translate English to French: Yet, if the competition between the bank offer and the financial market has the effect of decreasing the costs of banking intermediation, banks benefit even so from it since, being intermediaries for the financial markets, they collect in return more commissions.
Or, si la concurrence entre le marché bancaire et le marché financier a pour effet de faire baisser les coûts d’intermédiation bancaire, les banques en tirent quand même avantage car elles collectent en contrepartie davantage de commissions.
