Economic crises don't announce themselves. Stablecoins represent exactly that kind of hidden vulnerability—a market mechanism we're still underestimating. Unlike traditional financial instruments, their sudden destabilization wouldn't just ripple through crypto markets; it could trigger cascading failures across connected systems. Think back to 2008: the velocity of collapse was the real killer. With stablecoins, the infrastructure is more interconnected but less transparent. One major depeg could be the spark that ignites a broader meltdown. We're sitting on a financial time bomb that most regulators haven't fully grasped yet.
