New Treasury issuance forces GSIBs to pre-fund cash, not signal a liquidity crisis. All new Treasuries go first to the nine GSIBs, who are obligated to buy at auction; ahead of a big offering they raise cash by lending securities overnight in the repo market (SOFR), pushing SOFR above the Fed's IORB rate.
Last week's SOFR spike to ~29bps over IORB tracked a $125B Treasury offering, not a funding crunch. The Nov 4-6 3/10/30-year auctions totaled $41B, $41B and $43B; social-media "doom" posts framed the SOFR jump as a great-financial-crisis-style liquidity shortage.
SOFR fell back below the Fed funds rate the day after settlement (Nov 6), confirming the cash-accumulation explanation. The author argues this pattern — banks stockpiling cash ahead of mandatory GSIB purchases — will recur with future large issuance and urges watching the "plumbing" rather than trusting alarmist commentary.
Private letter ratings run 2.74 notches higher on average than NAIC's own SVO designations. Small raters (Egan-Jones, HR Ratings, Kroll, Morningstar) issue ~7,000 private letter ratings against ~1,000 from Moody's/S&P/Fitch combined; 79% of re-ratings move higher, some by more than six notches, letting insurers book investment-grade capital treatment on debt that isn't.
US insurers hold roughly 35% of assets in private credit — CRE, private placements, residential mortgages, ABS, mid-market lending, and infrastructure — a far deeper concentration than the rest of the world, while loans (unlike bonds) carry no ratings requirement, so the private letter system fills the gap the big three agencies don't cover.
The inflated ratings amount to capital arbitrage: a higher notch means less reserve capital required by law. Global Atlantic (KKR-owned), MassMutual, and Brookfield hold 55% of the highest-rated private letter bonds; following Tricolor and First Brands' collapses, the author reads this as evidence of systemic fraud risk despite bank claims the failures were "one-offs."
The SNB's $167B tech-heavy US stock stake is currency management, not investment. Built from an $855B balance sheet that includes $42B across Amazon, Apple, Meta, Microsoft and Nvidia, the position exists because Switzerland printed francs during COVID and bought foreign stocks/bonds instead of its own bonds, to avoid pushing already-low Swiss rates negative — a pattern analysts now call "foreign quantitative easing."
Repatriating the portfolio is structurally blocked by the e-franc. Since the francs used to buy foreign assets have no matching physical franc, selling those assets and buying francs to bring money home would spike the currency (deflationary for an export economy) and risk negative rates — the exact outcomes the SNB is trying to avoid; the franc is already up 15% against the dollar since the author's earlier coverage, eroding the portfolio's franc-denominated return.
This differs from Japan's carry-trade risk, where the BOJ holds its own currency's assets. The author flags a scenario where yen weakness forces Japan to choose between raising rates (breaking its fiscal position) or letting the yen fall, potentially triggering sales of Japan's $1.1T in US Treasuries and $900B in foreign stocks/bonds — a risk distinct from Switzerland's, where the SNB, owned by cantonal banks, has no clean mechanism to unwind its position at all.
US tariffs now average 22.5%, above the Smoot-Hawley levels the author links to the 1930s global depression. He frames this as context for the Marin paper's proposal to use presidential emergency powers rather than multilateral negotiation to weaken the dollar.
The paper proposes an IEEPA-based "user fee" on foreign sovereign holders of Treasuries, avoiding the word "tax" to sidestep tax treaties. It would start small (1%) and escalate, withhold interest payments, hit geopolitical adversaries like China harder than allies, and leave private-investor holdings untouched — the goal being to make reserve accumulation less attractive without provoking a sell-off.
The paper itself warns the fee could spark reserve selling, a dollar rout and a rate spike, and it requires the Fed's "voluntary cooperation." The author notes China's rare-earth-minerals leverage complicates differentiated treatment, and reads the plan's reliance on Fed deference as Trump effectively setting the yield curve, since the Treasury Secretary reports directly to him.
