Trump issued a “last chance” diplomacy warning to Iran; however, Tehran promptly dismissed the proposal. Iranian military leadership has issued threats to foreign warships, asserting their refusal to allow a second corridor in the Strait. Fed Official Williams expressed confidence that current interest rates are appropriately set to reduce inflation to 2%. The US Dollar Index, which measures the value of the US Dollar against six major currencies, is extending its gains for the second successive day and trading around 100.00 during the European session on Tuesday. The Greenback maintains its strength against major counterparts as geopolitical tensions escalate following US President Donald Trump’s description of his recent proposal as a “last chance” for diplomatic resolution with Iran. The statement came after his decision to cancel a significant military strike, with Trump indicating that formal negotiations would likely commence soon to protect the Strait of Hormuz and tackle enduring US apprehensions about Iran’s nuclear program.

However, the Iranian leadership promptly dismissed the overture. General Mohsen Rezaei, an advisor to Iran’s Supreme Leader, unequivocally rejected the conditions, asserting that Tehran would categorically not permit a second corridor in the Strait. He further cautioned that any foreign warships or military forces dispatched to enforce such a corridor would be directly targeted. In light of recent developments, currency and financial markets are actively processing economic policy signals after the central bank opted to maintain interest rates at their current level in July. Traders are currently assigning approximately a 65% likelihood to a 25-basis-point rate increase at the Federal Reserve’s forthcoming September meeting, as indicated by the CME FedWatch tool.

Fed’s Williams delivers a moderately hawkish message, with a 6/10 FXS Speechtracker score slightly above the 5.8/10 historical average, underscoring confidence that current rate policy is “well positioned” to achieve the 2% inflation goal. The repeated commitment to act if inflation is not on track, alongside optimism that price pressures will gradually ease and that the Middle East war’s inflation impact will cool, signals a steady-hawkish stance rather than an escalation. Acknowledging market pricing as valuable but not binding, and downplaying financial stability risks from AI investment, reinforces a message of policy patience within a firmly anti-inflation framework. The FXS Fed Sentiment Index decreased by 1.47 points to 146.76, reflecting a slight reduction in perceived hawkishness.

Despite the decline, the index remains significantly above the neutral 100 mark, indicating that Fed communication continues to reside firmly in hawkish territory, even as the tone gradually approaches the established baseline. Analysts report that their “subsequent FCI-G estimate – updated after the July FOMC meeting – shows that while the equity-market sell-off, a stronger USD and higher long-term rates tightened financial conditions between the June and July meetings, these moves were moderate compared to the financial-market rallies of the past few months.” It is suggested that, in aggregate, the earlier strength in risk assets continues to offset the more recent bout of tightening.
