Ireland and Luxembourg hold almost exactly the same amount of UCITS money run by outside managers: $140.6 billion in Ireland and $139.6 billion in Luxembourg. The two markets work very differently, though. Ireland is a handful of very large buyers led by Mediolanum. Luxembourg is a long list of private banks, wealth managers and host ManCos, with 1,482 seats against Ireland's 554.
Key Takeaways
- Sub-advised assets are split almost evenly: $140.6 billion in Irish UCITS and $139.6 billion in Luxembourg UCITS (Dakota analysis of CBI and CSSF registers and funds' published annual reports, September 2026).
- Ireland is concentrated: the five largest platforms hold 86% of Irish assets with outside managers, and Mediolanum alone holds 53%. In Luxembourg the top five hold 48%.
- Luxembourg has 2.7 times as many seats (1,482 vs 554) and 7 times as many umbrellas with outside managers (299 vs 42).
- US-based managers hold 32% of Irish seats where the location is stated, against 9% in Luxembourg, where UK, Swiss and German managers lead.
- Oversight roles differ: Luxembourg filings name 225 conducting officers, while Irish ManCos oversee delegates through designated persons under the Central Bank of Ireland's six managerial functions.
How do Ireland and Luxembourg compare for UCITS sub-advisory?
Ireland and Luxembourg hold almost equal UCITS assets with outside managers: $140.6 billion and $139.6 billion. The difference is in structure. Ireland has 554 seats at 42 umbrellas, 13.2 per umbrella. Luxembourg has 1,482 seats at 299 umbrellas, 5.0 per umbrella, so it has more buyers, each hiring for fewer seats.
A few terms first:
- UCITS is the EU framework for regulated, liquid funds sold across Europe and beyond under one passport.
- An umbrella fund is one legal fund containing many sub-funds.
- The management company (ManCo) is the regulated firm responsible for the umbrella.
- A sub-advisor, or delegated investment manager, is the outside firm the ManCo appoints to run a sub-fund. Each manager-on-sub-fund appointment is a seat.
- Irish UCITS are authorised by the Central Bank of Ireland (CBI), and Luxembourg UCITS by the Commission de Surveillance du Secteur Financier (CSSF).

How many UCITS umbrellas and sub-funds are on each register?
The CSSF register lists 1,502 Luxembourg UCITS umbrellas with 10,042 sub-funds. The Central Bank of Ireland lists 550 Irish umbrellas with 6,300 sub-funds. Luxembourg has almost three times as many umbrellas, but only 299 of them use an outside manager, against 42 in Ireland.
Most umbrellas in both countries are run entirely by the promoter's own investment team, or delegate only within the same group. Dakota's research reads each umbrella's audited statements and prospectus to find the ones that name an outside manager: 615 name their delegates in their filings, and 341 use at least one outside firm.
The legal wrappers differ too:
- Ireland: an Irish umbrella is typically an investment company (plc), an ICAV (Irish Collective Asset-management Vehicle), a unit trust or a common contractual fund.
- Luxembourg: a Luxembourg umbrella is typically a SICAV (an investment company with variable capital) or an FCP (a contractual fund managed by a ManCo).
For a sub-advisor, the wrapper matters less than who controls the ManCo.
Which platforms dominate Irish sub-advisory?
Five platforms hold 86% of Ireland's $140.6 billion with outside managers. Mediolanum alone holds $75.0 billion, 53% of the Irish total. Russell Investments ($14.9 billion), Architas ($11.8 billion), Fineco's FAM ($11.8 billion) and Pacific Asset Management ($7.7 billion) complete the top five.

Ireland's sub-advisory market is built around large, deliberate multi-manager ranges: Mediolanum's blended equity funds, Russell's multi-manager umbrellas and Architas's large single-manager mandates. Host ManCos still matter, since 55% of Irish seats sit in umbrellas run by third-party ManCos. Carne hosts Russell's umbrellas, and Waystone hosts Pacific's and a long list of boutique platforms.
The profiles and incumbents for each are in our Top 10 UCITS Sub-Advisory Platforms in Europe.
Which platforms dominate Luxembourg sub-advisory?
Luxembourg's five largest platforms hold 48% of its $139.6 billion with outside managers: Banca Generali's LUX IM ($15.8 billion), Lumyna ($14.2 billion), Lombard Odier's PrivilEdge ($12.8 billion), Intesa Sanpaolo's Fideuram and Eurizon ranges ($12.8 billion) and NEF ($11.7 billion). The other half is spread across nearly 100 platforms.

Behind the top five sits Luxembourg's long tail: 102 platforms and ManCos delegate to at least one outside manager. Many are private banks and wealth managers running a SICAV for their clients, each with a few seats. Host ManCos such as FundPartner Solutions, Universal-Investment, UBS's white-label business, Waystone, Carne and FundRock hold 41% of Luxembourg seats.
Italian groups use both hubs. Six of the ten largest selector platforms in Europe belong to Italian banking or insurance groups. Two of them (Mediolanum and FAM) use Irish umbrellas, and four (LUX IM, Lumyna, Fideuram and NEF) use Luxembourg ones. Fideuram's Luxembourg funds are run by its Dublin ManCo.
Which strategies does each domicile outsource?
Irish platforms outsource equities first: global equities is the largest category, with 146 of 554 seats. Luxembourg platforms outsource multi-asset first, with 436 of 1,482 seats. Luxembourg also holds most of the market's US fixed income seats (129), reflecting its many private-bank ranges.

That is partly who the buyers are. Irish multi-managers such as Mediolanum and Russell buy global and US equity specialists. Luxembourg's private-bank and wealth-manager ranges buy from managers closer to home.
How do Irish and Luxembourg rules on delegation differ?
Both follow the UCITS Directive: a ManCo may delegate portfolio management, but it keeps the liability. The oversight roles differ. Ireland requires designated persons for six managerial functions, including investment management. Luxembourg requires at least two conducting officers and three levels of delegate oversight under CSSF Circular 18/698.
Ireland. The Central Bank of Ireland's Fund Management Companies Guidance assigns six managerial functions to named designated persons: regulatory compliance, fund risk management, operational risk management, investment management, capital and financial management, and distribution. The designated person for investment management oversees delegates. The guidance expects regular meetings with them and on-site visits.
Luxembourg. CSSF Circular 18/698 requires every Luxembourg investment fund manager to have at least two conducting officers. Where portfolios managed exceed €1.5 billion, those two officers cannot hold conducting-officer roles at other fund managers. Delegates must pass initial due diligence and periodic, risk-based due diligence, and are subject to ongoing monitoring.
The difference shows up in the filings. Luxembourg statements name 225 conducting-officer roles, while Irish statements name only one, because Irish designated persons are not usually listed in fund reports. The people behind the decision are covered in Who Picks the Sub-Advisor?.
Independent directors are more visible in Ireland. Titles show them in 32% of recorded Irish board and ManCo seats against 18% in Luxembourg, a lower bound, since not every filing labels independence.
Where are managers being hired and replaced?
Luxembourg is busier. Its statements for 2025 and 2026 disclose 197 appointments and 231 terminations across 49 platforms, against 152 appointments and 96 terminations across 13 Irish platforms. In both domiciles, most terminations were fund closures, mergers or moves (58% in Ireland, 61% in Luxembourg), not performance firings.

The pattern matches the structure. Ireland's big multi-managers reshape their line-ups every half-year, so appointments outnumber terminations. Luxembourg's long tail closes and merges more sub-funds, while still adding new ones. Our analysis of UCITS hires and fires breaks these down by strategy.
What does the domicile split mean for fund managers?
Treat Ireland and Luxembourg as two different sales motions. In Ireland, five platforms hold 86% of assets, so a few deep relationships reach most of the money. In Luxembourg, 102 platforms and ManCos share $139.6 billion, so coverage and timing matter more than any single relationship.
- For US and global equity specialists, Ireland is the natural first market. Its multi-managers buy those strategies, and US-based managers already hold 32% of Irish seats where the location is stated.
- For multi-asset, fixed income and European specialists, Luxembourg's private-bank and wealth-manager ranges are the larger opportunity.
- For boutiques, host ManCos in both domiciles (55% of Irish seats and 41% of Luxembourg seats) show which promoters are running outside-managed ranges, and which ones could launch one.
Frequently Asked Questions
Which has more UCITS sub-advisory assets, Ireland or Luxembourg?
They are almost equal. Dakota counts $140.6 billion of Irish UCITS sub-fund assets run by outside managers and $139.6 billion in Luxembourg, with same-group delegation excluded (September 2026). Luxembourg has far more seats, 1,482 against Ireland's 554.
Is Luxembourg a bigger UCITS domicile than Ireland?
By number of funds, yes: the CSSF register lists 1,502 UCITS umbrellas with 10,042 sub-funds, against 550 umbrellas and 6,300 sub-funds on the Central Bank of Ireland register. For sub-advisory specifically, the assets run by outside managers are about the same in both.
What is the difference between an Irish ICAV and a Luxembourg SICAV?
Both are corporate fund vehicles that can hold many sub-funds under one umbrella. An ICAV is an Irish Collective Asset-management Vehicle authorised by the Central Bank of Ireland. A SICAV is a Luxembourg investment company with variable capital, supervised by the CSSF.
Who oversees sub-advisors in Irish and Luxembourg funds?
In Ireland, the ManCo's designated person for investment management oversees delegates, under the Central Bank of Ireland's Fund Management Companies Guidance. In Luxembourg, the ManCo's conducting officers oversee them, under CSSF Circular 18/698, which requires initial, periodic and ongoing due diligence.
Are US managers more common in Irish or Luxembourg funds?
Irish. Where the filings state the manager's location, US-based entities hold 32% of Irish seats against 9% in Luxembourg. Many US groups also contract through a UK or Irish entity, so their real presence in both markets is higher.
Why do Italian groups use Irish and Luxembourg funds?
Six of the ten largest selector platforms belong to Italian banking or insurance groups. Their cross-border UCITS ranges sit in Dublin (Mediolanum, FAM) or Luxembourg (LUX IM, Lumyna, Fideuram, NEF), and are distributed to their clients in Italy and beyond through the UCITS passport.
Does domicile change how a sub-advisor is selected?
Not fundamentally. In both domiciles the platform's investment team recommends a manager, and the ManCo approves the delegation and keeps responsibility for it. What changes is who carries the oversight: designated persons in Ireland, conducting officers in Luxembourg.
