TABLE OF CONTENTS

Overview

Despite a challenging financial, economic and geopolitical environment, the Council of Europe Development Bank (CEB, or the Bank) maintained a sound financial position in the first half of 2026. Core earnings continued on a positive trend, the balance sheet remained strong and no defaults or late payments were recorded during the period.

Income Statement

The Bank’s net profit reached €70.1 million in the first half of 2026, increasing by 19.4% compared to €58.7 million in the first half of 2025. Core earnings, which represents net profit excluding financial instruments valuations and cost of risk, reached €70.0 million in the first half of 2026, showing a positive trend (7.5%) compared to €65.1 million in the first half of 2025. Net interest margin increased by €6.8 million primarily driven by an increase in interest income from investment in long-term securities at amortised cost, while the interest received from loans and liquid assets was partially offset by interest paid on refinancing, in line with interest rate and margin developments.

Two volatile elements outside core earnings, namely financial instruments valuations and cost of risk, presented offsetting developments in the first half of 2026, with an almost net-neutral impact in the income statement, compared to a net negative impact in the same period of 2025.

On the one hand, financial instruments valuation showed a positive contribution of €3.0 million in the income statement in the first half of 2026 (compared to -€10.2 million in the first half of 2025), primarily driven by AUD and USD appreciation versus EUR, partly offset by a tightening of the 3M EURIBOR-€STR basis.

On the other hand, cost of risk recorded a negative impact of €2.9 million in the first half of 2026, reflecting an increase in credit risk provisions, primarily due to higher probabilities of default and the origination of new operations, partly offset by the maturity of existing exposures. At end of June 2026, the CEB had not recorded any default or late payment of its counterparties.

General operating expenses, including depreciation and amortisation charges, increased by 6.0% reaching €34.3 million in the first half of 2026, compared to €32.4 million for the same period in 2025. This increase was mainly due to an increase in IT expenses. The adjusted cost-to-income ratio reached 32.7% at the end of June 2026, compared to 33.2% at the end of June 2025.

Balance sheet

The total balance sheet reached €43.0 billion as at 30 June 2026, an increase of 10.0% compared to €39.0 billion as at 31 December 2025. The increase primarily reflected the Bank’s usual intra-year funding cycle, with higher debt issuance early in the year resulting in a corresponding increase in liquid assets which winds down towards year-end.

The fair value of outstanding loans reached €23.3 billion as at 30 June 2026, increasing by 2.1% since 31 December 2025 (€22.8 billion).

Derivative valuation reflecting the positive fair value on the asset side reached €1.5 billion as at 30 June 2026, a decrease compared to €1.7 billion as at 31 December 2025. The negative fair value of derivatives recorded on the liability side amounted to €1.7 billion as at 30 June 2026, a decrease compared to €1.9 billion at the end of 2025.

Equity amounted to €4 921.4 million as at 30 June 2026 (31 December 2025: €4 874.2 million). The increase of €47.2 million (1.0%) since the end of 2025 is due to 2026’s net profit (€70.1 million), partially offset by the allocation of the 2025 net profit to the Social Impact Account (-€13.0 million) and the negative variation of gains or losses recognised directly in equity (-€9.9 million).

Key figures

As at 30 June 2026, the Bank’s new projects approved and loans disbursed amounted to €2.5 billion and €1.7 billion, respectively (30 June 2025: €2.7 billion and €1.1 billion, respectively). At the same date, the stock of approved projects awaiting financing amounted to €10.0 billion (31 December 2025: €9.4 billion), of which 56.3% were for CEB Target Group Countries in Central, Eastern and South-Eastern Europe (31 December 2025: 51.5%).

Outstanding nominal loans reached €24.0 billion as at 30 June 2026 (31 December 2025: €23.6 billion). Including accrued interest and value adjustments related to hedging, loans at fair value in the balance sheet amounted to €23.3 billion (31 December 2025: €22.8 billion).

The outstanding nominal amount of long-term bonds issued amounted to €33.8 billion as at 30 June 2026 (31 December 2025: €31.6 billion). During the first half of 2026, the Bank issued new bonds with a principal amount of €6.0 billion. Including accrued interest and valuation adjustments related to issued hedged bonds, the outstanding amount of these bonds, which support the Bank’s operations, amounted to €33.4 billion as at 30 June 2026, compared to €31.4 billion at the end of December 2025.

The outstanding nominal amount of short-term borrowings reached €2.0 billion as at 30 June 2026 (31 December 2025: nil), representing Euro Commercial Paper with maturities of less than one year issued since 1 January 2026.

All risk-appetite ratios remained within the approved limits throughout the period.

NOTES TO THE FINANCIAL STATEMENTS

NOTE A - Summary of accounting methods applied by the CEB

Accounting reference

The CEB’s separate accounts are prepared in accordance with IFRS as adopted by the European Union (EU).

The CEB’s separate condensed interim financial statements as at 30 June 2026 were prepared in compliance with IAS 34 Interim Financial Reporting and should be read together with the audited financial statements for the year ended 31 December 2025 (available on the Bank’s website www.coebank.org).

The reported half-year profits do not necessarily reflect the Bank’s full-year profits.

The half-year financial statements are unaudited.

Applicable accounting standards

The Bank did not implement the new accounting standards, amendments or interpretations adopted by the EU for which implementation was optional as at 30 June 2026.

NOTE B - CEB’s Risk Appetite Framework

As a multilateral development bank (MDB), the CEB is not subject to its member states' regulatory framework, the Basel Committee recommendations or EU directives for banking supervision. Nonetheless, the Bank's policy is to follow the best banking practices while making all necessary adjustments to reflect its MDB status. The CEB also refers to some indicators used by credit rating agencies. To this end, the CEB established a set of ratios and indicators in its Risk Appetite Framework to assess and monitor the risks arising from its activities.

The ratios and indicators are organised around five main areas: capital, leverage, liquidity, market risk and credit risk in finance activity.

^(*) Since 2024, the LCR ratio has been reported as an average of the last twelve end of month LCRs.    

Capital

Capital Adequacy Ratio is the Bank's Prudential Equity (E_p)¹ divided by total Risk-Weighted Assets (RWA). The Bank applies the Pillar I Standardised Approach, where RWA are calculated using risk-weight factors according to the counterparty type and the rating (the second-best rating among those indicated by external rating agencies).

The Bank monitors this ratio to ensure it holds sufficient capital to absorb unexpected losses arising from its various operations. The Risk Appetite Framework sets a minimum threshold of 10.5%. However, the Bank aims to keep the ratio above 20% to maintain strong financial fundamentals, with a comfort target above 25% to better align with the AAA criteria of leading credit rating agencies.

The Capital Adequacy Ratio reached 26.8% at the end of June 2026, down from 29.2% at the end of 2025 due to higher RWA arising from the cyclical activity at the beginning of the year related to the treasury and investment portfolios. Credit risk accounted for the bulk of capital consumption at 96.0% at the end of June 2026, split between credit risk in the loan portfolio (66.9%) and credit risk on finance operations (29.1%).

The Gearing Ratio measures the outstanding loans divided by “own-funds”², and thus establishes a volume ceiling to the Bank's loan activity. This ratio primarily provides a benchmark compared to other MDBs. The ceiling of the Risk Appetite Framework is 2.5.

With the ratio standing at 1.87 at the end of June 2026 (vs 1.85 at year-end 2025), the maximum permitted volume of outstanding loans was €32.0 billion (vs €31.8 billion at year-end 2025).

¹ Prudential Equity (Ep) includes paid-in capital, reserves, net profit and unrealised gains and losses.

² Subscribed capital, reserves and net profit. The calculation of this MDB-specific ratio excludes unrealised gains and losses on equity.

Leverage

The Leverage Ratio is calculated as Prudential Equity divided by the exposure value of all assets and off-balance sheet items. It provides a simple indicator (considering unweighted gross exposures) that complements the Capital Adequacy Ratio, acting as a limit to excessive leverage of the Bank. Both ratios use the same method for calculating derivative exposures (SA-CCR), and the same conversion factor of 50% for risk related off-balance sheet items (financing commitments). To ensure first-class financial fundamentals, the CEB’s Risk Appetite Framework sets its minimum threshold at 7%, compared with the 3% regulatory limit (EU CRR).

At the end of June 2026, the leverage ratio was 10.4% (11.2% at year-end 2025).

The Treasury Asset Ratio enables monitoring overall Treasury activity by comparing total financial assets (securities, deposits, nostro, adjusted for the fair value of hedging swaps) to prudential equity (E_p). The Risk Appetite Framework ceiling for this ratio is five times E_p, i.e. €23.4 billion at the end of June 2026 (€22.9 billion at the end of 2025).

This corresponds to a ratio of 3.70 at the end of June 2026, compared to 3.03 at year-end 2025. There is still sufficient leeway to accommodate both securities portfolios and deposits.

Liquidity

The Survival Horizon (SH) is the key metric for managing liquidity risk. It is the period during which the Bank is able to fulfil its payment obligations stemming from ongoing business operations under a severe stress scenario without any access to new funding and by selling its available liquid assets. The minimum Risk Appetite Framework level of this indicator is 12 months.

The SH indicator reached 21 months at the end of June 2026 (17 months at year-end 2025).

The Liquidity Coverage Ratio (LCR) measures the short-term resilience of the liquidity risk profile. It aims to ensure the Bank holds sufficient high-quality liquid assets (HQLA) to survive a period of significant liquidity stress lasting 30 calendar days.

The CEB’s LCR volatility is due to the cyclicality and scale of debt repayments (outflows) backed by interbank loan repayments (inflows) and to the effect of capping inflows at 75% of outflows. The 12-month average is therefore a more relevant indicator.

At the end of June 2026, LCR reached 728% (its 12-month average was 638%).

This comfortable level reflects the fact that the CEB does not collect deposits and has no access to central bank refinancing in emergency situations.

The Net Stable Funding Ratio (NSFR) measures the long-term resilience of the Bank’s liquidity risk profile. It requires the Bank to maintain a stable level of funding (available stable funding or ASF) relative to its activities (required stable funding or RSF), limiting short-term wholesale funding and maturity transformation risk.

The CEB's NSFR depends heavily on the outstanding debt issued (the Bank's main source of stable funding) and its residual maturity.

At the end of June 2026, the NSFR reached 142% (138% at the end of December 2025), showing a stable financing capacity.

Market Risk

The Sensitivity of the Economic Value of Equity (EVE) is the key metric to enable the Bank’s monitoring of interest rate risk. It measures the change in the net present value of the balance sheet, excluding equity, resulting from the most severe of the interest rate shocks defined by the Basel/EU regulations and the European Banking Authority (EBA). The limit is 20% of the CEB's prudential equity, in absolute terms.

At the end of June 2026, this indicator reached -14.6%, within the limit. The worst shock among the six proposed by the EBA would be a parallel shift upwards of 200 bp.

The spot Net Open Position (NOP) measures, per currency, the total assets minus liabilities in a foreign currency, including both on and off-balance sheet positions. The Risk Appetite Framework ceiling is, in absolute value, €1 million at month-end per currency. As in 2025, the limits were respected throughout the first half of 2026.

Credit Risk in Finance activity

The CEB sets minimum credit ratings for counterparties and issuers that must be met on the date of transactions carried out by the Bank (deposits and securities), depending on the maturity of the investment and the type of counterparty.

During the first half of 2026, all counterparties and transactions met the applicable minimum rating requirements on the respective transaction dates, as was the case in 2025.

NOTE C - Financial assets and liabilities

Financial assets and liabilities are presented in the table below according to their respective accounting valuation rules.
