US Dollar Index Breaks Key Technical Level, Hits Highest Since April 2025
nashnova research
The dollar index broke above its 200-week moving average to the highest level since April 2025, driven by a triple alignment of technicals, fundamentals, and capital flows — but MUFG warns the strongest pillar, record foreign inflows, could itself become the biggest risk.
What are the technicals saying?
DXY has reclaimed the 200-week moving average; the 200-day MA keeps tilting higher; the RSI — a gauge of momentum strength — has not yet entered overbought territory.
This means → bullish signals are fully lit, with the next major resistance at the trendline near 105. Until that level, there is still room to run.
Refinitiv data shows the current pattern closely mirrors late 2021 — when the dollar launched a significant rally from a similar setup. Put simply = the chart "looks like" the eve of the last big move up.
What fundamentals are holding the dollar up?
The Citi Economic Surprise Index shows U.S. data broadly beating expectations; the dollar's moves remain highly correlated with relative yield differentials.
This means → as long as America's interest-rate advantage over other economies does not narrow materially, the dollar retains fundamental support.
The eurozone tells the opposite story: EUR/USD has fallen below its 200-day MA, with an initial downside target at 1.10. A sharp drop in energy prices and hawkish ECB signals both failed to lift the euro; France's fiscal risks are adding to the pressure.
How strong are the capital flows?
In the year to August, foreign investors bought a record $1.47 trillion in U.S. equities and corporate bonds — nearly double the pre-GFC peak.
Because FX hedging — using derivatives to lock in exchange rates and reduce currency risk after buying dollar assets — ratios remain low, these inflows translate directly into dollar demand.
Speculative positioning confirms the trend: leveraged-fund dollar longs hit the highest since early August; euro shorts reached one of the most extreme levels since March 2020.
Why could the strongest pillar become the biggest risk?
MUFG warns that if U.S. equities underperform global markets on a sustained basis, foreign appetite for American assets could cool, eroding the capital-flow pillar under the dollar.
In plain terms = record foreign inflows are the dollar's most powerful engine — but a single-engine plane has a single point of failure. If it stalls, the reversal is just as violent.
This reflects a critical nuance: the dollar does not need foreigners to dump U.S. assets to weaken. If they simply raise their FX hedge ratios, that alone can significantly shift supply-demand dynamics in currency markets.
Where will the trigger for the next reversal come from?
MUFG sees relative U.S. equity performance and changes in foreign positioning as the two key indicators for whether dollar strength can last.
This means → the signal for the next dollar trend reversal will most likely appear in U.S. stocks first, not in the FX market itself.
Put simply = to judge when the dollar peaks, watch equities, not the exchange rate.
