In Episode 436 of Hidden Forces, Demetri Kofinas speaks with economist, policy adviser, and investor Sony Kapoor about why developed world demographics, debt, and political sclerosis will crush forward returns for investors who fail to rebalance their portfolios for the new investment paradigm.

Kapoor and Kofinas spend the first hour of their conversation unpacking the thesis explored by Sony in two of his papers: “Winter Is Coming” and “The Case for a Great Rebalancing” in which he argues that global capital has been increasingly misallocated due to factors such as the growth of passive indexation, maladaptive benchmarking, and an excessive focus on short-term performance at the expense of long-term returns.

They explore how demographic tailwinds in advanced economies have flipped into headwinds; whether AI driven productivity gains can realistically offset the drag of declining birth rates; why accommodative post GFC monetary and fiscal policies undermined political stability in developed countries; and what recent stresses—including dollar weakness, Treasury market liquidity scares, and an increased reliance on short-term debt financing—suggest about looming financial repression, fiscal dominance, and a rotation out of U.S. capital markets.

The second hour is devoted to a conversation about investor incentives, market structure, investment opportunities in emerging markets, and how to construct a more diversified portfolio suitable for the world that is coming into being. Demetri and Sony discuss why political and currency risks may now be lower for a diversified emerging markets basket than for a similarly diversified portfolio of developed market assets. They discuss what a reweighting toward emerging markets could look like; why India stands out given its digital public rails and domestic-demand engine; how places like Indonesia, Brazil, and Nigeria fit into a rebalancing; and how to think about geopolitics, US policy risk, and portfolio construction in this new paradigm.
