Given the way outstanding amounts of equity and debt are valued1 in national financial accounts2 , debt ratios calculated using these figures can give a distorted picture of the financial structure of non-financial companies. In contrast, capital increases and self-financing give a reliable approximation of changes in company capital. Our calculations suggest that French companies went into the pandemic in a strengthened financial position. Thus, the unprecedented increase in financial debt in 2020 (EUR 206 billion, with nearly EUR 130 billion in the form of government-guaranteed loans) was preceded, between 2015 and 2018, by a marked rise in capital, as the result of a significant increase in equity issues. However, these aggregate trends hide different pictures when individual companies, differing company sizes and different sectors are considered.
