Being Country Head, Ireland, of Northern Trust is to lead a focused business but one that supports a diverse range of clients with varying requirements. Northern Trust, founded in 1889, specialises in providing asset management, asset servicing and wealth management services to corporations, institutions, affluent families, and individuals. It has global assets under custody/administration of US$16.9 trillion, as well as assets under management of US$1.6 trillion. Its business in Ireland specialises in asset servicing and employs close to 1,800 staff, 1,400 of them based in Limerick with the balance in Dublin.

Meliosa O'Caoimh: "across our industry's funds ecosystem, we must all remain nimble and flexible in response to emerging opportunities, which could include the EU's capital markets union initiative and desire to promote retail investment across Europe".
2025 marks the quarter century anniversary of Northern Trust establishing its presence in Ireland, a landmark she is keen to emphasise. This began with the acquisition of Ulster Bank Investment Services which had funds under administration of €9.4 billion, according to that year’s Finance Dublin Yearbook. Today the value of funds Northern Trust administers in Ireland have grown to over €630 billion,

A strategic location
At the heart of that becoming a leading asset servicing business in Ireland are strategic decisions made decades before and a focus on clients. “We established ourselves here to help our clients take advantage of European fund opportunities,” says O’Caoimh. “We have serviced Irish clients since 1989 from outside Ireland, but since then, our business has grown in line with industry complexity, and the requirements of our clients.
“We set-up our Dublin office in 2000 and then expanded into Limerick in 2007. Our milestones since have included taking part in landmark Irish funds industry developments such as servicing the first major European exchange traded funds (ETFs) launched in 2000 and being part of the team that launched Ireland’s first tax-transparent solution for multinationals.”

Today the value of funds Northern Trust administers in Ireland have grown to over EUR €630 billion.
Today Northern Trust in Ireland is a strategic location within its global asset servicing business, she says: “We support global investors’ use of Irish funds – from the most traditional to the most complex – and help them achieve their business priorities, whether to grow scale and resiliency or to modernize their operations. We service clients from all over the world including investment managers, pension funds, multi-nationals, insurance companies and not-for-profit organizations.”
O’Caoimh also cites Northern Trust’s choice of Limerick as a European servicing hub alongside its presence in Dublin as a key milestone in its Ireland growth story. “The range of services we provide from Limerick have extended over time and it has become one of our strategic global servicing locations. It complements our teams in Asia and North America, helping seamlessly provide coverage for their investments around–the–clock while ties to Limerick’s higher educational institutions provide access to talent and career opportunities for newer entrants to the workforce.”
“I was part of the management group that chose Limerick as the location of our European funds servicing centre, and it has proven to be a fabulous location for us – the quality of the people, the infrastructure, the University, everything – has worked out very well.
The height of our original ambitions was that our offices there would have 300 employees in it, but far more colleagues support our clients from Limerick today,” she says.
Technology is central to the evolution of financial services and here too, Limerick has come to the fore, says O’Caoimh. “Through our Limerick–based Innovation Laboratory, which was established in 2018, our Ireland operations have similarly grown to play a significant role in the development of our data platform and the use of digital technology to facilitate enhanced functionality, speed, and insight for our clients”.
“Experts based in our Lab help staff adopt new technologies and work with them to harness the power of FinTech across our business. We are using robotics, machine learning and other technologies to improve efficiency and help our employees to move up the value chain. We remove the jobs that are repetitive in nature where we can and try to provide people with time to focus on the value they can bring to their roles.”
International success story
Asked for her view on the outlook for the future of Ireland’s funds industry, she is optimistic, while acknowledging that headwinds from volatility across public markets mean that the global economic outlook remains uncertain. Significant risks remain unresolved, she says - (the interview took place on May 9th) “not least those pending the prospects for trade negotiations and other related developments”.
Her optimism, she says, reflects the success of the investment funds industry in Ireland, which in 30 years has grown from inception to its position today as one of the world’s foremost hubs for investment funds: “Many of our clients are asset managers from all over the world who are devising ideas and strategies about how they might invest clients’ funds. And then they put them into structures in Ireland, like UCITS funds, which are in turn distributed around the world”.
Whatever investment strategy or fund product that a client may approach us for help in supporting or launching – from simple to complex strategies and from traditional listed funds to funds of funds, liability-driven investments, real estate, private equity, and infrastructure funds – we can service it all out of Ireland.
“These funds and their investors are supported by Ireland’s robust and professional legal and regulatory framework that has been developed over the past 30 years, and which continues to evolve in response to challenges and opportunities. This is an international success story.”
Flows and future opportunity
From Northern Trust’s position as asset servicer to investment funds, where does O’Caoimh see opportunities emerging and assets flowing? “Our clients continue to evolve their offerings for investors, and there is no doubt that currently the two most significant growth areas are ETFs and private markets investing such as private credit, real estate and infrastructure,” she says.
“But whatever investment strategy or fund product that a client may approach us for help in supporting or launching – from simple to complex strategies and from traditional listed funds to funds of funds, liability-driven investments, real estate, private equity, and infrastructure funds – we can service it all out of Ireland.”
Asked what factors will be important for further sustained growth for the industry in Ireland, she cites its capabilities to support innovations such as the tokenisation of funds and growing its reputation as a natural home for private markets strategies.
“Across our industry’s funds ecosystem, we must all remain nimble and flexible in response to emerging opportunities, which could include the EU’s capital markets union initiative and desire to promote retail investment across Europe. Our objective should be to ensure Ireland continues to have the requisite competitive first-mover advantage and capabilities to retain existing market share and support further growth”, she adds.
“Ireland has blazed that innovative trail several times, perhaps most notably around exchange traded funds,” she says.
“When ETFs were launched, also 25 years ago – Ireland was well-positioned to help investors realise their potential. The whole financial ecosystem including lawyers, accountants, fund administrators – collectively we capitalised on the ETF opportunity and ensured that Ireland was ready to support this emerging market.” Ireland is now the biggest jurisdiction for ETF administration, with around 70% of European ETFs being now serviced out of Ireland according to Irish Funds

A relationship business
She says that despite advances in technology and fund innovation however, the funds industry ultimately remains a people-centric business to which knowledge, experience and relationships remain fundamentally important. “One of the most rewarding aspects of my role at Northern Trust is to be part of a network that is supportive of colleagues’ life-long development, and to see them accumulate knowledge and experience at first-hand,” she says.
The range of services we provide from Limerick have extended over time and it has become one of our strategic global servicing locations. It complements our teams in Asia and North America, helping seamlessly provide coverage for their investments around the clock.
“People are at the heart of everything we do – we are, after all, a relationship business, one that is focused on client service. And our offices here are staffed by a combination of people: some have decades of industry experience gained in Ireland while many have joined us directly from local schools and colleges. Additionally, we have attracted Irish colleagues who have returned home from abroad to work with us, along with colleagues who have joined – and stayed – through the business acquisitions we have made.”
“Our success over 25 years is their success in delivering consistent client service and innovation for our clients and their investors.”
While the funds industry remains a people-centric business she says that technology and innovation offer new possibilities.
“One of the most rewarding aspects of my role is to be part of a network that is supportive of colleagues’ development, and to see them accumulate knowledge and experience,” she says. In our era of technological advancement, that industry knowledge – coupled with the combination of great people and new technologies – will open-up new possibilities for us and our industry in how we can support clients, service their investors, and grow future market share.”
