### What is the Swap Curve?

Garabedian, Typically, the "swap curve" refers to an x-y chart of par swap rates plotted against their time to maturity. This is typically called the "par swap curve." Your second question, "how it ...

### Difference between OIS Rate and Fed Funds Rate

The OIS represents the cost of repeated overnight unsecured lending over periods of up to two weeks (sometimes more). Whether it is secured or not depends on which of the overnight rates it is linked ...

### Why using the swap curve as riskfree rate and no longer gov bonds?

I guess it depends on what they're referring to... The traditional swap curve (LIBOR-based) is certainly not risk free, as evidenced by the experience of the financial crisis and the resulting ...

### Why does the valuation of the floating leg of a swap only use the next payment?

The reason why you can price a swap without a model is because you can replicate the payoff using only zero-coupon bonds. For the fixed leg this is trivial. For the floating leg, at $T_0$ invest ...

### Use QuantLib Python to calculate Swap DV01

No, I'm afraid you're comparing apples with oranges. Your calculation of the DV01 of the swap is correct (with a caveat, see below), but the figure returned from ...

### Swap curve construction

I think your question can be split into two parts: (i) how to value a swap mathematically and (ii) how swaps actually work as a traded product. Part (i): As noob2 pointed out, "theoretically"...

### What is the difference between OIS Swap vs Basis Swap?

A Basis swap is a broad category of swaps where you exchange one floating rate against another floating rate. Without knowing the specific rates involved it is difficult to say more. An OIS Swap is ...

### interest rate swap: PV01 vs DV01

In traditional terminology PV01 is 'present value of a basis point' and DV01 is 'dollar value of a basis point' which are technically only different in different currencies. Bloomberg has decided to ...

### Why are multiple custom curves (swap) built for one desk?

Chapter 1: Goldilocks is ousted by the bears Once upon a time, the banks used a fixing called LIBOR as a measure of the risk-free interest rate. Then the big hairy crisis came along and ate all our ...

### Carry calculation on an interest rate swap

I will attempt to summarise the content included in this book, which has a specific chapter dealing with carry and roll-down. There, two concepts are made completely separate. Costs-of-carry are ...

### SOFR Discount Curve Construction in Nov 2021

Fixed vs SOFR swaps for longer maturities are very liquid, since the interbank market trades these directly now, and these are the best instruments to construct the long end of the curve (2yr to 50yr)....

### Does an Interest Rate Swap has a Vega component?

There is no contradiction. If the strike of the floor and cap are both equal to the swap rate, and all accrual/payment frequencies, etc. are the same, then put-call partiy implies C_{t}-F_{t}=S_{t},...

### Difference between OIS Rate and Fed Funds Rate

Secured and unsecured refers to lending. However OIS is a swap based on FF, not a loan. It is a different animal. So OIS is a derivative, or a bet, based on the average of future (unsecured) FF rates ...

### Carry calculation on an interest rate swap

It turns out that the two things are the same, appropriately scaled. Proof: we can construct a 5 year swap using 3 month libor combined with a 3mo-4.75yr forward swap, weighted by the dv01s of each ...
Accepted

### Why are Interest Rate Swaps not valued using Monte Carlo Simulations?

Forward rates are determined from current spot rates bootstrapped from traded instruments. The reason is that if the forwards were different from the ones inferred from the spot rates, there would be ...

### Curve Euribor - Euribor 3M

It is incorrect to use 1m euribor or O/N euribor in a 6m Euribor forward curve. You should only use instruments based on 6M euribor, such as 1x7 FRA, 6x12 FRA or swaps v 6m Euribor, as you have done ...

### What is the correct convexity adjustment for an Interest Rate Swap with unnatural reset lag?

Consider a date sequence \begin{align*} 0 \leq t_0 \leq T_s < T_p < T_e, \end{align*} where $t_0$ is the valuation date, $T_s$ is the Libor start date, $T_p$ is the payment date, and $T_e$ is ...

At most banks, swaption traders have models that allow non atm volatilities to be controlled by two parameters. Specifically , a parameter to control the smile (richness of out of the money options) ...
