Japan debt limits rate-hike flexibility

Japan’s inflation problem is difficult to solve through aggressive rate hikes because of the country’s debt burden.
At roughly 235% debt-to-GDP, higher rates would put major pressure on fiscal sustainability.
That is why the market is watching the yen as a possible pressure-release valve.
A stronger $JPY could help tighten financial conditions and force parts of the yen carry trade to unwind.
The risk is that a sharp yen surge could create stress across global risk assets, especially if crowded carry positions begin to reverse quickly.
The bigger signal is that Japan’s policy options remain constrained by debt, inflation, and currency stability at the same time.
