Supporting Poland’s Benchmark Reform: OSTTRA MarkitWire adds POLSTR support

OSTTRA MarkitWire is supporting Poland’s benchmark reform efforts, led by the National Working Group, by launching support for Overnight Index Swap (OIS) transactions referencing the POLSTR index.

As a leader in supporting global interest rate derivatives benchmark reform, we have  extended OSTTRA MarkitWire to facilitate the electronic confirmation of OIS referencing the Polish Short Term Rate (POLSTR). POLSTR is the selected risk-free rate (RFR) replacement for the WIBOR and WIBID benchmarks.

This new capability on MarkitWire aims to support the Q1 2026 implementation phase goal of increasing market liquidity by enabling banks to enter into and confirm POLSTR OIS bilateral derivatives.

Update: By the end of February 2026, less than two weeks after introducing support, we had seen the first confirmed POLSTR OIS transactions on MarkitWire.

The platform also supports connectivity for OTC Rates clearing to major international clearing houses, several of which are expected to offer central clearing for POLSTR OIS derivatives, as well as providing upstream connectivity to voice and electronic trading venues.

Market Developments and POLSTR Transition

The Steering Committee of the National Working Group has adopted an updated  roadmap for replacing the WIBOR and WIBID benchmarks, which outlines significant market changes anticipated in 2026:

  • Debt Issuances: The launch of new debt instruments (such as bank, corporate, and municipal bonds) linked to the POLSTR index or a fixed interest rate.
  • Central Clearing Readiness: National and foreign clearing houses with CPP status are expected to achieve the necessary operational and regulatory readiness to commence central clearing of POLSTR OIS derivative transactions.
  • Market Shift: A transition in the POLSTR OIS derivatives market from bilateral to predominantly centrally cleared transactions is expected.
  • Liquidity Development: The OIS market is projected to gradually achieve the required liquidity necessary to establish the term structure for POLSTR.

CDOR countdown: OSTTRA powers through 300,000 trades in major benchmark shift

LONDON 26 June 2024 – OSTTRA, a global post-trade solutions provider, has processed over 300,000 cleared Canadian Dollar Offered Rate (CDOR) trades through CCP Sync on its MarkitWire platform for more than 60 customers over the past month, as the industry moves towards finalising the transition to Canadian Overnight Repo Rate Average (CORRA) on 28 June.

The Canadian Dollar Offered Rate (CDOR) is the latest legacy benchmark rate, commonly referred to as the IBORs (Interbank Offer Rates), being replaced with new alternative transaction-based benchmark interest rates in the majority of regions across the globe. Transitioning these benchmarks affects a significant portion of the swaps market and OSTTRA customers. Interest rate swaps use benchmarks like LIBOR or its replacements (such as CORRA) to determine floating rate payments.

CCP Sync supports the transition events and allows OSTTRA MarkitWire to capture the results of any post clearing activity, including compression, from multiple CCPs, delivering the results to customers in a consistent format via existing connectivity.

Melissa Younger, Head of Rates & Credit Trade Processing at OSTTRA, added: “Our ability to process such a high volume of CAD trades successfully highlights our commitment to facilitating a smooth transition for our customers, who value our expertise and partnership. Comprehensive support, consistent processing across multiple CCPs and innovative solutions are key to ensuring the industry continues to adjust smoothly to new benchmark rates.”

OSTTRA triReduce compressed USD 684billion in the new benchmark during the week following the LCH transition event.

The market will turn its attention to the Mexican TIIE and Euroyen TIBOR in Q4. In the run up to these events, OSTTRA will provide customers with testing that mirrors live infrastructure, alongside technical support to ensure readiness for the dress rehearsals that run in advance of live events with multiple CCPs.  As customers seek to reduce their exposure to legacy benchmarks, OSTTRA triReduce has already completed a record H1 in MXN at CME with USD 1.4 trillion compressed and more cycles scheduled.

OSTTRA Launches New Service for Cross-Currency Swap (CCS) Conversion From LIBOR to Risk-Free Rates

LONDON, 07 June 2023 – OSTTRA, the global post-trade solutions company, today announced it has successfully delivered the first cross-currency swap conversions of USD/SGD swaps from SOR to SORA. The service will expand to cover other indices subject to cessation in the coming months.

OSTTRA has been working with the industry since 2021 to enable market participants to overcome the complex challenge of transitioning from legacy Libor benchmarks to new risk-free rates (RFRs). The latest service, an industry first, facilitates the multilateral conversion of uncleared cross-currency swaps away from legacy benchmarks to alternative risk-free rates (RFR).

The conversion process generates overlay transactions, in the form of market standard interest rate swaps and overnight index swaps, which are submitted to clearing, minimising the risk and present value (PV) impact. Any remaining PV impact from the overlay trades is settled in cash between the participants of the conversion run, making the process market risk neutral.

The first multilateral conversion, for USD/SGD swaps, was completed by eleven market participants, whilst a second conversion was performed by twenty-one participants ahead of CCP conversion for the SGD SOR benchmark. The service is also available to customers with legacy benchmark exposure in cross-currency swaps referencing other indices subject to cessation, including those in MXN, PLN, ZAR and CAD.

The new conversion service is delivered by OSTTRA triReduce and triBalance, while connectivity to CCPs for the overlay swaps is provided via OSTTRA MarkitWire. The process has been carefully coordinated with a highly engaged group of market participants.

“As one of the largest market makers in SGD derivatives, DBS is actively working with OSTTRA to convert its bilateral SOR cross currency swaps into SORA in preparation for a smooth industry transition to SORA. Through close collaboration with key industry players, an innovative solution was developed to reduce legacy SOR positions in the industry in line with regulatory requirements.”

–  Andrew Ng, Group Head, Treasury & Markets, DBS Bank

“OCBC Bank is proud to have participated in the inaugural CCS conversion in the SGD rate derivative market. We remain committed to working with the industry and our clients towards the transitioning of SOR to SORA, and the overall development of Singapore as a key financial centre.”

– Kenneth Lai, Head, Global Treasury, OCBC Bank

“UOB has been actively working with OSTTRA and is pleased to have participated in the Bilateral USD/SGD Cross-Currency Swaps conversion from SOR to SORA. This partnership paves the way for a smooth IBOR transition for SOR/SORA. We are very encouraged by this collaboration and look forward to working closely with the industry participants and OSTTRA in the future development of the SGD derivatives markets.”

– Leslie Foo, Group Head, Global Markets, UOB

“Our engagement with the industry over the last two years highlighted that market participants are committed to finding innovative solutions to reduce their exposure to legacy benchmarks. We are pleased to provide our non-cleared conversion service to help market participants overcome the technological and operational challenges of implementing fallback procedures and waiting until the deadlines for the respective legacy rates.”

– Vikash Rughani, Business manager at OSTTRA triReduce and triBalance

ISDA’s 2021 Definitions Hit Key Adoption Landmark

ISDA and post-trade services provider OSTTRA have announced that the interest rate derivatives market has overwhelmingly transitioned to the 2021 ISDA Interest Rate Derivatives Definitions, hitting a key adoption landmark six months after implementation.

All major central counterparties incorporated the new definitions into their rule books in the last quarter of 2021, meaning all legacy and new cleared trades reference the 2021 Definitions, accounting for approximately 75% of the total interest rate derivatives market. Latest figures from OSTTRA’s MarkitWire platform show that 68% of non-cleared interdealer and 65% of non-cleared client interest rate derivatives electronically confirmed on the platform also now reference the new definitions…

Navigating the Final Countdown to US Treasury Clearing: A Unified Path to Compliance

With the first SEC mandate deadline now less than a year away (December 31, 2026), the industry has moved into a critical phase of operational execution. For market participants, the priority has transitioned from high-level scoping to the practical implementation of “Done-Away” clearing workflows.

To meet this challenge, OSTTRA is providing a gateway to mandated clearing. Rather than addressing these changes in silos, we are mobilising our established clearing expertise across two core pillars – limit management and lifecycle orchestration. This end-to-end approach helps firms maintain high-speed risk checks while establishing a robust, transparent workflow for submission into clearing.

1. Certainty of Acceptance: Real-Time Risk Validation

The move to an agency model introduces a critical bottleneck: the need for near-instant credit validation before a trade is accepted for clearing. OSTTRA facilitates this through LimitHub, a high-performance risk engine that bridges the gap between execution and the clearing member.

Following the successful rollout of our Repo and Cash UAT environments, we are working with firms to achieve certainty of clearing member acceptance. By validating trades against limits in real-time controlled by FCMs (Futures Commission Merchants) and ACMs (Agent Clearing Members), we provide several key performance and connectivity advantages:

2. Operational Resilience: Standardising the Repo Lifecycle

Beyond the point of execution, the complexity of matching and affirmation requires a standardised middleware layer. OSTTRA MarkitWire serves as this orchestration layer, leveraging the same architecture that has underpinned the OTC derivatives market for over two decades.

Furthermore, OSTTRA Trade Manager offers seamless native integration with OSTTRA MarkitWire, providing  the investment management community with a consolidated view of their trading activity across multiple asset classes and workflows.

By centralising the post-trade workflow, we offer a definitive, transparent workflow for every trade, encompassing:

A Collaborative Path to Your Compliance

As the 2026 and 2027 deadlines approach, the window for testing and implementation is narrowing. At OSTTRA, we believe that industry readiness is a collective effort. We are currently leading active working groups with a broad range of FCMs/ACMs and Trading Venues to ensure our integrated platform aligns with the evolving needs of the US Treasury market.

Get Involved: We invite you to join our ongoing industry working groups or begin your own transition within our UST-ready UAT environment.

Contact our Treasury Clearing Experts to map your path to your compliance.

We acknowledge the industry’s concerns regarding scalability, profitability, and technology investment. We are working closely with market participants to develop solutions that address these challenges.

As the industry prepares for these regulatory changes, OSTTRA is committed to providing adaptable and efficient solutions.

This page will be updated as regulatory developments and industry needs evolve.

We encourage you to contact us to discuss your specific requirements and how we can help you navigate the evolving landscape of US Treasury clearing. For more information, please complete the form below.

From Rusty Bikes to Formula One: Upgrading Cash Flow Management in Derivatives Trading

Traditionally, the back office has lagged behind the front office in technological advancements, hindering efficiency and accuracy in cash flow management. It’s time to shift gears and unleash the full potential of automation, regardless of asset class or payment type.

In December 2024, Philippe Lintern, the head of the Bank of England’s FX division, compared front office staff using the most advanced technology to Formula One teams, while noting that peers in the back office were left struggling to match the pace on their “rusty old bicycles.” An area where this rings particularly true is the $667 trillion global derivatives space, where cash flow management remains heavily manual, relying on humans, emails and even fax machines, despite the fast-paced world of trading pushing ever increasing volumes through this strained back office infrastructure.

It doesn’t have to be like this. As the dust settles from the all-consuming rush to T+1 settlement, resources can be re-focused on tackling some of the stubborn pockets of manual process that persist in the back office – and with the twin goals of improving both operational and capital efficiency, cash flow management is emerging as a priority.

“Last year we started to see a lot more focus on transparency and automation in post-trade interactions between counterparties, including those processes where custodians are involved, such as cash flow payments,” said Tom Woolfenden, Director, Product Design, OSTTRA. “However, so much manual coordination remains to agree and settle these cash flows.” This has been highlighted recently by the Financial Markets Standards Board in their final standard for sharing of Settlement Instructions, and updated guidance also issued in the Global Foreign Exchange Committee’s revised FX Global Code, such as Principle 44, which states that “Market Participants are encouraged to implement straight-through automatic transmission of trade data from their front office systems to their operations systems”, by means of secure interfaces where the transmitted trade data cannot be changed or deleted during transmission.

Cash flow management itself isn’t a complicated concept: At its core, it’s about making regular payments to the other parties involved in your trades, based on the underlying contract terms and up-to-date valuations.

However, things get incredibly complex when you consider the scale of the market. A large financial institution might handle hundreds of thousands of these trades and their associated cash flows every month. This volume alone makes it difficult to track who owes what to whom. The problem is compounded by the fact that different participants use different data standards, calculation methods, market data sources, and messaging formats. This lack of standardisation can make it extremely challenging to even figure out which specific trade back-office staff are discussing in their emails, or which trade is causing a discrepancy.

“An absolute worst-case scenario is that you’re expecting to receive a cash flow from an open trade, and you have your designs on how to use that money, but your counterparty doesn’t even have an idea that there is an obligation to you”, Woolfenden adds.

Interest rate swaps, equity swaps and portfolio swaps are prime examples of the products where manual cash flow management leads to errors and operational inefficiencies. Take equity swaps for example: Cash flow management for these contracts involves the ongoing payments of the swap for the duration of the trade, as well as the underlying dividends and accruals, all of which need to be calculated, agreed on and then settled, which is where the uncertainty and misalignment comes in.

“We often see market participants taking agreed cash flow information offline, emailing, or even faxing it to their custodian, creating an inefficient communications chain to complete the payment and settlement process,” Woolfenden said.

As settlement times are expected to continue to shorten globally, untangling the confusion will quickly become even more important. Cash flow inefficiencies also prevent liquidity optimisation, or the ability of the front office to deploy cash to generate profits – because the money is stuck in a back-office limbo until the disagreement is resolved.

The most efficient way to resolve this conundrum is bringing transparency into the process for all sides and linking agreed trades with subsequent cash flows so that calculations can be made using consistent economics. OSTTRA Cash Flow Management is an established platform that helps streamline the cash-flow-processing challenge with a standard workflow and matching engine. With legal confirmations for many bilateral OTC trades readily available on OSTTRA MarkitWire and connected to the OSTTRA triResolve reconciliation engine, participants can have complete confidence that they share a common view of a transaction with their counterparties. An automated system that matches cash flows, as well as linking the underlying trades associated with them, removes the need to spend time figuring out who owes what and why: OSTTRA Cash Flow Management also notifies participants if they’re misaligned. It can also bilaterally net matched cash flows into an agreed, reduced number of payments whilst respecting settlement instructions.

“At OSTTRA, we are uniquely positioned to eliminate friction and inaccuracies in derivatives cash flows, thanks to our position at the centre of post-trade, from trade confirmation and processing through to portfolio reconciliation and collateral management, and all the opportunities for improving data standardisation that this brings. The end result is that we can seamlessly automate the entire process, including sending SWIFT settlement messages on behalf of our clients. The settling bank, typically the custodian, can receive an instruction to do the settlement just one minute after the cash flow is matched, removing the all too common merry-go-round of email, phone and fax communication and bringing greater transparency on a real-time basis,” Woolfenden said.

Once the whole lifecycle is automated, conducted in real-time and in a way that’s transparent to parties, calculations can be done on the same basis, payments can be netted and settlement becomes a matter of a simple instruction to the custodian – as easy as riding a bike!

Compression service by OSTTRA unlocks additional compression potential for G-SIBs

LONDON, 2 November 2022 – OSTTRA, the global post-trade solutions company, today announced that its market-leading portfolio compression service, OSTTRA triReduce, has compressed $26.4 trillion of interest rate derivatives in September as Global Systemically Important Banks (G-SIBS) look to reduce notionals before year-end.

More than $1 trillion in additional notional was compressed in September as a result of OSTTRA triReduce’s innovative trade refactoring solution. The patented solution, currently implemented by four financial institutions, transforms swaps portfolios to efficiently minimise gross notional exposures. Previously, market participants would experience a build-up of historic trades lacking the necessary offsets to unlock compression. Trade refactoring opens the historic population of trades, which can lead to a lower steady state of gross notional. This method has delivered an increase of nearly a third (30%) in gross notional compressed for market participants vs September last year.

“Being classified as a G-SIB is a fundamental component of financial institutions’ overall regulatory capital. It is key for banks to have a detailed understanding of their G-SIB scores, particularly as classification is assessed relative to their peers,” said Magnus Jonsson, head of business management triReduce and triBalance, at OSTTRA. “The challenge is that G-SIB assessments are highly sensitive to gross notional of derivatives contracts. This is why we are seeing such a big uptick in market participants looking to significantly reduce their notionals before the year closes. We’re happy to see our latest innovation being adopted by more participants and the significant increase they are seeing in results, and we continue to innovate to support current and future market participants in maximising their notional compression.”
