FX Movers: US Dollar Leads as NZD, CHF and CAD Weaken

The US dollar was the clearest major FX gainer in the week ended 28 August 2026, supported by firmer Fed-rate expectations and a late-week rise in US yields after Jackson Hole commentary. Across the major currency board, the weakest moves showed up in the New Zealand dollar, Swiss franc and Canadian dollar, while the Australian dollar was comparatively steadier.

• Period covered: Monday 24 August to Friday 28 August 2026, using Friday-to-Friday closing levels where available.
• Main gainer: The US dollar strengthened broadly, with the dollar index reported on track for a nearly 0.9% weekly gain.
• Main losers: NZD, CHF and CAD were among the weaker major currencies against the US dollar.
• Key driver: Markets reacted to hawkish Federal Reserve commentary, higher US yield sensitivity and renewed geopolitical and trade concerns.
• Balanced takeaway: The week was less about one isolated currency story and more about broad USD demand returning into the end of August.

What Happened in FX This Week?

FX markets ended the final full week of August with a stronger US dollar tone. The move became clearer late in the week as investors reassessed the Federal Reserve outlook following Jackson Hole remarks and firmer US rate expectations. That helped lift the dollar against most major currencies, including the euro, pound, yen, Swiss franc, Canadian dollar and New Zealand dollar.

This weekly wrap focuses on measured currency movement rather than trade direction. For readers following forex markets, the key question is not simply which pair moved most, but what the pattern says about risk sentiment, yield expectations and relative currency pressure.

Weekly FX Movers: 24 to 28 August 2026

The table below summarises the major FX moves against the US dollar using available closing levels from Friday 21 August to Friday 28 August. Percentage changes are rounded and should be read as approximate weekly moves.

Why the US Dollar Strengthened

The main FX story was the return of US dollar demand. Reuters reported that the dollar was set for its strongest weekly gain in around 10 weeks after Federal Reserve Chair Kevin Warsh’s Jackson Hole comments increased market attention on the possibility of further tightening if inflation failed to cool. That shift lifted the dollar against the euro and yen late in the week.

For currency markets, this matters because the US dollar often responds to changes in relative interest-rate expectations. When investors believe US rates may stay higher for longer, or rise further, the dollar can attract support relative to currencies where central-bank expectations look less forceful.

This is also why the week had a broad feel. The move was not limited to one currency pair. EUR/USD fell, GBP/USD weakened, USD/JPY rose, USD/CHF rose and USD/CAD moved higher. That kind of pattern usually points to a wider dollar story rather than a single-country event.

Where Weakness Showed Up Most Clearly

NZD Was the Weakest Major in the Group

The New Zealand dollar fell from around 0.5977 against the US dollar on 21 August to about 0.5913 by 28 August. That left NZD/USD down roughly 1.1% for the week. The move came even as markets looked ahead to the Reserve Bank of New Zealand, with global dollar strength taking the lead in the short-term price action.

CHF Lost Ground as USD/CHF Rose

The Swiss franc also weakened, with USD/CHF rising from about 0.8011 to 0.8094 over the week. In simple terms, a higher USD/CHF rate means one US dollar bought more Swiss francs by the end of the week. That left the franc down about 1.0% against the dollar.

CAD Was Pressured by Trade Headlines

The Canadian dollar was another notable loser. USD/CAD rose from about 1.3767 on 21 August to about 1.3905 on 28 August. Reuters linked the loonie’s weakness to hawkish Fed commentary and investor doubts about whether strong Canadian GDP data would alter the Bank of Canada policy outlook. Earlier in the week, US-Canada tariff headlines also weighed on CAD sentiment.

EUR, GBP and JPY Also Slipped

The euro moved lower against the dollar, with EUR/USD falling from about 1.1679 to 1.1585 across the week. Sterling also softened, with GBP/USD falling from about 1.3634 to 1.3535. Reuters noted that the pound was headed for its first weekly decline against the dollar in more than a month as expectations for a Bank of England rate hike this year receded.

The Japanese yen also weakened, with USD/JPY rising from about 158.95 to 160.07. That kept the yen near levels that have repeatedly drawn market attention this year, especially after earlier intervention-related volatility. For traders watching risk sentiment, the yen remains important because it can respond to both Japanese policy expectations and broader global funding conditions.

AUD Was Comparatively Steadier

The Australian dollar was not strong in absolute terms, but it held up better than most of the majors covered here. AUD/USD slipped only slightly, from about 0.7172 to 0.7162 over the week. That made it one of the more resilient major currencies against the stronger US dollar backdrop.

This relative resilience matters because the Australian dollar is often watched as a proxy for global growth expectations, China-sensitive sentiment and commodity-linked risk appetite. In this week’s data, however, the stronger dollar story still dominated the broader FX board.

What Changed From the Prior Week?

The prior week had shown more mixed dollar trading, with several currencies holding firmer ranges. By contrast, the week ended 28 August saw a cleaner dollar-positive pattern. The shift came as investors moved from mid-August consolidation into a late-month focus on central-bank signals, inflation risk and upcoming US labour-market data.

That change is useful for market context because weekly FX movers often show where attention has moved. In this case, attention shifted back toward US policy expectations and away from isolated regional stories.

What to Watch Next

The next major test for FX markets is whether the dollar’s late-August strength continues to be supported by data. US labour-market figures, ISM data and further central-bank communication are likely to shape how investors interpret the Fed path. In Europe, inflation readings remain important for the euro. In Canada, the Bank of Canada outlook and trade headlines remain relevant for CAD. In Japan, the yen remains sensitive to both Bank of Japan policy expectations and intervention-related language.

Balanced Takeaway

The week ended 28 August was a US dollar-led FX week. The clearest weakness was seen in NZD, CHF and CAD, while EUR, GBP and JPY also slipped. AUD was comparatively more stable, but still ended slightly lower against the dollar.

The main lesson from the week is that FX moves often become clearer when they are viewed as a group. When several major currencies weaken against the same base currency at the same time, the market is usually reacting to a broader driver. This week, that broader driver was renewed demand for the US dollar as investors reassessed the Fed outlook, US yields and late-month risk conditions.
