Complete noob (in both FinTech and Blockchain), but in my limited experience in FinTech, if you could eliminate the need for the trusted nth party (Bank Of New York, for example, cleared all of the bond trades we made), then you could save a few 1/32's of a trade (my last client in FinTech was like 15 years ago so I don't even know if those fees are even valid anymore). In any case, as you indicate, this seems to be the canonical use-case for the block chain...
