In the early days of 2025, the U.S. dollar index experienced a notable uptick followed by a subsequent pullback, igniting fresh discussions regarding its long-term trajectoryA recent report from Morgan Stanley reinvoked the narrative of a “2017 dollar downtrend playbook,” drawing parallels between the current market environment and historical contexts from eight years priorThe report posits that three primary factors – a easing stance on trade policies, synchronized global economic growth, and a reduction in European political risks – could propel the dollar into a phase of depreciation.

Peering back to the dollar's performance in 2017 reveals that the dollar index nosedived by 9.85%, marking it as the worst year for the currency from 2004 to 2024. This downturn was chiefly fueled by three pivotal elements: the initial noise surrounding tariff policies from the U.S. government turned out to be more of a negotiating tactic than concrete action, whereby the actual trade restrictions implemented fell significantly short of market expectations

Additionally, during that time, the global economy experienced a “synchronized recovery”, with the Eurozone’s growth outpacing that of the United States, lending strength to the euroLastly, the election of Emmanuel Macron as the French president mitigated fears surrounding the fragmentation of European politics, dissipating concerns regarding a possible Eurozone dissolutionThese combined pressures culminated in the dollar relinquishing its safe-haven premium and triggering a trend of devaluation.

The present market environment shares striking similarities with 2017. With respect to trade policies, the threats posed by the new U.S. administration regarding “reciprocal tariffs” seem to act more as a strategy for negotiation rather than indicating actionable consequencesA Morgan Stanley survey reveals that 30% to 40% of investors are of the belief that tariffs will not genuinely be enacted but will instead serve as leverage in discussionsThis softening of policy expectations directly diminishes the dollar’s appeal as a safe havenFurthermore, data shows that U.S. real imports are anticipated to rise by 6.2% in 2024, implying that the concern over tariffs has yet to create a significant impact on trade volume.

The evolving dynamics of the global economic landscape lend further credence to the narrative of a weakening dollarThe latest International Monetary Fund (IMF) report has upgraded the global economic growth forecast for 2025 from 3.1% to 3.5%, with the Eurozone’s growth rate being adjusted from 1.2% to 1.8%. Such growth differentiation, characterized by a slowing U.S. economy juxtaposed against a speeding up of non-U.S. economies, mirrors the scenarios emergent in 2017.

A marginal improvement in European political risk represents an additional pressure point contributing to the dollar's decline

In 2025, Germany’s coalition government is set to unveil a “New Industrial Strategy,” planning a staggering investment of €500 billion over five years to bolster green technology and digital infrastructureThis infusion of policy certitude is expected to steepen the Eurozone’s long-term bond yield curve, causing the yield on the 10-year German bund to rise from the 2024 nadir of 1.2% to 1.8%, thereby reducing the yield spread relative to U.STreasuries by 250 basis points and creating a valuation recovery tailwind for the euro.

Technical analysis indicates that the dollar index is facing critical resistanceOn the monthly chart, the dollar index is encountering significant resistance around the 110 level, which marks the high point of 2022, with the relative strength index (RSI) demonstrating a bearish divergence, suggesting waning bullish momentumA drop below the 200-month moving average at 106.50 could potentially open the door for further declines toward the 102.00 level, the low of 2018. In contrast, the euro/dollar is forming a double bottom around the 1.0400 mark and could achieve a target of 1.0850 (the high for 2024) if it manages to breach the neckline at 1.0600.

Moreover, the divergence in economic fundamentals reinforces the forecast of a weakened dollar outlookThe core PCE price index in the U.S. is projected to rise by 2.8% y/y in 2024, falling short of the market’s expectations of 3.1%, which demonstrates sustained easing of inflation pressuresThe Federal Reserve’s dot plot indicates two expected interest rate cuts in 2025, while the European Central Bank has maintained its hawkish stance owing to persistent inflation

This disparity in monetary policies has led to Eurozone real interest rates (at -0.5%) surpassing those in the United States (-1.2%) for the first time, altering the direction of cross-asset arbitrage opportunities.

Market sentiment is also a crucial aspect to considerAccording to CFTC data, speculative positions on the dollar have diminished significantly, with net long positions plummeting from 185,000 in December 2024 to just 52,000, marking the lowest level since 2023. Moreover, the world's largest currency hedge fund, Brevan Howard, has ramped up its net short position on the dollar to $8 billion, reaching new heights not seen since 2021. Such shifts in “smart money” often herald imminent turning points in market trends.

However, there remain foundational support factors for the dollar's long-term standingFirst and foremost, the United States’ technological supremacy persists, with semiconductor exports projected to surge by 14% in 2024 and AI-related patent applications accounting for an impressive 42% of global totalsSecondly, the dollar continues to secure a stable foothold in the global payment system, comprising around 40% of worldwide transactionsFinally, the success of America's energy independence strategy is evident, with the net crude oil exports hitting a record 3.2 million barrels per day in 2024 and the current account deficit shrinking to 2.1% of GDP.

In conclusion, while the dollar is poised to face more depreciation pressures than appreciation drivers in 2025, its significant decline is likely to be constrained by its status as a global reserve currency

Morgan Stanley anticipates that the dollar index may descend to the 98-100 range by year-end, with the euro/dollar climbing to 1.08-1.10 and the pound/dollar reaching 1.28-1.30. Investors might consider constructing an arbitrage portfolio by purchasing euro/dollar call options (strike price of 1.08, six-month duration) and dollar/yen put options (strike price of 108), while allocating towards a gold ETF (target allocation of 5%) as a hedgeThe upcoming G7 finance ministers' meeting and Federal Reserve’s monetary policy gathering in the next three months will serve as pivotal intervals — any signals of a policy shift could precipitate considerable market volatility.
