Risk Drivers
What is pushing the current reading.
Recent developments indicate a concerning trend in nuclear proliferation and geopolitical tensions. China's expansion of its nuclear arsenal and alleged secret tests, coupled with ongoing disputes over Iran's nuclear program, highlight a destabilizing shift in global nuclear dynamics. The expiration of the last remaining nuclear arms control treaties exacerbates these risks, as it removes critical frameworks for managing nuclear competition and crisis communication. These factors converge to create a high-risk environment reminiscent of Cold War-era tensions, but with the added complexity of modern technologies and multi-polar power dynamics.
