What it means

This is a foreign-exchange and bond-market update: the yen has fallen to around 158 per US dollar — meaning the dollar buys more yen — as a broad global sell-off in government bonds pushes long-term yields higher. The weakening is happening even after the Bank of Japan raised interest rates, because rising yields elsewhere, especially US yields, make dollar-based assets more attractive and keep pressure on the yen. In plain terms, Japanese money is getting cheaper against the dollar as global borrowing costs climb.

Past coverage

On 2026-09-03 we covered Japan's bond rout continuing and the BOJ leaving the door open for an outsized hike while the yen gained, alongside a deepening global bond sell-off that pushed UK 10-year yields to a 28-year high and US 30-year yields to their worst levels since 2006. Today's item is the next leg of that same story: the yen has now reversed course and slid to the 158 range as the global bond pressure persists.
