The US Dollar Index (DXY) has extended its losses, trading at 100.75 on Friday after rebounding from a three-week low of 100.56, marking its third consecutive day in the red [1][2][5]. This decline comes as mediating countries, including Qatar and Pakistan, work to bring the United States and Iran back to the negotiating table, following a pause in tit-for-tat strikes between the two nations [1][2]. A US official confirmed that the US has been striking and then pausing deliberately to avoid escalation and allow diplomacy to progress [1]. Al Jazeera reported that Washington remains committed to negotiations and diplomacy, with technical talks ongoing [2]. However, Source 5 notes a discrepancy, citing President Donald Trump’s statement that the memorandum of understanding (MoU) with Tehran is over, and expressing skepticism about Iran honoring any deal, despite Iran's apparent eagerness for an agreement [5].
The risk-positive market atmosphere, reflected in bullish action on Wall Street's main indexes, has further pressured the US Dollar, making it difficult for the currency to stay resilient against its peers [2]. The Dollar was the weakest against the New Zealand Dollar (NZD), falling 1.06% this week, and also lost ground against the British Pound (-0.57%), Canadian Dollar (-0.25%), and Australian Dollar (-0.18%) [2]. The NZD/USD pair traded at 0.5775, its strongest level in three weeks, following a hawkish 25 basis point rate hike by the Reserve Bank of New Zealand (RBNZ), with traders fully pricing in two additional quarter-point hikes through December [4].
Oil prices surged nearly 10% from last week’s lows due to reduced traffic through the Strait of Hormuz, benefiting the USD but hurting the Euro and Japanese Yen due to their economies' exposure to higher energy prices [1]. However, a steep correction in oil prices later in the week supported a rise in Silver prices (XAG/USD), which traded 0.4% higher at $60.22 as the US Dollar weakened [5]. The WTI Crude Oil price held onto Thursday’s losses near $72.00 [5].
In Japan, Finance Minister Satsuki Katayama announced plans to encourage pension funds to invest more in domestic assets, leading to Yen appreciation and adding further pressure on the Dollar [1]. Meanwhile, New York Fed President John Williams delivered a hawkish speech, emphasizing that inflation remains 'far too high' and that monetary policy is closely monitoring energy developments [2]. ING’s Francesco Pesole noted that Middle East tensions have modestly re-tightened EUR/USD short-term swap rate differentials by around 10bp, but the path for sustained Euro strength against the Dollar remains narrow, with downside risks including a possible retest of 1.140 [3].
Looking ahead, investors are focused on the upcoming US Consumer Price Index (CPI) data for June, which is expected to be released next week [5].
CONCLUSION
The US Dollar Index has come under sustained pressure due to ongoing US-Iran diplomatic efforts, shifting global risk sentiment, and central bank actions. Market participants are closely watching geopolitical developments and upcoming US inflation data for further direction. The overall market takeaway is heightened volatility and a cautious outlook for the Dollar, with significant cross-currency moves and commodity price reactions.
