Macquarie Korea Infrastructure Fund (MKIF) was established in December 2002 as a joint venture between Macquarie Group and Shinhan Financial Group, listing on the KOSPI in 2006 and now serving approximately 210,000 investors with a market capitalization of KRW 5.3 trillion.
Rather than directly operating infrastructure assets, MKIF invests in 19–20 individual special purpose companies (SPCs) through a combination of equity stakes and subordinated/senior loans, earning dividend and interest income in return.
As of 2025, the portfolio is approximately 69% subordinated loans, 30% equity, and 1% senior loans, making interest income the primary revenue driver.
Toll roads, bridges, and tunnels remain the core earnings contributors, with Green Digital Infrastructure/Hanam IDC (~10.4%), Incheon Bridge (~10.3%), and Cheonan-Nonsan Expressway (~8.0%) among the leading holdings.
The portfolio comprises 15 concession-based infrastructure projects with fixed operational terms and 4 perpetual businesses, including three city gas utilities (CNC City Energy, Hayang Energy, Serabol City Gas).
In 2024, MKIF made its inaugural digital infrastructure investment by acquiring the Hanam hyperscale data center (40MW, KRW 423bn total commitment), broadening the fund's scope beyond physical transportation and energy infrastructure.
Additional new assets—including the Dongbu Expressway underground project (KRW 214bn), Dongbuk Line urban railway, Incheon-Gimpo Expressway, and Busan New Port Second Access Road—are expanding the fund's future cash flow runway.
Under the Private Participation in Infrastructure Act, borrowing is capped at 30% of equity capital; as of March 2025, the fund had utilized KRW 446.6bn of its KRW 989.2bn borrowing limit, maintaining an equity ratio of 88.1%.
MKIF's dominant position in Korea's private infrastructure market, underpinned by over two decades of operational track record and an investor base of approximately 210,000, confers a meaningful competitive moat over any emerging rival funds.
