Dollar Surges as Oil Prices Soar and ECB Tightening Cycle Nears End

The dollar index rose to its highest point in seven weeks on Wednesday due to growing concerns about the economic impact of rising oil prices and diverging monetary policy paths across major economies. The US economy is less exposed to energy shocks than many other major economies, attracting demand for the greenback at the expense of currencies like the euro and yen.

Most economists expect the European Central Bank to finish its tightening cycle by the end of this year after next week's widely anticipated rate hike. In contrast, the Federal Reserve is confronting a growing risk of having to tighten policy in 2027, according to George Brown, senior economist at Schroders.

The dollar index rose 0.11% to 99.76, with the euro down 0.16% at $1.1575 and Japan's benchmark 10-year yield extending its rally to 3.01%. The US Treasury Secretary voiced strong support for 'decisive' monetary steps to combat yen weakness in a meeting with BOJ Governor Kazuo Ueda.
