अनुबाद - फ्रान्सेली-अंग्रेजी - Le monde de la finance, un monde qui fascine...

causes desire and fear --> causes desire, but it also causes fear
the money management --> money management
the failure --> failure

Well, here's my version, for what it's worth:
---
The world of finance, a world which fascinates certain people. For such people, the world of finance gives rise to desire, but it also gives rise to fear.
The first rule to be observed is that of assets management.
Insufficient assets management leads to certain ruin.

I will freely admit am out of my element in the field of economics. However, I do feel quite confident that it is
finance
and not
finances
?

Shouldn't it be "asset management", and not "assets management"? It sounds weird to me with the plural, but I'd be willing to go with it if that's a term that is used a lot in economics.

Yup, toldja I was out of my element!
I guess this site, for example, also has "money management," which I didn't think was an economics term!
So I guess
The first rule to be observed is that of assets management. Insufficient assets management leads to certain ruin.
is wrong, and
The first rule to be observed is that of money management. Insufficient money management leads to certain ruin.
is right!
Thanks, kafetzou!

Here's my translation:

The world of finance, a world which fascinates certain people. For such people, this world causes desire but fear too.
The first rule to be observed is that of money management.
Lack of money management means failure.
