Our chart this week is based on the latter, with SIPRI reporting that global military expenditure has increased to $2,443bn in 2023, a 6.8% increase after adjusting for currency movements. SIPRI’s numbers are based on publicly available information, which means that some countries may be spending even more on their militaries that are included in the database. SIPRI was unable to obtain numbers for military spending by Cuba, North Korea, Syria, Yemen, Turkmenistan, Uzbekistan, Somalia, Eritrea, Djibouti, and Laos.

Military spending is the news this week following the announcement by the UK government that it will commit to spending 2.5% of GDP on defence and security, the recent vote by the US Congress to provide $95bn in military aid to Ukraine ($61bn), Israel ($26bn) and Taiwan and others in the Indo-Pacific ($8bn), and the release of the Stockholm International Peace Research Institute (SIPRI) Military Expenditure Database for 2023.

More than half of that spending is incurred by NATO, with total military spending of $1,351bn, comprising $916bn by the US, $75bn by the UK and $360bn by other NATO members. Of the latter, $307bn was spent by the 23 members of the EU that are also members of NATO (including $67bn by Germany, $61bn by France, $36bn by Italy, $32bn by Poland and $24bn by Spain), while $53bn was spent by the other seven members (including $27bn by Canada and $16bn by Türkiye).

The Shanghai Cooperation Organisation (SCO) and the Collective Security Treaty Organisation (CSTO) are partially overlapping economic and military alliances convened by China and Russia respectively. China has the biggest military with $296bn spent in 2023, while Russia spent $109bn and other members spent $106bn (of which India spent $84bn).

We have categorised the rest of the world between other US allies which spent $304bn in 2023 (including $76bn by Saudi Arabia, $50bn by non-US members of the Rio Pact, $50bn by Japan, $48bn by South Korea, $32bn by Australia, $27bn by Israel and $17bn by Taiwan), Ukraine which spent $65bn, and $212bn spent by other countries for which SIPRI has data.

The numbers do not take account of the differences in purchasing power, particularly on salaries. That means China and India, for example, can employ many more soldiers, sailors and aircrew than NATO countries can for the same amount of money.

The Ukraine number also excludes $35bn in military spending funded by the US ($25bn) and other partners ($10bn) during 2023 that was not part of its national budget.

Global military spending is expected to increase further in 2024 as the international security situation deteriorates. This includes NATO members that plan to increase their defence and security spending to meet or exceed the 2% of GDP NATO minimum guideline set in 2014 to be achieved by 2024.

This includes the UK, which now plans to increase its spending on defence and security from 2.35% of GDP in 2023/24 to 2.5% of GDP by 2028/29, with suggestions from defence sources that setting a target of 3% of GDP may be necessary at some point in the next decade.

ICAEW chart of the week: global military spending

19 March 2021: The UK’s Integrated Review is the inspiration for this week’s chart, illustrating the 20 countries around the world that spend the most on their militaries.

Chart showing global military spending in 2019 led by USA (£526bn) and China (£200bn) followed by 18 other countries - see text below the chart for details.

The UK Government launched its Integrated Review of Security, Defence, Development and Foreign Policy on 16 March 2021, setting out a vision for the UK’s place in the world following its departure from the European Union and in the context of increasing international tensions and emerging security threats.

At the core of the Integrated Review is security and defence, and ICAEW’s chart of the week illustrates one aspect of that by looking at military spending around the world. 

The chart shows spending by the top 20 countries, which together comprise in the order of £1.2tn of estimated total military spending of around £1.4tn to £1.5tn globally in 2019 – an almost textbook example of the 80:20 rule in action.

More than a third of the total spend is incurred by just one country – the USA – which spent in the order of £526bn in 2019 converted at current exchange rates. The next biggest were China and India at £200bn and £50bn respectively, although differences in purchasing power mean that they can afford many more soldiers, sailors and aircrew for the same amount of money. This is followed by Saudi Arabia (£45bn), Russia (£41bn), France (£38bn), the UK (£38bn), Germany (£38bn), Japan (£34bn), South Korea (£33bn), Australia (£21bn), Italy (£20bn), Canada (£17bn), Israel (£16bn), Brazil (£14bn), Spain (£13bn), Turkey (£11bn), the Netherlands (£9bn), Iran (£9bn) and Poland (£9bn).

Exchange rates affect the relative orders of many countries in the list, for example between Russia, France, the UK and Germany which can move up or down according to movements in their currencies, while there are a number of caveats over the estimates used given the different structures of armed forces around the world and a lack of transparency in what is included or excluded in defence budgets in many cases.

In addition, the use of in-year military spending does not necessarily translate directly into military strength. Military capabilities built up over many years or in some cases (such as the UK) over many centuries need to be taken into account, as do differing levels of technological development and spending on intelligence services, counter-terrorism and other aspects of security. Despite these various caveats, estimated military spending still provides a useful proxy in understanding the global security landscape and in particular highlights the UK’s position as a major second-tier military power – in the top 10 countries around the world.

Global Britain in a Competitive Age: the Integrated Review of Security, Defence, Development and Foreign Policy sets out some ambitious objectives for security and defence, which it summarises as follows: “Our diplomatic service, armed forces and security and intelligence agencies will be the most innovative and effective for their size in the world, able to keep our citizens safe at home and support our allies and partners globally. They will be characterised by agility, speed of action and digital integration – with a greater emphasis on engaging, training and assisting others. We will remain a nuclear-armed power with global reach and integrated military capabilities across all five operational domains. We will have a dynamic space programme and will be one of the world’s leading democratic cyber powers. Our diplomacy will be underwritten by the credibility of our deterrent and our ability to project power.”

The estimates of military spending used in the chart were taken from the Stockholm International Peace Research Institute (SIPRI)’s Military Expenditure Database, updated to current exchange rates.
