Perhaps this question is more relevant to Quantitative Finance?

Thanks - didn't realize there was a quantitative finance stack exchange. Posted here as well: http://quant.stackexchange.com/questions/21959/data-source-for-a-corporate-bond-yield-curve

You're not supposed to cross-post between multiple StackExchange sites, so I'd suggest deleting this one: http://meta.stackexchange.com/questions/64068/is-cross-posting-a-question-on-multiple-stack-exchange-sites-permitted-if-the-qu

Data source for a corporate bond yield curve?

# Data source for a corporate bond yield curve?

(Asked by: username_0 on 2015-11-27)

[Yield curves](https://en.wikipedia.org/wiki/Yield_curve) are a valuable tool for economic analysis. It is particularly interesting to analyse the difference between Government Debt yields and Corporate Debt yields (credit spreads). This gives insight into confidence within the financial markets and economic health in general.

The government yield curve is easily accessible [here](https://www.treasury.gov/resource-center/data-chart-center/interest-rates/Pages/TextView.aspx?data=yield) but corporate yields are more difficult. I need a curve built from an index which gives an indication of the whole market.

There are some datasets available on [quandl](https://www.quandl.com/search?query=corporate%20bond%20yields) which give yields for different types of bonds. The [S&P 500 Bond Index](http://us.spindices.com/indices/fixed-income/sp-500-bond-index) provides some good perspective on S&P 500 bonds. I can't find anything though that gives an indication of either corporate bond prices or yields at different maturities. The maturity breakdown is needed to build a yield curve.

Does anyone know where corporate bond yield curve data (corporate bond index yields/prices by maturity) is published for free? I'm particularly interested in XML/JSON resources.
