The US dollar rose for the fifth consecutive day.

The US dollar continued its upward trend on May 15th, marking a five-day winning streak and heading towards its strongest weekly gain in two months. This trend is occurring amid growing market expectations that the Federal Reserve's monetary policy path will favor interest rate hikes.

The dollar's upward momentum is firmly supported by the rise in US Treasury yields. The 10-year Treasury yield reached 4.599% – its highest level in over a year. A series of economic data released earlier this week showed increasing price pressures in the US, as energy supplies through the Strait of Hormuz remain blocked due to the conflict in Iran.

The DXY index, which measures the strength of the US dollar against a basket of major currencies, rose 0.32% to 99.27 points, after briefly touching 99.302 points during the session. Conversely, the euro fell 0.39% to $1.1623/euro, after hitting a five-week low of $1.1617/euro. Overall for the week, the DXY index gained approximately 1.5% – marking its longest five-day winning streak since the end of March 2016.

In the foreign exchange market, the Japanese yen fell 0.25% against the US dollar, recording an exchange rate of 158.74 yen/USD on May 15th. Data released on the same day showed that Japan's wholesale inflation in April 2026 accelerated at its fastest pace in three years due to sharp increases in oil and chemical prices because of the conflict in Iran. This strengthens the likelihood that the Bank of Japan (BOJ) will raise interest rates in June.

Overall for the week, the yen depreciated by more than 1%, gradually approaching the 160 yen/USD threshold – a level that would have prompted Japanese authorities to intervene directly in the financial markets in 2024.

In Europe, the euro lost around 1.4% this week, its biggest weekly drop in two months. The British pound (GBP) fell 0.57% to a five-week low of $1.3313/GBP. The UK currency has fallen more than 2% this week – its biggest weekly drop since November 2024 – amid growing political uncertainty surrounding Prime Minister Keir Starmer's leadership.
