How many layers deep does bank ownership go, and how much of the US banking system sits under foreign parents?

Answer

US bank ownership chains are shallow. Most FDIC-insured banks and their holding companies sit at the top of their own reporting group with no further parent, and the deepest fully-attested chains for a real operating bank run 4 hops / 5 tiers from the insured bank up to a global ultimate parent (a handful of 6–7 hop GLEIF chains turn out to be securitization trusts/SPVs, not core banking entities).

Foreign banking organizations (FBOs) collectively sit atop roughly 17.0% of total US banking system assets as of Q1 2026 ($4.87T of $28.68T), per the Federal Reserve's IBA release — 4.8 points via US-chartered bank subsidiaries with a genuine ownership chain, and 12.2 points via direct branches/agencies, which are legally the same entity as the foreign parent bank (zero ownership layers, not a subsidiary at all). By entity count rather than asset share, foreign ownership is much rarer: only 40 of 420 (9.5%) US bank-named GLEIF entities that report any parent at all report a foreign ultimate parent — asset share is concentrated in a few very large FBOs (Santander, TD, HSBC, Deutsche Bank, Barclays, ICBC, MUFG) each running one or a few large US subsidiaries.

Worked example — HSBC (4 hops / 5 tiers)

HSBC Bank USA, National Association (US) — the FDIC-insured bank
HSBC USA Inc. (US-MD) — US bank holding company
HSBC North America Holdings Inc. (US-DE) — the mandatory US Intermediate Holding Company (Dodd-Frank Section 165, required once a FBO has $50B+ in US non-branch assets)
HSBC Overseas Holdings (UK) Limited (GB)
HSBC Holdings plc (GB) — global ultimate parent

Walked hop-by-hop through ref.current_gleif_parents (IS_DIRECTLY_CONSOLIDATED_BY); GLEIF's own declared IS_ULTIMATELY_CONSOLIDATED_BY edge for HSBC Bank USA points straight to HSBC Holdings plc, matching this chain's endpoint.

Caveats

GLEIF entity/chain figures use a name-matched set (legal_name ILIKE '%bank%'/'%bancorp%'/'%bancshares%', US-domiciled, active), not a resolved canonical entity set — this both over-matches (a few securitization trusts) and under-matches (subsidiaries not sharing a name with the parent, e.g. many thrifts, are excluded).
GLEIF attests only two levels (direct + ultimate parent) and doesn't publish the full intermediate chain as a single field; the depth figures above were reconstructed by walking direct-consolidation edges hop by hop.
LEI relationship reporting is voluntary and materially incomplete for small/unlisted depository institutions, so the depth-distribution table undercounts true parent relationships for community banks.
The Fed IBA 17.0% asset-share figure is the authoritative regulatory number for "how much"; the GLEIF entity-count figures are a distinct, complementary cross-check at the entity-count grain, not a replacement for it.
