The pattern of the three commodity bull markets since 2008 has followed a cyclical rhythm of "gold and silver moving first → copper confirmation → oil explosion → agricultural closure". At this time, Maitong has launched the new Global Agriculture Full Industry Chain ETF and Agricultural Head ETF, and has seized the opportunity quite well. Here we can briefly discuss the core logic of the rotation rhythm of bulk commodities: 1) When economic uncertainty rises, or recession expectations intensify, and geopolitical games intensify, precious metals represented by gold will take the lead in launching the market, becoming the core "safe haven" for funds with their dual attributes of anti inflation and hedging. 2) As the global manufacturing industry enters a replenishment cycle and industrial recovery momentum is gradually released, industrial metals centered around copper and aluminum will take on the main trend of price increases. The rebound in demand coupled with rigid constraints on supply will push prices into an upward channel. 3) Subsequently, crude oil and petrochemicals continued to rise, serving as the core midstream category connecting industrial production and household consumption. It not only benefited from the recovery of industrial demand, but also simultaneously reflected the expectation of terminal consumption recovery, completing the midstream transmission link of resource goods rotation. 4) When the price increases of precious metals, industrial metals, and energy and chemical industries are fully demonstrated, and prices and valuations enter a high range, the transmission effect of price increases will spread comprehensively to the terminal livelihood sector. At this time, agricultural resources that are deeply tied to food security, household consumption, and a continuously tight supply and demand pattern often become the main theme of resource product rotation, ushering in a highly certain replenishment market. From this perspective, agricultural products are indeed likely to take over as the next main line.
