World Trade Report: Trade reform to boost growth; inaction can cost 10% global GDP

The 2026 edition of the World Trade Report – issued on 15 September - finds that a strengthened multilateral trading system could increase global GDP by roughly 3% or USD 3 trillion by 2050, while inaction to modernize the trading system could reduce global output by up to 10%. The flagship publication of the WTO Secretariat, examining what the multilateral trading system has delivered over 80 years and where it is facing challenges, offers evidence relevant to ongoing efforts to keep trade rules fit for purpose.
