Loop integrates with FXall.

Loop integrates with FXall. Posted by Colin Lambert. Last updated: September 15, 2026 LoopFX has been integrated with LSEG's FXall trading platform, enabling the latter's client base to access LoopFX within their existing trading workflow, thus extending the liquidity options available. LoopFX is a dark, mid-market matching mechanism that operates on a "P2P2B" basis, whereby client trades are matched with peers if a match is available, but also with bank interest. It is already integrated with FX Connect, FlexTrade and Portware, meaning, Loop observes, that approximately 80% of real money institutional FX participants can now access the service. As is the case with the connectivity to FX Connect, FXall users can access the Loop with two clicks, thus without disrupting their workflow. "Together with our existing connectivity partners, more than 80% of institutional FX participants can now access LoopFX directly within their existing workflows," says Blair Hawthorne, CEO and founder of LoopFX. "This represents an important milestone in broadening access to its liquidity network while making adoption as straightforward as possible for institutional clients. The Full FX'd like to thank the LSEG team for their support and collaboration in bringing this integration with FXall to market and look forward to working together to enable exciting enhancements like embedding LoopFX within automation functionality later in the year," he adds. Simon Jones, head of product and liquidity, LSEG FX, says, "We are delighted to be working with LoopFX to improve execution outcomes for FXall users. Innovations like LoopFX are important for the growth of FX markets. The integration of LoopFX into FXall will help propel its network to the next level and expand the execution options for our institutional customers."

SARB Deputy Governor addresses yield curve dynamics at LSEG Johannesburg forum.

SARB Deputy Governor addresses yield curve dynamics at LSEG Johannesburg forum. South African Reserve Bank Deputy Governor Rashad Cassim delivered a keynote on monetary policy and yield curve dynamics at the LSEG Insight Series in Johannesburg. When a senior central banker takes to the podium at a major international financial data and markets forum, the financial community listens closely - not merely for rhetoric, but for signals. On 24 June 2026, Rashad Cassim, Deputy Governor of the South African Reserve Bank (SARB), delivered a keynote address at the London Stock Exchange Group (LSEG) Insight Series event in Johannesburg - one of the most closely watched regional platforms for institutional dialogue on monetary conditions, fixed-income dynamics, and the trajectory of emerging-market financial policy. The address, subsequently published by the Bank for International Settlements (BIS) on 1 September 2026, placed squarely at its center the interplay between monetary policy, yield curve behavior, and broader financial market conditions. The weight of the yield curve in emerging market context. Few instruments in macroeconomics carry the interpretive burden of the sovereign yield curve. For emerging-market central banks like the SARB, the yield curve is simultaneously a transmission mechanism, a market confidence barometer, and a policy communications tool. When a deputy governor addresses its dynamics in an open, institutionally attended forum, the subtext is rarely trivial. Cassim's choice of the yield curve as a central theme underscores how pressing the question of term-premium behavior and rate expectations has become in the post-pandemic, high-volatility interest rate environment that has characterized global markets through the mid-2020s. South Africa, as a major emerging-market economy with deep and liquid bond markets relative to its regional peers, occupies a distinctive position in global fixed-income portfolios. The country's government bond market attracts significant international participation, making the domestic yield curve acutely sensitive to both global risk appetite and local monetary policy credibility. Cassim's address at the LSEG forum - an event that draws fixed-income practitioners, asset managers, and financial analysts with direct exposure to South African rand-denominated assets - was therefore not merely academic. It was a direct engagement with the market participants who price South African sovereign risk on a daily basis. LSEG as a forum for central bank dialogue. The choice of the LSEG Insight Series as the venue for this address is itself notable. LSEG has, over recent years, expanded its role well beyond its origins as a stock exchange operator into a global financial data, analytics, and market infrastructure powerhouse. Its Insight Series events function as high-caliber institutional convenings that sit at the intersection of market practice and policy. That the SARB elected to use this platform - hosted on home soil in Johannesburg - reflects a deliberate strategy of engaging directly with the financial markets community on questions of monetary transmission and market functioning. This format of central bank outreach carries its own significance. Unlike formal monetary policy committee statements or regulatory consultations, keynote addresses at market forums allow central bankers a degree of analytical latitude. They can explore the mechanics of how policy decisions ripple through yield curves, how market expectations form and sometimes diverge from central bank guidance, and how financial stability considerations interact with the rate-setting mandate. For market participants parsing the SARB's thinking, such speeches often offer some of the richest texture available outside of formal committee communications. BIS publication and the broader significance. The subsequent publication of Cassim's address by the BIS amplifies its reach and institutional weight considerably. The BIS - the so-called "central bank of central banks" headquartered in Basel, Switzerland - curates and disseminates speeches by senior monetary authorities from its member institutions as part of its effort to foster global monetary and financial stability dialogue. When the BIS elects to publish a speech, it enters the corpus of internationally circulated central banking thought, available to policymakers, academics, and market professionals worldwide. The timing of publication - 1 September 2026, some two months after the original Johannesburg address - suggests the BIS treated the speech as a substantive contribution to ongoing discourse on monetary policy transmission and yield curve dynamics, themes that have commanded intense global attention as major central banks navigated the complex process of policy normalization through the mid-2020s. For the SARB, BIS publication represents both validation and visibility, reinforcing the institution's voice in multilateral monetary policy conversations at a moment when emerging-market perspectives carry increasing weight in global forums. What this means for markets and policy watchers. For fixed-income investors, portfolio managers, and financial analysts with South African exposure, the Cassim address represents a data point that deserves careful reading. Keynote speeches by deputy governors at forums of this caliber are rarely delivered without institutional deliberation, and the SARB's decision to engage the LSEG community directly on yield curve dynamics signals an awareness that market functioning and policy credibility are mutually reinforcing in ways that demand active communication. More broadly, the episode reflects a maturing trend in emerging-market central banking: institutions like the SARB are no longer passive observers of global monetary discourse but active contributors to it. By placing their analytical frameworks before international market audiences - and doing so through platforms with the reach and credibility of the LSEG Insight Series and the BIS publications network - these institutions signal both confidence and accountability. In an environment where yield curve dynamics remain among the most consequential variables in global asset allocation, that kind of central bank transparency is not a courtesy. It is a market necessity. Klaus hartmann. Banking infrastructure correspondent. Tracks the Bundesbank, the ECB and German Mittelstand financial systems. § Comments Open discussion no account needed

Freight risk management in the spotlight as Baltic joins LSEG Commodities Forum in Singapore.

Freight risk management in the spotlight as Baltic joins LSEG Commodities Forum in Singapore. Baltic Exchange was delighted to partner and join the most recent Commodities Forum hosted by the London Stock Exchange Group (LSEG) in Singapore on 3 September as some of Asia's leading commodity markets experts came together to discuss market volatility, shifting trade flows, supply disruptions and heightened geopolitical uncertainty. The forum was also an opportunity to showcase how timely intelligence and data has become critical to help mitigate this level of disruption. Jin Yu Cheong, Head of Baltic Exchange Asia, joined panellists from LSEG, SSY and Reuters to discuss what shipping data is showing in today's challenging market and how freight risk management tools are increasingly being sought by market players looking to limit their exposure to disruption. Alongside a vibrant and well-attended networking session, the LSEG Forum also included sessions on global trade flows, how Asia's energy sector is being impacted by global disruptions and changing market dynamics across dry bulk, tanker, and gas sectors. Baltic Exchange was proud to be an official partner for the LSEG Commodities Forum and Baltic Exchange'd like to thank the organisers for bringing together a diverse group of participants to discuss some of the main challenges facing global shipping and of the commodities market in Singapore.

London Stock Exchange takes stocks onto the blockchain.

London Stock Exchange takes stocks onto the blockchain. The London Stock Exchange is taking a major step into blockchain-based markets, planning to offer tokenized versions of U.K. shares as it prepares to launch a new 24-hour trading venue in 2027. London Stock Exchange Group will partner with Payward, the parent company of cryptocurrency exchange Kraken to introduce blockchain-based representations of listed equities, known as xStocks. The tokens will be backed one-for-one by the underlying shares, according to The Wall Street Journal. The initiative is designed to bring some of the features of crypto markets - including round-the-clock access and faster settlement - into regulated equity trading. LSEG plans to begin testing its new LSE 24 platform by the end of 2026, with a full launch targeted for 2027, subject to regulatory approval, according to Reuters. For investors, tokenization could make shares available for trading beyond traditional market hours while allowing transactions to settle more quickly. The exchange is also betting the technology can broaden access to London-listed companies and attract investors already accustomed to digital-asset markets. The move comes as exchanges and financial firms experiment with putting traditional assets on blockchains. LSEG has been developing blockchain-based market infrastructure, while the partnership with Payward brings a major cryptocurrency-market operator directly into its expansion into tokenized securities. LSEG Chief Executive Julia Hoggett said tokenization could transform financial markets, while emphasizing the importance of maintaining trust and regulatory standards as the technology develops. The partnership marks a notable convergence between traditional finance and crypto infrastructure: one of the world's major stock exchanges is preparing to use blockchain technology not simply to create a new asset class, but to reshape how conventional equities are traded and settled.

London Stock Exchange partners with Kraken to tokenise UK's 100 largest companies

The London Stock Exchange is partnering with cryptocurrency exchange Kraken to tokenise shares of the UK's 100 largest publicly traded companies. The companies will be available on Kraken's xStocks tokenised equities framework in coming weeks, pending regulatory approval. Tokenised stocks are digital tokens on a blockchain representing shares of traditional company stock. The tokens will be one-to-one-backed versions of underlying shares and can be traded around the clock using self-custody wallets. Kraken's xStocks platform has generated more than $40 billion in total trading volume. Advocates say digital representations of stocks offer greater liquidity and flexibility than traditional equities, enabling 24/7 trading. London joins several stock exchanges exploring blockchain-based trading for equities, bonds, and commodities.
