Yield Curve Mambo

A swaps dealer is typically one of the counterparties. Swaps dealers hedge their risk by entering into some transactions where they pay a fixed rate and others where they pay a floating rate. The dealers profit from the difference between the fixed rate they are willing to pay and the fixed rate they demand.

If interest rates subsequently rise, pushing floating rates higher, the fixed-rate payer obtains additional savings at the expense of the floating-rate payer. Conversely, if rates move lower, the floating-rate payer obtains additional savings at the expense of the fixed-rate payer

swaps and swap spreads
An interest-rate swap is a transaction between two so-called counterparties in which fixed and floating interest-rate payments on a notional amount of principal are exchanged over a specified term. One counterparty pays interest at a fixed rate and receives interest at a floating rate (typically three-month Libor). The other pays interest at the floating rate and receives the fixed-rate payment.

Widening credit spreads indicate growing concern about the ability of corporate (and other private) borrowers to service their debt. Narrowing credit spreads indicate improving private creditworthiness

can someone explain to me what it means?

Excellent!
Now that's the way to monitor flow over time!
Superb work, this must have taken ages to get together despite being only 1.30 long.
10/10 especially for the music.

Fantastic Nick!
