As U.S. Treasury yields climbed, with both the 2-year and 10-year yields rising 5–6 basis points, and oil prices surged nearly 5%, the U.S. dollar strengthened broadly, with traders following the shift toward higher yields and safe-haven demand.USDJPY: The pair continues to push to fresh four-year highs and is closing in on the 164.00 level. Above that, the next major upside target comes in near 164.50, a level last seen in the 1986 swing highs.USDCHF: The pair has climbed to its highest level since July 2025 and is now trading within a key resistance zone between 0.8170 and 0.8214. Also in focus is the 38.2% retracement of the decline from the January 2025 high at 0.82116. Today's high reached 0.8177.USDCAD: This is the one major pair that has not fully embraced the broad U.S. dollar rally. The pair is trading little changed on the day but remains above its nearly converged 100- and 200-hour moving averages near 1.4065. As long as the price holds above those key trend levels, the technical bias remains tilted to the upside.NZDUSD: The kiwi is one of the weakest major currencies today, falling about 0.70%. The decline has pushed the pair into a key support zone between 0.5765 and 0.5777, with the low reaching 0.5770. A sustained move below that area would increase downside momentum. Earlier today, sellers leaned against the 200-hour moving average near 0.5824, helping trigger the latest leg lower.AUDUSD: The Australian dollar is also under pressure, testing support between 0.6962 and 0.6978 after reaching a session low of 0.6968. A break below that zone would expose the pair to additional selling. Earlier in the session, buyers failed to push through the 38.2% retracement of the decline from the May high at 0.7022 (session high 0.7021), giving sellers the technical green light to regain control. The broader U.S. dollar rally has accelerated the move lower.In the video above, I break down each of these currency pairs, highlighting the key technical levels that matter most and explaining why they are important. Successful trading starts with identifying the bias, defining the risk, and understanding the targets before entering a trade. This article was written by Greg Michalowski at investinglive.com.
