Credit card regulation is back in focus after fresh policy proposals made waves in financial markets. $COF took a significant hit, dropping over 10%, as investors immediately priced in the implications of potential rate caps. The move reflects broader market sensitivity to shifts in monetary and fiscal policy—traders are reassessing exposure to financial services stocks that could face margin pressure under stricter lending regulations. This kind of sharp reaction underscores how macroeconomic signals can ripple across asset classes. For those tracking correlations between traditional finance headwinds and crypto markets, this is a textbook example of systemic risk contagion worth monitoring.
