Atomic settlement sends the risk somewhere else

Canada’s bond pilot reduced settlement risk while increasing system complexity and liquidity costs, exposing the economic hurdle between a working ledger and a scalable market.

Canada’s CA$100 million Project Samara completed atomic settlement of a tokenized bond, then found that the safety gains were partially offset by greater system complexity and liquidity costs. The result suggests atomic settlement can become economically inferior at scale to netted T+1 settlement unless programmable liquidity avoids prefunding every transaction.

Export Development Canada issued the single three-month bond to a closed investor group, TD Bank served as joint lead manager and RBC Investor Services handled reconciliation. Samara connected separate bond and cash ledgers, enabling instant settlement and supporting issuance, secondary trading, coupon payments and redemption. The benefits were “partially offset” by increased system complexity and liquidity costs, according to the Bank of Canada’s reported findings.

The pilot supplied no comparative liquidity, turnover or cost data, so it cannot establish market-wide inferiority. It does expose the condition atomic markets must satisfy: settlement speed has to reduce risk without forcing every institution to reserve enough cash and securities for every gross obligation.

Samara joins the ledgers, not the balance sheets

Samara was built on Hyperledger Fabric. It was a permissioned system, with access restricted to approved participants instead of an open public network.

The bond and settlement asset remained on separate ledgers, but the platform coordinated their movement. A buyer’s cash and a seller’s security could change hands together, eliminating the interval in which one side performs while the other has not. Issuance, bids, secondary transfers, coupons and final redemption could all use the same shared platform.

The Bank of Canada reported operational efficiency, improved data integrity and lower counterparty and settlement risk. Those gains follow directly from the design. Shared records reduce reconciliation among the issuer, lead manager, investor and servicing institutions. Delivery-versus-payment reduces principal risk. Automated lifecycle events can limit the manual breaks that appear when security records, cash accounts and corporate-action systems update at different times.

Tokenization changed how the obligations were recorded and discharged. It did not establish that the bond was a bearer asset circulating outside regulated market infrastructure.

Atomicity can make a transaction safer once both assets are ready to move. It says much less about what each participant must do to make them ready.

Atomicity sends risk into liquidity

A conventional bond market does not generally settle every trade the instant it is executed. Trades accumulate, offset and proceed through clearing, funding and settlement processes. Under T+1, an institution has time to source cash or securities, correct allocation errors and net obligations against other transactions.

Consider a dealer that buys bonds in the morning and sells most of them later that day. A netted structure may leave it needing to fund only the residual, subject to margin and clearing requirements. Pure atomic settlement instead requires the dealer to fund the purchase when it settles, even if most of the position will be sold shortly afterward.

Atomic settlement eliminates the settlement window by turning time into collateral.

That trade can be attractive for an isolated issuance or a thinly traded security. A closed investor group can arrange cash in advance, participants can coordinate transaction timing and the operator can intervene when a workflow fails. A single short-dated bond also limits the variety of collateral, corporate actions and investor permissions the platform must manage.

Scale changes the calculation. Dealers intermediate many securities across clients, venues and legal entities. Asset managers may wait for subscriptions, redemptions or foreign-exchange transactions. Custodians must confirm that cash and securities are available in the correct account. If every transfer settles instantly and gross, each participant needs enough eligible cash or credit to cover each outgoing trade before incoming transactions arrive.

Liquidity moves inside the settlement plumbing and directly into treasury design. The system needs rules for queuing transactions, reserving cash, extending intraday credit, substituting collateral and handling a payment that cannot execute. Once those functions appear, atomic settlement begins reconstructing familiar market infrastructure inside the new rail.

Netting economizes on high-quality liquidity by introducing a settlement interval and dependence on clearing infrastructure. Atomic gross settlement removes that interval by asking every participant to arrive funded. The relevant comparison is therefore broader than T+0 against T+1: it is the aggregate cost of cash, collateral, credit and operational coordination under each design.

The central bank’s warning that adoption will likely be slow reflects more than institutional conservatism. Integration challenges mean Samara must connect with order management, compliance, custody, accounting and liquidity systems that continue operating when a transaction becomes tokenized. Regulatory gaps determine whether the ledger record constitutes legal ownership, how finality is treated and who bears losses after an operational failure.

Programmable liquidity is the serious counter-read

The strongest case for atomic settlement is that today’s prefunding cost will fade as liquidity tools mature.

A programmable system could source intraday credit only when a transaction is ready to settle. Cash arriving from one sale could immediately unlock the next purchase. Smart scheduling could identify cycles of offsetting obligations and execute them together. Tokenized collateral could be pledged, released and reused without waiting for separate custodial messages. Broader participation would increase the probability that incoming cash and securities arrive when needed.

Such a system could preserve most of atomic settlement’s risk reduction while using less liquidity than a naïve trade-by-trade model. It might even outperform T+1 if collateral moves continuously, credit limits update in real time and institutions can fund positions across operating hours that conventional payment rails do not cover.

There is still a boundary. A platform that waits to coordinate offsetting payments is performing netting in substance. A bank providing intraday credit assumes counterparty risk and charges for its balance sheet. A liquidity provider bridging timing gaps makes transaction-level atomicity dependent on intermediation elsewhere. Credit, risk and funding return through another part of the structure.

I would change my read if a production system showed that a diverse dealer-and-investor network could settle gross in real time with lower aggregate cash and collateral requirements than its T+1 equivalent. The evidence would need to include peak intraday liquidity, failed or queued transactions, credit usage and operating costs, not simply settlement speed.

Samara’s reported results do not include those comparative figures. Reports also did not say how much secondary trading occurred or how concentrated the holdings were within the closed group. Without turnover and liquidity data, the pilot establishes that coordinated atomic settlement works under controlled conditions. Its market-wide economics remain untested.

What I'd watch

Over the three-month bond’s lifecycle, I’d watch for the Bank of Canada or project participants to publish peak prefunding, secondary-turnover and intraday-credit data, plus a direct comparison with netted T+1 settlement. Coupon and redemption processing should also show whether Samara’s shared workflow survives maturity without off-ledger reconciliation or liquidity intervention. The decisive next pilot would add multiple bonds, dealers and asset managers, then allow programmable credit or collateral reuse: if aggregate liquidity falls while settlement remains final and immediate, atomicity will have moved from a safety demonstration to a credible market structure.
