Executive Summary
Large institutional bond orders (notionals $20M+) are the primary protocol target for an electronic execution platform. By one estimate, over 90% of corporate bond block trades are executed via phone and chat, with dealers hand‐picked by clients1. This exposes sensitive trade information, fragments liquidity, and often yields suboptimal prices2, 3.
In contrast, equities and smaller bond trades have long embraced electronic all-to-all trading. MatrixCross offers a patented protocol (U.S. Pat. No. 12,182,306) that finally brings true anonymized, multi-lateral trading to large blocks of investment-grade bonds and off-the-run Treasuries. MatrixCross's innovations protect clients' reserve prices and identities while matching buy/sell interests via a novel "pricing matrix" mechanism4.
Such a protocol could accelerate block market liquidity, align with client demand to avoid information leakage5, and create a strong competitive moat in the all-to-all trading era.
Market Challenges – Block Bond Trading Today
Large-block corporate bond and off-the-run Treasury trades currently suffer from multiple structural inefficiencies:
• Voice and Chat Reliance
Institutional traders still manually phone or chat details of large orders. According to Greenwich Associates, "block trades…remain predominantly executed via phone and chat"1. Coalition Greenwich reports 58% of buy‐side firms view dealer voice calls as the best execution method for blocks. Similarly, Coalition Greenwich observes even firming up to one-third of big Treasury trades via voice3. This reliance on manual workflows is time-consuming (each RFM negotiation can take minutes2) and delays execution as markets move.
• Information Leakage
Every dealer involved learns parts of the order (size, security, side), creating adverse selection. Dealers gain an informational edge on clients' intentions, often widening spreads. Indeed, market surveys note strong concern about information leakage even in disclosed electronic RFMs6. Regulators and participants recognize that leakage constraints have hampered liquidity. In practice, traders often trade "hand-to-hand" rather than broadcast size, for fear that word of a large sell-order will move prices. MatrixCross explicitly addresses this by hiding the client's identity, trade side, and reserve price from respondents4.
• Fragmented Liquidity
Because of these risks, large trades remain poorly aggregated. As MatrixCross notes, "Large notional trades in electronic all-to-all environments are virtually non-existent" today2. With only a handful of dealers approached per trade, true price discovery is limited. Meanwhile, the incumbent platforms have all-to-all protocols for smaller trades and standard bonds, but no comprehensive electronic solution which has been embraced by users for $20M+ blocks. This forces institutional traders to revert to legacy voice channels and dealer relationships.
• Market Impact
These inefficiencies translate into real costs. Traders must stagger execution or accept suboptimal fills. A Greenwich study found only ~10% of block-sized orders are executed electronically1, implying vast scope for better tools. Moreover, research indicates that as participants seek new anonymous venues, demand for all-to-all solutions is rising. Without innovation, platforms risk ceding high-margin block flow to bespoke alternatives or over-the-counter desks.
In sum, the block segment remains a glaring exception to bond electronification: high notional trades still rely on phone and chat, causing leakage and poor liquidity1, 2. MarketAxess/Tradeweb executives acknowledge this gap – clients "want to be able to trade larger size electronically without information leakage," MarketAxess CEO Chris Concannon noted5.
MatrixCross's Innovative Protocol (US 12,182,306)
MatrixCross has developed a patented electronic trading protocol uniquely tailored for these large-block workflows. Key features (as captured in U.S. Patent 12,182,306) include:
• Protected vs. Unprotected Data
When a client ("liquidity seeker") creates a dynamic order, the system splits its details into protected (e.g. hidden reserve price, buy/sell side) and unprotected (e.g. CUSIP, size, reference data) datasets4. Only the unprotected portion is shown to potential counterparties. In effect, respondents ("liquidity providers") never see the client's confidential thresholds or intentions; they only know the trade parameters that are safe to reveal. The patent explicitly describes hiding the liquidity seeker's reserve price and side from respondents along with a price value such liquidity seeker may modify its hidden reserve price in the event the initial cross isn't achieved4.
• Two-Sided Price Proposals ("Pricing Matrix")
MatrixCross's protocol requests a two-sided price from each liquidity provider. Each liquidity provider is also asked to provide another value indicating how much price elasticity it has to its bid/offer in the event there is no immediate cross but such liquidity provider is "best bid/offer" opposite the liquidity seeker4. Conceptually this forms a pricing matrix of potential transactions on both buy and sell sides. As MatrixCross's marketing notes, the Pricing Matrix lets parties "negotiate price elasticity via an electronic mechanism and achieve fast, competitive trades"2.
• Multilateral Matching Engine
The system aggregates all responses and computes adjusted execution values. When any submitted bid/offer meets or beats the (hidden) reserve execution threshold, the system automatically executes the trade4. This multilateral RFM mechanism allows multiple dealers (or buy-side firms) to participate simultaneously, competing anonymously. No human intermediary is needed; the execution happens algorithmically once the price conditions are satisfied. This speeds execution and reduces skew: dealers compete on price without knowing the order originator.
• Anonymity and Efficiency
By design, the protocol delivers full confidentiality (no identities or sides revealed) and replaces time-consuming voice bargaining with an instant electronic workflow. MatrixCross emphasizes "anonymity: liquidity seekers never disclose identity or trade side" and "efficiency: electronic workflow eliminates delays"2. The patent claims cover these mechanisms as novel solutions to longstanding market frictions.
Because these innovations are patented and non-obvious, any copycat attempts by rivals would infringe the IP. The patent (granted Dec 2024) shields the core idea of splitting and obfuscating order data4. MatrixCross's early mover status and patent portfolio thus create a strong competitive barrier.
Competitive Context and Moat
All-to-All Momentum
The industry is already moving toward more all-to-all trading. Industry sources report that all-to-all corporate bond trading rose from ~5% of volume in 2017 to 12% in 20206, led by MarketAxess, Tradeweb and newer entrants (ICE, Trumid, etc.). Tradeweb's 2017 launch of "Blast All-to-All" enabled RFMs to a wide network, and its block activity grew to ~24% of trades7. Regulators and economists (e.g. the New York Fed) note that all-to-all platforms increase competition and lower costs for liquidity takers8. In this environment, having a proprietary all-to-all block solution is a major advantage.
Patented Differentiation
MatrixCross's IP – anonymous, threshold-based negotiation – is not offered by any current platform. Given the strategic shift to screen trading for blocks5, this legal protection ensures that MatrixCross and its partner will set the terms of engagement.
Next Steps – Call to Action
MatrixCross invites an exploratory discussion to tailor a collaboration with interested partners. We recommend initiating a technical review or proof-of-concept to demonstrate the protocol within your workflow environment. MatrixCross can provide a demo of its platform and explore any arrangement designed to enhance the value of any prospective partnership.
For further engagement, please contact MatrixCross at your earliest convenience to schedule a meeting or demonstration. Our team is prepared to outline integration options and support due-diligence.
