Risk Drivers
What is pushing the current reading.
The current nuclear threat level is heightened by several factors: the potential resumption of U.S. nuclear testing marks a significant shift from decades of non-testing policy, which could trigger a new arms race and undermine global non-proliferation efforts. Additionally, the modernization of nuclear arsenals by major powers, such as the U.S. and China, coupled with deteriorating arms control agreements, exacerbates the risk of miscalculation and escalation. The geopolitical landscape is further strained by tensions in regions like the Middle East and the Korean Peninsula, where nuclear capabilities are a central concern. These developments, alongside reduced crisis communication channels, contribute to a precarious global nuclear stability environment.
