Short the Measuring Stick: Debasement as the Macro Meta-Trade

Dollar dominance was - and still is - embedded across every layer of the financial system, from equity benchmarks and bond markets to commodities pricing and global funding chains. That old framework is broadly breaking.

The debasement trade is now taking hold, marked by a gradual flight from fiat-denominated assets toward safe havens and hard assets, as confidence in the long-term stability of the financial system’s measuring stick - the US dollar - continues to erode. 

The sharp moves in USD/JPY observed since 23 Jan should not be interpreted as a standalone FX event, but as a confirmation of broader US dollar weakness already underway. It simply became the most visible pressure point. 

The pair experienced its largest one-day decline since August 2025, with losses extending into the beginning of the week, bringing the total move to roughly -4.5% from Friday’s highs. 

On 23 Jan, the New York Fed conducted a rate check - inquiring about USD/JPY exchange costs - at the request of Japan’s Ministry of Finance (MOF). No intervention was formally announced, but that was beside the point. A rate check is a pre-intervention signal that communicates a clear tolerance for further dollar weakening, with authorities prepared to act if conditions worsen.  

Markets reacted immediately, as participants began to price in the possibility of coordinated US–Japan action in the currency, a channel that has not been activated since the G7 intervention following Japan’s 2011 earthquake. 

However, the subsequent amplitude of the move suggests that signaling alone may not fully account for the price action. The magnitude of the decline was larger than would typically be expected with verbal guidance. 

On 25 Jan, Prime Minister Sanae Takaichi warned of "necessary measures" against "speculative and highly abnormal" market moves, suggesting that Japanese authorities may have already intervened directly in the market over the past few days. 

The Japan-US financial nexus

In earlier intervention attempts, gains achieved through unilateral Japanese intervention have proven difficult to sustain over time. In 2024, Japanese authorities directly intervened in foreign exchange markets on four occasions, buying roughly ¥17.3tn ($98bn) to support the yen against the dollar, according to the MOF. 

While these operations generated sharp short-term reversals, the effects faded as underlying pressures reasserted themselves. 

This time, however, the dynamic may be different. US authorities historically step in when the FX situation looks out of control, posing broader financial stability risks. To contain broader financial contagion, policymakers usually move to stabilize USD/JPY by selling dollars and buying yen, capping disorderly moves between both currencies.  

To put the current dynamics into perspective, let’s look back to the dawn of the 2000s – especially the Asian Financial Crisis. At that time, the US participated in a rare and direct foreign-exchange intervention, joining the Bank of Japan’s efforts to support the yen against the dollar. 

The initial inflection in the currency pair came from US officials considering a trip to Tokyo, which was enough to reverse momentum and push USD/JPY decisively away from stress levels amid continued yen weakness. 

The following day, official US intervention – roughly $1bn in participation - extended the move, reinforcing the yen’s appreciation and stabilizing the pair for a while.  

But there is a valid and key question: why would the US step in at all?

The answer has little to do with supporting Japan for its own sake. It has everything to do with protecting the core of the US financial system. 

The yen is being selectively bailed out to prevent Japanese institutions from being forced to sell US assets. 

When USD/JPY moves too far, too fast, it raises the probability of forced liquidation of US assets by Japanese institutions, among the largest foreign holders of US Treasuries, as it mechanically turns into balance-sheet stress.

Japan is a massive global creditor, particularly vis-à-vis the US. By the end of 2024, more than half of Japan’s public-sector foreign assets were invested in US markets (including bonds and stocks), according to Bloomberg. 

This basically implies that the bulk of more than $2.5tn sits in dollar-denominated assets, likely unhedged, and carrying substantial mark-to-market gains that the public authorities could realize to alleviate Japan's debt burden.  

The risk is being amplified by developments in Japan’s domestic bond market. Japanese government bond yields have continued to push to extreme levels, with volatility along the long end of the curve reaching heights not seen in decades. Rising fiscal risk premia, combined with political uncertainty ahead of the February snap election - framed by Prime Minister Sanae Takaichi as a "mandate-seeking exercise for expanded spending" - have pushed yields higher while simultaneously widening FX risk premia. 

This configuration breaks the traditional relationship whereby higher yields support the currency. Rather than signaling strength, the inversion reflects rising stress. If left unchecked, it risks propagating beyond FX into global funding markets and, eventually, the US Treasury market. 

The yen as a global risk barometer

Over the past two years, episodes of sharp yen appreciation against the dollar have consistently coincided with broader risk-off market responses across risk assets. 

The first occurred around July–August 2024, when Japan’s Ministry of Finance intervened to market support yen, followed shortly by a policy rate hike after years of ultra-loose regime. Risk assets sold off sharply: the S&P 500 declined by roughly 7.1%, Bitcoin fell by 5.9%, and gold was broadly flat. 

The second episode began early January 2025, amid escalating tariff rhetoric from the US president. As USD/JPY moved lower, the S&P 500 dropped by 11.5% and Bitcoin by 7.6%, while gold surged more than 27%, decisively outperforming as the globally accepted store of value.

Still, this does not contradict the broader relationship between dollar weakness and risk assets. Outside of Japan-specific shocks, periods of generalized weakness in the Dollar Index (DXY) have historically been supportive of long-tail risk assets, including Bitcoin. 

Yen-driven FX moves tend to be associated with funding stress, carry trade unwinds, and balance-sheet deleveraging - dynamics that overwhelm the usual "weak dollar equals risk-on" relationship. 

But so far, Bitcoin has failed to capture the debasement trade. Bitcoin closed the past year in negative territory after giving back yearly gains in late-Q4, contrasting sharply with gold and silver, which delivered their strongest annual performance in decades.   

In the current cycle, leadership within the debasement trade has clearly favored traditional hard assets. 

Part of the explanation lies in Bitcoin’s behavior during stress. BTC continues to be reduced aggressively in risk-off environments and remains highly correlated with equity sell-offs when liquidity tightens. In moments of broad de-risking, Bitcoin still trades less like a monetary hedge and more like a high-beta risk asset.  

That said, Bitcoin’s role should not be dismissed outright. It has demonstrated hedging properties during episodes of economic and institutional regime stress - notably outperforming during the Silicon Valley Bank (SVB) collapse and the subsequent regional US banking crisis in 2023. 

For now, gold has taken center stage as the preferred monetary hedge, while Bitcoin remains in the waiting room, largely overshadowed by its tangible counterpart.

"The dollar is doing great”

These are US President Donald Trump’s own words; meanwhile, DXY printed a multi-year low, breaking below the 96 lower bound that held throughout the past year. This reflects the broader softening in the dollar across major crosses, and the US's willingness to deal with a weaker USD. 

Currency volatility becomes the primary macro transmission mechanism rather than a secondary effect - showcasing what “short the measuring stick” looks like in practice. 

Central banks now hold more gold by value than US Treasuries, a shift reinforced by the underlying continued rally. That development quietly flips the reserve hierarchy of the global system, where Treasuries are no longer viewed as the unquestioned safest store of value. Reserves are rotating away from politically tied, defaultable assets toward neutral, non-defaultable settlement instruments. 

Gold and Silver have entered price-discovery territory, pushing through key psychological price levels at $5,000 and $100, respectively. Turnover of the latter is now running at more than fifteen times its historical average, exceeding $30bn per day - more than any other security, including the S&P 500, the Nasdaq, and even gold itself – extreme moves reflecting broader repricing of monetary credibility.  

But from a balance-sheet perspective, a dollar weakness policy can be advantageous for the US. For a heavily indebted sovereign, currency depreciation functions as an adjustment mechanism: liabilities remain fixed in nominal terms while their real economic weight diminishes over time.

 At the same time, a lower exchange rate improves the pricing of domestic production abroad, easing external imbalances. 

But this is only one side of the coin. 

Dollar-denominated assets’ performance mirage

When the reserve currency is being devalued, USD-priced assets can rise mechanically in nominal terms. That can lure USD-based investors into thinking they generated "alpha," when part of the performance is simply the global measuring stick shrinking. 

Once the same position is translated back into a non-USD base currency, the latter variation (FX) shows up directly in realized returns - highlighting that performance is far from even for global investors on either side of the Atlantic and the Pacific. 

What appears as solid performance in USD terms looks materially weaker - and in some cases vanishes entirely - for non-USD investors:

• Take Bitcoin as an example first. While BTC is up 33.5% in USD, returns fall to 17.9% for euro-based investors and 17.2% for Swiss franc investors - roughly half the USD performance. 

• The same effect is visible in the other asset classes. Gold’s +93% USD return over the period erases close to one-third of the performance once FX is accounted for - a meaningful discount relative to the headline USD gain.

• US equities make the point even more stark. The S&P 500’s +18.7% USD return turns roughly flat for European investors. Meanwhile, for say, Swiss investors, the past performance even turned negative, despite what appears to be a respectable double-digit gain in USD nominal terms.  

That’s the "inflated returns" trap. In simpler terms, if an S&P 500 position rises 20% in USD over the year but the investor’s home currency appreciates 20% against the dollar over the same period, the effective return is close to zero.

Sophisticated investors can mitigate this effect by hedging currency exposure through forwards or futures, locking in FX rates between counterparties. For most traditional investors, however, such hedging is either impractical, costly, or simply not implemented – FX changes quietly dominate real realized returns relative to the expected USD headline. 

For the latter, the simplest alternative is to remain invested in assets denominated in one’s base currency, or to use instruments with embedded FX hedges - typically at the cost of higher fees. 

In crypto, however, this approach quickly becomes complex.

Stablecoins do not hedge currency debasement 

One aspect of the debasement trade remains largely overlooked in crypto markets: stablecoins do not protect investors from underlying currency volatility. In practice, they can even amplify it. 

Despite its promise of financial disintermediation, the crypto industry has largely replicated the currency structure of the traditional financial system. Just as commodities are priced and traded in dollars, most crypto assets are accessed, traded, and collateralized through dollar-denominated pairs. 

Buying Bitcoin still overwhelmingly means trading against USDT or USDC - the most liquid and dominant markets in the ecosystem. DeFi, in that sense, remains deeply dollar-centric as well. 

But the geographic distribution of stablecoin usage highlights a striking disconnect. Europe and the US each account for roughly 35% of stablecoin usage, with Asia close behind at around 20%. Yet despite this global footprint, the stablecoin supply itself is almost entirely dollar-based.

Out of roughly $306bn in circulating stablecoins, more than 99.8% are USD-denominated. Euro-denominated stablecoins barely exceed $600mn in total supply, with Circle’s EURC accounting for roughly $400mn. Outside of that, viable alternatives in other currencies are either negligible or effectively non-existent. 

This has concrete consequences. Almost all DeFi opportunities remain trapped in a dollar-dominated equilibrium. Yield, lending, liquidity, and composability overwhelmingly sit in USD terms, shaping investor behavior around nominal returns rather than real outcomes.

Over the past six months, USDC nominal yields consistently hovered between 4% and 5.5%. But according to Sandmark analysis, when translated into euro terms, real USDC yields steadily compressed, falling toward the 1–2% range by early 2026 as EUR/USD moved against dollar holders. 

By contrast, EURC yields - while lower in nominal terms, averaging around 3–4% - delivered superior outcomes for euro-based investors once currency effects were taken into account. At several points, a 3–3.5% yield on EURC materially outperformed a 5%+ yield on USDC on a currency-adjusted basis. 

That leaves non-US investors structurally exposed to dollar risk, even when they believe they have “de-risked” by moving into stables. In real terms, stablecoins inherit the debasement of their underlying currency, and what appears attractive in nominal USD terms can be quietly destructive in real purchasing-power terms as the dollar weakens. 

For European investors, holding USD stablecoins over recent weeks has resulted in losses approaching 5% solely due to FX moves. Even without taking market risk, capital has been eroded.  

The irony is that this happens precisely when investors seek safety. Crypto participants often rotate from volatile assets into stablecoins to reduce risk or take profits, only to find that their portfolios continue to bleed against their home currency. 

Trading out of USD exposure is not a practical solution either. Onchain swaps into EUR-denominated stablecoins or assets suffer from thin liquidity, wide spreads, and high slippage - a structural brake that tokenized assets experience as well. Small markets mean shallow order books, which makes FX diversification costly and inefficient. 

What's next?

As the debasement trade accelerates, crypto’s dollar dependence becomes a vulnerability rather than a strength. Without deeper liquidity, better integration, and credible yield opportunities in non-USD currencies, global crypto investors are left with a false choice between volatility and silent erosion. 

Until DeFi evolves beyond its dollar monoculture, "stable" will remain a misleading label, and the debasement trade will continue to play out in crypto in ways most participants are not yet pricing in.
