English to Italian Bus/Financial Finance (general)

come in:
Particularly for products with thin margins and a large back book, such as savings, pricing decisions on the front book will have a big impact on the entire portfolio’s profitability. For example, increasing interest rates to gain revenues from new deposits will simultaneously lower revenues on existing deposits. In contrast, when pricing for maximum margin, banks should determine the lowest interest rate that doesn’t motivate customers to withdraw savings. The price elasticity curve for products such as savings and mortgages is often complex and nonlinear. But when well understood and used, it can easily lift back-book revenue by 5 to 10 basis points for the portfolio.
