Britain floats joint plan with Europe to fund ‘large-scale rearmament’ throughout the continent as a part of ‘coalition of the keen’ amid rising fears of Russia battle

The UK could establish a ‘supranational institution’ with European nations to help finance a significant boost in defence spending across the continent.

Treasury officials have drawn up plans for a multilateral fund that would allow nations to borrow money for defence spending at favourable rates and purchase weapons for a common stockpile.

Backed by equity and sovereign guarantees from the coalition of countries involved, the new fund would both lend money for defence projects and enable the acquisition of military assets that could be used by any participating nation.

The paper, which was sent to European officials last week, suggests the fund could run up to ‘hundreds of billions of euros’, according to the Financial Times. 

European nations have been under intense pressure to increase their defence spending from the US amid growing fears of Russian aggression.

President Donald Trump has demanded nations on the continent spend at least five per cent of their GDP on defence, despite most countries aiming for two to three per cent.

If enacted, the proposed fund could help create a common stockpile of weapons that member states would only pay for when they use them.

Under the financing structure, governments would not be hit with upfront investment costs, meaning there will be less worry around financial capacity. 

Potential purchases noted in the paper include spare parts for tanks and aircraft, artillery shells, air defence munitions, explosives and logistics aircraft such as helicopters and carriers.

‘The institution would be designed to be classified to the rest of the world sector in the national accounts and the equipment purchased by the institution would be recorded on its own balance sheet and not the contributing countries,’ Treasury officials wrote.

‘This would avoid the upfront capital cost of purchasing equipment scoring to member countries’ budgets,’ the paper said, adding that it would be done in a way ‘consistent with sound fiscal management.

The fund could also lend to defence firms at favourable rates and to some governments at lower rates than they would be able to borrow on their own.

Some European officials have already cast doubt on the plan, however, with one saying: ‘My sense is that it isn’t very practical, because it could take a long time.’

Chancellor Rachel Reeves will join a meeting of EU finance ministers in Warsaw next week focused on defence financing.

The UK announced in February that they would hike defence spending to 2.5 per cent of GDP by slashing the foreign aid budget, while EU leaders agreed plans to jointly borrow €150billion to lend to individual governments for military expenditure. 

European Commission President Ursula von der Leyen said the announcement was part of a ‘Rearm Europe’ plan to unlock up to €800billion of additional defense spending over the coming years.

‘Europe is ready to massively boost its defense spending, both to respond to the short-term urgency to act and to support Ukraine, but also to address the long-term need to take on more responsibility for our own European security,’ she said last month.

Some of the measures proposed by the EU could prioritise procurement from defence companies on the continent, with American firms potentially phased out.

In recent days US officials have told their European counterparts that they want them to keep purchasing American-made arms.

A State Department spokesperson told Reuters that Trump welcomes recent efforts from European allies to ‘strengthen their defense capabilities and take responsibility for their own security,’ but warned against creating new barriers that exclude U.S. companies from European defense projects.

‘Transatlantic defense industrial cooperation makes the Alliance stronger,’ the spokesperson said.
