Dollar Index Hits 100.59 as Oil Volatility Clouds Inflation Path

The dollar index climbed to 100.59 on Tuesday, driven by conflicting signals from Iran and Fed officials regarding future inflation risks.
Key points
- The dollar index reached 100.59, its highest level since July 30, amid volatile oil trading.
- Markets price a 55.4% probability of a Federal Reserve rate hike at the October meeting.
- The dollar rose to 157.41 against the yen, extending its three-day winning streak.
The dollar index rose 0.17% to 100.59 on Tuesday, marking a two-month high. This gain occurred despite choppy trading and conflicting signals on oil prices.
Investors remained uncertain as crude oil prices fluctuated sharply. These swings directly impacted inflation expectations and central bank policy outlooks.
Oil Prices Drive Dollar Volatility
Crude prices fell to a two-week low before rebounding. President Trump’s comments on US-Iran negotiations created this market whipsaw effect.
Earlier optimism about reopening the Strait of Hormuz eased energy costs. However, later remarks suggesting a delayed deal pushed oil back above $100 briefly.
Fed Officials Signal Higher Rates
Federal Reserve Bank of Boston President Susan Collins supported recent rate hikes. She cited risks that inflation will remain above the 2% target.
Richmond Fed President Tom Barkin noted broadening inflation pressures beyond energy. Markets now price a 55.4% chance of an October rate hike.
Yen and Sterling Face Pressure
The dollar strengthened to 157.41 against the Japanese yen. This marked the third consecutive daily gain for the greenback.
Sterling weakened 0.23% to $1.3332 against the dollar. The British currency is now down for the second straight day.
