Risk Drivers
What is pushing the current reading.
The current nuclear threat level is elevated due to several concerning developments: the potential resumption of U.S. nuclear testing after decades, which could trigger a new arms race and undermine global non-proliferation efforts; Russia's announcement of new nuclear weapons, which adds to the strategic instability; and the ongoing modernization of nuclear arsenals by major powers. Additionally, geopolitical tensions are rising, with North Korea's expanding nuclear capabilities and Iran's potential nuclear ambitions, further complicating the global security landscape. The breakdown of key arms control treaties and reduced communication channels between nuclear states exacerbate these risks, making the situation more precarious than in recent years.
