Stress Testing Banks' Profitability: The Case of French Banks

We build a stress testing framework to evaluate the sensitivity of banks’ profitability to plausible but severe adverse macroeconomic shocks. Specifically, we test the resilience of French banks using supervisory data over the period 1993-2009. First, we identify the macroeconomic and financial variables (GDP growth, interest rate maturity spread, stock market’s volatility) and bank-specific variables (size, capital ratio, ratio of non interest income to assets) that significantly affect French banks’ profitability. Second, our macroeconomic stress testing exercises based on a simulation of macroeconomic variables show that French banks’ profitability is resilient to major adverse macroeconomic scenarios. Specifically, our findings highlight that even severe recessions would leave the French banking system profitable.

Stress Testing French Banks' Income Subcomponents

Using a broad dataset of individual consolidated data of French banks over the period 1993-2007, we seek to evaluate the sensitivity to adverse macroeconomic scenarios of the three main sources of banking income, namely interest margins, fees and commissions, and trading income. First, we show that the determinants of banking income subcomponents are highly specific: whereas interest rates spread plays a significant role in determining net interest income, stock market measures are significant determinants of trading income. GDP growth impacts significantly on fees and commissions. Second, our macroeconomic stress testing exercises tend to show that fees and commission and to a lesser extent trading incomes are much more sensitive to some adverse macroeconomic shocks than interest income. This could support the view that income diversification is associated with higher banking revenue resilience.

Macroeconomic Surprises and the Inflation Compensation Curve in the Euro Area

Using daily data stemming from inflation-indexed markets, we analyse the effects of numerous macroeconomic surprises on inflation compensation data - the sum of inflation expectations, risk and liquidity premia - in the euro area between 2 January 2004 and 31 December 2007. Our results suggest that when gauging short and medium-term inflation compensations, market operators are sensitive to surprises related to real activity and prices. Interestingly, oil futures prices tend to impact at some point on the short- and medium-ends of the inflation compensation curve. Notwithstanding, long-term inflation compensations remain generally unresponsive to macroeconomic surprises, attesting the high ECBs credibility.

Two-Way Interplays between Capital Buffers, Credit and Output: Evidence from French Banks

We assess the extent to which capital buffers (the capital banks hold in excess of the regulatory minimum) exacerbate rather than reduce the cyclical behavior of credit. We empirically study the relationships between output gap, capital buffers and loan growth with firm-level data for French banks over the period 1993—2009. Our findings reveal that bank capital buffers intensify the cyclical credit fluctuations arising from the output gap developments, all the more as better quality capital is considered. Moreover, by performing Granger causality tests at the bank level, we find evidence of a two-way causality between capital buffers and loan growth, pointing to mutually reinforcing mechanisms. Overall, those empirical results lend support to a countercyclical financial regulation that focuses on highest-quality capital and aims at smoothing loan growth.

Euro-Area Yield Curve Reaction to Monetary News

Abstract This paper compares the home-market performance of German multinational enterprises (MNEs) and national firms, both before and after switching from national to multinational activities. Regarding the former case, our results show that future multinationals outperform domestic firms. When assessing the ex post performance of multinationals, selectivity issues must be taken into account. Applying an endogenous treatment model, it turns out that after switching, both productivity and wage growth are higher at newly founded MNEs. While capital intensities increase compared with those of national firms, employment growth rates are negatively related to switching, suggesting that home and foreign employment are substitutes.

Determinants of the inflation compensation curve in the euro area

In this study, we analyse the effect of macroeconomic surprises on inflation compensation data – the sum of inflation expectation, risk and liquidity premia – in the euro area. The empirical analysis is based on a daily data set, which covers a wide spectrum of maturities, stemming from inflation-indexed markets between 2 January 2004 and 31 December 2007. Our results suggest that when gauging short- and medium-term inflation compensations, market operators are sensitive to surprises related to real activity and prices. Notwithstanding, long-term inflation compensations remain generally unresponsive to macroeconomic surprises, attesting the European Central Banks high credibility on the sample under consideration. The study also cross-checks the results from two different euro area inflation-indexed instruments (bonds and swaps) which differ slightly regarding medium-term horizon but give a similar picture regarding long-term horizons.

Structural Assessment of the Sacrifice Ratio and the Euro Area

In this paper, we seek to estimate the sacrifice ratio of the euro area using a small DSGE model where prices and wages are sticky. We estimate models parameters so as to minimize the distance between VAR-based and model-based covariances of a set of variables. The estimated value of the sacrifice ratio reaches 1.30%. In a second step, we proceed to a set of counterfactual exercises in order to highlight the link between the sacrifice ratio and the degree of prices and wages stickiness. We obtain that a decrease of prices stickiness does not necessary result in a decrease of the sacrifice ratio. In addition, the sacrifice ratio rises with the degree of wage stickiness.
