The dollar bought about 157.5 yen on Friday, October 30, 2026, after the Bank of Japan held its policy rate steady, according to market data. The yen has been weighed down by the wide difference between interest rates in the two countries.

The dollar itself slipped slightly on the day. The dollar index, which tracks the US currency against a basket of major peers, edged lower to 101.92. The euro traded at $1.1166 and the British pound at $1.3389.

Why the yen stays weak

Currencies are heavily influenced by interest-rate differences between countries. Investors tend to favor currencies that offer higher returns, and US rates remain well above those in Japan. As long as that gap persists, holding yen offers less income than holding dollars, which can keep the Japanese currency under pressure.

The Bank of Japan's decision to hold rates did nothing to narrow that gap. Across the Pacific, the Federal Reserve is leaning toward raising rates. The Fed left its benchmark rate range unchanged at its October 27-28 meeting, but Governor Lisa Cook and Cleveland Fed President Beth Hammack dissented in favor of a quarter-point hike. Markets are pricing in a December increase, according to CME FedWatch data cited by market data, and LSEG data cited by market data showed markets pricing in more than two quarter-point hikes by mid-2027.

Fed officials talk up hikes

On Friday, three Fed officials argued for tighter policy. St. Louis Fed President Alberto Musalem said, "I judge that additional firming of Monetary Policy will be necessary, and soon." Dallas Fed President Lorie Logan said she wants at least two more quarter-point hikes, and Richmond Fed President Tom Barkin said, "I think the question though is pace."

Treasury yields nonetheless fell on Friday, and the 10-year yield dropped sharply over October, according to market data. Lower US yields can ease some pressure on the yen, but the overall difference in rates remains wide.

A turbulent session

Friday's market moves gave currency traders plenty to digest. The S&P 500 fell 140.32 points to 7,580.07, the Dow Jones Industrial Average dropped 572.25 points to 51,770.31 and the Nasdaq Composite lost 747.73 points to 25,437.00, its worst day since June. Intel (NASDAQ:INTC)'s cash-burn warning set off a global chip rout that hit semiconductor stocks around the world.

Energy prices matter for Japan, which imports most of its oil. West Texas Intermediate crude rose $2.12 to $104.12 a barrel, and Brent settled at $113.43, amid tanker incidents in the Strait of Hormuz and reports that the United States could resume strikes on Iran. Higher oil Import costs can weigh on the trade balance of energy-importing countries.

What to watch

The biggest near-term driver for the yen is likely to be US data. The October jobs report on Friday, November 6, and the Institute for Supply Management's surveys next week will shape expectations for the Fed's December decision. A strong set of numbers would support the case for a hike and could keep the dollar firm against the yen.

The Bank of Japan's next steps are also in focus. Any sign that it is preparing to raise rates would narrow the gap with the United States, while continued holds would leave the current dynamic in place.

Investors will also watch oil prices and the midterm elections on Tuesday, November 3. With the yen near 157.5 per dollar, moves in US yields and in energy markets are likely to remain the main forces behind the currency's direction in the weeks ahead.
