Hiring manager perspective: Nope. Glad you finished. If you're a new grad without much experience outside of internships (meaning you didn't work in the relevant field while obtaining your degree), I will care more about your GPA. As a general matter, I often don't even look at or ask about GPA because it matters very little to me, but if you took 6 years to get a bachelors I'd prefer to see good grades. After all, when everyone else crammed 15-18 credits per semester, it's fair to expect that the person doing 8-12 per semester for a longer period of time should have better grades. Of course, if there are external factors beyond wanting/needing more time to do the coursework, that's taken into consideration as well.
Be prepared to talk about why it took you longer. It's not a bad thing to be asked, in the same way that other hiring managers asking about my law degree/legal experience isn't bad either, it's just out of the norm for someone working in fintech. Be honest - you can say there were family reasons or whatever without getting into the details. If your interviewer is anything resembling a human, they'll understand. If they don't, you're avoiding a shitty work-life balance situation and/or a shitty boss.
If you don't have other experience, though, or don't need/want to illustrate that your degree happened while you were doing other relevant, career-path work, you could just put the graduation date on your resume.
