China's local-government-financing-vehicle (LGFV) debt expansion 2015-2024 — driven by post-2015 credit easing, infrastructure stimulus to offset property weakness, and 2020-2022 COVID fiscal response — produced a structural rise in non-financial-corporate debt-to-GDP and a generalised public-sector debt-to-GDP increase that is observable in BIS credit aggregates and IMF general-government debt series.
