Japan raised interest rates for the first time in 30 years, a signal that has stirred ripples in global markets. Those old tactics that relied on Central Bank policy arbitrage are beginning to fail, and investors are in a hurry to find safe-haven assets that do not depend on Central Bank easing.

Why are many people turning their attention to decentralized stablecoins? Simply put, it's because they no longer want to be held hostage by the cyclical nature of Central Banks. Stablecoins like USDD, which operate through algorithmic mechanisms and over-collateralization, provide an alternative outside the traditional financial system—its stability comes from actual reserves on the chain, rather than from a Central Bank saying "Don't worry, we have money."

Some people are concerned about the risks. Indeed, Japan has a high level of debt and the zombie company problem has not yet been resolved. Once global liquidity really begins to tighten rapidly, all assets will need to be re-evaluated. However, on the flip side, it is precisely in this extremely uncertain environment that the over-collateralization ratio of over 130% for USDD, coupled with the ecological support based on blockchain high-frequency interactions, may actually demonstrate resilience. Because its foundation is visible on-chain data, rather than promises and expectations.

A deeper change is: when the yen is no longer the cheapest arbitrage tool, the pricing logic of global assets is being reshaped. Decentralized stablecoins are becoming the new reference point - replacing power and credit ratings with mathematics and transparency, redefining what "stability" means.

The source of water has begun to rise in price, and the old path is no longer viable. Perhaps the stability of the future lies in establishing algorithms and recording such things on the chain—not to replace anything, but to open up a new flow method in the gaps of the old system.
