NextFin News - Currency carry trades are enjoying their best run in more than two decades, with G10 carry strategies returning around 8% so far in 2026 and emerging-market carry gauges climbing about 17% — their strongest performance since 2009 — as investors borrow in cheap currencies like the yen and euro to chase higher yields abroad. The setup is working beautifully. That is exactly why it should make investors nervous.
The trade has become the defining alpha engine of 2026: wide interest-rate gaps between the world's major economies, a dollar that has stopped climbing, and foreign-exchange volatility that has fallen to multi-year lows. Hedge funds are leaning in — net short positions against the Japanese yen have reached their largest size since 2007, Commodity Futures Trading Commission data show. Goldman Sachs Group Inc. says the backdrop for G10 carry strategies is the most compelling since 2000. But the same conditions that are feeding the gains are also loading the risk: carry trades accumulate profits slowly and lose them fast, and the last time this particular unwind happened — August 2024 — it did not stay in the currency market.
The Setup: Why Carry Is Working Now
The mechanics of a carry trade are simple enough that their persistence is what deserves attention. Borrow where money is cheap. Invest where it pays more. Pocket the difference. The strategy only works if exchange rates stay quiet — a currency move of a few percent can wipe out a year's worth of yield pickup for an unhedged position — which is why the current environment is so unusual. Emerging-market currencies have exhibited lower volatility than G7 currencies for nearly 200 consecutive days, a streak that would be the longest since 2000 if it holds, according to JPMorgan volatility indexes. One-month implied volatility on the Bloomberg Dollar Spot Index has sunk to its lowest level since December.
The yield gaps doing the heavy lifting are the widest in the developed world in years. U.S. two-year Treasury yields remain above 4%, compared with roughly 2.6% in Germany, 1.4% in Japan, and close to zero in Switzerland. That dispersion is not an accident of one central bank's policy — it is the product of a global divergence. The Federal Reserve has held its benchmark rate in the 3.50%-3.75% range for five consecutive meetings, most recently in July, even as three FOMC members dissented in favor of a 25-basis-point hike. The European Central Bank, by contrast, raised its deposit rate to 2.25% in June. Japan's benchmark sits at 1% after the Bank of Japan's June increase, the highest since 1995 — still far enough below the rest of the G7 to keep the yen the world's favorite funding currency.
The yen is doing the bulk of the work. USD/JPY broke above 162 on June 30, the weakest the yen has been since December 1986, and hedge funds' net short position against it reached roughly 146,000 contracts as of June 30 — the most bearish reading since 2007. The yen has now posted four consecutive quarterly losses, its longest losing streak in four years, despite Japan deploying about $74 billion in currency intervention between late April and late May. The market, in other words, is calling Tokyo's bluff.
But the dollar itself has also become a funding currency of choice — a notable shift. With the Fed's rate path looking increasingly stable and the dollar's one-month implied volatility near its lowest since December, traders are borrowing in dollars to buy higher-yielding assets in developing nations. Capital inflows into emerging-market assets have accelerated across 2025 and into 2026, reaching the fastest pace since 2019 by various measures. The MSCI Emerging Market Currency Index hit a record in July and is on track for its best year since 2017, up more than 6%. Mexico's peso and Brazil's real are among the best performers, backed by high local rates — Brazil's benchmark is at a two-decade high of 15%.
"Betting on carry bears more relevance in the Group of 10 foreign-exchange space than at almost any point since 2000," Stuart Jenkins, a strategist at Goldman Sachs, wrote in a July report. The bank favors the yen, Swiss franc, and euro as funding currencies in the months ahead.
The gains are broad. G10 carry trades have returned around 8% so far in 2026, outperforming global bonds, gold, and Bitcoin, though equity markets have delivered stronger returns. The hedge fund industry as a whole is up about 8% for the year despite a midsummer technology-stock unwind that trimmed gains at firms such as Coatue, which fell 8.3% in July amid the AI-stock rout.
The Mechanism: Low Volatility Is the Oxygen, Not the Story
The surface explanation for the carry trade's success is the interest-rate gap. The deeper explanation is the volatility regime. A carry trade is, at its core, a short-volatility position dressed up as an income strategy. Every day that currencies do not move, the trader collects yield. Every day they do, the position's currency leg moves against the yield pickup — and because these trades are typically leveraged, even a modest adverse currency move can erase months of carry in a single session.
This is why the current backdrop is so potent — and so fragile. The combination of persistent yield dispersion and reduced expectations for significant central-bank policy shifts has suppressed exchange-rate volatility, improving the risk-reward profile for the strategy, Goldman Sachs said. When traders believe the Fed, the ECB, and the Bank of Japan will all stay roughly where they are, currency ranges tighten, and the carry trade prints money. The moment one of those central banks surprises, the range breaks, and the trade reverses in the opposite direction with leverage applied.
There is a second-order channel here that most commentary skips. The carry trade is not just a currency-market phenomenon — it is a cross-asset funding machine. When volatility is low and the carry trade works, leveraged investors use currency funding to buy risk assets: emerging-market bonds, high-yield credit, dividend stocks, even commodities. That is why a currency carry unwind can show up as a stock-market selloff. In late July and early August 2024, a Bank of Japan rate hike — from around zero to 0.25% — sent the yen up nearly 10% against the dollar and, between July 31 and August 5, left Japan's Nikkei 225 down about 20%, its worst stretch since 1987. The trigger was a Japanese rate decision. The damage spread through global equities because the carry trade was the funding leg beneath both.
That transmission channel is active today. With the yen near its weakest level in four decades and hedge funds positioned more bearishly than at any point since 2007, the market has effectively underwritten a world in which the Bank of Japan does nothing surprising. That is a bet with an asymmetric payoff: steady gains if the BOJ stays put, violent losses if it does not. The same logic applies to the Fed. If U.S. rates move in a direction that narrows the roughly 260-basis-point yield gap between Washington and Tokyo — or if the dollar strengthens sharply — the incentive to borrow in dollars and invest abroad shrinks quickly, and the unwind can be disorderly because everyone is crowded on the same side of the trade.
The Cyclical Call: This Is a Regime, Not a Trend — and Regimes End
The critical question for investors is whether the current carry-friendly environment is cyclical — a temporary window that will close — or structural — a new regime that will persist. The evidence points clearly to cyclical.
A structural shift would require a permanent change in the rules of the game: a lasting reordering of global capital flows, a durable change in central-bank behavior, or a fundamental rewiring of how currency risk is priced. None of those is present. What is present is a specific, temporary confluence: the Fed holding at 3.50%-3.75% while other central banks are at different points in their cycles, a dollar whose volatility has compressed, and a geopolitical backdrop that markets have so far shrugged off. Each of these is mean-reverting by nature. Central banks do not hold still forever. Volatility clusters and then spikes. Currency trends that last four years — the yen's decline — eventually attract intervention, as Japan's roughly $74 billion of spring 2026 spending demonstrated.
The historical record is unforgiving on this point. Carry trades do not fade; they break. The 2008 financial crisis, the 2013 taper tantrum, and the August 2024 yen unwind all followed the same pattern: long periods of steady gains punctuated by sudden, sharp reversals. The common denominator was not a change in fundamentals but a change in volatility. Once the volatility regime shifts, the yield gap no longer compensates for the currency risk, and the trade unwinds in a rush as leveraged positions are liquidated simultaneously.
Analysts at Morgan Stanley and Bank of America have expressed confidence that, absent unforeseen macroeconomic shifts, current trends should persist through 2026. That framing is itself the tell: the strategy's continuation is conditional on nothing surprising happening. A trade that works only if the world behaves is a trade that fails when it does not.
The Counter-Thesis: Why This Time Could Be Different
The strongest argument against the cyclical call is that the market has learned from 2024. Carry-trade positioning is better hedged now than it was two years ago, the argument runs. The Bank of Japan's communication is clearer, so a rate move is less likely to surprise. And the yield gaps are wide enough — roughly 260 basis points between the Fed and the BOJ — that the trade can absorb more currency movement before it turns unprofitable. Even a leveraged carry position remains profitable through a 250-basis-point differential, the logic goes, so the trade does not unwind because rates converge gradually.
There is truth in this. Hedging has improved, and the BOJ has been more transparent about its policy path. Goldman Sachs, among others, argues that BOJ policy expectations are better priced in than a couple of years ago. If the unwind risk is genuinely lower, then the current carry premium is compensation for a smaller risk than the market historically demanded — and the trade deserves to work for longer.
But this argument confuses better hedging with lower systemic risk. Hedging transfers risk; it does not eliminate it. When volatility spikes, hedges that worked in calm markets often fail precisely because everyone is trying to buy protection at once — the cost of hedging rises, and the protection becomes less effective just when it is needed most. Moreover, the improved-payout argument cuts both ways: if the yield gap is wide enough to make the trade profitable through a 250-basis-point move, it is also wide enough to attract more capital, which means more crowding, which means a faster unwind when the exit door narrows.
The falsifying signal for the cyclical view is specific: if emerging-market currency volatility remains below G7 volatility for another 12 months — extending the streak well past the 208-day record threshold — while the Fed holds rates steady and the yen stays above 155 per dollar, then the low-volatility regime is more durable than a temporary window, and the structural argument gains force. Conversely, if the JPMorgan gauge of six-month emerging-market currency volatility rises back above its five-year average, or if the yen strengthens more than 5% against the dollar in a month, the cyclical unwind thesis is confirmed.
What's Next: The Signals That Matter
The carry trade's fate now rests on three watchpoints. First, the Federal Reserve: with three FOMC members already dissenting for a hike, any move toward tightening would strengthen the dollar and compress the yield gaps that fund the trade. A hawkish pivot would be the fastest route to a reversal. Second, the Bank of Japan: another rate hike, or even credible signaling of one, would lift the yen and force the most crowded short position in the market to cover. Third, volatility itself: the one-month implied volatility on the Bloomberg Dollar Spot Index and JPMorgan's six-month emerging-market currency volatility gauge are the canaries. When they turn up, the carry trade's oxygen is being removed.
By time horizon, the picture splits. In the short term — the next quarter — the setup remains favorable. Yield gaps are wide, volatility is low, and positioning, while crowded, has room to run if central banks stay put. In the medium term — six to twelve months — the risk rises as the Fed's next move becomes clearer and as the yen's four-year decline invites more aggressive intervention from Tokyo. In the long term, the structural forces are neutral to negative for the trade: global rate differentials tend to compress over time, and a decade of low volatility is statistically more likely to be followed by a regime of higher volatility than by a continuation of calm.
The base case is that the carry trade grinds higher through the rest of 2026, with G10 strategies adding to their 8% year-to-date gain, before a volatility event — most likely a central-bank surprise or a geopolitical shock that markets stop absorbing — triggers a sharp but contained unwind. The upside case is that the low-volatility regime persists into 2027, central banks remain on their current paths, and the carry trade delivers another strong year, with the yen continuing to weaken toward Goldman Sachs' 12-month forecast of 165 per dollar. The downside case is a repeat of August 2024: a policy surprise lifts the yen or strengthens the dollar, volatility spikes, and the unwind spreads from currencies into equities and credit as leveraged positions are liquidated in unison.
For investors, the implication is asymmetry, not abstention. The carry trade pays steadily in calm markets and punishes severely in volatile ones. Those already in the trade should treat rising volatility gauges as an exit signal, not a buying opportunity. Those considering entry should understand that they are not collecting yield — they are selling insurance against a volatility spike, and the premium looks generous only because the last claim was filed two years ago.
The carry trade is not riding high because investors have discovered a new source of return. It is riding high because the price of risk has been temporarily suppressed — and markets that suppress the price of risk for long enough always, eventually, collect the bill.
