French banks face a major test in their earnings reports: US$60 billion in sovereign debt exposure under scrutiny, with political turmoil and government bond volatility weighing on valuations?

French banks will face closer scrutiny when they report third-quarter results this week, as domestic turmoil puts investors' focus on their sovereign debt holdings and the risks from a potential economic slowdown. Data shows that BNP Paribas, Societe Generale and Credit Agricole together hold about US$60 billion of French sovereign debt. Most analysts believe the direct risk from this exposure is limited, but rising yields, political instability and social unrest could hit their home market economy, and at least one major retailer has already cut its guidance. France has gone through months of political wrangling over how to deal with a surge in public debt, which escalated into violent riots, six months before the presidential election. Business activity unexpectedly contracted in October, and the French bond market suffered historic turmoil last week, with the France-Germany bond spread rising to its highest level since 2011, when the eurozone debt crisis was at its peak. UBS Group analysts including Jason Napier said in a report: "The potential period of political uncertainty is too long, and there are too many alternatives among European banks that benefit from higher interest rates," so third-quarter results are unlikely to provide much incentive to buy French bank stocks. Analysts surveyed by the market expect BNP Paribas to report 3.5% growth in third-quarter profit when it announces results on October 28; Societe Generale will report the next day, and Credit Agricole on October 30, with both expected to post 9% growth in net profit. Data shows the three banks together hold about EUR54 billion (US$60.5 billion) of French sovereign debt. Including bonds held by insurance businesses, the scale rises to about EUR104 billion, but most of the additional risk is borne by policyholders rather than the companies themselves. Emmanuelle Assouan, head of the French Prudential Supervision and Resolution Authority (ACPR), said that unlike banks in Italy or Spain, which were at the center of the European sovereign debt crisis, French banks hold significantly less of their own country's debt, with international investors holding more than half, so there is no stability risk even if government bond yields soar. But that does not mean bond volatility has no impact. Banks classify bond holdings according to whether they plan to hold them to maturity or may sell them (for example, to manage liquidity or fulfill market-maker functions). Bonds available for sale or held for trading are usually marked to market, and large price swings during the reporting period can affect profit or regulatory capital. Veteran industry analyst Philip Richards said that even as fiscal and political pressure worsens and the France-Germany bond spread sits at a 15-year high of about 155 basis points, concerns about direct domestic sovereign debt risk at France's largest banks appear overdone, because amortized cost accounting and potential hedging provide protection. At the end of the second quarter, the Common Equity Tier 1 (CET1) ratios of BNP Paribas, Societe Generale and Credit Agricole were 13.0%, 13.2% and 11.3%, respectively, all comfortably above regulatory minimum requirements. Political turmoil and rising borrowing costs may also affect French banks in less direct ways, including a decline in loan demand as companies postpone investment. In addition, the cloud hanging over France is more broadly deterring investors and weighing on share prices across sectors. Supermarket operator Carrefour fell sharply last week after warning that protests and looting would weigh on this year's earnings. Deutsche Bank Chief Executive Christian Sewing said last week that France's fiscal and political instability is worrying and that volatility may persist until the presidential election. Recent polls show the vote could go to a second round, with far-right frontrunner Marine Le Pen facing far-left rival Jean-Luc Melenchon. "I wouldn't call it a debt crisis at the moment, but I think it is a wake-up call, especially for all public financing, where budget discipline is key," Sewing said in an interview. Investors in French banks will also focus on third-quarter trading performance after many U.S. rivals reported another jump in equity trading revenue while fixed-income trading declined. BNP Paribas Chief Executive Jean-Laurent Bonnafe may reveal more clues about future strategy, which he plans to announce early next year. "We clearly see a path to a cost-income ratio of around 50%," he said on an earnings call earlier this year. Since the end of June, shares of the three French banks have been among the worst performers among European banks. Valuations of French insurers, including AXA, have also been hit in recent weeks by investor concerns about the domestic situation. Jefferies analysts Philip Kett and Derald Goh said in a report that as of the end of June, AXA's exposure to French government bonds was EUR18 billion, accounting for 11% of its total government bond exposure. The insurer is seen as more affected by the wave of protests in France, which caused multiple incidents of property damage, with recent wildfires also adding to the impact.
