Dollar wobbles as Treasury's bond-market buybacks raise fresh concerns

On Friday, the dollar experienced a decline and appeared set to close the week lower, as investors became skeptical about whether the U.S. Treasury's attempts to stabilize bond markets might ultimately weaken trust in the currency. This uncertainty caused the euro to increase by 0.13%, reaching $1.1694, and on track for its fourth consecutive weekly increase. The British pound also rose 0.15% to $1.3652, hovering near its highest level since May.

Treasury Secretary Scott Bessent indicated on Thursday that the government might expand its purchases of Treasuries further, following its surprise announcement the previous day to double the size of the buybacks for longer-dated debt in an effort to curb bond yields. However, some experts argued that these measures to stabilize longer-term yields could merely redirect pressure to other areas of U.S. markets, with the dollar potentially facing the brunt of the impact.

The hint of financial repression and unconventional policies could be detrimental to the dollar, according to Jonas Goltermann, chief markets economist at Capital Economics. He expressed doubts about the dollar's rebound, as forecasted for the coming months.

The developments in the currency markets come amid a range of uncertainties, including the ongoing Iran war and the trajectory of interest rates. Moreover, they set the stage for a challenging environment for the Federal Reserve's Jackson Hole symposium next week, where Chair Kevin Warsh's speech will be closely examined to glean insights into central bankers' perspectives on the latest data and Treasury actions.

The dollar index, which gauges the U.S. currency against a basket of six peers, was on track for a weekly decline of approximately 0.94% and was currently at 98.72, nearing a three-month low. Meanwhile, the Japanese yen gained 0.14% against the dollar to 158.81 following reports that core consumer inflation had accelerated in July, supporting the argument for a rate hike by the Bank of Japan.

Authorities from both nations had previously supported the yen through joint intervention last month; however, analysts suggest the Japanese currency might resume its decline unless the Bank of Japan tightens policy. The BOJ's next policy meeting is scheduled for September 17-18.
