The US dollar is approaching 160 against the Japanese yen, putting fresh pressure on Japan as the currency continues to weaken. A stronger dollar and the widening gap between US and Japanese interest rates are keeping the pair elevated.
US Inflation Gives the Dollar a Boost
US inflation remains firm. October CPI rose 0.4% month-on-month, above the 0.3% market forecast. This has strengthened expectations that the Federal Reserve may keep interest rates higher for longer, giving the dollar another lift.
The yen, meanwhile, remains under pressure as Japanese interest rates are still far below US levels.
Japan Faces a Tough Choice
Japan's inflation problem is becoming harder to ignore. October's corporate goods prices rose 7.1% year-on-year, while yen-based import prices jumped 24.8%.
A weaker yen is making imported energy and raw materials more expensive. This could add pressure on the Bank of Japan to raise interest rates, although any policy move will depend on how the economy develops.
Japanese officials have also stepped up warnings against excessive currency movements, keeping the possibility of another intervention on the radar.
160 Is Getting Closer
The 160 level is becoming a major test for USD/JPY. A break above it could attract more dollar buying, particularly if US rate expectations remain firm.
But Japan may not sit back and watch the yen weaken further. Any intervention could trigger a sharp reversal, making the next move increasingly difficult to predict.
For now, the dollar still has the upper hand. But the closer it gets to 160, the greater the risk that Japan steps in.
