CSH Investment Management
CSH Investment Management is the London family office of Lord Michael Spencer, built on the ICAP and NEX Group interdealer brokerage fortune.
CSH Investment Management
The single-family office was established to steward the wealth Lord Michael Spencer generated as the founder and former CEO of ICAP, the world's largest interdealer broker at its peak. ICAP matched trades in government bonds, swaps, and foreign exchange for banks globally, producing steady, transaction-based cash flows before its sale of voice-broking assets to Tullett Prebon in 2016. Spencer walked away with a significant stake in the enlarged TP ICAP group, forming a durable liquidity anchor for his family office. CSH Investment Management invests across three primary pillars: direct private equity, commercial real estate, and credit opportunities. The office has a pronounced focus on founder-led businesses and financial services technology, a natural overlap with Spencer's career building market infrastructure. Confirmed investments include equity stakes in NEX Group, the electronic trading platform that Spencer spun out of ICAP and later sold to CME Group for approximately £3.9 billion (per the firm's official communications, 2018), as well as positions in real assets across London prime commercial property. The office pursues both direct co-investment and small consortium club deals where Spencer can provide operational mentorship alongside capital. Headquartered in London, the office maintains a deliberately lean profile, with investment decisions flowing through Spencer himself and a tight advisory group. While the exact AUM remains undisclosed, the structural exit of NEX Group in 2018 alone crystallized proceeds widely reported as exceeding £1.5 billion, positioning the family among the UK's substantial private investment pools (per Financial Times, 2018). In November 2018, Spencer completed the sale of NEX Group to CME Group in a landmark exchange-infrastructure transaction, directly restructuring the family's liquid net-worth composition. CSH Investment Management stands apart through its operator-centric origin. Unlike the diversified multi-asset orthodoxy common among European family offices, the firm maintains concentrated, high-conviction positions in sectors where Spencer personally held executive accountability. This creates a governance dynamic where the principal retains direct influence over portfolio-company strategy, a posture that mirrors the single-decision-maker architectures of some US family offices rather than the institutionally tiered committees prevalent in London.

Frequently asked questions
Who runs investment decisions at CSH Investment Management?
Lord Michael Spencer acts as the primary investment principal. Spencer founded ICAP in 1986 and led it for over three decades, retaining direct influence over the family office's portfolio construction. The office operates with a small advisory team rather than a delegated investment committee structure.
Where does the underlying wealth come from?
The wealth originates from Lord Spencer's founding and leadership of ICAP, the global interdealer broker that handled high volumes of fixed-income and foreign-exchange trades between major banks. The sale of NEX Group, the electronic markets and post-trade business he spun out of ICAP, to CME Group for £3.9 billion in 2018 significantly crystallized family liquidity.
Does CSH Investment Management commit to external funds or only direct deals?
The office primarily executes direct deals and club-style co-investments, often alongside other founders and operators. There is no publicly available evidence of a fund-of-funds allocation program. The structure appears deliberately oriented toward concentrated, high-conviction equity positions where Spencer's operating experience has direct application.
What is CSH Investment Management's geographic investment focus?
The office invests predominantly in the United Kingdom, particularly in London, where both Spencer's business network and commercial real estate holdings are concentrated. Cross-border exposure is limited to specific operating-business stakes with existing UK connections.
Does Lord Spencer maintain philanthropic structures, and how are they separated?
Lord Spencer supports charitable causes, including medical research and education, but the family's philanthropic activities are generally conducted through personal giving and charitable trusts that remain operationally distinct from the investment office. The separation mirrors the architecture of many London-based family offices that keep investing and grant-making functions segregated.
