Former Treasury Secretary Henry M. Paulson Jr. has urged policymakers to develop contingency 'break-the-glass' measures should demand for U.S. Treasury securities collapse, according to the MarketWatch report. While the article captures Paulson's call for preemptive planning informed by his experience steering the 2008 financial crisis, it underplays the deeper interplay between unsustainable fiscal trajectories, evolving global reserve currency dynamics, and liquidity risks in the Treasury market that have surfaced in multiple prior stress episodes.

Primary documents illustrate the scale. The Congressional Budget Office's 2024 Long-Term Budget Outlook projects federal debt held by the public rising from 99 percent of GDP in 2024 to 166 percent by 2054 under current law, driven by interest costs, entitlement spending, and persistent primary deficits (CBO, June 2024). This path contrasts with the post-World War II period when debt ratios declined steadily amid higher growth and lower rates. The U.S. Treasury's TIC data for 2023-2024 further shows foreign official holdings plateauing, with China reducing its Treasury portfolio by over $200 billion since 2021 peaks amid bilateral tensions, while Japan has become the largest holder through interventions to support the yen.

These trends connect to patterns seen in related events. During the March 2020 COVID market turmoil, the Federal Reserve invoked emergency facilities and purchased $3 trillion in Treasuries and MBS to restore liquidity when dealer intermediation capacity was overwhelmed, as detailed in the Fed's Financial Stability Report (various issues, 2020-2024). The 2013 taper tantrum and the 2022 UK gilt crisis demonstrated how abrupt shifts in yield expectations can cascade, even in advanced markets. The original MarketWatch coverage misses these liquidity feedback loops and the role of quantitative tightening since 2022, which has removed the Fed as the marginal buyer and increased reliance on private demand at a time when annual issuance exceeds $2 trillion.

Multiple perspectives emerge from primary sources. The Federal Reserve's semiannual Financial Stability Reports consistently flag elevated vulnerabilities in Treasury market liquidity under stress but note that the dollar's reserve status and safe-haven flows have so far underpinned demand. In contrast, the Bank for International Settlements' Annual Economic Report (2023) and related papers highlight growing fragmentation in the international monetary system, including BRICS initiatives for non-dollar trade settlement and central bank gold accumulation as partial hedges. CBO Director Phillip Swagel has testified that rising debt could eventually raise risk premiums, while former officials like Lawrence Summers have echoed concerns about fiscal dominance potentially constraining monetary policy.

What mainstream reporting often gets wrong is treating Treasury demand collapse as a remote tail risk rather than a plausible scenario triggered by combined fiscal, monetary, and geopolitical shocks. Paulson's 2008-era experience with ad-hoc interventions (TARP legislation and Fed facilities) suggests that waiting for crisis conditions reduces policy space. A synthesized reading of the CBO outlook, TIC statistics, and Fed stability reports indicates that contingency planning could involve pre-authorized liquidity backstops, expanded standing repo facilities, or even consideration of yield curve control mechanisms last used during World War II, each carrying trade-offs around moral hazard and inflation expectations.

The warning thus serves as a lens on longer-term questions of U.S. fiscal credibility and the durability of dollar hegemony, without implying imminent crisis. Both optimistic views (no viable alternatives to Treasuries) and cautionary analyses (rising debt-service ratios approaching 4 percent of GDP by 2034 per CBO) warrant equal weight in policy discussions.
