USD edged higher in international markets.
On the international market, the Dollar Index (DXY), which measures the strength of the USD against a basket of six major currencies, closed at 98.60 points, up 0.17%. Overall for the week, the DXY rose by approximately 0.32%, indicating a return to stability for the US dollar.
According to Reuters, the US dollar strengthened against most major currencies after the Bank of Japan (BoJ) raised interest rates. This decision caused the USD/JPY exchange rate to surge by 1.38%, to 157.69 yen/USD.
US government bond yields also rose in line with the general trend. The 10-year yield increased by 3.3 basis points to 4.149%, while the 2-year yield, which reflects the Federal Reserve's policy expectations, rose to 3.486%.
Macroeconomic factors at play
Economic data released this week in the US, particularly the consumer price index (CPI), showed that inflation is cooling, raising expectations that the Fed may soon ease monetary policy. In addition, the number of initial jobless claims rose to 236,000, reflecting signs of a slowdown in the labor market.
Recent statements by US President Donald Trump have also impacted market sentiment. He said the next Fed chairman would be a "strong supporter of interest rate cuts," further reinforcing expectations of an easing cycle in the first half of next year.
