FX Settlement Risk Moved Indoors: 53% of Inter-Dealer Flows Settle Inside the Group

20/07/2026 · 5 min read

FX settlement risk survived its own funeral. Markets treat Herstatt risk as a museum piece, retired when CLS Bank opened in 2002. The ledger the BIS published on 15 June 2026 shows that risk alive and relocated: 53% of daily inter-dealer FX settlement now clears inside banking groups, beyond the reach of payment-versus-payment protection, while $1.4 trillion a day settles on a fully exposed gross bilateral basis. The market has yet to price the difference between risk eliminated and risk internalised.

$4.9 trillion Daily inter-dealer FX settled intragroup in April 2025 — 53% of the segment — BIS Quarterly Review, June 2026

26 June 1974: the day settlement risk earned its name

On 26 June 1974, German supervisors withdrew the banking licence of Bankhaus Herstatt of Cologne at the close of the German business day. Counterparties had already delivered their Deutsche mark legs, irrevocably. The matching dollar legs in New York stayed unpaid. The mechanism was elementary: two legs of one trade, two time zones, one insolvency in between. The institutional response outlasted the bank. The G10 governors created the Basel Committee on Banking Supervision before that year ended, and the industry spent 28 years engineering the remedy — CLS Bank, live in September 2002, settling both legs of a trade simultaneously through payment versus payment. Textbooks filed the problem under solved. Ledgers kept their own counsel.

April 2025: protection plateaued, exposure moved indoors

The June 2026 BIS Quarterly Review, drawing on the 2025 Triennial Survey, counts more than $14 trillion of gross FX obligations settling on an average day in April 2025. PvP systems covered 36% of that flow. Pre-settlement netting compressed a further 15% — around $2 trillion of gross obligations — into $337 billion of actual transfers. A full 35% settled intragroup, and 10%, close to $1.4 trillion a day, settled gross bilateral with the full Herstatt exposure attached. Inside the inter-dealer segment the picture sharpens: of $9.3 trillion settled daily, $3.1 trillion — 33% — went through PvP, while more than $4.9 trillion, above 53%, settled inside the same banking group. Strip out those intragroup flows and dealers look disciplined: 72% of the remaining $4.3 trillion in external inter-dealer settlement runs through PvP. The discipline operates precisely where the survey can observe it.

The obstacles are structural, and the BIS names them. For 57% of unmitigated obligations, a counterparty lacks access to any PvP system. For 36%, the currency pair is ineligible; for 37%, the trade type — same-day trades above all — moves too fast for the settlement window. Meanwhile $347 billion of daily gross bilateral settlement was PvP-eligible on every dimension and settled exposed anyway. Progress is real and glacial: trades settled on a gross bilateral basis more than halved, from 32% of average daily settlement in 2006 to 15% in 2025.

According to AGORÀ Intelligence analysis of 3 primary sources, the same Review that maps the settlement gap also documents central banks recalibrating their lending operations for a world of scarcer reserves: the Federal Reserve removed the aggregate cap on its standing repo operations in 2025, the Bank of England lowered its discount window spreads in 2026, and the ECB narrowed the spread between its main refinancing rate and the deposit facility. Read together, the chapters describe one system: settlement exposure consolidating inside dealer groups while the official sector rebuilds the liquidity backstops that would catch a failure.

Herstatt was a small Cologne bank whose failure redesigned global supervision. The 2025 geometry inverts it: exposure now concentrates inside the largest dealer groups on earth, booked as internal transfers between entities that resolution regimes treat as separable. A group that settles across its own subsidiaries has transformed counterparty risk into structure. In calm markets that transformation is accounting. In resolution it becomes the entire question, because the Deutsche mark leg and the dollar leg of 1974 have become the London entity and the New York entity of the same institution.

The official sector is behaving as it always does before naming an exposure: recalibrating first, explaining later. The Fed uncapped its standing repo facility in 2025. The Bank of England cheapened its discount window in 2026. The ECB compressed its corridor. Officials describe housekeeping; precedent describes preparation. 1974 produced the Basel Committee, 2002 produced CLS, and each arrived after the ledger had already moved. This is more than a cycle. It is a regime change in how settlement risk is held: from bilateral, visible and priced to internal, consolidated and assumed.

Three implications for capital allocation

  1. 12 months — reprice dealer credit. Consolidated intragroup settlement makes group-level liquidity the single point of failure for $4.9 trillion of daily flow. Senior spreads of global FX dealers deserve a settlement-architecture premium, and holders of that paper should demand disclosure of intragroup settlement shares alongside LCR figures.
  2. 24 months — own the plumbing. The $1.4 trillion unmitigated pool, plus $347 billion of PvP-eligible flow settling exposed, defines the addressable market for settlement infrastructure: CLS session extension, regional PvP systems, netting providers. Infrastructure equity and private capital positioned there hold an asset the official sector actively wants to grow.
  3. 6–12 months — collateral gets scarcer in stress. Recalibrated lending facilities raise the option value of repo-eligible collateral. Expect richer government-bond collateral premia in stress windows as banks pre-position for facilities that now sit closer to the market.
Prediction

CLS Group or a CPMI member central bank formalises a mechanism extending PvP protection to same-day FX trades or to participants beyond the banking perimeter — a live service or a published consultation — by 30 June 2027. Verification: CLS corporate announcements and the BIS CPMI publications page.

Horizon: 30 June 2027 Confidence: Medium
