US October inflation data came in above market expectations, serving as the core trigger for this round of dollar strength.
Several Federal Reserve officials subsequently shifted toward hawkish rhetoric, rapidly heating up market expectations for further monetary tightening. Traders have already begun pricing in the risk of a one-time 50 basis point rate hike in December, and the benchmark 10-year US Treasury yield climbed back above 5% on Wednesday, with rising yields providing direct support for the dollar.
Fed Governor Waller's remarks further reinforced tightening expectations, with his speech sentiment score significantly above the historical average. He explicitly stated that if core CPI holds at 0.3% or above on a month-over-month basis, conditions would warrant a 50bp hike in December; even if inflation data improves modestly, he would lean toward at least a 25bp increase. He also noted that current policy restrictiveness is less than previously judged and that real interest rates need to rise further. These comments pushed the FXS Fed sentiment index sharply higher, above the neutral threshold, continuing to benefit the dollar while pressuring non-dollar currencies such as the euro and yen.
Geopolitical risks have flared up again, with no signs of de-escalation in the US-Iran standoff over the Strait of Hormuz. US forces struck Iran's Qeshm Island, while Iran attacked the vessel navigation system on Oman's Daymaniyat Islands. A senior Iranian military official stated that this strategic waterway would only be opened under the Supreme Leader's directive. Market expectations for a diplomatic resolution to the US-Iran conflict have cooled, driving safe-haven flows into the dollar and further consolidating the dollar index's upward trajectory, with the path of least resistance now more clearly to the upside.
In the near term, the market will continue to track US weekly initial jobless claims data, while public speeches from multiple FOMC officials and sudden Middle East geopolitical developments will provide new volatility drivers for the dollar index. On the 4-hour chart, the dollar index maintains a short-term bullish structure, with the price having broken above the 102.40-102.50 resistance zone and holding above that level, opening up further upside space. The current price continues to trade above the 4-hour 200-period exponential moving average, with the moving average system providing support for prices and a clear bullish trend signal. In the event of a pullback, the first support level sits near 101.55 at the 200-period EMA, a key defensive level for bulls where buying interest is likely to emerge, maintaining the overall uptrend. On the upside, near-term resistance is seen around 103.30, with further targets looking toward the extension of previous highs.
Editor's Summary
The current dollar is driven by two main themes: first, sticky inflation driving a repricing of Fed rate hike expectations and higher Treasury yields; second, recurring Middle East geopolitical conflicts providing sustained safe-haven demand. Technically, the bullish structure remains intact with a clear trend advantage. Risks to watch include short-term overpricing of inflation expectations, a sudden easing of geopolitical tensions triggering rapid profit-taking, and weaker-than-expected evening employment data prompting a dollar pullback.
