Has the Dollar Peaked?Dollar Index BasketFX:USDOLLARRymondIncThe dollar index sits at roughly 101.2 on Monday, barely moved from Friday but still riding the tailwinds of a more-than-one-year high it touched last week. The greenback is up over 2% in the past month and nearly 4.6% over the past year. For a currency that practically every major bank expected to weaken this year, that's not a drift. That's a reversal — and it leaves one question hanging over every trading desk right now: is this rally done, or just getting its breath back? Start with how we got here, because the size of the reversal is what makes the question worth asking at all. Rewind to January. Goldman Sachs, JPMorgan and MUFG all leaned bearish on the dollar, with some houses pointing toward a DXY somewhere in the low 90s by now. Every one of those calls rested on a single assumption: the Federal Reserve would keep cutting rates. Then inflation came back above 4%, and that assumption stopped holding. Two things did the damage, per Cambridge Currencies' read on the move First, the energy shock from the Iran conflict pushed headline US inflation to 4.2% in May, the fastest pace since April 2023 and the third straight month of acceleration. Energy prices alone jumped 23.5% year-over-year as the war disrupted shipping through the Strait of Hormuz, with gasoline up more than 40%. Second, Kevin Warsh's debut as Fed chair on June 17 turned out to be the more consequential of the two. Warsh is an unusual pick for the job — a former Morgan Stanley dealmaker who already served a stint as the youngest Fed governor in modern history before returning now as the institution's 17th chair, confirmed by the Senate on May 13 and sworn in nine days later. The Fed held rates at 3.50%-3.75%, as expected. What wasn't expected was the dot plot flipping from an implied cut to an implied hike, with the median policymaker now penciling in year-end rates of 3.8%, up from 3.4% back in March. The labor market gave the hawks more ammunition than the doves would have liked. May payrolls came in at 172,000 against expectations closer to 80,000, with combined upward revisions of roughly 93,000 added to the two prior months, while unemployment held steady at 4.3%. Wage growth, the one genuinely soft spot in the report, eased to 3.4%. Put a hot inflation print next to a labor market that refuses to crack, and you get exactly the kind of data that talks a committee out of cutting. If the dollar really has peaked, none of its usual victims have gotten the memo yet. Take the yen. It's sitting at roughly 161.850 per dollar, within a hair of the 40-year low near 162 set earlier this year. Japanese authorities intervened in the spring to slow the slide, just as they did in 2022 and 2024 — and just as in those earlier episodes, the intervention barely dented the trend. With markets now leaning toward a Fed hike rather than a cut, the yen needs something far more dramatic from the Bank of Japan than another bout of verbal warnings to stage a real comeback. The euro tells the same story. Wall Street has been quietly abandoning its bullish euro calls over the past few weeks, and the reasoning is almost identical to the yen story: the US looks set to keep raising rates while the European Central Bank no longer looks like it will. JPMorgan, Morgan Stanley and BNY Mellon now think the common currency could fall more than 3% to $1.10 over the next year. Morgan Stanley's currency strategists argue the move lower could happen quickly, as medium-term investors abandon their long-held bets against the dollar and momentum traders pile on once the trend is confirmed. BNY Mellon's Geoff Yu was a bit more measured, noting the European Central Bank's recent decision did the euro's case no favors given the growth hit it implies, while adding that his desk wouldn't aggressively chase a move below $1.10 even though it looks plausible. None of that reads like a market that thinks the dollar trade is over. Then came the number that really mattered to the Fed. The central bank's preferred inflation gauge, the PCE price index, climbed 4.1% year-over-year in May — also the fastest pace since the spring of 2023 — while core PCE, which strips out food and energy, hit 3.4%, its highest reading since October 2023. Part of that is the familiar energy story. And part of it is new: AI infrastructure spending is now showing up as its own inflationary force, as demand for data-center components, memory chips and the electricity to run it all outpaces supply. Micron's latest quarterly results, where revenue more than tripled on the back of AI memory demand, are as good an illustration of that dynamic as any. Minneapolis Fed president Neel Kashkari put a number on the shift, and his timing matters for the peak question specifically. In March, he had one rate cut penciled in for 2026. By late June, that had flipped to one hike, and he was explicit about why: persistent inflation in services, the build-out of AI data centers pushing up prices in anything that touches that sector, and a Middle East situation he isn't ready to call resolved. "I don't trust Iran to honor whatever agreement has been made," he said, pointing to overnight reports of violations of the ceasefire. He's far from the only voice on the committee shifting hawkish, but as a sitting voter on the FOMC this year, his pivot carries more weight than most — and a voting hawk who turned more hawkish in the last two weeks is not what peak-dollar usually looks like. Other markets have been telling the same story. Two-year Treasury yields, most sensitive to the Federal Reserve policy path, jumped sharply on the day of Warsh's first decision, touching their highest level in more than a year. Gold has paid the price for the dollar's strength on the other side of the ledger — spot prices broke below $4,000 an ounce for the first time since November 2025, a level that had looked untouchable just a few months earlier, before rebounding above it, where it's trading around $4045 an ounce. When yields, gold, and the dollar all move in the same hawkish direction at once, it's a reasonable signal that the repricing isn't confined to one corner of the market, which makes the case for "peaked" a harder one to make on fundamentals alone. So why is anyone still asking the question? Because positioning and price action are starting to tell a different story from the data. Robin Brooks, the former Goldman Sachs chief FX strategist who now writes a closely followed macro newsletter, has been making the contrarian case most loudly. His argument starts with a genuine puzzle: President Trump signed the framework to end the Iran war on the very same day the Fed delivered its hawkish surprise, June 17. Historically, de-escalation in that conflict has coincided with dollar weakness, as safe-haven flows reverse and risk appetite returns. That didn't happen this time, which Brooks reads as evidence that the Fed's hawkish signal overwhelmed what should have been a risk-on dollar selloff — and as a sign that markets are reaching for any excuse to stay long the currency rather than responding to genuinely new information. Looking at the CFTC's weekly Commitments of Traders data, he points out that speculative positioning is now about as one-sidedly long the dollar as it was during the 2012 eurozone debt crisis or the 2014 BoJ-ECB easing episode. Extreme positioning like that, in his view, tends to set up disappointment rather than confirm a trend — which is why he's calling this peak dollar, with a fall from here as the more likely path, especially as falling oil prices work their way into cooler inflation prints in the months ahead. There's a useful reason to take that kind of contrarian call seriously: nearly every major desk has been wrong-footed on this currency already this year, which should make everyone a little humble about calling the next leg with confidence. Goldman Sachs's own research, flagged in GoldSilver's coverage of the call, shows the bank went in with a clean bearish view — dubbed "different dollar downside" — built on the idea that demand for US assets would keep fading. That thesis cracked when Goldman itself pulled all of its 2026 rate-cut forecasts in June and pushed expected easing out to 2027, the same shift that broke the bearish-dollar case across most of the Street. J.P. Morgan's house strategists were more careful from the start, framing dollar strength as "quite bounded" while leaving more room on the downside — a smile-shaped view rather than a hard directional bet — and the bank's research notes show it upgraded its dollar outlook back in mid-May once labor data stabilized and the Fed's tone turned hawkish. Morgan Stanley's call, set out in its own currency research, was the most specific and arguably the most wrong-footed: deeper losses in the first half of 2026 with DXY sliding toward 94, followed by a climb back to 100 by year-end. The back half of that call has essentially shown up early. The front half — the H1 weakness — never really arrived. If the Street's own track record is the guide, the honest answer to "has it peaked" is that nobody currently calling it has earned the right to be fully confident either way. The charts, for what it's worth, are casting a tiebreaking vote toward "stretched." The daily RSI on the index has been parked in overbought territory near 74, which usually signals a move running out of steam even when the underlying trend remains intact. Resistance sits around 101.95-102, the high last seen in May 2025; support is layered underneath at 101.48, then the psychologically important 100 level, then a deeper floor near 98.5-99. That's the textbook setup for consolidation or a sharp pullback on the next disappointing data point, rather than a clean answer to the peak question one way or the other. So, has the dollar peaked? The fundamentals — a hawkish Fed, inflation that won't fully cooperate, a labor market refusing to soften — say not yet. The technicals and the positioning data say the move is tired and overcrowded, which is usually how peaks happen even when nobody can see them coming. Both things can be true at once, which is exactly why nobody serious is putting real conviction behind a top call right now. Whoever's still leaning the wrong way when the data finally turns will find out the answer faster than they'd like.
