Core Viewpoint - The article discusses the cyclical nature of commodity markets, emphasizing the importance of macroeconomic factors such as the dollar cycle, global economic growth quality, and policy changes in major economies, while analyzing historical trends and their implications for future commodity pricing [4][5][6]. Group 1: Historical Context of Commodity Cycles - Different eras have distinct dominant factors influencing commodity prices, with a review structured around significant events and changes in the global landscape [7]. - The 1970s marked a unique period of stagflation, initiated by the collapse of the Bretton Woods system, leading to a decoupling of the dollar from gold, resulting in a chaotic economic environment where commodity prices surged despite economic recession [11][12]. - The 1980s saw a recovery with the stabilization of the dollar and economic growth in the U.S., where commodity prices were positively correlated with GDP, particularly during the period of the Plaza Accord [15][16]. Group 2: Economic Growth and Commodity Prices - The relationship between commodity cycles and economic growth attributes is significant, with emerging economies and new growth drivers having a more substantial impact on commodity trends than inventory cycles [10]. - The early 2000s experienced a super bull market in commodities driven by China's industrialization and demand, with the CRB index rising from 200 to 480 before the financial crisis [21][23]. - Post-financial crisis, the period from 2008 to 2018 was characterized by China's stimulus measures, which temporarily boosted commodity prices, but ultimately led to overcapacity and a prolonged bear market [28][32]. Group 3: Current and Future Trends - The era of de-globalization, marked by U.S.-China tensions and the COVID-19 pandemic, has reinforced the monetary attributes of commodities, leading to a recent bull market in the CRB index [35][38]. - The relationship between the CRB index and China's economic cycles has weakened, indicating a shift in the dynamics of commodity demand and pricing [39]. - The long-term price range of commodities is influenced by their monetary attributes and cyclical properties, with potential for the CRB index to rise to a new range of 500-700 due to ongoing monetary expansion [47].
