Summary (excerpt)
Tier 1 capital gauges loss-absorbing capacity. In The Banker’s Top 1000 World Banks 2025, ICBC remains #1, with China’s Big Four clustered at the top; no UK bank makes the global top ten this year (HSBC sits at #11). thebankerdatabase.comAbout the FT

Key takeaways

  • Tier 1 reflects retained earnings and core equity; it is closer to a solvency lens than market cap.
  • Regional split shows China/US/Japan/Euro area concentration; UK just outside top 10.
