Foreign governments cut U.S. Treasuries in March as the Middle East war forced central banks to liquidate dollar reserves, defending local currencies against an energy shock that sent exchange rates tumbling.
China reduced its holdings to $652.3 billion, down roughly 6% from February to the lowest level since September 2008, according to U.S. Treasury data released late Monday stateside.
Japan, the single largest foreign holder of U.S. government debt, shed approximately $47 billion to $1.191 trillion. Overall foreign holdings fell to $9.25 trillion in March from $9.49 trillion in February.
The selloff came as the outbreak of the U.S.-Iran conflict and a subsequent surge in crude oil prices sent the Japanese yen and other Asian currencies tumbling. Regional economies reliant on Gulf oil imports, including Japan, faced the largest energy shock in decades, prompting policymakers to sell part of their dollar-denominated assets to fund currency intervention.
"Given increased financial volatility since the start of the war in the Gulf, and resultant pressure on exchange rates, especially in Asia, it is not a surprise that U.S. Treasury holdings by central banks have fallen," said Frederic Neumann, chief Asia economist at HSBC.
"Exchange market intervention to support local currencies will have led some central banks to sell a share of their U.S. Treasury holdings."
The data for April, due next month, may show just how far central banks are willing to go to stabilize their currencies.
Policy makers also tend to recalibrate portfolios during bouts of market stress, with some selling reflecting tactical concerns about rising inflation and falling bond values — a move into cash-like assets to ensure liquidity should intervention needs escalate, Neumann said.
Treasuries have come under significant pressure with yields surging as the Middle East conflict stoked inflation fears and prompted investors to demand higher compensation for holding U.S. debt.
The selloff in foreign holdings also reflected falling bond prices, as foreign investors logged a $142.1 billion valuation loss on long-term Treasury holdings in March alone.
Bucking the trend, the U.K. added roughly $29.6 billion to its holdings to $926.9 billion in March, as several smaller holders pulled back.
## 'Shadow holdings'
China has been gradually reducing its direct Treasury exposure since peak holdings of around $1.3 trillion in 2013, but analysts have long argued official figures undercount its true footprint in U.S. debt markets. Custodial centers like Belgium and Luxembourg are widely seen as conduits for Chinese sovereign wealth and state-linked investment.
If such "shadow holdings" are included, their aggregate figure appeared relatively steady, said Tianchen Xu, senior economist at the Economist Intelligence Unit. Belgium held $454.0 billion of U.S. government debt in March, roughly flat from the February level, while Luxembourg's holding levels have been stable over the past year, around $439.4 billion.
"China's overall holding of USTs [is] staying largely stable for the time being, with short-term market volatility being the key factor driving a decline in near-term holding," said Becky Liu, Managing Director of Global Research and Fidelity International.
For Japan, the question of whether Tokyo *w*ill resort to sustained Treasury liquidation to fund yen intervention has also drawn attention in Washington in recent weeks.
The Bank of Japan was reported to have intervened in currency markets in late March and early April after the yen weakened past the politically sensitive 160 level, as surging oil import costs widened Japan's current account deficit and stoked fears of a depreciation spiral.
Vikas Pershad, portfolio manager at M&G Investments, told CNBC earlier this month that the signal from U.S. policymakers was clear that they hoped "the preferred policy option [for Japan] is not selling Treasuries. He pointed to trade deals in critical minerals, advanced technology, and defense as alternative opportunities that could help reduce pressure on Japan's foreign exchange reserves.
Four leading AI models discuss this article
"Central bank sales to fund currency defense risk extending the Treasury yield spike beyond what domestic inflation fears alone would produce."
Foreign central banks selling U.S. Treasuries to defend currencies against oil-driven shocks from the U.S.-Iran conflict adds near-term pressure on already surging yields. Japan cut $47 billion and China hit its lowest holdings since 2008, with total foreign ownership dropping $240 billion in March. Valuation losses of $142 billion from falling bond prices compound the effect. While shadow holdings through Belgium and Luxembourg look stable, sustained intervention could force more liquidations if the yen stays weak past 160. April data will clarify whether this is tactical or a structural shift away from dollar assets.
The reported declines largely reflect mark-to-market losses and short-term intervention needs rather than outright dumping; once currencies stabilize, central banks may rebuild positions quickly, limiting any lasting impact on yields or the dollar.
"Foreign Treasury selling in March was driven by currency defense mechanics, not conviction to exit dollar assets—the real test is whether April shows sustained liquidation or a rebound as oil volatility subsides."
The headline screams 'foreign governments fleeing Treasurys,' but the math tells a different story. Yes, China hit a 15-year low at $652.3B and Japan shed $47B, but total foreign holdings fell only $240B (2.5%) month-over-month—modest for a geopolitical shock. The article itself admits China's 'shadow holdings' through Belgium ($454B) and Luxembourg ($439B) remained flat, suggesting Beijing is rotating, not retreating. Japan's $47B sale is real, but represents 3.9% of their $1.191T position—tactical currency defense, not a structural pivot away from USTs. The UK actually added $29.6B. The real risk isn't a Treasury exodus; it's whether sustained oil shocks force Japan into *repeated* liquidations, which could create a feedback loop.
If April data shows Japan and China continuing to sell at March's pace, we'd have evidence of a structural shift rather than one-month noise—and the article explicitly flags that April data will be the tell. Additionally, the article may understate how much custodial holdings obscure true Chinese exposure, meaning the 'shadow holdings' thesis could itself be incomplete.
"The liquidation of Treasuries is a tactical necessity to fund currency defense, which creates an artificial upward pressure on long-term yields that will eventually compress equity multiples."
The headline-grabbing liquidation of Treasuries by Japan and China is less a structural abandonment of the dollar and more a tactical necessity of energy-importing nations facing a supply-side shock. While the $240 billion drop in foreign holdings is notable, it is largely a liquidity play to defend currencies against the oil-fueled inflation surge. The real risk isn't a 'run' on U.S. debt, but the impact of sustained intervention on the Term Premium—the extra yield investors demand for holding long-term bonds. If the Bank of Japan continues to sell at this velocity, we could see a disorderly spike in the 10-year Treasury yield, pressuring equity valuations across the S&P 500.
The bearish case ignores that this is a zero-sum game; if central banks sell Treasuries to buy yen, that liquidity eventually flows back into the U.S. financial system, potentially cushioning the blow to bond prices.
"Official selling in March is unlikely to herald a durable re-pricing of U.S. Treasuries; reserve status and private demand provide a stabilizing backstop."
March data show foreign central banks trimmed US Treasuries as they defend currencies amid Gulf oil shocks and yen depreciation. The obvious read is a bearish tilt for Treasuries and a dollar bid, but there are caveats. The article underplays that much of the decline could be tactical liquidity moves rather than a durable shift in reserve holdings; ‘shadow holdings’ via custodians may keep net exposure steadier than it appears. The U.S. remains the world’s deepest, most liquid debt market with ongoing private demand, which can absorb official selling. April data will matter for persistence; near-term moves may be volatility-driven rather than structural.
The halt in the decline could be temporary, and if custodial estimates inflight, the actual official selling may be far less dramatic than headlines imply; hence, the risk of a sustained Treasury bear move is overstated.
"Sustained sales could widen term premium quicker than recycling cushions, accelerating yield pressure beyond April data signals."
Gemini's zero-sum recycling argument understates how sustained BoJ liquidations at March's pace could lift term premium faster than private inflows offset. With oil shocks ongoing, repeated yen defense sales risk pushing 10-year yields toward 4.6% by summer even if custodians mask some Chinese exposure. That tightens financial conditions before any liquidity loops back, pressuring housing and capex more than equity valuations alone suggest.
"Currency defense selling is event-driven, not structural; the real risk is a *concurrent* shock forcing multiple central banks to liquidate simultaneously, not March's pace repeating."
Grok's 4.6% yield call by summer assumes BoJ sells at March's $47B pace continuously—but that's not how currency defense works. Once yen stabilizes above 155, selling pressure eases sharply. The real tail risk isn't sustained liquidation; it's a *shock* event—say, a 200bp oil spike—forcing simultaneous intervention by Japan, Korea, and India. That's when term premium spikes. March alone doesn't prove the velocity persists.
"The structural issue is not foreign selling velocity, but the Treasury's massive supply requirement meeting a price-sensitive private buyer base during QT."
Claude and Grok are fixating on the BoJ, but you're all ignoring the fiscal side: the Treasury's issuance schedule. Even if foreign selling is tactical, the U.S. is running a $1.5T+ deficit. Private demand is price-sensitive, not price-insensitive like central banks. If foreign official buyers step back, the 'term premium' doesn't just spike from intervention—it resets higher because the market must absorb record supply at a time when the Fed is still doing QT.
"The real test is regime-switch risk from oil shocks and multi-actor interventions, not a linear move to 4.6% in yields."
Grok, your 4.6% scenario rests on perpetual BoJ yen-defense selling; in practice, policy moves are non-linear and can reverse quickly. The bigger risk isn’t a straight line higher in yields, but a regime switch triggered by a sharp oil shock that prompts synchronized interventions. That could spike term premia briefly, then unwind—creating volatility and financial-stress pockets, not a straightforward bear-case for Treasuries.
The panel agrees that foreign central banks' selling of U.S. Treasuries is largely tactical, driven by currency defense against oil-driven shocks, rather than a structural shift away from dollar assets. However, they caution that sustained intervention could lead to disorderly spikes in yields, pressuring equity valuations and tightening financial conditions.
