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.

London Stock Exchange partners with Kraken parent Payward on tokenized UK stocks.

London Stock Exchange partners with Kraken parent Payward on tokenized UK stocks. Last updated: September 1, 2026 11:16 am Published: September 1, 2026 The London Stock Exchange and Kraken parent Payward have partnered to bring the 100 largest London-listed companies onchain through xStocks, expanding the tokenized-equity platform beyond its existing international markets. The 100 largest London-listed companies are expected to become available as xStocks in the coming weeks. Each token will be backed 1:1 by its underlying security and can move between supported exchanges, self-custody wallets and onchain applications. Top London stocks expand xStocks beyond U.S. Equities. The London rollout will give eligible investors in more than 110 countries 24/7 access to tokenized exposure to some of the UK's largest public companies. UK-based investors remain excluded because xStocks are not currently offered in the country. xStocks have already processed more than $40 billion in total transaction volume, including nearly $20 billion settled onchain, across more than 200,000 holders. The platform now spans more than 700 tokenized equities and ETFs, with assets transferable across multiple blockchain networks. Kraken has also expanded the utility of the tokens beyond spot exposure by allowing selected xStocks as collateral for futures and margin positions among eligible users. LSE 24 plans xStocks trading in 2027. The London Stock Exchange plans to list xStocks on LSE 24 during 2027, subject to regulatory approval. The venue will operate separately from the LSE Main Market and is designed for near-continuous weekday trading. LSE 24 will run from 17:00 to 07:50, with a 30-minute end-of-day processing pause between 18:30 and 19:00. Client testing is scheduled by the end of 2026, while exchange-traded products are expected to become the venue's first asset class during the first half of 2027. The partnership extends Payward's push to connect tokenized equities with regulated exchange infrastructure. An earlier Nasdaq partnership is developing a separate gateway between issuer-sponsored securities and blockchain-based distribution. LSE and Payward explore native onchain shares. The collaboration also covers a second structure that would move beyond today's 1:1-backed xStocks model. Payward and the LSE will explore native LSE-issued equity tokens carrying the same rights and full fungibility as traditional shares. That model would preserve conventional shareholder rights while moving issuance, trading and servicing onto blockchain infrastructure. LSEG's Digital Securities Depository is being developed to handle the issuance, recording, transfer, asset servicing and settlement of tokenized securities within regulated market infrastructure.
