracts, with minimal market disruptions observed by 2022 and continued adoption through 2025, as evidenced by increasing €STR usage in euro interest rate derivatives.^[25]^[33]

Governance and Oversight

Administration by the ECB

The European Central Bank (ECB) serves as the administrator of the €STR, bearing overall responsibility for its calculation, publication, and data validation processes. This role is primarily managed through the ECB's Statistics Department, which collects and processes daily confidential Money Market Statistical Reporting (MMSR) data from euro area banks, and the Monetary Policy Department, which oversees governance and alignment with broader ECB objectives.^[2] Four national central banks—Deutsche Bundesbank, Banco de España, Banque de France, and Banca d’Italia—provide operational support for data collection.^[2] Operationally, the ECB conducts daily reconciliation and quality checks on MMSR data to validate transactions and ensure accuracy in €STR computation, applying technical validations to identify and correct discrepancies. Annual volume assessments, detailed in the ECB's €STR Annual Methodology Reviews, evaluate transaction volumes—such as the €55 billion average in 2024—to confirm the rate's representativeness and robustness against market fluctuations.^[34]^[3] To engage stakeholders, the ECB holds public consultations, lasting at least six weeks, for any material methodology changes, and provides €STR data freely via its website, MID platform, and Data Portal to encourage widespread adoption.^[2] Since 2020, the ECB has ensured €STR compliance with the IOSCO Principles for Financial Benchmarks through a self-assessment and external audit, maintaining governance, quality, and accountability standards.^[35]^[36]

Regulatory and Methodological Framework

The €STR operates under a robust regulatory framework aligned with the EU Benchmarks Regulation (BMR), which entered into force in 2018 and mandates stringent requirements for benchmark administrators to ensure integrity, reliability, and transparency. As a critical benchmark under the BMR, the €STR is administered by the European Central Bank (ECB), which was designated as its administrator upon the rate's launch on 2 October 2019, reflecting the ECB's role as a public authority in providing a risk-free rate for the euro area. This designation leverages exemptions for public sector administrators while ensuring full compliance with BMR provisions on governance, data quality, and oversight. Additionally, the ECB has confirmed the €STR's adherence to the International Organization of Securities Commissions (IOSCO) Principles for Financial Benchmarks through a self-assessment and external independent assurance report published in September 2020, covering aspects such as input data controls, calculation processes, and conflict-of-interest management.^[2]^[37]^[38] The methodological framework for the €STR is governed by ECB Guideline (EU) 2019/1265, which outlines the rate's calculation as a volume-weighted trimmed mean of overnight unsecured borrowing transactions reported under the Money Market Statistical Reporting (MMSR) regime. To maintain robustness, the ECB conducts annual methodology reviews, incorporating consultations with stakeholders to assess performance, market developments, and potential adjustments. The 2023 review, covering the period from October 2022 to September 2023, tested the existing 25% trimming level—applied to exclude the highest and lowest quartile of transactions to mitigate outliers—and confirmed its adequacy in limiting volatility to approximately 0.2 basis points amid the ECB's policy rate hikes, with no changes implemented. Similarly, the 2024 review reaffirmed the methodology's stability during the subsequent rate stabilization phase, including the integration of 24 new reporting banks starting July 2024, with the 2025 review published on 30 October 2025 further confirming no changes to the trimming level or methodology amid ongoing stability.^[39]^[40]^[34]^[41] Contingency provisions safeguard the €STR's continuity in cases of data disruptions, triggered if fewer than 20 banks report data or if five banks account for 75% or more of total volume, ensuring against undue concentration or insufficiency. In such scenarios, the rate combines the previous TARGET2 business day's €STR with available current-day transactions on a volume-weighted basis; if no transactions occur, it defaults to the prior day's rate, adjusted for any changes in ECB key policy rates, such as the deposit facility rate (for rates below the interest rate corridor) or the marginal lending facility rate (for rates above it). This adjustment mechanism ties the fallback directly to ECB monetary policy signals, maintaining alignment with underlying market conditions. All methodological changes or contingency activations are publicly disclosed promptly by the ECB to promote transparency and user confidence.^[3]^[2] On the international front, the €STR aligns with global efforts to reform interest rate benchmarks, as recommended by the Financial Stability Board (FSB) in its 2014 report following the LIBOR scandals, positioning it as the euro area's recommended risk-free rate (RFR) alongside peers like SOFR and SONIA. The ECB supports these initiatives through participation in FSB working groups, ensuring the €STR's methodology contributes to cross-border financial stability. External audits further bolster credibility; the ECB appoints independent auditors to evaluate compliance with IOSCO principles and internal controls, with the 2020 assurance report verifying the framework's effectiveness in governance and data handling, and periodic reviews continuing thereafter.^[42]^[4]^[38] The €STR has remained unaffected by Brexit, as its data inputs are confined to euro area banks under MMSR, insulating it from UK market disruptions that impacted legacy benchmarks like EONIA. In 2025, amid the aftermath of elevated ECB policy rates peaking at 4% in 2023 before easing to 2%, the €STR demonstrated resilience by incorporating data from the expanded reporting panel following the addition of 24 new banks in July 2024, sustaining stable publication and low volatility around 1.93% without triggering contingencies.^[9]^[2]^[40]
