Key takeaways

  • Concerns about a 'Treasury-Fed accord 2.0' are overstated because liquidity injections to stabilize funding strains already resemble fiscal dominance and Treasury issuance choices can offset Fed balance-sheet decisions.
  • The appropriate regional rotation framing is 'buy the Americas' rather than 'sell America,' treating Latin America as a complementary beneficiary of US growth and supply-chain reorientation.
  • A baseline tariff regime of roughly 10–15% on most non-China US trade partners and 30–35% on China will likely persist for years and survive a future Democratic administration.
  • There is no coherent US 'weak dollar' grand strategy, and markets are over-interpreting documents as evidence of an active dollar-devaluation policy.
  • Policy should aim to raise money velocity by enabling banks to lend rather than expanding monetary aggregates while velocity falls, and since the GFC M2 and velocity have appeared inversely related.

Fed Plumbing Repo Tail Risk And Regulatory Constraints

  • Concerns about a 'Treasury-Fed accord 2.0' are overstated because liquidity injections to stabilize funding strains already resemble fiscal dominance and Treasury issuance choices can offset Fed balance-sheet decisions.
  • The standing repo facility has been ineffective in practice because stigma and channel design prevent it from reaching the marginal funding demander (hedge funds).
  • Separating bank supervision/regulation from monetary-policy implementation has been harmful because reserve additions used to stabilize funding markets effectively become monetary policy.
  • A core post-2019 funding-market problem persists because hedge funds and primary trading firms drive the upper tail of repo rates while bank balance sheets remain constrained by regulation.
  • Banks hold roughly $3 trillion in reserves largely due to regulatory requirements and supervisory preferences for reserves over other comparable HQLA, and easing could reduce reserve hoarding over time.
  • Ending QT and restarting reserve-management operations was necessary because repo conditions in November were unusually stressed and risked a headline-making spike.

Americas Nearshoring And Latam Relative Advantage

  • The appropriate regional rotation framing is 'buy the Americas' rather than 'sell America,' treating Latin America as a complementary beneficiary of US growth and supply-chain reorientation.
  • Latin America can support advanced manufacturing as a lower-cost alternative to the US while maintaining a well-educated labor base and fewer labor-rights concerns than some Asian supply-chain hubs.
  • Latin America is positioned as a relative geopolitical and macro winner due to proximity to the US, resource endowments, manageable exposure to Middle East maritime chokepoints, and reserve-building via current-account surpluses.
  • US-linked growth and FDI are likely to funnel more toward Latin America, potentially driving currency appreciation and a multi-year regional investment renaissance.
  • A Washington regime shift toward greater openness to crypto and neobanks could allow Latin American fintechs to expand into the US via cross-border customer overlap.

Geopolitics Regional Spheres And Tariff Persistence

  • A baseline tariff regime of roughly 10–15% on most non-China US trade partners and 30–35% on China will likely persist for years and survive a future Democratic administration.
  • The global economy is shifting toward competing regional spheres where natural resources and supply-chain resilience have higher strategic and market value.
  • China’s use of rare earths as leverage has accelerated US efforts to rebuild supply chains domestically and in the near abroad, and the US position is materially improved versus a year ago.
  • A doctrine prioritizing US influence and economic integration across the Americas is likely to persist for years and could continue under a future Republican administration.

Policy Process And Narrative Disputes Fx And Geopolitics

  • There is no coherent US 'weak dollar' grand strategy, and markets are over-interpreting documents as evidence of an active dollar-devaluation policy.
  • Recent US actions in Iran and Venezuela are not primarily an anti-China strategy, even if they incidentally disadvantage China on energy access and terms.
  • US policy actions tend to occur when the president prioritizes an issue or when a small set of principals align and elevate a proposal, rather than by strict adherence to strategy documents.

Ai Productivity Fiscal Dynamics And Future Rate Sensitivity

  • Policy should aim to raise money velocity by enabling banks to lend rather than expanding monetary aggregates while velocity falls, and since the GFC M2 and velocity have appeared inversely related.
  • Monetary-policy transmission may strengthen over the next 5–10 years if the economy shifts toward more bank lending and physical capital deepening, making future hiking cycles more recessionary than the recent one.
  • AI-driven productivity could alleviate US fiscal and demographic pressures by boosting real growth without proportionate unit labor cost increases, potentially extending US exceptionalism if outcomes are between extremes.

Unknowns

  • What specific tariff schedules, exemptions, and enforcement practices (including sectoral carve-outs) are actually implemented over the next 12–24 months, and do they persist across political cycles?
  • What measurable changes occur in rare earth and other critical-mineral supply chains (permitting, refining capacity, offtake agreements, import concentration) that would substantiate an improved US position versus a year ago?
  • What observable indicators validate the proposed US policy decision model (presidential prioritization and aligned principals) versus a document-driven strategy process?
  • Is there evidence in official communications or coordinated actions that supports or refutes the claim that there is no coherent weak-dollar strategy?
  • Do realized cross-asset correlations and cross-country dispersion behave as claimed during subsequent physical versus policy shock episodes?

Investor overlay

Read-throughs

  • Funding market stress is likely to show up first as repo rate tails and ad hoc liquidity operations, driven by constrained bank balance sheets and leveraged nonbank activity. Distinguish plumbing actions from true stance shifts by tracking persistence and breadth of operations.
  • Regional allocation narrative may favor within hemisphere dispersion rather than a simple sell America framing, with Latin America positioned as a complementary beneficiary of US growth and supply chain reorientation. Impact depends on observable follow through in trade and investment channels.
  • Tariffs may function as a durable regime rather than a short term tool, shaping sector and country dispersion through supply chain rebuilding and critical minerals focus. Market narratives about an intentional weak dollar strategy may be overstated versus a process driven policy model.

What would confirm

  • Recurring repo market volatility and repeated reserve management operations despite stable growth inflation data, alongside signs that existing facilities are underused, consistent with stigma or channel frictions rather than a single shock event.
  • Clear implemented tariff schedules with limited exemptions and consistent enforcement over 12 to 24 months, plus indications of persistence across political cycles, supporting the view of tariffs as a lasting regime.
  • Measurable improvements in US critical mineral supply chain position versus a year ago, such as permitting progress, new refining capacity, offtake agreements, or reduced import concentration, aligning with the strategic supply chain rebuild framing.

What would kill

  • Sustained repo stability with no meaningful tail events and minimal need for repeated liquidity operations, undermining the claim that structural balance sheet constraints are driving persistent funding fragility.
  • Tariff rates meaningfully revert toward prior norms or enforcement becomes broadly lax through widespread carve outs, indicating the higher tariff regime is not durable.
  • Official communications or coordinated actions that explicitly target currency devaluation, contradicting the claim that there is no coherent weak dollar strategy and that markets are over reading document narratives.
