The AUD/USD pair held onto mild gains during Monday's early Asian session, hovering near the 0.7175 level. The US Dollar (USD) traded lower against its Australian counterpart as market participants continued to digest concerns surrounding the US Treasury's strategy to expand buybacks of longer-dated government debt. Meanwhile, the Reserve Bank of Australia (RBA) is scheduled to release its meeting minutes on Tuesday.
US Treasury Buybacks and Dollar Weakness
US Treasury Secretary Scott Bessent stated on Thursday that the department could increase bond buybacks beyond $4 billion, an initiative partly aimed at signaling that prevailing yields do not align with core economic fundamentals. This policy discussion followed an earlier market surprise when the department pledged to at least double the scale of its longer-dated debt buybacks to help rein in surging bond yields.
Marc Chandler, chief market strategist at Bannockburn Global Forex, noted that efforts by Bessent to suppress U.S. yields have had limited impact on yields themselves while actively undermining the dollar, adding that the market is pushing back against these measures. Demonstrating a shift from its standard calendar, the department announced on Wednesday at 12:32 GMT that it would at least double liquidity support buyback operations across the 10-year to 20-year and 20-year to 30-year sectors, raising the maximum cap from $2 billion per operation to at least $4 billion, effective from September 9 through November 4.
Middle East Tensions and Iranian Stance
Downside pressure on the US Dollar was partially cushioned by rising geopolitical tensions in the Middle East, which bolstered safe-haven flows. Iranian Foreign Minister Abbas Araghchi dismissed the threat of new US economic sanctions on Sunday, labeling them as a sign of desperation and asserting that the anticipated measures would fail to defeat Tehran. Concurrently, Iran’s Security Chief Mohsen Rezaei warned of earthquake-like retaliation should US President Donald take further aggressive steps.
On the domestic front, a recent report from DBS highlighted a negative surprise in Australia's labor market data, noting that the economy recorded 15.8k job losses in July, diverging sharply from analysts' expectations of a 12k increase in employment. This unexpected contraction adds an important layer of scrutiny for upcoming Australian economic releases, including the July Consumer Price Index (CPI) report and its implications for future RBA policy expectations.
Economic Drivers and Technical Levels
The valuation of the Australian Dollar is fundamentally influenced by RBA interest rate decisions, commodity export prices led by Iron Ore, and the economic trajectory of its largest trading partner, China. Additional determinants include domestic inflation, trade balance figures, and broader market sentiment oscillating between risk-on and risk-safe postures. Iron Ore remains Australia's primary export earner, with historical trade volumes heavily directed toward China.
From a technical perspective, initial downside support for the AUD/USD pair rests near the 100-day moving average at 0.7072, backed by the 20-period Bollinger middle band positioned just below at 0.7065, with a deeper structural floor near the lower Bollinger band at 0.6955. On the topside, immediate resistance is marked by the upper Bollinger band at 0.7175. A decisive and sustained breakout above this barrier could pave the way for extended gains, whereas a failure to clear it might precipitate a corrective retreat back toward the support cluster.
Similar currency pairs reflected subdued momentum at week's end. The GBP/USD pair retreated toward the low 1.3600s after touching intraday peaks above 1.3670, while EUR/USD traded lower around 1.1670 following a failed attempt to decisively breach the 1.1700 threshold. Meanwhile, gold pulled back slightly from multi-month highs touched during the Asian session, successfully maintaining support above the $4,600 mark despite persistent macroeconomic crosscurrents.
