### I. Introduction and context
- Italian 10-year government bond spreads:
  - Remained below 200 basis points (bps) until June 2011.
  - Climbed, peaking at over 500 bps at end-2011.
  - Tightened in spring 2012 after the 3-year Long Term Refinancing Operations (LTRO).
  - Widened again reaching more than 500 bps in July 2012.
  - Came down steadily since the announcement of the details of the Outright Monetary Transactions (OMT) program in September 2012.
- Bank funding and lending conditions:
  - Banks’ CDS spreads and bond yields exceeded those of other European peers in summer 2011.
  - 12-month credit growth to the non-financial private sector dropped from 3.5 percent in November 2011 to -0.9 percent in December 2012.
- Paper objectives:
  - Examine determinants of Italian sovereign spreads movements: role of investor risk appetite, fiscal developments, and news (international and Italian specific).
  - Assess pass-through of sovereign spreads to Italian banks’ CDS, bond yields, lending rates and credit growth.

### II. Key empirical findings on sovereign spreads drivers
- Main drivers identified:
  - Investor risk appetite proxied by the VIX index (implied volatility of S&P options) has a statistically significant impact on Italian sovereign spreads.
  - News related to the euro area debt crisis and Italy-specific events have sizable impacts on daily changes in 10-year spreads.
  - Projected public debt to GDP ratio and the share of public debt securities held by non-residents amplify the effect of risk appetite shocks on spreads.
- Specific quantitative relationships and observations:
  - From end June 2011 to end December 2011, 10-year bond spreads rose from 186 bps to 527 bps.
  - The monthly standard deviation of spreads peaked in December 2011–January 2012.
  - Interaction effects:
    - Changes in the VIX interacted with the projected debt to GDP ratio push up spreads.
    - The VIX interaction with the share of public debt held by non-residents significantly increases spread sensitivity to risk appetite shocks.
  - Example from text:
    - At the debt to GDP ratio projected for 2012, a one standard deviation shock in the VIX index sustained for 5 days (a 10 percentage point increase) would increase spreads by almost 24 bps.
- Event-driven volatility:
  - Largest daily changes in spreads occurred at the time of international and Italian-related announcements and events.
  - Both international bad/good news and Italy-specific bad/good news have statistically significant and large impacts on daily changes in spreads (regressions over January 1, 2008–October 22, 2012).

### III. Co-movements among banks’ CDS and common factor
- Principal component evidence:
  - Almost 70 percent of the variance in the euro area banks’ CDS and sovereign spreads series is explained by the first principal component.
  - Loadings on the first principal component are all positive and similar in size, suggesting a latent common risk indicator.
- Channels linking sovereign spreads and banks’ risk:
  - Financial-sector weakness driving sovereign spreads where governments committed large public resources.
  - Shocks to sovereign bond yields affecting banks via rating caps, funding costs, profitability, and portfolio values.
  - Risk repricing and changes in investor risk appetite transmitting shocks across bank and sovereign risk premiums.

### IV. Impact of sovereign spreads on banks’ market indicators
- Correlation and tracking:
  - Average CDS spreads of the five largest Italian banks tracked the iTraxx Europe senior financial index and average CDS of largest euro area banks, but exceeded peers in summer 2011 during sovereign stress.
  - Correlation between changes in banks’ CDS spreads and changes in the 10-year Italian government bond spread over the Bund increased from less than 0.1 (January 2006–June 2007) to 0.6 (July 2001–October [text cuts off]).
- Econometric (CDS differential) findings (sample January 1, 2007- July 31, 2012):
  - Changes in sovereign spreads significantly impact the CDS spreads differential of the five largest Italian banks versus a group of euro area banks.
  - Interaction sovereign spreads × bank capital: positive and significant — impact larger for institutions with relatively lower capital.
  - Interaction sovereign spreads × relative NPL ratio: positive and significant — impact larger for banks with higher non-performing loans.
  - VIX index: statistically significant effect on dynamics of four banks’ CDS.
  - Libor-OIS spread: tensions in interbank market do not appear to have increased Italian banks’ CDS spreads relative to other euro area banks.

### V. Impact on banks’ bond yields
- Econometric (bond yield differential) findings (period January 1, 2007- July 31, 2012):
  - Changes in sovereign spreads significantly impact the bond yield differential of the five largest Italian banks vis-à-vis a group of euro area banks.
  - Interaction effects:
    - Sovereign spread × bank capital: positive and significant for four of the Italian banks.
    - Sovereign spread × relative NPL ratio: positive and significant.
    - Interpretation: banks with lower relative capital ratios and higher non-performing loans were more sensitive to changes in sovereign spreads.
  - Quantified effect:
    - A 100 bps widening in Italian sovereign spreads would result in an average 15-20 bps increase in Italian banks’ bond yields compared to other euro area banks.
  - VIX index: positive sign; statistically significant consistently only for two banks.
  - Libor-OIS spread: mixed evidence on statistical significance for bond yields.

### VI. Transmission to lending conditions and credit volumes
- Lending rates and sovereign spreads:
  - Rates on new firm loans increased by 100 bps in the second part of 2011.
  - Rates on new mortgages rose by 80 bps in the same period.
  - From January (unnamed year in source), rates on firm loans started to decline as sovereign spreads fell.
  - Movements in Italian bank securities’ yields have been more correlated with sovereign spreads than with the 3-month euribor.
- VAR (monthly, January 2006-September 2012) pass-through results:
  - Endogenous variables: lending rate, 10-year government bond spread over the Bund, average CDS spreads of the five largest Italian banks (all in first differences).
  - Exogenous variable: changes in the 3-months euribor.
  - Pass-through:
    - About 30-40 percent of the increase in sovereign spreads is transmitted to firm lending rates within three months.
    - 50-60 percent is transmitted within six months.
    - Pass-through is somewhat higher for small loans.
  - Supporting estimate from literature:
    - Albertazzi et al. (2012): a temporary 100 bps increase in 10-year government bond spreads is associated with about 50 bps increase in firm loan rates after a quarter; permanent increases fully transmitted after one year.
- Credit volumes and composition:
  - 12-month credit growth to the non-financial private sector dropped from 3.5 percent in November 2011 to -0.9 percent in December 2012.
  - 12-month growth in loans to small firms declined from 0.4 percent year-on-year in November 2011 to -5.9 per cent in November 2012.
  - Bank and business surveys at end-2011 point to tight lending standards similar to the period after the Lehman bankruptcy.
- Supply vs. demand (quarterly, 2003Q2-2012Q3):
  - At end-2011, supply constraints driven by bank funding difficulties prevailed over weak demand:
    - Estimates of excess demand suggest growth in loan demand exceeded credit supply by 0.5 percentage points in 2011Q4.
    - Net corporate bond issuance returned positive in 2011Q4 after being negative for several months, suggesting substitution from bank borrowing to bond issuance.
  - In 2012, weak demand drove changes in credit more than supply.
  - After LTROs and other policy actions, estimated demand for credit fell well short of supply.
- Historical perspective:
  - Four quarters since the start of the recession, nominal annual credit growth to the private sector declined by 5.4 percentage points, compared to declines of 13.2 and 11.0 percentage points respectively during corresponding periods in the early 1990s and 2008–09.

### VII. Main conclusions
- Volatility in the Italian sovereign debt market intensified since the summer of 2011, pushing up Italian banks’ funding costs and tightening lending conditions.
- Shocks in investor risk appetite, euro area debt crisis news, and Italy-specific news have been important drivers of Italian sovereign spreads.
- Italy’s high public debt and the large share of non-resident holdings of government debt amplified the impact of investor risk appetite shocks on spreads.
- Italian banks’ CDS spreads exceeded those of euro area peers since summer 2011; sovereign spreads significantly contributed to widening this differential.
- Banks with lower relative capital ratios and higher non-performing loans are more sensitive to changes in sovereign spreads.
- Increases in sovereign spreads rapidly drive up firm lending rates (about 30-40 percent of the shock transmitted within a quarter).
- Credit growth to Italian firms declined significantly, reflecting both weak demand and supply constraints; supply constraints prevailed at end-2011, while weak demand dominated in 2012.

### VIII. Policy implications and recommendations
- Reduce vulnerabilities to contain sovereign risks:
  - Need to reduce country-specific vulnerabilities (e.g., high debt levels).
  - Need to reduce euro area vulnerabilities.
- Financial stability considerations:
  - Large share of non-resident holdings of government debt increases sensitivity of spreads to global risk appetite shocks—implying benefits from measures that enhance investor base stability and reduce rollover/funding risks.
  - Strengthening bank balance sheets (capital ratios, asset quality) can mitigate the amplification of sovereign stress into bank funding costs and lending conditions.
- Broader priorities:
  - Continued efforts to strengthen banks’ capital buffers and reduce impaired assets, given banks with lower capital and higher NPLs are more sensitive to sovereign shocks.

### 2012. Co-movements among banks’ CDS

### 2012. Co-movements among banks’ CDS

### Co-movements and common factor
- Peaks in banks’ CDS and sovereign spreads have coincided with major international events, such as the Lehman Brothers’ bankruptcy, and the announcement of the Greek program.
- A principal component analysis indicates that almost 70 percent of the variance in the euro area banks’ CDS and sovereign spreads series is explained by the first principal component.
- The loadings on the first principal component are all positive and similar in size, suggesting a latent common risk indicator driving movements across series.

### Channels linking sovereign spreads and banks’ risk
- Three possible channels for correlation:
  - Financial-sector weakness driving sovereign spreads, especially where governments committed large public resources to support financial institutions.
  - Shocks to sovereign bond yields impacting banks’ risk profile via:
    - Rating agencies capping bank ratings on the basis of sovereign rating.
    - Government bond yields affecting banks’ funding costs, profitability, and the value of government securities in banks’ portfolios.
    - A sovereign with heightened risk having limited room to support the banking system if needed.
  - Risk repricing and changes in investor risk appetite transmitting shocks across both bank and sovereign risk premiums.

### Econometric analysis — CDS spreads differential
- Sample and dependent variable:
  - Daily observations covering the period January 1, 2007- July 31, 2012.
  - Dependent variable: change in the differential between 5-year CDS spreads of each of the five largest Italian banks and the average CDS spreads of a group of euro area banks.
- Explanatory variables included:
  - Lagged dependent variable.
  - 5-year Italian sovereign CDS spreads or 10-year government bond spreads over the Bund (lagged).
  - Bid-ask spreads of each bank’s CDS premium (indicator of CDS liquidity; bid-ask spread is stationary).
  - VIX index (proxy for general risk aversion).
  - Euro 3-month Libor-OIS spread (measure of counterparty risk in the interbank market).
- Estimation method:
  - Seemingly unrelated regression to account for error term correlation among the five Italian banks.
  - All variables are differenced except the bid-ask spread.
- Key econometric findings:
  - Changes in sovereign spreads have had a significant impact on the CDS spreads differential of the five largest Italian banks with respect to a group of euro area banks.
  - Interaction between sovereign spreads and bank capital:
    - The interaction term between sovereign spreads and bank capital has a positive and significant coefficient.
    - Interpretation: the impact of sovereign risk on bank risk is larger for institutions with relatively lower capital levels.
  - Interaction between sovereign spreads and non-performing loans (NPLs):
    - The interaction term between sovereign spreads and the relative non-performing loan ratio has a positive and significant coefficient.
    - Interpretation: sovereign spreads shocks have a greater impact on CDS spreads of banks with higher non-performing loans.
  - VIX index:
    - Statistically significant effect on the dynamics of four banks’ CDS, indicating higher credit risk premiums on some Italian banks when risk appetite declines.
  - Libor-OIS spread:
    - Tensions in the interbank market, as measured by the Libor-OIS spreads, do not appear to have increased Italian banks’ CDS spreads relative to other euro area banks.

### Econometric analysis — bank bond yields
- Sample and dependent variable:
  - Period January 1, 2007- July 31, 2012.
  - Dependent variable: change in the differential between yields on bonds issued by Italian banks and the average yields on bonds issued by a group of euro area banks.
- Explanatory variables included:
  - Lagged dependent variable.
  - Changes in 5-year Italian sovereign CDS spreads or 10-year government bond spreads over the Bund (lagged).
  - Changes in the VIX index.
  - Changes in the euro 3-month Libor-OIS spread.
  - Interaction terms: lagged changes in sovereign spreads interacted with relative bank capital and relative NPL ratio.
- Estimation method:
  - Seemingly unrelated regression.
- Key econometric findings:
  - Changes in sovereign spreads have had a significant impact on the bond yield differential of the five largest Italian banks vis-à-vis a group of euro area banks.
  - Interaction effects:
    - Sovereign spread × bank capital: positive and significant coefficient for four of the Italian banks.
    - Sovereign spread × relative NPL ratio: positive and significant coefficient.
    - Interpretation: banks with lower relative capital ratios and higher non-performing loans were more sensitive to changes in sovereign spreads.
  - Quantified effect:
    - A 100 bps widening in Italian sovereign spreads would result in an average 15-20 bps increase in Italian banks’ bond yields compared to other euro area banks.
  - VIX index:
    - Positive sign; statistically significant consistently only for two banks.
  - Libor-OIS spread:
    - Mixed evidence on statistical significance for bond yields.

### Impact on lending conditions and credit volumes
- Lending rates and sovereign spreads:
  - Rates on new firm loans increased by 100 bps in the second part of 2011.
  - Rates on new mortgages rose by 80 bps in the same period.
  - From January (unnamed year in source), rates on firm loans started to decline as sovereign spreads fell.
  - Movements in Italian bank securities’ yields have been more correlated with sovereign spreads than with the 3-month euribor.
- VAR analysis (monthly, January 2006-September 2012):
  - Endogenous variables: lending rate, 10-year government bond spread over the Bund, average CDS spreads of the five largest Italian banks (all in first differences).
  - Exogenous variable: changes in the 3-months euribor.
  - Pass-through results:
    - About 30-40 percent of the increase in sovereign spreads is transmitted to firm lending rates within three months.
    - 50-60 percent is transmitted within six months.
    - Pass-through is somewhat higher for small loans.
  - Supporting literature:
    - Albertazzi et al. (2012): during the sovereign debt crisis, a temporary 100 bps increase in 10-year government bond spreads is associated with about 50 bps increase in firm loan rates after a quarter; permanent increases fully transmitted after one year.
- Credit volumes and composition:
  - 12-month credit growth to the non-financial private sector dropped from 3.5 percent in November 2011 to -0.9 percent in December 2012.
  - 12-month growth in loans to small firms declined from 0.4 percent year-on-year in November 2011 to -5.9 per cent in November 2012.
  - Evidence from bank and business surveys at end-2011 points to tight lending standards similar to the period after the Lehman bankruptcy.
- Supply vs. demand in credit growth (loan supply and demand functions, sample 2003Q2-2012Q3):
  - Model uses Bank Lending Survey indicators as proxies for unobserved demand and supply; estimated with instrumental variables.
  - At end-2011, supply constraints driven by bank funding difficulties prevailed over weak demand:
    - Estimates of excess demand suggest growth in loan demand exceeded credit supply by 0.5 percentage points in 2011Q4.
    - Net corporate bond issuance returned positive in 2011Q4 after being negative for several months, suggesting substitution from bank borrowing to bond issuance.
  - In 2012, the situation reversed: weak demand drove changes in credit more than supply.
  - After LTROs and other policy actions, estimated demand for credit fell well short of supply.
- Historical perspective:
  - 12-month corporate credit growth fell sharply in the recent episode but the pace of slowdown has been somewhat milder than in the 1992–93 recession.
  - Four quarters since the start of the recession, nominal annual credit growth to the private sector declined by 5.4 percentage points, compared to declines of 13.2 and 11.0 percentage points respectively during corresponding periods in the early 1990s and 2008–09.

### Conclusions and policy implications
- Main conclusions:
  - Volatility in the Italian sovereign debt market intensified since the summer of 2011, pushing up Italian banks’ funding costs and tightening lending conditions.
  - Shocks in investor risk appetite, euro area debt crisis news, and Italy-specific news have been important drivers of Italian sovereign spreads.
  - Italy’s high public debt and the large share of non-resident holdings of government debt amplified the impact of investor risk appetite shocks on spreads.
  - Italian banks’ CDS spreads exceeded those of euro area peers since summer 2011; sovereign spreads significantly contributed to widening this differential.
  - Banks with lower relative capital ratios and higher non-performing loans are more sensitive to changes in sovereign spreads.
  - Increases in sovereign spreads rapidly drive up firm lending rates (about 30-40 percent of the shock transmitted within a quarter).
  - Credit growth to Italian firms declined significantly, reflecting both weak demand and supply constraints; supply constraints prevailed at end-2011, while weak demand dominated in 2012.
- Policy implications highlighted in the source:
  - Importance of reducing country-specific vulnerabilities to contain sovereign risks.
  - Need to address fragilities in the euro area at large to contain Italy’s sovereign risks.
  - Broader benefits from continued efforts to strengthen banks’ capital buffers and reduce impaired assets, given banks with lower capital and higher NPLs are more sensitive to sovereign shocks.
