SINGAPORE, July 13 (Reuters) – The dollar jumped against most of its peers as a renewal of conflict in the Middle East fanned inflation fears and the prospect of rate hikes from central ​banks increased.

Against the yen, the U.S. dollar was up 0.1% at 161.92 ‌yen. The euro weakened 0.1% to $1.1403 while the British pound slipped 0.1% to $1.3383.

The Australian dollar was down 0.1% at $0.6942, while its kiwi counterpart slid 0.1% to $0.5757.

U.S. and Iranian forces exchanged heavy missile and drone assaults at the weekend, with Tehran targeting U.S. facilities in states across the ‌Gulf ​on Sunday and saying it had again closed the ⁠vital Strait of Hormuz.

Oil prices ⁠rose as trading resumed in Asia, with Brent crude futures up 3.3% at $78.49 a barrel.

“After the flare-up into the end of last week which continued over the weekend, the dollar has responded, and the crude oil price has ​been the driver,” said Tony Sycamore, market analyst at IG in Sydney. “This reinflames concerns that if the energy prices rise from here, we could start to ⁠see rate hikes pulled forward.”

Traders are leaning slightly ⁠in favour of two rate hikes from the Federal Reserve ​by the end of the year.

Fed funds futures are pricing an implied 52.1% probability ​of two or more rate hikes by the time of the U.S. ‌central bank’s December meeting, compared to a 47.6% chance on Friday, according to the CME Group’s FedWatch tool.

The U.S. dollar index, which measures the greenback’s strength against a basket of six currencies, held steady at 101.07 after rising as much as ⁠0.2% from Friday’s close to its highest level since July 8.

Inflation risks are likely to remain in focus during the coming week, ahead of the release of U.S. CPI ⁠data on Tuesday, PPI ‌gauges the following day, and Fed Chair Kevin Warsh’s testimony before ⁠the House and Senate, Westpac analysts wrote in a ​research report.

The ‌Bank of Japan may revise up its economic growth forecast ​for fiscal ⁠2026 and keep its focus on the risk of an inflation overshoot as rising costs from a weak yen and strong AI demand offset some of the declines in oil prices, three sources familiar with the central bank’s thinking told Reuters.

In cryptocurrencies, bitcoin was down 0.6% at $63,770.42, while ether slipped 1.1% to $1,801.28.
