Japan's Failing Yen: A Warning for the Global Economy?

Summary

Imagine a coal miner relying on a canary to detect deadly gas. For decades, Japan has served as that canary for the global economy, and its bird has stopped singing. Japan faces an unprecedented debt crisis, with its government debt at roughly two hundred fifty percent of its economy. This situation is exacerbated by its heavy reliance on imported oil, with almost all of it coming through the Strait of Hormuz. The Japanese yen has fallen to a near forty-year low, making oil imports even more expensive and creating a 'doom loop' of a weaker yen and higher oil bills. Japan pioneered many of the economic tools used today, like zero interest rates and quantitative easing, but these have led to a generation of minimal savings returns and stagnant growth. Now, the central bank can no longer afford to buy government bonds to keep borrowing costs low, as this would further weaken the yen and increase the oil bill. This has caused lenders to demand higher returns, and Japan is beginning to sell off assets like US treasuries. The yen carry trade, where investors borrow cheap yen to invest elsewhere, is also facing unwinding, which could destabilize global markets. A small interest rate hike in August of this year caused significant global market downturns, hinting at the potential fallout from future, larger moves. While the US has advantages like its reserve currency status, Japan's current predicament serves as a stark warning for economies facing similar debt burdens and the consequences of prolonged easy money policies.
