Here is a 16-line English summary of the conspiracy theory you outlined:

1. **The goal**: Ensure the successful settlement and adoption of OUSD.
2. Upon OUSD’s launch, a massive purchase of short-term U.S. Treasury bills is required.
3. The aim is to buy these as cheaply as possible — meaning yields must be high.
4. The U.S. government, meanwhile, wants to buy long-term bonds at the lowest possible prices to save on dollar costs.
5. To achieve this, it keeps signaling rate hikes while sustaining strong oil prices.
6. Starting September 9, the Treasury begins purchasing long-term bonds directly.
7. This creates downward pressure on long-term yields, allowing government purchases at a discount.
8. At the same time, the Treasury issues large volumes of new short-term bills to refinance long-term debt.
9. These short-term issuances also serve general fiscal financing needs.
10. With short-term supply surging, short-term yields rise sharply.
11. OUSD, needing to deploy enormous cash reserves, steps in to buy those short-term bills.
12. This gives OUSD high-yielding, safe assets right at launch.
13. The government locks in low long-term rates while OUSD absorbs the expensive short-end paper.
14. Oil strength and rate-hike rhetoric keep inflation expectations elevated, forcing short-term yields higher.
15. The coordinated timing (Sept. 9) suggests a pre-arranged dual operation.
16. In short, the government dumps short-term debt to OUSD while silently accumulating cheap long-term debt — a hidden swap benefiting both, but dressed as market forces.
