Dollar Jumps After Middle East Attacks, Hormuz Closure Drives Oil Price Surge

Market Reactions and Economic Implications

By Gregor Stuart Hunter

Currency Movements Amid Middle East Tensions

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.

Major Currency Pairs

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.

Geopolitical Developments and Oil Prices

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 Price Surge

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

Analyst Commentary

"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."

Interest Rate Expectations

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

Fed Funds Futures

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.

Dollar Index Performance

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 and Central Bank Outlooks

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.

Bank of Japan's Economic Forecast

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.

Cryptocurrency Market Update

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