Prosperity is a coordination game. When the pie grows, rivals trade. When it stalls, they raid. That shift, from exchange to extraction, explains the rise of anti-system, anti-growth parties on both left and right. It also explains why markets keep mispricing political risk. We are not in a normal cycle. We are in a regime shift where incentives to cooperate decay, buffers thin, and minor shocks propagate like cracks in tempered glass.
For four decades, politics in advanced economies ran on a conveyor belt of rising productivity, liberalized trade, and cheap energy. That belt is now jammed. The productivity slowdown predates the pandemic. Demographics add drag. Public debt is high, and real rates are no longer free. Basic inputs are costlier and slower to build. When growth underwhelms, rents dominate. Voters and firms fight to protect their slice rather than expand the pie. It is the classic move from positive-sum to zero-sum. The center loses narrative power because it cannot promise credible future surplus. Outsiders win by promising to defy math.
Game theory tells us repeated games need patience and surplus to sustain cooperation. Lower growth reduces the discount factor. Players defect earlier. In policy, defection looks like tariff wars, export controls, windfall taxes, price caps, and targeted subsidies that penalize outsiders. Each measure may poll well. Together they harden borders and raise costs. The political narrative becomes one of entitlement to existing income streams. Regulators are pushed to harvest quasi-rents from sectors seen as fat with profits. Institutional constraints that once slowed raids on capital and labor get tested and weakened. The norm becomes grabbing what you can, now, because later is uncertain.
Investors often treat political risk as idiosyncratic and diversifiable. That assumption breaks when the same zero-sum logic drives multiple jurisdictions. Correlation rises. A subsidy in one place forces retaliation elsewhere. A ban in one sector shifts cash flows across the whole supply chain. Volatility clusters as narratives pile up. Crowds on trading apps anchor on price patterns and chase the same exits. Feedback loops form. Liquidity looks deep until many need it at once. The 2008 playbook—hope the central bank floods the zone—assumes a single shock and a single rescuer. In a zero-sum regime, policy itself becomes the correlated shock.
The post-2008 era taught markets to expect an unprecedented amount of money to appear on demand. That habit met inflation. Central banks now face a hard constraint: rescue too much, and you feed prices or currencies; rescue too little, and balance sheets break. Fiscal authorities, meanwhile, are highly levered to growth that is not materializing. This is fiscal dominance in slow motion: monetary policy bends to funding needs. The risk is policy whiplash—tight, then loose, then tight—each swing redistributing wealth and faith in institutions. Fragility grows when buffers are spent on optics instead of optionality.
Two sectors turn zero-sum politics into systemic risk: energy and housing. Energy policy is caught between physics and promises. Permitting uncertainty and subsidy churn turn long-cycle projects into political assets. Underinvestment yields spiky prices that become election issues. Housing is worse. Decades of zoning scarcity created a lottery. Rising rates exposed leverage and the dream of ever-cheaper mortgages. Any attempt to reprice land or permit density is cast as assault or bailout. These are slow-burn risks with fast-break moments. When they move, they move entire tax bases, bank books, and voter blocs.
Zero-sum politics elevates executive action and emergency measures. That concentrates power and reduces transparency. Off-balance-sheet guarantees multiply. Quasi-fiscal vehicles—the alphabet soup of facilities and funds—blur who bears risk. Data quality degrades as incentives to show stability increase. Markets, deprived of clean signals, react to headlines and rumors. Index investors become accidental activists as politics infiltrates corporate governance. The legal line between policy and property weakens as states test expropriation-lite moves. Confidence, an asset without a line item, becomes the scarcest good.
Behavior matters. In a zero-sum frame, the brain spots threats faster than opportunities. Loss aversion, status anxiety, and narrative contagion drive synchronized behavior. Retail crowds learn the same playbooks and rush the same exits. Institutions perform the same factor trades and hedges. Those overlaps turn ordinary drawdowns into cascades. Speed compounds the problem. Information travels in seconds, but due diligence still takes days. The gap is where mistakes live. The more we optimize for efficiency, the less room we leave for error. Thin margins meet thick tails.
The answer is not to predict which faction wins the next policy raid. Prediction looks smart until it doesn’t. The answer is structural. Systems that survive hostile games share traits: redundancy, slack, and simple rules. They avoid single points of failure. They hold cash when cash is hated. They depend less on legal favors and more on unit economics. They can absorb energy and rate shocks without begging for rescue. For policymakers, the boring path is the only durable one: clear rules, fast permitting, tradable certainty, housing supply, skilled immigration, tax simplicity. These are not slogans. They are the plumbing that turns zero-sum back into positive-sum.
A stalled conveyor belt breeds factions that promise to win by taking. That is a political problem before it is a market problem, and a market problem before it is a portfolio problem. The longer we ignore the regime shift, the more we entrust our savings and institutions to brittle assumptions. In nature and in finance, systems that cannot bend will eventually break. The contrarian position now is not cynicism. It is building buffers while others trade them away.
