The United Kingdom has declined Canada’s invitation to join the international Defence, Security and Resilience Bank, but both countries have agreed to work closely together toward shared NATO spending goals.
Ottawa spent months trying to bring London into the DSRB, a multilateral institution designed to lower borrowing costs for military spending by combining the credit strength of allied nations. However, the UK chose instead to develop its own separate initiative, known as the Multilateral Defence Mechanism.

Two Banks, One Partnership
Despite the disagreement over membership, both governments reached an agreement on Sunday. They committed to building a cooperation framework between the two institutions. A joint media statement said both sides had “mutually concluded that it is best to develop two distinct but complementary institutions.”
The statement also confirmed that the DSRB and the UK’s Multilateral Defence Mechanism will “work in close partnership” on investment opportunities and shared challenges. In effect, the two banks will operate separately but coordinate their efforts where interests align.
DSRB Gains Support from Multiple Allies
Canada will host the DSRB. The bank already has the backing of several countries, including Belgium, Turkey and Ukraine. Meanwhile, eight nations have committed to the project overall, signaling growing international interest in pooled defence financing.
The UK’s decision not to join does not appear to have damaged broader bilateral relations. Both governments emphasized their shared commitment to meeting NATO spending targets. London’s preference for its own mechanism reflects a desire to maintain greater control over its defence financing structure, rather than any opposition to the DSRB’s goals.
The agreement to establish a cooperation framework between the Defence, Security and Resilience Bank and the UK’s parallel institution marks a practical compromise. It allows both countries to pursue their preferred approaches while still coordinating on defence investment at the international level. Further details on the framework are expected as both institutions continue to develop their structures and membership bases.
