  - To analyze the performance of French banks and the financial support measures taken by the French government.

### Importance of the French financial system
- France accounts for ten percent of the global banking system.
- France accounts for five percent of the global capital markets.
- France hosts the second largest mutual fund industry.

### II. BANKING AND SUPERVISORY STRUCTURE — Key features
- System composition:
  - Small number of large universal banks spanning a wide range of business functions.
  - Organized along commercial, mutual, and cooperative lines.
  - Private commercial banks: asset value about five times that of mutual and cooperative banks.
- Institutional linkages:
  - Close ties among banks, life insurance companies, and asset management companies (sometimes via cross-shareholding) blur divisions among institution types.
- International integration and market structure:
  - Home banks’ external claims well exceed host banks’ external claims.
  - Foreign banks have made few inroads into French mainstream retail banking, except for HSBC; strong presence in wholesale banking and securities trading.
  - Nine largest banks account for 75 percent of total banking assets.
  - Top five banks represent half of total deposits and more than a half of total lending.
  - Banking concentration stabilized over the last three years, but expected to rise with the merger between Groupe Caisse d’Épargne (GCE) and Groupe Banque Populaire (GBP) this year.
- Supervisory framework:
  - Functional approach with some twin peaks elements; financial oversight reformed in 2003 and substantially simplified.
  - Monetary and Financial Code does not distinguish commercial banks and investment banks.
  - Prudential supervision of banks and investment firms falls under the Commission Bancaire (CB).
  - Governor of the Banque de France (BdF) serves as chairman of the CB; BdF provides budget, human resources, and other support to the CB.
  - Board of financial sector authorities provides domestic coordination framework.

### III. INTERNATIONAL COMPARATIVE ANALYSES — Methodology and indicators
- Comparison group: 48 large banks in advanced Europe; only banks adopting IFRS included.
- Data sources: Bankscope and Thomson Financial; composite indicators weighted by size constructed for comparison group and nine major French banks.
- Select soundness indicators:
  - Profitability: operating ROAA and ROAE.
  - Asset quality: non-performing loans (NPL) ratio and coverage ratio.
  - Capital adequacy: Tier I ratio.
  - Leverage: assets over shareholders’ equity.
  - Capital quality: share of Tier II capital in total capital and core Tier 1 ratio.
  - Funding profile: share of wholesale funding in total funding and share of short-term wholesale funding in short-term funding.
  - Liquidity: deposit-to-loan ratio and liquid ratio (liquid assets over liquid liabilities).

### III.A Profitability — findings
- 2006: French banks’ operating ROAA and ROAE below peers due to narrower interest margins and less exposure to profitable, risky non-traditional activities.
- Net interest margin erosion from intense competition.
- 2008: both French and peer banks registered plummeting operating performance and net income.
  - Profitability of European banks turned negative in 2008, while French banks overall remained slightly positive because the majority still earned modest profits in 2008.

### III.B Asset quality — findings
- NPL ratio:
  - Declined in 2007 for both French banks and peers, reversed in 2008 reflecting economic/credit cycle turn and rising defaults.
- Coverage ratio:
  - Dropped appreciably in 2008 for both groups, indicating less provisioning relative to problem loans.
  - French banks had less coverage initially but experienced less marked deterioration and ended up with a higher coverage ratio in 2007-08.

### III.C Capital adequacy — findings
- 2006: Tier I ratio of French banks about 100 basis points above peers.
- 2007–08: crisis eroded buffers for both French banks and peers.
- 2008: government recapitalization efforts shrank the French banks’ edge and led to convergence with peers.

### III.D Leverage — findings
- Leverage levels and evolution of French banks mirrored European peers.
- No signs of deleveraging from pre-crisis levels for both groups.
- CB’s 2008 annual report: banks continued to expand intermediation business, though at a slower pace; leverage stabilized; no aggressive reduction in outstanding loans or restriction of riskier loan distribution observed.

### III.E Quality of capital — findings
- Global debate emphasized higher quality capital (core Tier 1).
- French banks had higher capital quality initially, but lead eroded after global recapitalizations in 2008.
- Both French banks and peers increased the share of Tier II capital in 2008; the increase was somewhat smaller for French banks.
- Core Tier 1 ratio:
  - French banks about 15 basis points above peers in 2007; on par with peers after 2008 recapitalizations.
- Liability management operations undertaken by several European banks (including some French banks) to buy back lower Tier II capital.

### III.F Funding and Liquidity — findings and key statistics
- Wholesale funding reliance:
  - During 2006-08 average funding profile for French banks: wholesale funding represents 58 percent of total funding.
  - Short-term (ST) wholesale funding accounts for about 35 percent of ST funding for French banks; for European peers the comparable figures are 47 percent and 28 percent, respectively.
  - Role of money market funds and life insurance products in diversified bank funding despite high national savings ratio.
- ALM liquidity perspective:
  - Deposit-to-loan ratio:
    - Rose to 75 percent in 2007 for French banks, slid in 2008 but remained above European peers.
  - Liquid ratio:
    - Declined by half to reach a similar level as peers in 2008.
  - Potential improvement: generalization of Livret A and Livret Bleu at the beginning of 2009 may encourage banks to attract more deposits.

### IV. ANALYSES OF BUSINESS AND EXPOSURES — business lines and geography
- Business line contributions (2006–08):
  - Domestic business share climbed modestly to 46 percent (low risk, high saturation).
  - International banking contribution to operating income rose from 18 percent in 2006 to 27 percent in 2008.
  - Corporate and investment banking (CIB): contribution fell from 24 percent pre-crisis to 10 percent in 2008 due to impairment charges and fair value losses from RMBS, CDO, ABS, monoline and CDPC exposures.
  - Asset management and private banking (AM & PB): combined contribution fell back to pre-crisis level; asset management hit by outflows and performance issues.
- Foreign exposure:
  - Foreign claims on immediate borrower basis: 34 percent of bank assets and 128 percent of GDP at end-2008; ultimate risk basis slightly lower.
  - Exposure distribution: 86 percent of foreign claims to mature markets; exposure to U.S., Italy, U.K., and Germany accounts for more than half of mature market exposure.
  - Exposure to emerging markets: about 4 percent of bank assets and 14 percent of GDP at end-2008.
  - Exposure to offshore financial centers: even smaller than emerging market exposure.
- Emerging market regional distribution (end-2008):
  - Central and Eastern Europe (CEE): about 36 percent of total exposure to emerging markets.
  - Africa and the Middle East: 28 percent.
  - Asia and the Pacific: 24 percent.
  - Among CEE exposures, Czech Republic, Russia, and Poland account for half of total exposure to CEE.
- Losses, writedowns, and capitalization:
  - French banks’ total losses and write-downs account for about 3 percent of global losses and write-downs since the crisis onset.
    - Comparatives: U.S. 55 percent, U.K. 12 percent, Germany 9 percent, Switzerland 7 percent.
  - CB’s international comparison of direct cost for large international banks: direct cost for French banks about 18 percent of Tier 1 capital (lower than Germany about 33 percent, U.K. about 37 percent, U.S. about 86 percent, Switzerland about 87 percent).
  - Recapitalization: total capital raised by French banks accounts for about 4 percent of aggregate capital raised around the globe.
  - State capital injections represent about one-third of new capital and play an increasing role over time.
- Market perception (CDS spreads):
  - Senior CDS spreads of French banks rose from less than 10 basis points pre-crisis to more than 100 basis points recently.
  - Junior CDS spreads rose from less than 30 basis points pre-crisis to more than 150 basis points recently.
  - Throughout most of the crisis, both senior and junior CDS spreads of French banks were lower than peers (iTraxx Euro indices).
  - At the peak in March 2009:
    - Junior CDS spreads of French banks were 36 percent below iTraxx Euro Junior index; in June they were 24 percent lower.
    - Senior CDS spreads of French banks were 17 percent and 8 percent below iTraxx Euro Senior index in March and June 2009, respectively.
  - Interpretation: markets may put a premium on national champions.

### V. EVENT STUDY OF THE FRENCH BANKING SECTOR SUPPORT (October 10–14, 2008)
- Context and global measures:
  - Lehman bankruptcy intensified contagion; governments implemented recapitalization, guarantees, deposit insurance, asset swaps/purchases, direct lending, liquidity facilities.
- French support architecture:
  - Société de Prise de Participations de l’État (SPPE):
    - Fully state-owned; recapitalization (Tier 1 instruments); earmarked €40bn.
    - First tranche: €10.5bn of deeply subordinated debt securities injected into six banks, boosting Tier 1 ratios by about 50 bps.
    - Additional €3bn supported merger between GCE and GBP.
    - Introduced preference shares as new core Tier 1 instruments with characteristics: non-cumulative dividend, no voting rights, non-convertible, preferential but capped remuneration, limited dilution, loss-absorbing capacity.
  - Société de Financement de l’Économie Française (SFEF):
    - Owned by French state (34 percent) and seven leading French banks (66 percent); provides government-guaranteed refinancing.
    - Can issue up to €265bn of guaranteed term debt (maximum maturity five years); debt must be issued before the end of 2009.
    - SFEF bonds enjoyed ‘AAA’ rating; issuance second only to the U.S. and about one third denominated in U.S. dollars; represents 20 percent of global issuance of government guaranteed bonds.
  - Guarantees:
    - Government issued guarantees on Dexia’s obligations (maximum of €55bn) prior to SFEF creation.
- Event-study methodology:
  - Event window: October 10–14, 2008 (one day before and after October 13 announcement).
  - Objectives:
    - Gauge market impact on debt using senior and subordinated CDS spreads linked to maturity structure.
    - Gauge market impact on equity using CAPM.
    - Control for contemporaneous events by measuring relative (adjusted) impact.
    - Reverse-engineer Black-Scholes-Merton (BSM) to measure proportion of equity injection transferred to debt holders.
  - Debt-impact calculation steps:
    - Back out default probability from CDS: DP = 1 - RR - CDS/10000 (expression as presented in source).
    - Gross impact on debt: difference between present value of debt before and after the plan (formula presented in source).
    - Adjusted impact: subtract debt changes in Scor Group, a reinsurance firm not receiving government money but experiencing narrowing spreads (formula presented in source).
- Event-study results — debt:
  - Gross appreciation of debt value across banks: range from 21 percent to 38 percent.
  - Adjusted appreciation (controlling for contemporaneous events): positive effects remain at least 9 percent.
  - Subordinated debt benefit greater than senior debt:
    - On average, subordinated debt value increased 35 percent gross and 25 percent adjusted.
    - Senior debt increased 26 percent gross and 14 percent adjusted.
- Event-study results — equity:
  - Gross impact: equity values experienced modest increases of 2–7 percent.
  - Adjusted impact (CAPM abnormal returns): negative across the board, with equity value losses ranging from one to 23 percent.
  - Using estimated betas generally produced larger equity value reductions than assuming beta = 1.
  - Interpretation: differential impacts on debt and equity suggest possible transfer of equity injections to debt holders (Myers (1977) mechanism).
- BSM reverse engineering — transfer estimates:
  - Model: asset value follows geometric Brownian motion; equity as call option and debt as put option on assets.
  - Calibration: back out implied asset value and volatility from market equity and volatility; compute ex-ante market values after announcement.
  - Results for three largest French banks: proportion of transfer ranges from 13 to 56 percent.
  - Correlation: transfer correlates with bank credit risk (average of CDS spreads of senior and subordinated debt): the riskier the debt, the higher the share of capital injections into debt.
  - Policy implication: capital injections may benefit debt holders at expense of shareholders, arguing for the necessity of government injections.

### VI. CONCLUSIONS — assessment and policy implications
- Overall assessment:
  - French banks have demonstrated relative resilience to the global financial crisis to date.
  - The universal banking model with diversification across business lines, funding, and geography helped contain risk to manageable levels.
  - Comprehensive supervision, proactive regulation, and timely information sharing among authorities contributed to better initial conditions and relative withstanding of the crisis.
- Ongoing challenges and risks to earnings:
  - Subdued CIB activities.
  - Potential losses and writedowns from risky assets.
  - Still low interest margins.
  - Rising counterparty risk and cost of risk.
- Policy response:
  - Recapitalization and refinancing measures have stabilized the system by reducing risk and decreasing financing costs considerably.
  - Continued vigilance and enhanced risk management required.
  - International debate on capital adequacy is evolving; the impact of reduced comparative advantage in capital buffers for banks remains to be seen.

### V. EVENT STUDY OF THE FRENCH BANKING SECTOR SUPPORT (October 10–14, 2008)
- Context:
  - French government measures prior to deepening of crisis focused on efficiency, competitiveness, and reforms (Paris-Place Financière initiative, Loi de Modernisation de l’Économie (LME)); post-SG trading fraud measures strengthened internal controls.
  - Lehman bankruptcy intensified contagion; governments implemented large-scale interventions globally: recapitalization, guarantees, deposit insurance, asset swaps/purchases, direct lending, liquidity facilities.
- French support architecture:
  - Two agencies created:
    - Société de Prise de Participations de l’État (SPPE): fully state-owned; recapitalization (Tier 1 instruments); earmarked €40bn.
      - First tranche: €10.5bn of deeply subordinated debt securities injected into six banks, boosting Tier 1 ratios by about 50 bps.
      - Additional €3bn supported merger between GCE and GBP.
      - Preference shares introduced as new core Tier 1 instruments with characteristics: non-cumulative dividend, no voting rights, non-convertible, preferential but capped remuneration, limited dilution, loss-absorbing capacity.

      - Can issue up to €265bn of guaranteed term debt (maximum maturity five years); debt must be issued before the end of 2009.
      - SFEF bonds enjoyed ‘AAA’ rating; issuance second only to the U.S. and about one third denominated in U.S. dollars; represents 20 percent of global issuance of government guaranteed bonds.
      - SFEF issuance attractive due to pooling liquidity and absence of bank risk exposure for investors.
  - Guarantees: government issued guarantees on Dexia’s obligations (maximum of €55bn) prior to SFEF creation.
- Event-study methodology:
  - Event window: October 10–14, 2008 (one day before and after October 13 announcement).
  - Objectives:
    - Gauge market impact on debt using senior and subordinated CDS spreads linked to maturity structure.
    - Gauge market impact on equity using CAPM.
    - Control for contemporaneous events by measuring relative (adjusted) impact.
    - Reverse-engineer Black-Scholes-Merton (BSM) to measure proportion of equity injection transferred to debt holders.
  - Debt-impact calculation steps (following Veronesi & Zingles (2008)):
    - Back out default probability from CDS: DP = 1 - RR - CDS/10000 (expression as presented in source).
    - Gross impact on debt: difference between present value of debt before and after the plan (formula presented in source).
    - Adjusted impact: subtract debt changes in Scor Group, a reinsurance firm not receiving government money but experiencing narrowing spreads (formula presented in source).

  - Interpretation: differential impacts on debt and equity suggest possible transfer of equity injections to debt holders (Myers (1977) mechanism).
- BSM reverse engineering to estimate transfer from equity injections to debt:
  - Model setup: asset value follows geometric Brownian motion; equity as call option and debt as put option on assets (equations and variables specified in source).
  - Procedure: calibrate BSM to market data (equity, volatility), back out implied asset value and volatility, calculate ex-ante market value of bonds and equities after announcement, determine share of equity injection transferred to debt by value difference relative to capital injections.
  - Results for three largest French banks: proportion of transfer ranges from 13 to 56 percent.
  - Transfer correlates with bank credit risk (average of CDS spreads of senior and subordinated debt): the riskier the debt, the higher the share of capital injections into debt.
  - Policy implication drawn: capital injections may benefit debt holders at expense of shareholders, arguing for the necessity of government injections.

  - Comprehensive supervision, proactive regulation, and timely information sharing among authorities contributed to better initial conditions and relative withstanding of the crisis.
- Ongoing challenges:

    - Subdued CIB activities.
    - Potential losses and writedowns from risky assets.
    - Still low interest margins.
    - Rising counterparty risk and cost of risk.
  - The global crisis remains unfolding and international debate on capital adequacy is evolving; the impact of reduced comparative advantage in capital buffers for banks remains to be seen.
  - Response required: continued vigilance and enhanced risk management.
