Recently, we studied the branching ratios of rare K and B decays in models with Minimal Flavor Violation (MFV) using the presently available information from the universal unitarity triangle analysis and from the measurements of Br(B -> Xs gamma), Br(B -> Xs l+l-) and Br(K+ -> pi+ nu nubar). We analyzed in detail possible scenarios with positive or negative interference of Standard Model (SM) and New Physics contributions. In particular, we derived upper bounds on various rare decays and pointed out an interesting triple correlation between B -> Xs gamma, B -> Xs l+l- and K+ -> pi+ nu nubar present in MFV models.
