Public financial experiments

Choose a financial question, read its assumptions and open the working experiment. All 16 experiments below run without signing in. Starting figures are illustrative and editable.

• Rate cuts and net financing cost

  Can a policy-rate cut increase net financing costs when credit spreads widen?

• Yield shock and bill value

  What is the mark-to-market effect of a yield change before a bill matures?

• Ladder versus single maturity

  How does spreading maturities change available cash before a payment?

• Fixed versus floating debt

  Which borrowing structure has lower interest cost under this explicit rate path?

• EUR payable funded from USD

  How much USD is required to fund a EUR payment after a currency move?

• Late customer payment

  Can an otherwise profitable business meet its obligation if a receipt is late?

• Sufficient assets but insufficient available cash

  Do redemption proceeds arrive before the payment deadline?

• Two accounts sharing one institution

  How much payment capacity survives a shared institution outage?

• Minimum liquidity buffer

  What initial cash exactly covers the deepest deficit in this deterministic payment schedule?

• Smallest searched shock causing failure

  At what haircut on this finite grid does available liquidity fail to cover the obligation?

• Stablecoin redemption routes

  Can market-sale and delayed par-redemption proceeds fund a dollar payment when the token trades below its assumed peg?

• Gas funding and confirmation deadline

  Do the fee cap, native-token budget and declared confirmation schedule all permit a transaction before the deadline?

• Net yield after all declared costs

  Does flat assumed yield cover entry, gas and exit costs over the chosen holding period?

• AMM divergence versus holding

  How does a fee-free 50/50 constant-product liquidity position differ from holding its original two assets after a token-price change?

• Treasury repo margin threshold

  When does repriced Treasury collateral trigger a cash margin transfer after repo interest, a contractual threshold and a minimum transfer amount?

• Treasury clean and dirty settlement price

  How much does accrued coupon interest add to a quoted clean price at Treasury settlement?
