Ex-BoE deputy governor warns Trump could flick financial payments ’kill switch’

Former Bank of England official Jon Cunliffe highlighted growing concerns among U.S. allies regarding the potential weaponization of the U.S.-dominated global payments system and the dollar by a future Trump administration. This apprehension stems from heavy reliance on U.S. payment networks and banks, leading to fears of a 'kill switch' for financial transactions and a politicized Federal Reserve potentially withholding dollar liquidity during crises. Consequently, central banks like the BoE and ECB are already instructing lenders to assess their dollar funding needs under stress scenarios, signaling a proactive risk management approach to potential geopolitical financial disruptions.

Analysis

A former top Bank of England official, Jon Cunliffe, has highlighted significant and growing concern among U.S. allies over the potential for a future U.S. administration to weaponize the dollar-denominated global payments system for diplomatic leverage. The risk is centered on the heavy reliance of Western economies on U.S.-based networks like Visa and Mastercard, raising fears of a financial 'kill switch'. This concern is amplified by precedents such as the suspension of these services in Russia in 2022. The apprehension extends to monetary policy, with senior figures like BoE Governor Andrew Bailey and PIIE President Adam Posen voicing fears that a politicized U.S. Federal Reserve might restrict access to crucial dollar swap lines during a crisis. In a clear sign of proactive risk management, the BoE and ECB are reportedly already directing lenders to stress-test their U.S. dollar funding needs. While Cunliffe believes the U.S. would likely maintain liquidity to prevent global contagion, he warns of a severe scenario where these political risks converge with a loss of global confidence in the dollar, potentially triggering an emerging-market-style currency crisis.

Key Decisions for Investors

• Investors should re-evaluate geopolitical risk premiums across portfolios, particularly in assets highly dependent on the U.S. financial system, and consider hedging against potential dollar-centric financial disruptions tied to U.S. political outcomes.
• The concerns voiced by allied central banks may signal a long-term strategic shift to reduce reliance on U.S. payment systems; investors in Visa and Mastercard should monitor for the development of rival non-U.S. financial infrastructure which could represent a structural headwind.
• Fixed income and currency investors must closely monitor global U.S. dollar funding markets and central bank commentary for any signs of stress, as the perceived politicization of the Federal Reserve introduces new uncertainty regarding the availability of emergency dollar liquidity in a crisis.
