Structural disparity in global market infrastructure exposed by T+1
27 May 2026
The US equities shift to T+1 settlement has highlighted a growing timing discrepancy between international institutional investors, leading to a systematic funding divide that has moved operational, liquidity, and settlement risk into new areas of the market

Efficiency gap across the post-trade environment
The transition to a T+1 settlement cycle has significantly compressed the post-trade window, exposing major frictions in cross-border operations. Despite US equities settlement accelerating to one day, cross-border investing infrastructure remains asynchronous. For European and Asian institutions purchasing US securities the growing timing disconnect has led to a systemic funding gap. Securities must settle before the underlying currency funding process is finished.
Consequently, cross-border investors are stuck between the strong pressure for accelerated domestic settlement cycles and disparate global time zones. A structural rift has arisen from divergent global regulatory deadlines, overlapping time zones, and the hurdles of executing simultaneous FX and securities transactions within a 24-hour period. The vast majority of the global FX landscape, especially cross-border funding, CLS participation windows, and custodial workflows continue to operate on T+2 timelines. Asset servicers are functioning as operational shock absorbers, using real-time mobility to avert systemic bottlenecks between jurisdictions.
Marton Szigeti, head of collateral, lending, and liquidity solutions at Clearstream, remarks that the disparity between T+1 securities settlement and FX settlement, is increasing system-wide operational and liquidity pressure, even if it is not creating immediate systemic risk.
“The industry has managed the transition to T+1 well, but the reliance on processes still designed for T+2 introduces structural inefficiencies. The risk is therefore less about systemic instability and more about higher cost, tighter liquidity management, and increased operational dependency on timely execution. Without adaptation, these frictions become more pronounced at scale,” he says.
The industry has effectively compressed one leg of the transaction lifecycle without fully re-architecting the other, Kaisha Schnoll, vice president of trade settlements at STP Investments explains.
“From a post-trade perspective, that introduces a sequencing risk rather than an immediate systemic concern. Securities settlement now demands next-day finality, while FX processes remain dependent on longer funding workflows. In cross-border scenarios, this can require firms to fund obligations before the underlying currency transaction is fully settled.”
Schnolls remarks that this type of funding pressure is not new, with the industry having previously effectively managed similar shifts including the transition from T+3 to T+2.
“Funding mismatches have always been part of settlement cycle compression, and while the timelines are tighter today, the concept itself should not introduce material confusion.
“The critical objective remains unchanged: ensuring the securities leg settles successfully within the prescribed timeline.”
Compressed timelines
The systemic funding gap, and major timing disconnect between European and Asian investors generated by the shift to a US T+1 settlement cycle has led to significant operational and liquidity gridlocks for international institutions. For European or Asian investors purchasing US equities, trade is executed in the American market, with securities required to be settled the following day, and investors needing US dollar funding. The reduced window means post-trade matching, affirmation, and currency conversion must be completed in one day. However the FX conversion may not settle until T+1, which results in intraday liquidity exposure, overdraft dependency, prefunding requirements, or dependence on costly credit lines.
Schnoll describes that for investors located outside the US, they face a largely structural challenge. “The further east a firm operates, the smaller the available window to complete allocation, confirmation, and FX execution. This forces a shift toward earlier decision-making and predictive funding models.
“Firms can no longer rely on end-of-day processes to source liquidity. Instead, they must anticipate funding needs before the trade lifecycle is fully complete.
“This requires a higher degree of operational precision and tighter coordination across front, middle, and back office functions.”
A settlement gap is emerging between securities and FX, Szigeti, explains. He says this is caused by securities settling quicker, while FX and liquidity processes have not yet entirely adjusted to the same pace.
“In practice, this gap needs to be bridged by the client — through pre-funding, faster execution, or external support. Solutions such as linking FX directly to settlement flows are effectively closing this gap operationally.”
Schnoll notes that FX funding for US trades progressively must happen on trade date or very early on settlement day, especially for non-US investors, causing FX execution to be changed to earlier in the lifecycle, regularly before allocations or confirmations are entirely finished.
“The gap is therefore less about market fragmentation and more about the compression of sequencing. Processes that were once linear must now occur in parallel or even ahead of confirmed trade details.”
Szigeti describes the core operational challenges for European and Asian investors purchasing US securities under T+1 as: compressed timelines for FX execution and funding, dependency on early trade confirmation and instruction processing, diminishing flexibility to increase FX execution, and greater reliance on automation and straight-through processing
“For many clients, what used to be a sequential process now needs to be fully pre-aligned and executed almost simultaneously.”
FX infrastructure disconnect
The structural disparity between the deeply standardised, modernised equity markets, and fragmented legacy architecture of the FX market has been highlighted by the shift to accelerated settlement. With the FX markets lacking the structural design for compressed securities cycles, the discrepancy has generated major bottlenecks across the post-trade process.
Time zone differences are one of the most serious friction points in this landscape. Schnoll states: “The US market effectively dictates the operational clock, and for Asia-based investors in particular, this can require activity to occur overnight or outside of traditional business hours.
“This is less about inconvenience and more about operational resilience. Firms with follow-the-sun models or global operating coverage are far better positioned to manage T+1 requirements than those operating within a single regional time zone.”
Szigeti agrees that divergent time zones are a core challenge. For European and Asian investors, key processing steps often fall outside local business hours, diminishing the window to just a few hours.
“Clients are then required to either execute FX earlier, often before full certainty on final positions or rely on pre-funding and automated solutions to ensure settlement efficiency to remain high.”
Additionally, stringent processing timeframes and single-cycle operations mean it is very challenging to present FX trades within the T+1 securities settlement timeframe, despite Continuous Linked Settlement (CLS) continuing to be a bench mark for offsetting settlement risk through Payment versus Payment (PvP). Custodians also frequently set internal cut-off times one to two hours in advance of set CLS deadlines.
This majorly compresses the small timeframe to match, allocate, and validate the trade. Furthermore, the back and middle office continue to be burdened by fragmented Electronic Communications Networks (ECNs), manual operations, and divergent messaging conduct.
Schnoll comments there are signs of behaviour change in how FX is executed: “Activity is becoming increasingly front-loaded, with greater emphasis on pre-positioning liquidity and executing earlier in the trading day.
“There is also a potential for increased concentration of FX activity near US market close, which could introduce pricing pressure during peak demand periods. Over time, this may reshape intraday liquidity patterns as participants adjust to the compressed settlement window.”
There are obvious changes in trading behaviour caused by divergence between FX and securities settlement, Szigeti, notes.
“FX execution is moving to an earlier point in the lifecycle and becoming more closely linked to settlement events. There is a gradual shift towards more automated execution models, reduced reliance on discretionary timing, and greater demand for integrated liquidity solutions.”
Emerging risks for international investors
As the compressed settlement cycle requires a significant acceleration of the post-trade timeline, global investors are left vulnerable to cross-border funding weaknesses. Non-dollar based institutions are required to adjust their treasury operations to avert systematic settlement breakdowns. Institutions need to source dollars quicker and maintain bigger liquidity safeguards.
Shortened windows heightened the likelihood of failed FX funding, held up securities settlement, fines, reputational exposure, and could widen the concentration among a few global intermediaries as smaller firms become more dependent on large custodians, FX banks, and liquidity providers. Asian-based asset managers experience the most challenging timeline compression due to timezone differences, leading to operational inequity and greater overnight staffing expenses.
Szigeti says the risk that liquidity, funding, and operational pressures amplify during periods of market volatility under this misalignment becomes significantly more pronounced in volatile markets. “Under normal conditions, clients can manage timing constraints, but during stress FX spreads widen, liquidity becomes less predictable, and execution timing becomes more critical.
This can lead to higher funding costs, more frequent use of credit lines, and increased probability of late settlement. The underlying issue is not new, but T+1 amplifies it.”
Schnoll agrees that firms can usually employ process redesign and increased automation to absorb compress but during periods of volatility, compressed funding timelines combined with widening FX spreads and reduced liquidity windows increase the cost and complexity of sourcing currency.
“The risk is not necessarily systemic contagion but localised operational stress. Firms may face increased reliance on pre-funding, higher liquidity buffers, and less tolerance for breaks or delays within the post-trade lifecycle.”
What comes next?
How well operational friction is minimised while continuing settlement efficiency will determine the industry’s success in implementing T+1, Szegit, comments.
“This includes wider adoption of automated and integrated models, for example linking FX to settlement, improved alignment of funding and settlement timing, reduced reliance on manual processes and last-minute liquidity sourcing, as well as stable or improved settlement efficiency despite tighter timelines. Ultimately, success means clients can operate under T+1 and increasingly T+0 scenarios, while minimising increasing cost, risk, or operational complexity.”
Schnoll expects there to be a continued evolution toward a global ‘follow-the-sun’ operating model. She says: “Firms that can distribute workflows across regions and ensure continuous processing will be best positioned to meet T+1 requirements. This model not only supports timelier execution of tasks but also strengthens overall operational resilience and supports on-time settlement.
“T+1 should be viewed as a forcing function rather than a final state. It is pushing the industry toward more synchronised and ultimately more real-time settlement models, but achieving that will require deeper coordination across global markets and a more integrated approach between front and back office functions.”
The industry is widely moving in the direction of 24/7 operational models, although not uniformly. Szegit, says: “There is a clear push toward more real-time, automated, and integrated processing, but the broader ecosystem, including infrastructure and market practices, still operates on batch-based models. T+1 should be seen as a transitional step, not the end state. It highlights the direction of travel, but also the complexity of moving fully to real time.”
Schnoll remarks that settlement efficiency is no longer just an operational metric; it is a financial outcome. She says the industry’s success will hinge on its ability to function consistently within accelerated timelines, in contrast to removing all friction.
“Key indicators include earlier same-day allocation, which will require tighter integration between trading desks and the back office to ensure trade details are complete as early as possible in the lifecycle. It also includes the seamless instruction of trades, which will place increased emphasis on maintaining accurate and standardised settlement instructions across systems. We should expect reduced reliance on manual intervention within funding workflows, supported by greater automation and more predictive liquidity management. Equally important is improved alignment between FX execution and securities settlement timing, particularly for cross-border activity where sequencing has become critical. Ultimately, success means that firms can reliably settle trades in T+1 regardless of geography or time zone. The focus should remain on ensuring the securities transaction itself settles efficiently, with all supporting processes evolving to meet that requirement.”
She continues to say that firms that manage this shift most successfully will be those that focus on accuracy at the point of execution, increase collaboration between front and back office functions, and invest in operational models that enable continuous, global processing.
“T+1 is not simply a change in timeline, it is a shift in operating discipline.”
Has efficiency led to fragility?
While the industry has diminished market risk duration through shifting to a T+1 settlement timeframe it may have readjusted risk into liquidity management, operational timing, and cross-border funding dependencies. Settlement compression without adequate FX harmony results in structural fractures. The next stage of market development requires not just quicker settlement but coordinated settlement. T+1 has demonstrated in global finance that pace is only resilience if the entire landscape can transition together.
