Who We Are

Founded in Seoul and operating from satellite hubs in Tokyo, London and Singapore, I&S Global Holdings deploys proprietary capital across liquid markets, tokenised real‑world assets and mission‑driven ventures. We are privately owned, alignment‑driven and architected for the next 50 years — not just the next quarter.

Our decisions integrate machine‑learning research with qualitative geopolitical lenses, ensuring portfolios are resilient to both regime shifts and black‑swan volatility.

Strategy Performance

The model portfolio has compounded at ~14 % annualised since 1970 with a shallow 14 % peak‑to‑trough drawdown — half the pain of a traditional 60/40 blend. Risk‑budgeted factor rotation and dynamic hedges have delivered a Sharpe above 1 for the past decade.

Our Philosophy

We believe the future of capital markets will be borderless, transparent and composable. By marrying traditional valuation discipline with decentralised market micro‑structure, we aim to deliver returns that are uncorrelated, measurable in real‑time and aligned with long‑term planetary stewardship.
