US Dollar Rallies as Tariff Tensions Rattle Markets and Risk Appetite

feature image

Tariff headlines have returned to centre stage, with President Trump warning key trade partners that high tariffs will be implemented on 1 August if trade deals are not reached. His letters also threatened to increase tariffs should trade partners raise theirs on the US. While this provides just over three weeks to strike deals – which could turn out to be a good thing – it serves as a reminder that Trump means business, literally.

Tariff Pressures Boost US Dollar as Wall Street Pulls Back

Wall Street indices faltered, with the S&P 500 and Nasdaq 100 falling around -0.9% from their record highs set on Friday. Dow Jones futures also fell -0.9%, forming a bearish engulfing day and gapping lower at today’s open alongside the S&P 500 and Nasdaq 100 futures markets.
 
The US dollar (USD) was the strongest of the major currencies, as the return of tariff threats revived fears of inflation and a constrained Federal Reserve (Fed) that may be unable to cut interest rates. The US dollar index rose for a fourth consecutive day, gaining 0.4% to reach a seven-day high.

 

Major FX Moves: USD Strengthens Across the Board Amid Tariff Tensions

EUR/USD, GBP/USD, AUD/USD, and NZD/USD show bearish engulfing or reversal candles. USD/JPY rallies, USD/CAD holds a higher low, and USD/CHF stabilises above its head and shoulders target. Annotation notes the USD was the strongest major on Monday, driven by renewed inflationary fears due to tariff threats.

  • The Japanese yen (JPY) and New Zealand dollar (NZD) were the joint weakest major currencies, with USD/JPY rising 1.1% and NZD/USD falling by the same amount.
  • Commodity currencies were broadly lower, with the Canadian dollar (CAD) and Australian dollar (AUD) also coming under pressure — sending USD/CAD up 0.6% and AUD/USD down 0.9%.
  • The stronger US dollar and renewed tariff threats have allowed AUD/USD bears to refocus on potential RBA rate cuts, with the first expected today (read my preview for a full rundown).
  • The euro (EUR/USD) fell 0.6% and formed a bearish engulfing candle. While support was found at the October high near 1.17, a break beneath this level would signal a deeper pullback for the euro — and further upside for the US dollar index.
  • The British pound (GBP/USD) also printed a bearish engulfing day, keeping a move towards the June VPOC (1.3550) in play. A break beneath that level would bring the 2024 high at 1.3434 into focus.
  • The Swiss franc (CHF) weakened alongside the yen, although safe-haven flows limited the damage. USD/CHF rose 0.5%, compared to the 0.9% gain seen on USD/JPY.

US Dollar Index (DXY) Technical Analysis

The US dollar index is undergoing its most bearish decline since the pandemic, having fallen over 12% from the January high to last week’s low. But with prices holding above the 2023 low and Trump’s tariffs back in focus, a bullish case — even if only temporary — is starting to form for the US dollar.

The weekly DXY chart shows a small bullish pinbar that marked a false break beneath the 2023 low, suggesting an interim swing low may be in place. A bullish divergence has emerged on the RSI (2) after touching oversold territory in both April and May. A more subtle bullish divergence has also formed on the weekly RSI (14), hinting at waning bearish momentum.

I’m now on alert for a bounce toward the 10-week EMA (98.28) or the 99.00 handle near the bearish engulfing candle’s high. Should that bounce materialise, we can reassess the likelihood of a deeper recovery or whether the dominant bearish trend resumes.

A break below last week’s low would invalidate the short-term bullish case and open the door toward the high-volume node (HVN) around 91.74 — a move that assumes continued softening of US data and an increased likelihood of Fed rate cuts.

A bullish pinbar has formed above the 2023 low, with bullish divergences appearing on the RSI (2) and RSI (14). Technical levels highlighted include the 10-week EMA at 98.28, resistance near 99.00, and a downside target at the high-volume node (HVN) around 91.74.

US Dollar Index (DXY) Daily Chart

The US dollar index came close enough to the downside head and shoulders (H&S) target at 95.73 to call it a success. Prices have now risen for four consecutive days, and the dollar could extend those gains if tariffs remain elevated for some US trade partners.

That said, the daily RSI (2) reached its most overbought level since 21 March on Monday, and prices closed on the April low. A bearish trendline also resides around the 98 handle, making it a potential resistance area for bulls to target or for bears to consider reloading around.

Prices have risen four sessions in a row and now test resistance near the April low and bearish trendline. The RSI (2) reached its most overbought level since March, hinting at a short-term exhaustion point. Labels mark the H&S structure with “Head,” “LS,” and “RS,” and an annotation highlights potential resistance zones near 98 and 99 as areas for bullish targets or bearish re-entry.
