This article proposes the concept of the Saturation Law of Economic Fields as a structural framework for understanding asset price dynamics and recurring economic crises throughout human history. It argues that asset prices cannot rise indefinitely but are structurally constrained by the overall accessibility of society. When prices exceed the collective purchasing capacity of the majority, the economic field enters a state of structural saturation and must adjust through market correction, state intervention, social restructuring or political turbulence. Drawing upon Social Relativity Theory (SRT), the article conceptualizes the economy as a field of forces composed of resources, power and access. When the mass of prices accumulates beyond the system’s capacity to sustain them, the economic field becomes structurally distorted and approaches a saturation point comparable to a systemic speed limit beyond which further acceleration becomes unsustainable. The study examines temporal dimensions and accumulation phases preceding saturation through historical case studies, including the Dutch Tulip Mania, pre-revolutionary French bread inflation, Japan’s asset bubble, global gold cycles and China’s real estate expansion. It further suggests that high leverage and intensive speculation significantly shorten the time required for systems to reach saturation, particularly in the digital age where technological acceleration compresses economic cycles. The Saturation Law of Economic Fields provides a theoretical lens for analyzing asset bubbles, systemic adjustments and large-scale civilizational transitions in contemporary global economic structures.
