The UK government has entered active negotiations to join a new international defence bank designed to provide low-cost financing for military and security projects across the West and its allies.
Chancellor John Healey is scheduled to meet the Canadian Finance Minister, François-Philippe Champagne, in London on Thursday, 17 September 2026, to discuss the terms of membership. The move signals the government’s approach to the Canada-led initiative.
The institution, officially known as the Defence, Security and Resilience Bank (DSRB), is modelled on the structure of the World Bank. It aims to offer long-term, low-interest loans to help allied nations rearm and modernise their security infrastructure.
Overcoming financing hurdles
A primary driver for the bank’s creation is the increasing difficulty defence firms face when attempting to secure capital from commercial lenders. Many private banks have become reluctant to fund the arms industry due to Environmental, Social, and Governance (ESG) criteria, which can classify defence spending as socially harmful or high-risk.
The DSRB intends to bypass these restrictions to provide long-term, low-cost financing for defence and security projects. For the UK, joining as a founding member would require an estimated upfront investment of £870 million, staggered over a three-year period.
Former Prime Minister Gordon Brown is understood to be assisting the Treasury as a global finance adviser during these negotiations.
Existing commitments
While the DSRB represents a significant new venture, the UK is already involved in similar international frameworks. In July 2026, the government launched the Multilateral Defence Mechanism (MDM) alongside the Netherlands, Finland, and Poland.
The Treasury is currently assessing how membership in the Canada-led DSRB will interact with its existing commitment to the MDM. Unlike the DSRB, which targets broad allied rearmament, the MDM has a more specific focus on regional security cooperation.
Diplomatic schedule changes
The talks between the Chancellor and his Canadian counterpart follow a disruption to the planned diplomatic schedule. Prime Minister Andy Burnham was forced to cancel a high-level meeting with Canadian Prime Minister Mark Carney on Wednesday due to a family bereavement following the death of his father.
Despite the cancellation of the leaders’ meeting, the technical and fiscal discussions regarding the DSRB are proceeding as planned. If the UK joins, it will sit alongside eight other founding nations, including Ukraine and Turkey, in a bid to bolster the collective industrial capacity of the NATO alliance.
No final decision on membership has been announced, but the Treasury is expected to weigh the upfront cost of £870 million against the long-term benefits of accessing low-cost credit for the UK’s own defence procurement targets.
