### Duration of a floating rate bond with spread

Is formula (1) correct? Yes, follows from first definition - floater with deterministic spread is composed (sum) of two components: (1) pure floater and (2) deterministic coupon strip via contractual ...

### Expected Cash flows of a Floating Rate Note

If you are trying to value the FRN, plugging in the forward rates and then discounting is a method that works. If you are trying (as you specifically say) to calculate the expected cash flows, then ...

### Calculating discountmargin using flat yield

I am a co-author of that paper. You may want to check out FinancePy which is a beta version of a finance library where I have implemented the code for calculating the discount margin. Here is an ...

### Can I use spot rates bootstrapped from a swap curve to price a bond?

The general - and short - answer would be no: Except for some hypothetical cases, unless you have a convincing model for the residual spread-over-swap, you cannot use swaps to value your bond. Quick ...

### How does Bloomberg arrive at FRN Total Price?

I may be missing something, but I think you're overcomplicating it. You don't need discount margin and all that jazz. The clean price (entered in upper left corner) is 100.311% The face value (...

### How is Bloomberg's fixed-equivalent yield on a floater calculated?

Quote [fixed equivalent] yield is determined by assuming the coupon rate on the floater is swapped to a synthetic fixed rate and then solving for the internal rate of return. Endquote link In other ...

### How to interpret YTM of FRN when interest rates change?

While this sounds like a basic question, it does bring up a few nuances that are worth discussing. First, suppose you have a fixed-coupon bond, rather than FRN. When risk-free rates go up, the coupons ...

Let's stick with first principles and assume a single-curve world. Assume a discount factor curve $D_i\equiv D(t_i), t\geq 0, D(0)=1$. The risk-neutral expected forward rate from $t_i$ to $t_{i+1}=t_i+... 1 vote ### falling flatforward curve in quantlib Set the interest rate in the FlatForward construction to be ql.Compounded or ql.Continuous. ... 1 vote ### Is this simple model used to calculate the interest rate duration and credit duration of a floating rate note? Other models? I don't have enough repuation to commnet, but I think it is a general cashflow discount model for bond pricing, and the formula looks wrong. The last item should be discounting of principal and last ... 1 vote Accepted ### Calculating discountmargin using flat yield I think you mean this: Another DM variant is this: Source: This document has numerical examples. 1 vote ### How does the yield of a floater change when the discount/required margin changes? This is not how most people calculate the yield of a floater. The way most people calculate the yield of a floater is: 1 for each remaining unset coupon, project the values of the index that will be ... 1 vote ### Do floating rate bonds always trade near par? A floating rate bond trading at par is more like an academic formulation rather than what you would observe in reality. If there were only one yield curve and the bond has no credit spread, that in ... 1 vote ### Calculating YTM for a floating rate bond The yield is the internal rate of return of the coupons and the principal repayment. For a floater, the future unset coupons are not known, and the value of the yield depends a lot on how you project ... 1 vote ### For a Floating Rate note, is there a way to convert the Discount Margin into OAS or Price? If you use Python, check out this example notebook on FinancePy https://github.com/domokane/FinancePy/blob/master/notebooks/products/bonds/FINBONDFRN_CitigroupExample.ipynb The function you need is ... 1 vote ### Valuing an interest rate swap using a par swaps curve? My understanding is as follows - you pay 100 at$T=0$, receive LIBOR+40bp annually, and get back 100 at the end of the deal. This is actually a cash outflow of 100, plus a floating rate note (FRN). ... 1 vote ### Zero Coupon Curve and Floating Rates Notes pricing The website below shows how to price bonds from curves, currently it only supports fixed rate and zero-coupon bonds, but it might give you an idea how to price a floater using similar concept: Goto: ... 1 vote ### Calculating Discount Margin on a floating rate bond using QuantLib Update (2018-10-09): This solution is more correct. It's a class that solves for the DM using the class ForwardSpreadedTermStructure. ... 1 vote ### book of options hedging case of floating rate The question of how to hedge an option portfolio on multiple underlyings against tail risks is not an easy one, nor what with a single answer. There are probably two big risks: - a period of ... 1 vote ### Pricing a Vanilla swap between coupons; What rates to use? Linear interpolation of the discount factors is not a good idea. A better idea, in the absence of a full analysis, is to linearly interpolate the logarithm of the discount factors. You can use the ... 1 vote ### Do FRN's *always* trade on par on reset days, regardless if the issuer's credit quality has changed? your concern about issuer's credit quality deterioration is valid. price would be par when a spread over reference index for the purpose of coupon determination is the same as a spread used for ... 1 vote Accepted ### What is the yield when a floating-rate note is issued above/below par? Yes, you would make "guesses", but fortunately these guesses are derived from market-observed rates. Assuming a semi-annual coupon rate and discrete compounding, the price of a bond ($P\$) is given ...
