Two Time Horizons in Dollar Behavior: Short-Term Repricing and Long-Term Reserve Diversification

Thesis: Over short time horizons, the dollar's value responds primarily to the magnitude of a surprise relative to prior expectations rather than to the direction of the underlying policy action itself wherein a single Fed appointment or labor market release can move the currency more than an actual rate change abroad. Over longer horizons, the dollar's share of global reserves has declined from roughly 70% to 57% over 25 years, with reserve managers forecasting a further move toward 50% within a decade. However the two mechanisms most often credited with this shift, central bank gold buying and BRICS-led de-dollarization do not hold up as its primary drivers on closer examination. The more accurate picture is a currency capable of significant short-term volatility alongside a slow largely uncoordinated decline in reserve status. These two distinct phenomena, on two distinct time horizons, frequently conflated as one.

I. The Recent Whiplash

The commencement of 2025, saw the beginning of a declining trend for the US Dollar Index. The index fell from its January 2025 peak above 109 to roughly 99 by May, then continued weakening through the summer, briefly touching the mid-96s in September before regaining momentum by year end. The dollar’s decline then continued into 2026, late January saw the Dollar Index (DXY) falling further below the key 100.00 baseline, and reached a near four-year low of 95.5, dating back to February 2022. The low landed in late January, came ahead of that month’s FOMC meeting, as markets priced in an expanding rate-cut path. However, through the first half of 2026 the dollar had staged a strong recovery, with the DXY reaching a 13-month high, up 3% since the start of the year and 5% since late January. Now, as of the second week of July, the DXY closed at 100.908 on July 7th up 3.48% over the trailing 12 months, over that same 52-week window, DXY ranged from 95.55 to 101.8. The proximate cause rests in a few nuanced factors, analysts broadly agree the Fed has been the main catalyst behind the reversal and appreciating strength. At the June 17th meeting, Kevin Warsh’s first as chair, the Fed held rates at 3.50% - 3.75%. Wherein the market priced in a hawkish, higher-for-longer, path forward and the probability of future rate hikes, given a consistently rising and accelerating inflationary backdrop from January’s 3.09% Core PCE YOY to May’s 3.41% YOY. The rising inflationary data, mostly still attributed due to the energy shock from the Iran conflict, and expected Fed action provided a positive sentiment for the dollar’s strength. The dollar remains roughly 15% overvalued relative to major peers on a purchasing power parity basis, according to RBC Global Asset Management estimates, with analysts framing current strength as cyclical through rate differentials and risk premium rather than a genuine shift in fair value.

The Fed’s June stance however, has now been challenged by a pullback complication in the June jobs report. Nonfarm payrolls were +57,000 vs 113-115K consensus (BLS, released July 2, 2026). Furthermore May and April were revised a combined 74,000 lower. The unemployment rate decreased from 4.3% May to 4.2% in June, still healthily in line with natural unemployment, however in reality the drop was driven by a falling participation rate to 61.5%. The lowest participation rate since March 2021, showing the shift did not embody job creation. Futures markets (via CME’s Fedwatch) priced roughly even odds of a September hike, down from about two-thirds odds before the report; the 2-year treasury yield also fell by 3.5 basis points.

II. The Fast Clock: What is actually moving FX

The cyclical nature of the Whiplash effect detailed in Section 1, indicates just how much FX can turn on one appointment, a feature of how fast and liquid the market is, not necessarily based on structural changes. January 2026, saw markets pricing the probability of yet another rate cut, by late spring into summer that story had changed. In 2025 inflation measured through Core PCE was sticky, above the Fed’s 2% benchmark. However, from December 2025 to May 2026, the index had risen from 2.97% YOY inflation to 3.41%, furthermore labor has not shown convincing evidence of softening or cracking. Markets began pricing in a Hawkish Fed narrative, as they held at 3.50-3.75% on June 17th but delivered a hawkish dot plot. This came amidst a similar reaction from other central banks. The ECB hiked its deposit rate to 2.25% on June 11th, citing inflationary pressures from the Middle-East conflict, with headline inflation projected at 3.0%. The BoJ similarly hiked to 1.00% on June 16th, the highest since 1995, as it continues its normalization path. In relative terms the Fed did not “out-hike” either the ECB or BoJ, rather, it “out-hawked” them on expected policy path. 

The dollar rallied not because US Rates rose in absolute terms but because the market’s expectations shifted more on the US side than on the European or Japanese side, despite those central banks actually hiking. Once again this underpins that FX prices react to the size of the surprise relative to expectations, not the direction or magnitude of the actual policy action in the short-term. This is furthermore evident from the June job report, with no specific policy change at all, just print data which was enough to erase 15% of the priced-in odds for a September hike, no action but simple repricing mechanics. Of course, none of this happened in a vacuum: the dollar retains a substantial yield advantage over both the euro and yen, which is why the market had a clear direction to reprice toward once expectations shifted. Furthermore, economic growth has slowed since earlier cycles, where GDP growth was 1.4% and 1.6% in Q4 2025 and Q1 2026 respectively. The economy has been in expansionary territory in both manufacturing and services, but real growth has come at a slower pace than Q2 and Q3 2025. GDP growth acceleration isn’t necessarily what is broadly pulling capital in, though it is relative on a country by country basis of course. This comes amidst relatively loose financial conditions with the Chicago Fed's National Financial Conditions Index (NFCI) hovering around -0.50 for a majority of the year. Furthermore, there is a real appetite for risk in US markets despite geo-political instability, high-yield credit spreads (HY OAS) ranged between 2.83 in January, a peak of 3.46 in March, and July now back down to 2.71. Between a yield advantage that predates the move, growth that isn't firmly accelerating, and risk appetite that stayed firm throughout, the case for anything other than repriced expectations driving the June rally is thin.

III. The Slow Clock: What Central Banks Are Actually Doing (De-dollarization, Gold, and Alternative Currencies)

While Section II outlines the dollar’s short term fluctuations based on weekly / monthly economic triggers. Section III seeks to outline a different mechanism running underneath it, a gold-buying baseline and alternative currency diversification. From 2022 - 2025 central banks have averaged 1,000 tonnes/year in net gold purchases, a figure which is roughly double the 500 tonnes/year average of the prior decade. 2025 came in at 863 tonnes, while still technically below the 1,000t + mark hit in the three prior years, it still remains historically elevated. The World Gold Council (WGC) frames this as moderation, explicitly, and not a reversal. Q1 of 2026 saw purchases net 244 tonnes, a 17% increase over the prior quarter, the deceleration story has and is not holding into 2026. May alone saw +41 tonnes, led by Poland (18t), China (10t): while Turkiye and Russia were net sellers (-3t and -6t) respectively. Poland is a standout, with 64 tonnes accumulated year-to-date through May of 2026, a fourth straight month of double digit purchases. Governor Adam Glapinski of Poland has publicly stated a further intent, to keep raising said reserves toward a stated 700 tonne target. While China, Uzbekistan, and Kazakhstan are in a steady and repeated accumulation phase, furthermore Singapore has rejoined buyers in May after a pause since September 2025. This accumulation trend is consistent with reserve managers’ own stated intent. The WGC’s 2026 Central Bank Gold Reserves survey (Feb 5th - May 19th, 2026) had 76 respondents, the highest participation in the survey’s 9-year history, while 89% expected global central bank gold holdings to rise furthermore over the next 12 months. 

The intent to keep buying outpaces even the record purchases already underway suggests this isn't a trend running out of momentum, reserve managers are, by their own account, still early in this reallocation. This distinction is now showing up in the composition of reserves themselves. Gold has now surpassed Treasuries as a share of central bank reserve holdings, a real and structural milestone. While the dollar’s share of global FX reserves has fallen from roughly 70% to 57% over the past 25 years, and according to the OMFIF’s 2026 Global Public Investor survey, for the first time more central banks are planning to reduce dollar exposure over the next decade than increase it, reserve managers’ own average 10-year forecast puts the dollar’s share at around 50%.

Now the question becomes, is this general and modest reserved diversification or a targeted campaign to cut dollar exposure specifically, and are there exceptions? Well it’s important to distinguish between who is actually driving the shift versus those countries which are simply diversifying. So far Russia, China, and Turkiye alone have accounted for 64% of all gold reserve accumulation since 2008. It's important to note these countries' BRICS affiliations, two of which – China and Russia — are founding BRICS members, while Turkiye is a registered partner country. Russia’s dollar share has collapsed from 70% to under 20% between 2006 and early 2022 (large declines driven by post-2022 sanctions), Turkiye’s from 77% to 30% between 2016 and 2018, and China’s from 79% to 55% over the past two decades. These are clear cut instances of de-dollarization, wherein the country’s dollar reserves fell meaningfully as its gold reserve share rose, though it may not be so simple. 

Outside these three countries, the pattern largely doesn’t hold, in some cases running the opposite way. Poland’s gold buying habits outlined earlier, saw its own dollar reserve share rise from a 38% average five years ago, before its rapid gold accumulation in 2017, to 41% in 2023. Brazil (a founding BRICS member may I add) has settled more than $100 billion in local currencies through its annual bilateral trade with China. Yet their dollar share has stayed essentially flat, at 82%, even across a decade of gold purchases 2011 to 2021, undercutting evidence of any clean “BRICS is exiting the dollar” narrative. In 2025 a Federal Reserve study, headed by Colin Weiss found no statistically significant relationship between a country selling U.S. assets and buying gold reserves across 2012 - 2023 (Federal Reserve Board International Finance Discussion Paper No. 1420 (September 2025). Furthermore after 2021 the relationship flipped positive where countries buying more gold also bought more U.S. assets. Weiss’s paper references Douglass, Goldberg, and Hannaoui’s 2024 NY Fed paper, “Taking Stock: Dollar Assets, Gold, and Official Foreign Exchange Reserves,” in which the precise finding is that countries with weaker geopolitical ties to the U.S. have accumulated more gold and per Weiss's own data, many of these same countries continued buying US assets after 2021 (measured by UN voting alignment through regression analysis). So it's not "gold instead of dollars" even among the more geopolitically distant buyers, it's often both at once, a fact opposite of what a coordinated de-dollarization campaign would predict. For most gold buyers, this looks like general portfolio diversification, not a targeted undermining of dollar exposure. 

Weiss’s paper is instrumental in a few regards, by mostly debunking the headline assumption that gold purchases equate to declining dollar reserve share. The dollar’s declining share isn’t going to gold or to a rival bloc’s currency, rather it’s dispersing into a wider basket of smaller, liquid currencies that didn’t operate as credible reserve options a generation ago. Gold’s share of official international reserves was 9% in 2008 to 16% in 2024, there is real growth but it’s still largely dwarfed by the dollar’s 57% of FX reserves. Arslanalp, Eichengreen, and Simpson-Bell’s 2022 IMF working paper, "The Stealth Erosion of Dollar Dominance,” found that 75% of the shift out of dollars went into the AUD, CAD, KRW, SGD and similar currencies, while 25% went into the renminbi. The euro, yen, and pound gained no share. Their core finding: the decline in the dollar's reserve share since 1999 is real, but it is active diversification by reserve managers and not a statistical artifact driven by exchange rate/valuation effects, and not driven by a handful of outlier central banks. Just to note quickly on that diversification, Arslanalp, Eichengreen, and Simpson-Bell’s paper explicitly frame reserve managers as weighing a country’s issuing economy size, financial market depth, as well as their ability to hold value. The Australian dollar, Canadian dollar, Korean won, and Singapore dollar simply did not have deep enough bond markets or hedging infrastructure some 25 years ago, to be viable reserve assets at scale. A fact which has changed. Furthermore as more central banks continue to hold these currencies, liquidity in them deepened further. A self-reinforcing gradual process, rather than a single trigger event, therefore the evidence for increased reserve share of these currencies comes as a 25 year drift. 

That gradual, infrastructure-driven story is easy to conflate with a louder one: the idea that BRICS itself is engineering the dollar's exit. The two get treated as the same phenomenon, but they aren't and it's worth checking what the bloc has actually committed to in writing, rather than what's assumed about it. A quick Google search about BRICS intended goals will yield phrases such as “de-dollarization, institutional reform, and reducing reliance on Western financial systems,” and this paper has already presented both supporting and undermining evidence of such through China, Russia, Turkiye, and the outlier Brazil. The evidence of BRICS being a genuine driver of de-dollarization is mixed, with real claims but at times a lacking concrete substance. A lack of structural evidence at least in terms of current de-dollarization trends and the West’s headline fears, perhaps however it is a future worrisome engine, one that is still being stoked with fuel. De-dollarization has been an explicit, named goal of the bloc since the 2023 South Africa summit and subsequent summits have produced real institutional steps. The Kazan declaration in 2024 tasked further investment into a BRICS cross-border payment initiative, through a dollar-free securities settlement system known as BRICS Clear and expanded currency swap arrangements between member central banks. China and Russia appear to be the motivated core behind this initiative, as seen through their tangible de-dollarization and gold purchasing history, whether that be to blunt sanctions or internationalize their own currencies.

But countervailing evidence is also strong, wherein each summit has fallen short of an ambitious rhetoric. For example, a common BRICS currency and rumored “petro-yuan” were reportedly floated at Kazan and never adopted. BRICS Clear was studied, but not implemented and by the 2025 Rio summit the general dialogue had receded with no mention of a common currency or coordinated dollar-reduction strategy in text. India, its current chair, and the UAE which remains formally pegged to the dollar have been sources of resistance on this matter. India’s foreign minister, S. Jaishankar has stated quite plainly that the country has no policy to replace the dollar, as mentioned in this quote while speaking at the Chatham House in London, March 2025 he stated: “I don't think there's any policy on our part to replace the dollar... I don't think there's a unified BRICS position on this. I think BRICS members and now that we have more members have very diverse positions on this matter. So the suggestion or the assumption that somewhere there is a united BRICS position against the dollar I think is not borne out by facts." Structurally, a majority of the local currency swap lines that do exist run almost exclusively through the Chinese renminbi, via the People’s Bank of China, making this effort seem less multilateral and more as if a China-centered effort. Even from the de-dollarization evidence mentioned earlier, the reserve data doesn’t implicate BRICS currencies at all. Whereas three-quarters of the actual shift out of the dollar reserves over the past 25 years went into the Australian Dollar, Canadian Dollar, Korean Won, and Singapore Dollar which are economies aligned with the existing dollar system rather than the BRICS bloc’s intended goals.

Weighing both sides of the argument, a defensible read is that BRICS has been a vocal advocate for de-dollarization but not yet its primary engine. In reality the dollar’s reserve share falling from 70% to 57% over the past 25 years has appeared to be driven by ordinary uncoordinated diversification by individual reserve managers. Though, as stated coming concurrently with BRICS’s two most motivated members China and Russia contributing genuine and measurable de-dollarization of their own reserves, but not a collective binding BRICS action. The predicted drop of 57% to 50% dollar reserve shares, remains an open question rather than a settled trend. Evidence across the past few years does indicate a continuity of the current pattern with individual member action outpacing collective commitment.

IV. Conclusion

Section I’s Whiplash, Section II’s Fast Clock, and Section III’s Slow Clock are not competing explanations of the same phenomenon, they are two different processes which are operating on two different clocks. There is no reason both cannot be true simultaneously. The dollar can still rally 6% in five months on a single Fed appointment all while its reserve shares drifts slowly downward across 25 years for a simple fact. Nothing in the current financial system has replaced the dollar’s role as the deepest and most liquid asset available when markets want to move fast. Reserve diversification into the Australian dollar, the Korean won, or even gold is a decision made over years, sized in the hundreds of billions. It does not and structurally furthermore cannot absorb the kind of rapid large-scale capital flows that a hawkish dot plot or weak jobs report can trigger in a single week. The fast clock exists precisely because the slow clock hasn’t produced an alternative liquid enough to compete with it yet. 

This has a practical implication worth stating plainly, most headlines about the dollar are, actually headlines about one clock or the other, and conflating them produces bad analysis in both directions. A story about the DXY's weekly move is a fast-clock story wherein it says something about Fed communication, data surprises, and rate differentials, and essentially nothing about the dollar's long-run structural position. A story about central bank gold buying or a BRICS summit is a slow-clock story and, per Section III, even those often overstate the pace and coordination of what's actually happening. Recognizing which clock a given piece of news belongs to is the difference between treating a single data print as evidence of a structural shift, and correctly reading it as one more entry in a currency's ordinary, fast-moving weekly repricing.
