While most laws stem from the Sages' logic presented in the Gemmorah, there is a subset of Halochos called Hukim (decrees) that are to be taken without understanding their reasoning.
Are there Hukim in monetary laws, between a Jew and his fellow?

Compiling some answers from the comments to the OP (feel free to add more):
בעליו עמו is a rather perplexing halacha that most people struggle to make sense of. See the Ibn Ezra and Chizkuni on the psukim (shemos 22:13,14) who both explain it albeit not in line with what the actual halacha is according to the gemara; see the Ralbag there who says a svara that doesn't apply in all cases; see Rav Hirsch there who has a big arichus trying to explain it. Tosfos in Bava Meitzia says that there taka is no reason (96a s.v. ונשאל).
I hope this was helpful.
One of the concepts of torts in Jewish law is גרמא בניזקין, which refers to an action that indirectly causes damage.
According to Jewish law, גרמא בנזקין פטור (Bava Kamma 60a), the tortious person is not liable for such damages, and the Beis Din will not charge him for them.
Nevertheless, the Talmud (Bava Basra 22b) teaches that גרמא בניזקין אסור, a person is prohibited from causing such types of damage, and while Beis Din doesn't obligate for such damages, the Heavenly court will punish the person, פטור מדיני אדם וחייב בדיני שמים.
תניא, אמר ר' יהושע, ארבעה דברים העושה אותן פטור מדיני אדם וחייב בדיני שמים, ואלו הן: הפורץ גדר בפני בהמת חבירו, והכופף קמתו של חבירו בפני הדליקה, והשוכר עדי שקר להעיד, והיודע עדות לחבירו ואינו מעיד לו
It follows that it's incumbent upon the person to oblige the laws of heaven, and to pay the damage, and until he does so, the sin will not be forgiven.
This is seemingly a paradox. If he's guilty in Heaven, then why doesn't Beis Din enforce payment?
For further discussion of this issue, see here: קימ"ל שגרמא פטור האם יש סברה לזה ?
Bava Kama 45b: R. Yehuda is of the opinion that a שור מועד, an ox that is identified as being likely to gore someone/something, needs less guarding than a שור תם, a regular ox.
I remember learning in Rambam,in certain cases,if someone was mentally ill or a minor and caused certain financial damages, you couldn't sue them for it and you had to swallow the loss. Remember the Rambam saying in the next paragraph, how it was best to stay away from such people if there is a chance that they could cause that certain type of financial loss.
