What is the OIS curve?

What is the OIS curve?

OIS curves became the market standard for discounting collateralized cashflows. This curve represents the market expectations of the Federal Reserve daily target for the overnight lending rate. As such the fed funds rate and OIS rate are the relevant funding rates for collateralized transactions.

Why is OIS risk free?

The OIS rate is generally considered to be a good proxy for a term risk-free rate, and is therefore less risky than the corresponding IBOR, because there is less credit risk associated with it due to the parties to an OIS not being required to exchange the principal amount during the life of the transaction and only …

How does OIS swap work?

An Overnight Index Swap (OIS) is an interest rate swap agreement where a fixed rate is swapped against a pre-determined published index of a daily overnight reference rate for example SONIA (GBP) or EONIA (EUR) for an agreed period.

What does Libor OIS spread indicate?

The LIBOR-OIS spread represents the difference between an interest rate with some credit risk built-in and one that is virtually free of such hazards. Therefore, when the gap widens, it’s a good sign that the financial sector is on edge.

Why OIS is better than LIBOR?

The major reason for switching from using LIBOR to the OIS as a term structure for pricing interest rate swaps is that OIS discounting better reflects the counterparty credit risk in a collateralized interest rate swap. Due to these developments/ requirements, the credit risk on swaps has reduced significantly.

Why is Sonia lower than base rate?

SONIA is lower than LIBOR because it does not include the credit/liquidity risk premium noted above. Lenders are therefore likely to increase the margin or add a “credit adjustment spread” to cover the difference.


The volumes underlying SOFR are far larger than the transactions in any other U.S. money market. This makes it a transparent rate that is representative of the market across a broad range of market participants and protects it from attempts at manipulation.

Why is OIS lower than LIBOR?

The fixed rate of OIS is typically an interest rate considered less risky than the corresponding interbank rate (LIBOR) because there is limited counterparty risk. The spread between the two rates is considered to be a measure of health of the banking system.

Why is LIBOR OIS spread widening?

Right now it boils down to deteriorating market sentiment about credit and recession risks rather than a genuine fear of a pullback in funding markets. The perceived added risk means banks will demand higher interest payments to lend to one another — hence the increase in the spread.

Is OIS secured or unsecured?

Second, Libor is an unsecured financing rate, while fed funds, or the overnight index swap (OIS), is based in a risk-free rate.

How do you price OIS?

The fair price (present value) of any stream of cash flows is the sum of their fair prices, provided that any non-linear contributions are considered too small to be taken into account. Therefore the price today of an OIS is just the sum of the prices of the fixed and floating cash flows.

Is SONIA Annualised?

The rate conventions are: annualised rate, act/365, four decimal places. In 2018, SONIA (floating rate) bonds accounted for 20.7 per cent share of UK issuance compared to 48.1 per cent share of Interbank Offered Rate (floating rate) bonds.

Which is an example of dual curve bootstrapping?

This example draws from the following papers and journal articles: [1] Ametrano, F, and Bianchetti, M., Everything You Always Wanted to Know About Multiple Interest Rate Curve Bootstrapping but Were Afraid to Ask (April 2, 2013), available at: [2] Bianchetti, M.,

How to bootstrap a discount curve using a forward curve?

This example shows how to bootstrap a forward curve using a different curve for discounting. Data is needed for both the forward and discount curve. For this particular example, it is assumed that the data is provided for EONIA (the discount curve) and EURIBOR (the forward curve).

How is the OIs and LIBOR curve constructed?

Accurate construction of the OIS and LIBOR curves involves assembling market prices from a variety of instruments, including cash deposits, swaps, and futures or forward rate agreements, prior to bootstrapping. This is because each instrument is only specified and traded for a particular time segment across a 30+ year curve.

How are interest rate swaps valued on a dual curve?

Parties on either end of a swap pay or earn overnight rates on posted collateral. But interest rate swaps are still largely negotiated using an interbank rate such as LIBOR. This requires a second set of discount factors to be derived in order to correctly value swaps, hence the term dual curve stripping.
