The U.S. dollar strengthened for a second consecutive session, reaching its highest level in about a week. This advance was driven by renewed fears of escalating conflict between the U.S. and Iran, prompting investors to seek refuge in safe-haven assets. U.S. President Donald Trump declared an interim memorandum of understanding with Iran to end their conflict "over," leading to renewed strikes by the U.S. on Iran and a subsequent rise in oil prices.

The U.S. dollar index, a measure of its value against a basket of six major currencies, remained largely unchanged at 101.19. The currency experienced some volatility during trading but maintained its upward trend as geopolitical tensions resurfaced.

This development signals a flight to safety among investors, who are prioritizing security over riskier assets amid heightened international instability. The rise in oil prices also reflects the market's reaction to potential supply disruptions stemming from the conflict.
