Moody’s strips U.S. of triple-A credit rating

Market impact and bond mechanics

• Some expect limited immediate market impact; big funds typically require “two of three” AAA ratings, so prior downgrades already forced any rule-based selling.
• Others note that after the 2023 downgrade, stocks fell and Treasury yields rose; contrast with 2011 when borrowing costs actually dropped amid a “flight to quality.”
• Several point out that downgrade = bad macro news, which can either push investors into Treasuries (lower yields) or, if confidence erodes, out of them (higher yields).

Role and value of rating agencies

• Many are skeptical of Moody’s after its role in the 2008 crisis, asking why anyone still listens.
• Defenders argue their ratings are statistically informative overall and still widely embedded in regulation, mandates, and “cover your ass” institutional behavior.
• Some stress agencies rate solvency, not liquidity; AAA mortgage tranches mostly paid out, even if they traded disastrously in 2008.

US fiscal path: deficits, debt, and politics

• Broad agreement that current US debt/deficit trajectory is problematic; disagreement over timing and severity of the risk.
• One camp blames persistent tax cuts (especially recent ones) and resistance to raising revenue; another insists “reduce spending” is the only honest answer.
• There’s bipartisan pessimism about political will: no constituency wants cuts to Social Security/Medicare, welfare, or defense, and tax hikes are toxic.

Taxes, inequality, and entitlements

• Multiple comments highlight extreme wealth concentration and argue to “tax wealth, not work,” including wealth taxes, closing loopholes, limiting stock-collateral borrowing, and discouraging buybacks.
• Proposals to means‑test Social Security draw fire: critics say it adds bureaucracy, undermines universal support, and retroactively breaks promises; supporters argue high earners don’t need full benefits.
• Others prefer lifting or removing the Social Security payroll cap rather than means‑testing.

Money printing, inflation, and default

• One side: US can always pay dollar debts by issuing currency, so default risk is political (“won’t pay”), not financial (“can’t pay”); downgrade reflects trust/governance risk.
• Opponents counter that inflating away debt is effectively a partial default; serious money‑financed spending would wreck the dollar, spike yields, and trigger a debt or inflation spiral.
• Debate over whether past high-debt periods show current worries are overstated, or whether today’s combination of higher rates + much larger debt/GDP is genuinely new.

Geopolitics, leadership, and alternatives

• Several link the downgrade to perceived US political instability and trade/tariff policy, not just raw debt ratios.
• Some argue the US has squandered its role as architect of the global system, opening space for other powers and alternative payment networks.
• Others think US assets still dominate because there is “nowhere else for the money to go,” but warn that any shift will be “slow, then sudden.”

Public vs private debt; theoretical frames

• A minority emphasizes that government debt is the private sector’s asset and suggests private‑sector over‑indebtedness is the real systemic risk.
• Others insist that, practically, rising interest costs crowd out other spending and still end up on taxpayers’ backs.
• Two conceptual camps emerge:
  • “Dollar milkshake” view: global demand for dollar collateral makes US debt unusually sustainable.
  • Traditional fixed‑income view: at some point investors will demand higher real returns or rotate away, regardless of dollar dominance.

Everyday consequences

• For laypeople, commenters highlight:
  • Likely higher long‑run tax burden due to growing interest costs.
  • Potential cuts or restructuring of benefits if politics eventually turns to consolidation.
  • General increase in economic and political instability if markets begin to doubt US fiscal and institutional reliability.
