The U.S. dollar has strengthened against major currencies amid ongoing Russia-Ukraine peace talks and concerns over potential tariffs proposed by President Donald Trump. The dollar index rose to 107.08, reflecting safe-haven demand as geopolitical tensions persist. Meanwhile, the Japanese yen also gained as a safe-haven currency, while the New Zealand dollar declined following a rate cut by the Reserve Bank of New Zealand. Oil prices remain elevated, with Brent crude trading near $76 per barrel and West Texas Intermediate around $72, driven by supply disruptions in Russia and the U.S., uncertainty over sanctions, and disruptions to Kazakh oil flows. The American Petroleum Institute reported a 3.3 million-barrel increase in U.S. crude inventories, signaling weaker demand. Efforts to resolve the Russia-Ukraine conflict continue, with talks between U.S. and Russian officials in Saudi Arabia, though no concrete outcomes have been announced. Additionally, Trump has proposed tariffs on imported goods, including automobiles and semiconductors, raising concerns over potential trade tensions. The EU has also imposed a new sanctions package targeting Russia, including a ban on aluminum imports, while Ukraine's attack on a CPC oil station has further intensified supply concerns.
