The dollar held firm against most peers on Friday, as a peace deal between the U.S. and Iran hung in the balance, pinning the yen around a two-year low, a break past which would take the Japanese currency to its weakest in 40 years.
The dollar climbed as high as 161.8 yen late on Thursday, closing in on July 2024's 161.96. Any higher would take it to its strongest against the yen since 1986.
