The Liberal Democrats have proposed the reintroduction of war bonds to help finance Britain's growing defence costs. Leader Ed Davey suggests that specially branded National Savings certificates could raise billions from a patriotic public, with funds ring-fenced for defence and industrial investment.
Under the plan, bonds would run for two to three years, paying the same interest as standard government bonds. The party argues this would stimulate growth and jobs, partially offsetting debt servicing costs. However, Treasury sources indicate little enthusiasm for reviving a policy last successfully administered over a century ago.
Critics note that war bonds are essentially more government debt, which must be repaid with interest. Historical precedents, such as financing the Napoleonic wars and both world wars, led to currency debasement and inflation. Modern investors might demand inflation-proofed or foreign-currency-denominated securities, complicating the scheme.
The success of war bonds depends on massive domestic uptake. During World War I, £3.3bn (about £20bn today) was raised, mostly from wealthy individuals and institutions. Today, if each of the UK's 28 million households lent £1,000 annually, it would raise £28bn—the estimated defence budget shortfall. However, this would not replace taxation, and increased borrowing would ultimately need repayment, assuming victory.
The question remains whether the British public is sufficiently wealthy and patriotic to sustain such an effort. Without widespread domestic support, foreign investors—who are not motivated by patriotism—may be reluctant to buy the bonds, especially if they doubt the UK's ability to maintain interest payments.
