GLOBAL INTEREST RATE SWAP NOTIONAL OUTSTANDING

None of this exists on Canton. Until now.

THE COUNTERPARTIES

Every swap has two sides.

Fi SETTLEMENT FIXED ORBIT — PREDICTABLE VARIABLE PATH
FIXED ORBIT
THE POSITION

A Canton lending market borrower pays a floating rate. This month: 6.8%. Last month: 9.1%. Next month: unknown. The CFO needs a number they can budget against.

WHAT THEY WANT

A fixed rate. Lock in 7.4% for 90 days. Pay the same number every settlement period regardless of what the market does.

THE SWAP

They enter Fixium as the fixed-rate receiver. Notional agreed. Tenor set. Fixium matches them with a counterparty. Their identity and notional stay private on Canton.

SETTLEMENT

Rate for the period averaged 9.2%. They pay 7.4%. The net difference flows to them — 1.8% × notional × (90/360). Their cost was fixed exactly as planned.

VARIABLE PATH
THE POSITION

A yield optimizer holds excess capital on Canton. Current floating rates are attractive. They believe rates will rise and want to capture the upside without running a lending desk.

WHAT THEY WANT

Floating rate exposure. Pay a fixed 7.4% and receive whatever the market rate is over the period. If rates rise to 10%, they capture the spread.

THE SWAP

They enter Fixium as the floating-rate receiver. Same notional, same tenor. The match is made. Neither party sees the other's position size.

SETTLEMENT

The same 1.8% spread flows to them. They paid 7.4% fixed and received 9.2% floating. Settlement was atomic, instant, and private.

Settlement = (r_float − r_fixed) × N × (Days / 360)
SETTLEMENT MECHANICS

The math is not complicated. The execution is.

FIXED LEG

The fixed-rate payer agrees to pay a defined percentage of the notional for the tenor of the swap. This payment is known at inception and does not change.

r_fixed × N × (T/360)
FLOATING LEG

The floating-rate payer pays the realized rate from Canton's reference markets over the period, calculated as the average sampled at defined intervals. Not known at inception.

r_float_avg × N × (T/360)
NET SETTLEMENT

At maturity, only the net difference is exchanged. No principal changes hands at any point in the swap lifecycle.

(r_float_avg − r_fixed) × N × (T/360)
SETTLEMENT SIMULATOR

Set the terms. The fixed leg stays flat; the floating leg moves with the market. Only the net difference settles.
