United States Dollar Index hold gains above 99.50 as Treasury yields hit multi-year highs

The US Dollar Index (DXY) has been surging for two days straight, trading near 99.70 during Asian trading hours on Wednesday. The strengthening Greenback is attributed to surging bond yields and soaring oil prices, which have raised concerns about persistent inflation and potential interest rate hikes. The US 10-year Treasury yield reached a multi-year high of 4.80%, following a global bond selloff.

Additionally, crude oil prices surged due to heightened tensions between the United States and Iran, adding to inflation worries due to potential disruptions in energy supplies from the Middle East.

However, recent US economic data presents a mixed picture for market sentiment. July JOLTS job openings fell below expectations at 7.27 million, and the ISM Manufacturing PMI eased slightly to 54.6 in August. Nonetheless, the PMI remains in expansion territory, indicating a resilient manufacturing sector. Traders are now monitoring the upcoming ADP employment report and Friday's nonfarm payrolls to gauge the Federal Reserve's next move on interest rates.

Experts at Brown Brothers Harriman argue that the recent spike in Treasury yields is not primarily driven by concerns over US fiscal sustainability, but rather due to the "outperformance of US 10-year Treasuries relative to other major bond markets." While this relative outperformance does not eliminate fiscal risks, it does suggest that the US Dollar may be more vulnerable to periods of fiscal stress.

The US Dollar (USD) is the official currency of the United States and a widely accepted "de facto" currency in numerous countries. It is the most heavily traded currency globally, accounting for over 88% of all foreign exchange turnover, averaging $6.6 trillion in transactions daily. The USD replaced the British Pound as the world's reserve currency following World War II and was backed by gold until the 1971 Bretton Woods Agreement.

The primary driver of the USD's value is monetary policy set by the Federal Reserve (Fed), which aims to maintain price stability (inflation control) and promote full employment. The Fed adjusts interest rates to achieve these goals. Higher rates benefit the USD, while lower rates weaken it. In exceptional circumstances, the Fed can also implement quantitative easing (QE) to boost credit in a stagnant financial system, which typically results in a weaker USD.
