LONDON—The dollar hit the symbolic level of 150 yen for the first time since 1990 on Thursday as the greenback was supported by Treasury yields trading at multi-year highs, keeping markets on high alert for intervention from Japanese authorities.
Moves among other major currencies were muted by recent standards. The euro up 0.5 percent at $0.9826, regaining a little of the ground it lost during a dollar surge the day before, while turmoil in British politics meant sterling stayed soft.
The fragile yen briefly weakened past 150 per dollar in early European trading for the first time since August 1990. It was last trading a touch below that level, at 149.7 yen per dollar.
The Japanese currency has been on a losing streak for 11 straight sessions as of Wednesday’s close, and has renewed 32-year lows for six sessions now.
“As long as the terminal point of the U.S. interest rate remains unclear, dollar strength will not subside. 150 was just a pass point, and the focus now is on if it tops 160,” said Takumi Tsunoda, senior economist, Shinkin Central Bank Research Institute in Tokyo.
The Federal Reserve is expected to continue raising interest rates as inflation remains stubbornly hot in the United States, with some forecasting a peak above 5 percent.
This has sent U.S. yields and the dollar higher, particularly against the yen as the Bank of Japan is committed to keeping interest rates near zero.
The benchmark U.S. 10-year Treasury yield rose to 4.18 percent on Thursday, its highest level since mid-2008, while the two-year Treasury yields touched a 15-year high of 4.614 percent.
Traders were also watching to see whether the breach of the 150 level would cause Japanese authorities to repeat last month’s intervention in currency markets, their first time doing so to support the battered currency since 1998.
“The (Ministry of Finance) has been very clear that they are ready to intervene if there is any disorderly price action, so the markets are priced for that coming at some point in time,” said Derek Halpenny, head of research, global markets EMEA at MUFG.
“Obviously, if we break clearly above 150 we may see some disorderly price action and that could be the catalyst for some action so it’s just basically all eyes on MOF,” he added, though emphasizing it would take a sharp move in the pair to trigger intervention.
UK Turmoil
In Europe, the euro climbed 0.4 percent on the pound amid political turmoil in the United Kingdom, with the departure of the interior minister putting further pressure on Prime Minister Liz Truss.“Political infighting and the uncertainty of policy continue to demand a risk premium for sterling, where GBP/USD could easily slip back to the bottom end of its wide 1.10-1.15 range,” said ING analysts in a note.
“The wild card is what happens to the top job.”
Sterling was last flat versus the dollar at $1.1231.
The surging greenback also pushed the Chinese offshore yuan to a record low in Asia of 7.2794 early in the session, its weakest level since such data first became available in 2011.
Other currencies including the Australian and Canadian dollars and the Swiss franc, regained a little of their losses against the U.S. dollar from the previous day.
