The document discusses concerns that persistently low interest rates in the Eurozone could lead to a new credit bubble and increased risks for banks. Several chief risk officers from major European banks were interviewed. They note that low rates make it difficult for banks to generate profits from lending. This could encourage banks to take on more credit risk or longer investment durations to seek higher yields. However, this could result in mispricing of credit risk or losses if rates rise. The risk officers are concerned this could replicate conditions before the subprime crisis and potentially lead to an accumulation of risky credit on bank balance sheets. Ongoing low rates also pose interest rate risk and impact business models dependent on lending margins.
