Will the addition of Mizuho as a clearing member increase ICE Clear Credit’s market share against competitors like CME and LCH?

Short answer:

Yes, the addition of Mizuho Americas (via Mizu Capital Markets) as a clearing member is likely to bolster ICE Clear Credit’s market‑share trajectory, especially against its two main rivals—CME Group’s clearing platform and LCH (UK) Ltd. The impact will be indirect (through higher cleared volumes, broader product reach and enhanced credibility) rather than an immediate “instant‑gain” in market‑share percentages, but the move positions ICE Clear Credit to capture a larger slice of the growing CDS‑clearing market over the medium term.

1. Why a new clearing member matters

Factor	How Mizuho’s membership influences ICE Clear Credit
Liquidity & Trade Flow	Mizuho Americas is a major security‑based swap dealer with a sizable client base (institutional investors, hedge‑funds, corporate treasuries). When it routes its CDS trades through ICE Clear Credit, the daily cleared volume on the platform rises. More volume improves net‑ting efficiency, reduces margin requirements for all participants, and makes the platform more attractive to other dealers who seek the deepest pool of counterparties.
Product Breadth	Mizuho’s “security‑based swap” franchise includes a range of credit‑default‑swap (CDS) and related credit‑derivative products. By clearing these through ICE Clear Credit, the platform can expand its product catalogue (e.g., sovereign, corporate, and structured‑credit CDS). A richer offering draws additional market participants who might otherwise stay on CME or LCH.
Credibility & Counter‑party Confidence	Mizuho is a globally recognised, well‑capitalised financial group (NYSE: MFG). Its decision to clear with ICE Clear Credit signals confidence in the clearinghouse’s risk‑management framework, operational resilience, and capital‑efficiency. This endorsement can persuade other high‑credit‑rating dealers to follow suit, a classic “network‑effect” driver of market‑share growth.
Capital‑Efficiency for Mizuho	The news notes that Mizuho is “excited … to enhance our product offering and approach to capital.” By using ICE Clear Credit’s margin‑optimised clearing model, Mizuho can lower its own capital charge on cleared CDS positions. The more capital‑efficient a clearinghouse is perceived to be, the more likely other capital‑intensive dealers will gravitate toward it.

2. Competitive landscape: ICE Clear Credit vs. CME vs. LCH

Platform	Core strengths (as of 2025)	Key challenges
ICE Clear Credit	• Largest dedicated CDS clearinghouse in the U.S. • Advanced margin‑ing and net‑ting algorithms • Strong integration with ICE’s data and execution venues (ICE Futures, ICE Bonds)	• Still expanding global reach (cross‑border clearing) • Competition from CME’s “Credit” clearing product and LCH’s “Clearstream” services
CME Group	• Deep futures & options ecosystem, strong US‑based clearing capacity • Aggressive pricing for high‑volume dealers	• Historically less focused on pure CDS clearing; its credit‑derivative clearing is newer and less entrenched than ICE’s
LCH (UK) Ltd	• Global clearing footprint, especially in Europe and Asia • Established “LCH.Clearnet” for credit‑default swaps (via LCH.Clearnet’s “CDX” clearing)	• Higher regulatory capital buffers for non‑U.S. participants can raise cost for U.S. dealers • Perceived as “European‑centric” for some U.S. market‑makers

Resulting dynamics:

- Depth of clearing pool is a primary driver of market‑share. Adding a heavyweight dealer like Mizuho expands ICE Clear Credit’s pool, giving it a quantitative edge over CME and LCH.

- Product coverage matters. If Mizuho brings new structured‑credit or sovereign CDS products that ICE Clear Credit can clear, the platform differentiates itself from CME’s more futures‑centric suite and from LCH’s European‑focused offerings.

- Capital‑efficiency perception is a competitive lever. Mizuho’s public statement about “enhancing our approach to capital” suggests ICE Clear Credit’s margin model is attractive; this can lure other capital‑constrained dealers away from CME/LCH.

3. Expected trajectory of market‑share impact

Time horizon	What to expect
0‑6 months	Immediate uptick in cleared CDS volume from Mizuho’s existing book. No dramatic shift in market‑share percentages, but ICE Clear Credit’s daily volume metric will rise, improving its “liquidity depth” ranking in industry reports.
6‑24 months	As Mizuho’s clients (and possibly its subsidiaries) migrate to the ICE Clear Credit platform, the clearinghouse can attract secondary dealers, hedge‑funds, and corporates that value the larger net‑ting pool. Competitors may respond with pricing cuts or product launches, but ICE Clear Credit will have cemented a broader client base.
2‑5 years	If the partnership spurs further onboarding of other major dealers (e.g., Goldman Sachs, JP Morgan) who view ICE Clear Credit as the “go‑to” CDS clearing hub, ICE Clear Credit could capture a double‑digit market‑share advantage in the U.S. CDS clearing market, edging out CME’s nascent credit‑clearing offering and narrowing the gap with LCH’s global footprint.

4. Potential limits & counter‑points

Regulatory fragmentation – If regulators in Europe or Asia favour LCH for cross‑border CDS clearing, Mizuho’s U.S.‑centric clearing may not translate into global market‑share gains.
Pricing competition – CME could lower clearing fees or bundle CDS clearing with its dominant futures platform, which might blunt the volume‑gain effect.
Technology parity – If ICE Clear Credit’s technology does not keep pace with CME’s or LCH’s enhancements (e.g., real‑time margining, blockchain‑based proof of clearing), participants might still prefer the more advanced platform despite Mizuho’s presence.
Mizuho’s own clearing strategy – Mizuho could keep a portion of its CDS trades on other clearing houses for diversification, limiting the net impact on ICE Clear Credit’s volume.

5. Bottom line

Yes, the addition of Mizuho Americas is a positive catalyst for ICE Clear Credit’s market‑share growth against CME and LCH.
The effect will be incremental but cumulative: higher cleared volumes, richer product set, and stronger credibility will attract more participants over the next 1‑3 years.
Competitive response from CME and LCH will shape the ultimate magnitude, but ICE Clear Credit is now better positioned to claim the role of the primary U.S. CDS clearing hub, which historically translates into a larger share of the overall credit‑derivatives clearing market.

In short, while the move alone won’t instantly double ICE Clear Credit’s market‑share, it materially strengthens the platform’s growth engine and should enable it to out‑pace its rivals in the medium‑term, assuming it continues to invest in technology, product breadth, and capital‑efficiency.
