STOCKHOLM (AP) – Global military spending grew for the eighth consecutive year in 2022 to an all-time high of $2.24 trillion, with a sharp rise in Europe, chiefly due to Russian and Ukrainian expenditure, a Swedish think tank said Monday.

Spending globally increased by 3.7 percent in real terms, but military expenditure in Europe was up 13 percent—its steepest year-on-year increase in at least 30 years, the Stockholm International Peace Research Institute, or SIPRI, said in a report. Military aid to Ukraine and concerns about a heightened threat from Russia “strongly influenced many other states’ spending decisions.”

The independent Swedish watchdog said that last year, the three largest arms spenders were the United States, China and Russia, who between them accounted for 56 percent of global expenditure.

The rise “is a sign that we are living in an increasingly insecure world,” said Nan Tian, a researcher with SIPRI’s Military Expenditure and Arms Production Program.

Several states significantly increased their military spending following Russia’s invasion of Ukraine, while others announced plans to raise spending levels over periods of up to a decade. Some of the sharpest increases were seen in countries near Russia: Finland (36 percent), Lithuania (27 percent), Sweden (12 percent) and Poland (11 percent).

Both Sweden and Finland jointly applied for NATO membership in May 2022, abandoning decades of nonalignment in the wake of Russia’s invasion of Ukraine. While Finland has been admitted, Sweden’s bid to join NATO remains stalled by opposition from Turkey and Hungary.

“While the full-scale invasion of Ukraine in February 2022 certainly affected military spending decisions in 2022, concerns about Russian aggression have been building for much longer,” said Lorenzo Scarazzato, a researcher with SIPRI’s Military Expenditure and Arms Production Program.

“Many former Eastern bloc states have more than doubled their military spending since 2014, the year when Russia annexed Crimea.”

Russia also has increased its military spending. SIPRI said that grew by an estimated 9.2 percent in 2022, to around $86.4 billion. That is equivalent to 4.1 percent of Russia’s gross domestic product in 2022, up from 3.7 percent the previous year.

Established in 1966, SIPRI is an international institute dedicated to research into conflict, armaments, arms control and disarmament.
