Post Xi Visit: A Summit Overview Part II.
If China is indeed mobilizing for a “return of funds” from tax havens then where would the fingerprints show up?
Would they be hidden?
That’s the central question we try to explore here.
The Ghost in the Plumbing — Sovereign Squeezes and the Offshore Liquidity Mirage
In the weeks surrounding the bilateral summit, global FX desks have had a perfectly conventional explanation for the aggressive rise in USD/CHF: the Swiss franc has become an attractive funding currency as the Swiss National Bank holds its policy rate at zero while interest rates and Treasury yields elsewhere remain substantially higher.
That explanation has real evidence behind it.
But it may not explain everything.
The more interesting question is whether the visible currency trade is merely the surface layer of a much larger movement of capital underneath it.
This is the central proposition of Part II of our post-summit investigation: what if the plumbing matters as much as the price?
The Currency Mirage: Why the Markets May Be Looking at the Wrong Chart
USD/CHF reached approximately 0.8311 on September 28, 2026. The move is striking when viewed against the franc's position earlier in the year: USD/CHF traded around 0.76 at its 2026 low before reversing substantially.
The conventional interpretation is straightforward. The SNB's policy rate is currently 0%, while the Federal Reserve and other major central banks offer considerably higher returns on short-term dollar assets. The franc therefore possesses one of the defining characteristics of a funding currency.
The SNB itself has previously documented the relationship between carry-trade positioning and USD/CHF. Its research found that carry-trade activity can influence exchange-rate dynamics and that sudden unwinding can produce significant franc appreciation.
The latest SNB research adds another layer. Its 2026 work on the USD/CHF cross-currency basis finds that dollar demand, intermediary-dealer balance-sheet constraints, monetary-policy announcements and funding stress can all alter the price of dollar funding.
In other words, the plumbing really does move the price.
There is also direct evidence of speculative positioning. CFTC futures data show non-commercial traders holding a net short Swiss-franc futures position of roughly CHF 3.62 billion notional on September 15 and CHF 3.34 billion on September 22, using the standard CHF 125,000 futures contract size.
That is not proof of a particular strategy. "Non-commercial" is a regulatory classification, not a declaration that every short position represents a carry trade. But the positioning is certainly compatible with a market in which investors are selling the low-yielding franc and acquiring higher-yielding assets elsewhere.
The Switzerland-to-Beijing Pipeline
Now comes the more speculative proposition.
Beijing has intensified scrutiny of offshore wealth. Recent reporting describes a more aggressive enforcement environment surrounding overseas assets, trusts and offshore income. That makes the question of capital repatriation legitimate.
But there is a crucial distinction between saying that China is attempting to increase control over offshore wealth and saying that a particular USD/CHF move is the visible exhaust of a centrally coordinated repatriation operation.
The first proposition is documented.
The second remains a hypothesis.
Suppose, however, that the hypothesis is correct.
The architecture becomes fascinating.
Step 1: The CHF Vacuum
An ultra-wealthy client with liquid Swiss-franc assets could theoretically sell CHF and move into dollars. If enough similarly positioned investors acted at once, the aggregate flow would reinforce the existing macro pressure on the franc.
This would be almost indistinguishable on an FX chart from an ordinary funding trade. That is precisely what makes the hypothesis interesting.
Step 2: The Dollar Clearing Parking Spot
The dollar offers an enormous intermediate pool of liquidity. A dollar position can be held in bank deposits, money-market instruments, Treasury bills, repos, custody accounts or other highly liquid assets.
A dollar balance therefore provides something that a direct CHF-to-CNY conversion does not: an intermediate asset whose global liquidity is so deep that the transaction becomes harder to interpret from the originating currency pair alone.
This is where the title's "liquidity mirage" becomes useful. The chart tells us that someone wants dollars against francs. It does not tell us why.
Step 3: The Short-Term Yield Mirage
If dollars were temporarily being accumulated while legal, tax or regulatory processes were being completed, short-duration U.S. government securities would be a natural place for a risk-conscious investor to park liquidity.
But again, this is a mechanism that could exist. It is not evidence that the mechanism is currently being used by Chinese billionaires on a coordinated basis.
The Swiss Banking Counter-Evidence
If the alternative explanation is simply a giant CHF-funded carry trade, the Swiss banking system provides plenty of infrastructure capable of supporting it.
UBS remains the dominant Swiss wealth-management institution. Julius Baer, Pictet, Lombard Odier and Union Bancaire Privée also operate substantial private banking and portfolio-financing businesses.
The scale is considerable. Swiss Banking's 2026 Banking Barometer reports total Swiss wealth under management of approximately CHF 9.73 trillion and cross-border private-client assets of approximately CHF 2.95 trillion.
Julius Baer alone reported CHF 36.2 billion in Lombard loans at June 30, 2026. That figure demonstrates the scale of collateralized private-banking financing available through a major Swiss institution.
None of those numbers should be described as "carry-trade exposure." Lombard loans are loans secured against portfolios. A bank's assets under management are not the same thing as FX positions. And a bank facilitating an FX transaction does not necessarily retain the corresponding currency exposure on its own balance sheet.
At present, public disclosures do not provide a defensible bank-by-bank estimate of the amount of CHF funding specifically being used for USD/CHF carry trades. Any precise number would therefore be speculation.
What the Public Data Actually Tell Us
Documented
- The SNB policy rate is 0%.
- USD/CHF has risen substantially during 2026.
- Speculative futures positioning shows a sizeable net short CHF position.
- The Swiss franc has a documented history as a funding currency.
- Dollar funding conditions and cross-currency basis materially affect USD/CHF.
- Swiss private banking operates at multi-trillion-franc scale.
- China has intensified scrutiny of offshore wealth and cross-border financial activity.
Possible but unproven
- Chinese private wealth could be liquidating dormant CHF balances.
- Dollar assets could be functioning as an intermediate parking place.
- Some offshore wealth could eventually be repatriated into China.
- Alternative settlement networks could eventually reduce the visibility of bilateral FX flows.
Not demonstrated by the available public evidence
- A centrally coordinated Beijing operation targeting the CHF specifically.
- A measurable Switzerland → USD → CNY repatriation pipeline.
- A specific dollar amount of Chinese billionaire capital currently sitting in U.S. Treasury bills for this purpose.
- A bank-specific estimate of CHF carry positions attributable to Chinese clients.
- Use of mBridge as a current covert conduit for this wealth.
Erasing the Fingerprints: Alternative Shadow Conduits
1. The Middle Eastern Sovereign-Wealth Interface
The deepening financial relationship between China and Gulf economies creates another theoretical layer of intermediation.
Joint ventures, infrastructure investment, industrial partnerships and sovereign investment vehicles can create legitimate cross-border capital movements that are difficult to interpret solely from an FX chart.
But legitimate Gulf-China investment should not automatically be treated as a cover for Chinese capital repatriation. The distinction matters.
2. Trade and Commodity Valuation
Trade misinvoicing is a long-established mechanism for transferring value across borders. Commodities such as copper, gold, lithium and agricultural products can provide enormous transaction values relative to physical shipment volumes.
That makes commodity trade an interesting area for investigators to monitor. It does not, however, mean that unusual commodity flows are automatically evidence of Chinese offshore wealth being repatriated.
3. Alternative Clearing and Digital Settlement
This is perhaps the most strategically important part of the thesis.
Project mBridge demonstrated that multiple central banks could experiment with shared digital settlement infrastructure. Its participants included the People's Bank of China, Hong Kong Monetary Authority, Bank of Thailand, Central Bank of the UAE and Saudi Central Bank.
But the chronology matters: BIS now describes mBridge as a concluded project that reached minimum viable product stage in 2024.
Therefore the interesting question is not whether mBridge is secretly processing today's billionaire flows. There is no public evidence establishing that.
The more durable question is what happens when countries possess settlement infrastructure capable of reducing the number of times a transaction must pass through Western correspondent-bank architecture.
The Sovereign Conclusion
The mistake in conventional analysis may not be that it believes in carry trades. The mistake may be assuming that the existence of a carry trade exhausts the explanation.
The public evidence currently gives us a very plausible conventional story: zero Swiss rates, substantial interest-rate differentials, dollar demand, cross-currency funding effects and sizeable speculative short-franc positioning.
But that story does not tell us where every dollar ultimately goes.
Nor does a currency chart identify the beneficial owner behind every transaction.
That is the opening for the shadow hypothesis.
The visible trade says "carry."
The invisible-flow hypothesis asks whether carry is merely the surface expression of a deeper redistribution of offshore liquidity.
If Beijing really is attempting to pull portions of China's offshore private wealth back inside sovereign financial boundaries, the most interesting evidence may not appear first in Chinese FX statistics.
It may appear indirectly—in Swiss franc positioning, dollar funding markets, short-duration Treasury demand, private-bank balance sheets, commodity trade settlement, Gulf investment structures and the gradual migration of payment infrastructure away from traditional correspondent-bank channels.
That is the ghost in the plumbing.
We should not claim to have caught it.
But we can watch the pipes.
Evidence Ledger: What Would Confirm the Hypothesis?
If this theory is correct, several independent data points should eventually move together.
- A sustained increase in Chinese offshore-asset repatriation or tax enforcement.
- Unusually large reductions in CHF-denominated offshore wealth among relevant client populations.
- Persistent short-CHF positioning beyond what interest-rate differentials alone would explain.
- Unusual increases in short-duration dollar assets associated with identifiable offshore wealth channels.
- Changes in Swiss-bank cross-border claims or custody composition inconsistent with ordinary portfolio rebalancing.
- Increasing China/Gulf settlement activity that cannot be explained solely by trade and direct investment.
- Evidence that final CNY conversion is occurring through state-linked or otherwise controlled financial channels.
Until several of these signals appear simultaneously, the prudent interpretation is that the Beijing liquidity-repatriation thesis remains an investigative hypothesis, not a demonstrated explanation for USD/CHF.
And that distinction is precisely what makes the investigation worth continuing.
