Hi Piter, first thing would be to get the Brazilian InflationIndex set up. If you look at UKRPI and the YY- versions that should be direct. However, please check carefully that the current setup does capture the relevant aspects of the Brazilian inflation index. The way to check what you need (as I'm sure you know) is to look at the termsheets from some of your c/ps and look at the fixing definition. Second thing is that it looks like there is interest in having bond bootstrapping in the library. Then you can do true real rate as well as breakeven version (there is a basis between them). Now, as you mention, getting a swap curve from that requires "trader input", i.e. an estimate of the bond-swap basis. This is generally proprietary. Hence, we could probably do with a spreaded version of the zero inflation curve. Comments anyone?

The base products are inflation Bonds (NTNB if you know Brazilian market). >From a group of NTNB I bootstrapd a zero real rate curve (Brazil trading is all about real rate), a inflation forecast (called breakeven, a simple non-arbitrage spread for a credit modelling team) and a Swap curve. The Swap was trick because there isn't liquidity, so the trader would like to use the NTNB yields +- some spread by bond and create a zero curve whose nodes were the bonds duration. I made a little bit different, using NTNB yields +- some spread but bootstrapping a zero curve from it. They told that "now they have a Swap curve". Well, that said, I don't know anything about inflation products in other countries but I would like to help you to test and enhance QuantLib for Brazilian inflation products. I would, at least, write some testsuites. Could you let me know if there is something I can do to help?
