EU regulators are pushing for stricter capital rules on insurers' crypto holdings to address concerns over volatility and financial stability.The European Insurance and Occupational Pensions Authority (EIOPA) has proposed several options for regulating insurers' exposure to cryptocurrencies.The most aggressive approach would require insurers to assume crypto investments could lose their entire value, resulting in a 100% capital charge.EIOPA argues that historical data showing significant losses in major cryptocurrencies justifies the need for these stricter rules.
