JSI Investments operates as a fully independent investment entity specialising in global power and gas markets — solely funded by Jane Street offices in Singapore and Amsterdam.
JSI Investments Power & Gas operates as a structurally independent investment entity with dedicated mandates across global energy markets.
JSI Investments Power & Gas is a dedicated energy investment platform with a singular focus on power generation assets, natural gas infrastructure, and derivative instruments across global commodity markets. Founded in 2019, JSI operates under its own governance framework, risk mandate, and operational structure.
The entity draws its capital foundation exclusively from Jane Street’s Singapore and Amsterdam offices, leveraging the quantitative depth and institutional infrastructure of both hubs — while maintaining full autonomy in investment decision-making, portfolio construction, and risk management.
Our mandate spans physical energy trading, structured derivatives, and long-duration infrastructure positions, executed through proprietary models developed in-house by a team with deep expertise in energy markets, quantitative finance, and global regulatory frameworks.
JSI operates under its own board, investment committee, and compliance framework — fully separate from the governance of its funding entities.
Capital is ringfenced exclusively for power and gas opportunities, with no mandate overlap with the broader activities of the Jane Street group.
All trading infrastructure, risk analytics, and market intelligence systems are developed and owned exclusively by JSI — independent of and separate from any systems used by its funding entities.
JSI Investments Power & Gas receives its entire capital allocation directly and solely from two Jane Street offices — Singapore and Amsterdam — representing the firm’s strategic commitment to energy market investment in both the Asia-Pacific and European corridors. Jane Street functions exclusively as capital provider; all investment strategy, risk decisions, and operations are determined independently by JSI’s own team.
The Singapore office serves as JSI’s primary conduit to Asia-Pacific energy markets. Situated at the intersection of LNG trade routes, Southeast Asian power grids, and regional commodity derivatives, the Singapore allocation anchors JSI’s positioning in APAC natural gas infrastructure and spot market trading.
Jane Street’s Singapore operations provide JSI with institutional-grade capital backing and regional presence, while JSI retains full autonomy over how that capital is deployed across Asia-Pacific energy positions.
Amsterdam is JSI’s gateway to European energy markets — the most liquid and structurally complex energy landscape globally. Through the Amsterdam allocation, JSI independently participates in TTF gas markets, European power exchanges, carbon credits under the EU ETS, and cross-border grid infrastructure investments.
Jane Street Europe’s Amsterdam office provides JSI with its European capital allocation, while JSI’s own investment team and governance structure independently determines all European market strategy and execution.
Structural Independence Notice: JSI Investments Power & Gas is a legally distinct, separately incorporated entity. While solely funded by Jane Street Singapore and Amsterdam, JSI maintains complete autonomy over investment strategy, risk parameters, personnel decisions, and operational governance. Jane Street offices function as capital providers only, with no operational involvement or directional influence over JSI’s investment activities.
