The Japanese government is now openly admitting what I have been warning about for years. Rising interest rates are beginning to dramatically increase the government’s debt-servicing costs. For decades, Japan survived by suppressing interest rates to nearly zero while endlessly rolling over debt. That strategy only works so long as rates remain artificially low. Once rates begin to rise, the mathematics become impossible to hide.

Japan’s government debt exceeds 230% of GDP, the highest ratio in the developed world. Politicians, academics, and central bankers have spent years arguing that Japan was different because most of the debt was held domestically. I repeatedly rejected that argument. Debt is debt and whether the creditor lives in Tokyo, London, or New York does not change the obligation. The real issue has always been confidence. Once investors demand higher yields to compensate for risk, interest expense explodes and governments enter the classic sovereign debt spiral.

The Bank of Japan has now raised rates to 1%, the highest level since 1995. That may sound insignificant compared to rates elsewhere, but Japan built its entire fiscal structure around the assumption that rates would remain near zero forever. The government became addicted to cheap money. Every welfare program, subsidy, and stimulus package rested on the ability to borrow endlessly at virtually no cost. That era is ending.

What many fail to understand is that sovereign debt crises never begin because governments run out of money overnight. They begin when interest costs consume an ever-larger share of tax revenue. Governments then borrow more simply to pay interest on previous borrowing. Japan crossed that line years ago. The entire system has been held together by the Bank of Japan purchasing enormous quantities of government debt. Once the central bank attempts to normalize policy, the market immediately begins questioning the sustainability of the entire structure.

This is why I have long argued that Japan would likely be the first major developed nation to face the sovereign debt crisis head on. The population is aging, the tax base is shrinking, and social obligations continue to rise. There is no realistic path to paying down the debt. Governments always believe they can borrow forever until suddenly they cannot. History has demonstrated this repeatedly, from ancient Rome to modern Europe.

The significance extends far beyond Japan. Every major government has followed the same path. The United States, Europe, Britain, and Canada all expanded debt under the assumption that central banks could permanently suppress rates. Japan simply arrived at the end of the road first because it accumulated debt faster than everyone else.

Our models continue to show that the period into 2032 remains the critical phase for sovereign debt. The crisis was never about private debt. Governments became the largest borrowers in history. The next monetary restructuring will emerge not because of banks or corporations, but because governments have accumulated obligations that can never realistically be honored in full. Japan is merely the first warning shot. The sovereign debt crisis has begun, and once confidence starts to crack, governments everywhere will discover that there is no such thing as endless borrowing.
