The initiative, announced during the state visit and co-chaired by finance ministries with regulators involved, is framed to remove cross-border frictions in capital markets and digital assets, with recommendations expected around March 2026.
The U.S. generic listing standard sets repeatable eligibility, surveillance sharing, and disclosure patterns. The task force can map those patterns into a cross-listing pathway for London that recognizes outcomes rather than duplicating the process.
The U.S. rule change reduces the interval between filing and the first trade to a fixed window, which has been one of the primary gating items for new single-asset and basket products.
If London accepts the U.S. package as equivalent for secondary listings, exchanges can carry over diligence and market surveillance agreements, then scale local documentation to UK rules.
UK capital-raising reforms that raise thresholds for follow-on offerings and streamline prospectuses provide the other half of the plumbing due to shorter documentation windows and a new public offers platform that will be phased in through 2026.
A market structure test case already exists in London.
This venue can import price discovery from the United States once a matching product trades on a U.S. exchange under the generic standard. The U.S. spot bitcoin ETF experience shows how spreads respond when multiple market makers compete and depth consolidates.
Cboe analysis of post-launch trading shows a compression in national best bid and offer spreads in the early sessions, moving into low basis point territory as assets and quoting interest scale. Those mechanics translate to London if order flow and hedging inventory are portable across venues and if settlement and custody risks are standardized.
The practical output of a six-month playbook is a short stack of documents that firms can use immediately.
One is a recognition note that connects the SEC generic listing criteria and surveillance sharing to UK listing requirements for secondary lines. Another is a custody sub-delegation FAQ that describes wallet operations, cold and hot key segregation, and assurance reporting across jurisdictions.
A third is a model disclosure annex covering forks, airdrops, staking treatment where applicable, valuation agents, and corporate actions.
Together, these items cut time to list for a UK secondary line toward the U.S. 75-day mark, where the originating product already meets generic criteria, while avoiding a second round of first-principles review.
Over the next two quarters, a base case assumes those soft law tools rather than wholesale statute changes.
In that case, U.S. venues continue to expand the roster under the generic rule, with single asset trackers such as Solana and XRP likely among early candidates.
London can then mirror top U.S. lines, add multi-asset baskets, and rely on arbitrage to connect quotes.
Under that setup, London Bitcoin and crypto ETN average daily volume increases in the mid double-digit range from present levels, and quoted spreads compress by roughly one-fifth to one-half compared with the summer baseline, drawing on the depth and maker competition seen in the United States and on the larger European turnover that built through 2024.
The issuance mix shifts as U.S. brands pursue secondary lines and as existing European issuers extend families to keep index coherence across venues.
If regulators publish a template that treats a defined U.S. crypto ETP disclosure pack as outcomes equivalent for UK purposes, the number of London lines could rise into the high teens or low thirties within the window, with bank market makers onboarding once custody sub-delegation is explicit.
In that case, custody fees move lower for large mandates as bank providers bring balance sheet and control frameworks, and creation or redemption cutoffs move earlier in the session.
The bear case limits output to principle-only statements, which preserves current frictions, keeps London count near present levels, and leaves the most widespread improvement to organic maker competition.
Capital raising sits alongside listings and custody. The UK reform track raises follow-on thresholds, trims prospectus periods, and introduces a platform model for public offers.
That design can be paired with U.S. shelf mechanics so Bitcoin, crypto infrastructure, and fintech issuers can run parallel books rather than sequence markets. A precedent exists in North American cross-border offerings that use mutual recognition of disclosure, documented in U.S. and Canadian materials for the multijurisdictional disclosure system.
Applying that pattern to digital asset ETP documentation and operating company raises would reduce duplicative drafting and enable simultaneous marketing windows without creating a separate bespoke carve-out.
First, watch for a dual listing fast path in the interim report around day 90 that outlines how exchanges can port surveillance and eligibility packages.
Second, look for custody sub-delegation language referencing both OCC letters and UK custody consultation outcomes, with explicit wallet control and attestation mapping.
Third, track a model disclosure annex that issuers can staple to both U.S. and UK filings.
Fourth, connect UK capital raising thresholds to U.S. shelf capacity in a way that lets issuers synchronize calendars.
The final metrics to monitor are LSE line count, average spreads, and daily volumes, collateralized by maker rosters and custody provider names.
Flows and positioning can move earlier than formal recommendations, so the pipeline may adjust before the 180-day mark. CoinShares shows sustained inflows into digital asset funds through late summer, with the United States in the lead, which supports inventory for creations once new tickers are listed.
If U.S. exchanges continue to open new spot lines under the generic rule and if London recognizes that diligence, the transfer of price discovery will show up in London quotes within the quarter through standard cross-venue arbitrage channels.
The primary risk to the timeline is supervisory bandwidth rather than a need for new law, since most of the required actions involve recognition notes, FAQs, and shared templates rather than statutory rewrites.
The task force described the six-month window as a target for recommendations, and the calendar now runs.
