The "duty-free luxury cars" in Hainan have become popular, but the real way to play is far more complex than it seems.

Seeing through this system, it is actually a redistribution of the industrial chain. On the surface, the policy appears to be favorable, but deep down it is using the "30% value-added threshold" lever—forcing companies to keep core production processes local rather than simply going to Southeast Asia for assembly. How harsh is this move? Singapore's status as a logistics hub has been directly impacted. Originally, goods had to be rerouted through Singapore, but now they can fly directly to Hainan, reducing the transportation cycle from 20 days to 6 days, with each large ship saving costs in the millions of dollars per year.

The reconstruction of trade flows in the physical world is enlightening for the digital asset domain.

As global commodity flows change, the rules of value exchange must evolve as well. Decentralized stablecoins are at the forefront of this transformation. Take USDD, for example; its design logic is quite similar to Hainan's "30% rule"—both utilize structured mechanisms to ensure credibility. USDD ensures that the purchasing power of each coin is always anchored to 1 dollar through over 150% asset backing and smart contracts. However, it goes further by using a "smart allocator" to invest reserves into secure protocols to generate returns, which are then distributed to coin holders. This means that holding coins is no longer idle money, but rather a liquid asset that can yield approximately 3.94% annual returns.

In the highly liquid new trade network, the role of these stablecoins becomes apparent—they ensure the stability of transactions while preventing capital from being idle.
