Exclusive-Chinese banks purchasing Treasuries after wooing dollar deposits, sources say

Chinese banks have reportedly increased purchases of U.S. Treasuries over recent months, helped by dollar deposit rates rising to above 3% (and up to ~4% at some smaller/foreign lenders) as China’s domestic yuan deposit rates at major state banks remain near 0.95%. The 10-year U.S. yield has climbed ~30 bps since early June to 4.76%, making Treasuries relatively more attractive versus low China government-bond yields and triggering a shift in bank strategy amid tighter scrutiny of offshore conversions. While Treasuries held via U.S. custodians fell 13% year-over-year to $633.4B in June (lowest since 2008), the data may understate true holdings. The reported inflows could dampen yuan appreciation pressure, though the impact on China’s overall Treasury position is unclear.

Analysis

The market read-through is less about a headline-level foreign buyer and more about a private-sector recycling of China’s surplus dollars into higher-yielding liquid assets. That creates a marginal bid for U.S. duration while also suggesting Chinese banks are absorbing FX receipts instead of forcing immediate yuan conversion, which is supportive for USD/CNH stability and a mild headwind to rapid yuan appreciation. The first-order impact on Treasury prices is likely small; the more durable effect is on term-premium psychology if this becomes a recurring source of non-official demand.

Second-order, the competitive pressure inside China’s banking system matters more than the Treasury flow itself. Banks that can mobilize dollar deposits cheaply will gain a spread advantage; institutions reliant on yuan funding may be forced to defend deposit bases at the cost of net interest margins. For onshore rates, this is another outlet for excess liquidity that helps prevent domestic yields from collapsing further, but it also reinforces a low-return environment that pushes capital toward offshore assets whenever regulators permit.

Contrarian take: this may be an FX-management tactic, not a conviction macro allocation. If the PBOC leans against dollar hoarding or if U.S. yields break lower on data, the flow can fade quickly and the market will discover the bid was too small to matter. The key falsifier over the next 1-3 months is whether USD/CNH keeps rising despite the deposit-rate changes; if it does not, the policy signal is weaker than it looks.

Key Decisions for Investors

• Tactically long IEF or TLT on yield spikes over the next 2-6 weeks; use the move as a small-duration hedge, not a core macro bet. Falsifier: 10Y UST yield holds above ~4.9% on stronger U.S. inflation/employment data.
• Initiate a small 3M USD/CNH call-spread position to express slower yuan appreciation rather than outright devaluation. Best entry is on any retracement in USD/CNH; cut if the PBOC reasserts a stronger fix or if capital-flow data improves materially.
• Do not chase Chinese bank beta on this alone; treat it as a watch item for deposit-rate competition, not an earnings inflection. If deposit competition broadens to the state majors, then revisit CMB/ICBC/HK-listed bank proxies as relative winners.
• Use rallies in U.S. rate-sensitive equities that depend on lower mortgage/discount rates as a hedge beneficiary basket only if the Treasury bid persists for several sessions. If the flow proves ephemeral, rotate back out quickly.
