UK Considers Joining Canada-Led Global Defence Bank Initiative

Update: 16 September 2026, 6:17:55 AM

Chancellor John Healey is currently engaged in discussions with Canadian officials regarding the United Kingdom’s potential participation in a new international defence bank. This initiative aims to assist allies in rearming amid escalating global security threats, a move that comes shortly after previous resistance from the Treasury.

The proposed Canada-led Defence, Security and Resilience Bank (DSRB) seeks to secure roughly €100 billion to provide low-cost loans to governments and contractors for critical defence projects. It would additionally provide financial guarantees for lenders supporting smaller defence firms. While the UK has maintained a AA credit rating since 2016, proponents suggest the bank could offer a more efficient way to fund high-cost military ventures.

Healey, a long-term advocate for multilateral funding, met with Canadian finance minister François-Philippe Champagne twice during a G20 summit in North Carolina last month. The pair are scheduled to meet again in the UK this week, with further discussions expected during EU finance minister meetings in Dublin. Canada has reportedly extended a formal invitation for the UK to join as a founding member, alongside eight other nations, including Ukraine and Turkey.

The debate over joining the DSRB follows previous internal friction. When he served as defence secretary, Healey pushed for UK oversight of the bank’s development, despite efforts from the Treasury to limit involvement. His predecessor, Rachel Reeves, had expressed skepticism, citing concerns that the bank would not sufficiently address UK procurement issues. Furthermore, the UK has already committed to the Multilateral Defence Mechanism (MDM), a separate lender launched in July with partners including the Netherlands, Finland, and Poland.

Treasury concerns regarding the DSRB center on potential overlaps with existing initiatives and the significant capital commitments required during a period of fiscal constraint. Estimates suggest the UK would need to contribute between £1 billion and £2 billion over a three-year period.

Financial and Strategic Context

Initial MDM Commitment: £600 million.
Projected DSRB Capital Requirement: £1 billion to £2 billion over three years.
Procurement Goal: Utilizing the MDM to improve efficiency by up to 20%.
Defence Spending Strategy: Healey aims to outline a pathway toward a 3% spending target in the 2027 review rather than setting a specific date in the upcoming budget.

Healey, who resigned as defence secretary in June after citing a £13 billion gap in defence funding, remains focused on long-term security industrial capacity. The current government stance reflects a desire to balance these multiple commitments.

A government spokesperson confirmed the ongoing evaluation: “We are fully committed to working alongside our international partners to scale defence industrial capacity. We are working closely with our Canadian allies on ensuring the Multilateral Defence Mechanism and Defence Security Resilience Bank are complementary.” The report also notes that when the two men are – according to sources – likely to discuss the defence bank, and both are expected to be at EU finance minister talks in Dublin later this week, they are due to meet again in the UK this week. The report also notes that accusing Keir Starmer and his chancellor, Reeves, of putting the country’s security at risk because the defence spending package fell £13bn short of what he argued was required, healey resigned as defence secretary in June. The report also notes that separate from the balance sheets of already indebted nations, to boost defence investment, the DSRB could play a role in this by using financial leverage. The report also notes that but it would need additional sovereign backing beyond current commitments to become a major player. The report also notes that which would give taxpayers better value for money while allowing government to borrow at a low rate to fund defence, she said the MDM would help the UK with procurement – saving the UK as much as 20% – and stockpiling.
