(SeaPRwire) –   The U.S. dollar reached a six-week high on Wednesday as market participants assessed the likelihood of Federal Reserve interest rate hikes intended to combat inflation resulting from the ongoing conflict in Iran.

The dollar index, which tracks the greenback against a basket of six major currencies, increased by 0.1% to 99.47, marking its strongest performance since May 7. The index has gained more than 1.3% during the month of May.

Iran War Keeps Inflation Fears Alive

The hostilities have effectively shuttered the Strait of Hormuz, obstructing approximately one-fifth of global oil supplies. Brent crude is currently trading near $110 per barrel, representing a rise of over 50% since the conflict commenced in late February.

This spike in energy costs has directly influenced inflation metrics, placing the Federal Reserve in a challenging position. According to CME FedWatch, traders now anticipate a better-than-even chance of a rate hike by December, a notable shift from earlier this year when two rate cuts were expected.

President Donald Trump mentioned that the U.S. might need to take further military action against Iran, though he also suggested that Tehran is open to negotiations. Oil prices saw a minor decline on Wednesday following reports from Washington that discussions were advancing, though the drop remained contained.

On Tuesday, Philadelphia Federal Reserve President Anna Paulson remarked that market speculation regarding rate hikes is “healthy,” noting that current monetary policy appears to be sufficiently restrictive.

The euro declined by 0.16% to a six-week low of $1.158, while the British pound dropped to $1.338, also nearing a six-week low. The Australian dollar remained relatively stable at $0.711, following a 0.9% decrease in the previous session.

Yen Slides Back Toward Danger Zone

The Japanese yen has retreated toward the 160-per-dollar threshold, a level that prompted government intervention last month. Although Tokyo intervened in late April and early May to curb the yen’s depreciation, the impact was temporary.

As of Wednesday, the yen was trading at 159.01 per dollar. U.S. Treasury Secretary Scott Bessent indicated that Washington favors further rate increases by the Bank of Japan, expressing confidence that the BOJ governor would take necessary actions if granted sufficient autonomy.

Market analysts have cautioned that intervention might only delay the dollar-yen’s upward trajectory rather than reverse it, unless there is a decline in U.S. Treasury yields and the broader dollar. The 30-year U.S. Treasury yield reached its highest level since 2007 this week, serving as a primary catalyst for the dollar’s strength.

The Indian rupee hit a record low of 96.784 per dollar on Wednesday. India’s heavy reliance on energy imports leaves its currency particularly susceptible to surges in oil prices. Furthermore, investors are questioning the capacity of the Reserve Bank of India to effectively support the rupee.

The Chinese yuan saw a slight decline against the dollar. Meanwhile, geopolitical tensions between China and Taiwan have intensified after President Trump questioned future U.S. arms sales to Taipei and cautioned against any declaration of independence. Taipei has indicated it would welcome direct communication with the president.

Investors are awaiting the release of the Federal Reserve’s meeting minutes later on Wednesday, looking for any indications regarding the future direction of interest rates.
