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.

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.

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.

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.

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.
