UBS has come under fire for being the only Swiss financial institution among the top 30 investors in nuclear weapons manufacturers, having invested nearly $2.5 billion. Despite a decline in financing from other institutions, UBS continues to support this sector, raising concerns amid ongoing calls for disarmament. The International Campaign to Abolish Nuclear Weapons highlights the growing value of holdings in these manufacturers, now at $513 billion, while Switzerland has yet to join the Nuclear Weapons Ban Treaty.
