The US Dollar Index (DXY), which tracks the Greenback against a basket of six major global currencies, preserved its upward momentum on Tuesday, logging gains for the fourth straight session and moving back toward the nearly two-week high reached during the prior day. The benchmark index was hovering near the 99.65 mark in early European trading, advancing more than 0.15% on the day as global financial market participants focused attention squarely on the commencement of the two-day Federal Open Market Committee (FOMC) policy gathering later in the session. Fresh interest rate hike bets ahead of the central bank deliberations, coupled with energy-driven inflationary pressures and geopolitical friction, have provided strong underpinning for the currency.
Federal Reserve Outlook and Treasury Yield Pressures
Heading into the crucial monetary policy gathering, market pricing has increasingly reflected expectations that the US Federal Reserve will deliver an interest rate increase on Wednesday. Concurrently, heightened inflation concerns linked to elevated crude oil prices have kept US government bond yields pinned near multi-year peaks, presenting a persistent structural tailwind for the Greenback. Safe-haven flows have also gathered pace on the back of rising geopolitical confrontation between the United States and Iran, alongside maritime clashes reported in the Strait of Hormuz, prompting investors to seek defensive liquidity in the US currency.
Examining this evolving macro landscape, analysts at Danske Bank observed that US government yields have continued pushing higher, with the 10-year Treasury yield holding above the 5% threshold as investors recalibrate their interest rate expectations. Against this backdrop, the bank stated that it has revised its Fed call to anticipate a 25bp rate increase at Wednesday's meeting. Furthermore, Danske Bank indicated that it maintains its projection for additional 25bp increases at both the December and March gatherings, which would raise the terminal Fed Funds rate into a range of 4.25-4.50% by the end of 2027, compared with its previous estimate of 4.00-4.25%, confirming an increasingly hawkish trajectory.
Technical Indicators and Resistance Confluence
On the technical side, the Dollar Index is testing a critical confluence barrier around 99.80, represented by the 38.2% Fibonacci retracement of the decline recorded across July and August, lined up alongside the 100-day Simple Moving Average (SMA). While immediate overhead supply could trigger bouts of profit-taking near this threshold, a decisive close above it would open the door for an extension of the one-week-old recovery trend. Daily chart momentum oscillators have started validating this constructive technical structure.
Specifically, the Moving Average Convergence Divergence (MACD) histogram has crossed into slightly positive territory, while the 14-day Relative Strength Index (RSI) positioned around 54 signals strengthening upside momentum. A sustained push beyond the 99.80 area could see the index advance toward the 50.0% retracement level near 100.14 and subsequently challenge the 61.8% retracement at 100.50, before encountering stiffer chart resistance zones situated at 101.02 and 101.68. On the downside, primary technical support resides at the 23.6% Fibonacci retracement level around 99.33, followed by a deeper structural base at 98.60.
Live market data shows the US Dollar Index trading at 100.22, unchanged from the previous close of 100.22 (+0.00%). Over the trailing 52 weeks, the index has traded between 95.55 and 101.80, with trading volume matching its 20-day average at 1.00x. The technical setup features an RSI(14) at 60 and a MACD reading of 0.05 against a signal line of -0.12 (histogram 0.18, signaling bullish alignment). The 20-day Exponential Moving Average (EMA) sits at 99.58, the 50-day EMA at 99.73, and the 200-day EMA at 99.30, while the 50-day SMA is 99.95 and the 200-day SMA is 99.15, highlighting a golden cross pattern with price in a broader uptrend. Bollinger Bands (20,2) span from 98.43 to 100.30 around a midpoint of 99.36. The Average Directional Index (ADX) stands at 27, signaling an active trend, while Stochastic indicators show the fast line at 83 and the signal line at 91. The 14-day Average True Range (ATR) is 0.44. Key operational levels show a pivot at 100.32, resistance levels at 100.46 (R1) and 100.71 (R2), and support points at 100.07 (S1) and 99.93 (S2), alongside 20-day support near 98.56 and resistance near 100.56.
Performance Against Major Crosses
Across the broader currency board over the trailing 7-day period, the US Dollar registered broad-based strength against major counterparts, posting its most substantial gains against the New Zealand Dollar. Currency matrix calculations reveal consistent gains for the US unit as a base currency against high-beta and commodity-linked rivals, reflecting heightened risk aversion across financial markets.
Spillover Across Currency Pairs and Gold
The firm tone in the dollar has weighed significantly on key trading pairs and commodities. The Australian Dollar fell against the US currency, with AUD/USD languishing below 0.7150 during the Asian trading session on Tuesday, remaining pinned near its lowest level in more than three weeks. Elevated US bond yields and crude-driven inflation anxieties exerted downward pressure on the pair, while uneven August economic activity figures from China failed to provide meaningful support to the resource-tied Australian currency.
Concurrently, the USD/JPY pair advanced steadily toward the 155.00 threshold on Tuesday morning as foreign exchange participants monitored upcoming decisions from both the FOMC and the Bank of Japan (BoJ). Multi-year highs across US Treasury yields bolstered the pair, though market expectations of a potentially hawkish normalization path by the BoJ provided an underlying buffer for the Japanese Yen, possibly capping broader USD/JPY upside.
In the precious metals space, gold failed to sustain early Asian session gains, trading just beneath the $4,300 level. Bullion remained locked near a one-month low as investors reduced risk exposure and moved to the sidelines ahead of the Federal Reserve's policy verdict.
