On the first one, the kerning between "n" and "c" could be hair tighter.

What is the significance of the \?

Is it all lowercase because this type doesn't have uppercase? I think it could benefit from capital letters.

The typeface is made by me and doesn't have uppercase yet, but even if it had I wouldn't have used them. I fined that capitals tend to stand out to much and take away the unity in shape. The backslash is simply to create a strong and recognizable image.

If that were true, then the majority of logos out there don't have a "unified shape."

Does it pertain to anything in the logo or with the company? It seems kind of disconnected from the logotype, and the company as a whole. I think something more thought out should go in there instead of something just stuck there "to create a strong and recognizable image."

*update: I uploaded a third option.

To me, the breaks in the letters and the mixed case are too unstable for a financial company. What are their purpose?

"What are their purpose?" This wasy they can be used as a stencil so their brand name can be cut out on their business card.

I feel like all of these decisions have no rhyme or reason...

Why would a financial company need a stencil? If that ends up being its brand, that's fine, but the type in the last one is pretty unsettling. U&lc R's in one word, a lowercase f and capital C that have stencil holes for no reason, etc., and the counter of the capital R doesn't have a stencil hole. So far, your second version is the best choice.
