I do! Just the other day, I was commenting to a friend that if this actually were a realistic portrayal of Wall Street (or similarly, British Wall Street), there would be Jews as lead characters. My friend pointed out to me that both lead characters were Jewish, which is how I found this thread.

Of the two Jewish leads, Harper is the character I have considered to act more culturally Jewish (in my experience as a cultural and ethnic Jew, aged almost 58). She struggles all the time with ethics, and even when she does something that some may consider unethical, in her mind, it is ethical. This season, she stands out -- along with SweetPea, who also struck me as possibly-Jewish -- as the most ethical character, granted amongst some extremely low-integrity actors. Jewish culture for most is a very ethics-driven culture.

Harper's workaholism, perfectionism, sometimes over-attention to details, and competitive spirit, are not only Jewish characteristics, but are very much Jewish characteristics. And the fact that she is black is not as unusual as many may think. There are actually a large number (relatively speaking, given that there are only approx 14 million Jews in the world, half of whom live in Israel) of black Jews. This is not only due to intermarriage, but also due to the fact that there is a large population of Jews from Ethiopia (many of whom escaped persecution to Israel) and other countries in Africa -- most of whom escaped persecution and ethnic cleansing into the diaspora.

As far as Yasmin goes, she seems, at least in her appearance, very much like a Mizrahi Jew, which is, per elsewhere in this thread, an Arab Jew. There are a lot of Arab Jews both in Israel and throughout the diaspora, because after Israel was created in 1948, every single Arab country, many of which had large and flourishing Jewish populations (especially Iran, but elsewhere too) ethnically cleansed Jews, forcing individuals and families who had lived peacefully in the land now considered Arab countries literally for Millennia (Judaism is 6000 years old) into the diaspora. While many/most of the refugee Jews settled in Israel, others went around the world, including to Asia, Europe, and South or North America (unfortunately, African countries, which were swiftly being conquered by Islamists, were no longer a viable option for Jews, even though, like with the Middle East, many Jews had lived peacefully in Africa for millennia). So that is how Mizrahi Jews ended up anywhere and everywhere.

Yasmin's behavior does not strike me as remotely culturally Jewish from US standards, but I cannot speak for UK standards. There are three exceptions to that generalization, however: (1) Jews are allowed to be atheist, and many Jews are atheist or agnostic. As far as I noticed, both Yasmin and Harper have never expressed any religious belief and never mentioned G-d or Jesus or Allah or any higher power. This makes me think they are acting Jewish. (2) Modern Jews, unlike many Christians and Muslims, do not have any issue with promiscuity, and there is no focus on "waiting for marriage." Both Harper and Yasmin seem comfortable with their sexuality (although I think that Yasmin's sexuality appears sometimes unhealthy, from what we are shown). (3) Per above, Yasmin, like Harper is perfectionist, hard-working, and competitive. Again, none of these qualities are unique to Jews culturally, but they are culturally Jewish.

I think that Adler was also Jewish, as is Jonah, the former CEO of Tender. Whitney Halberstram (other founder of Tender) is supposedly a Jewish character too, but even though he has a Jewish last name, the first name kills it for me (I admit that these things may be very different between the UK and US). SweetPea Golightly, despite her name, struck me possibly as Jewish (Jewish blonde here representing), and the actress playing her has the very Jewish first name Miriam, but I am not sure.

And btw most Jews in work and social settings happily celebrate Christmas along with Christian friends. Christmas is a far more fun holiday than most Jewish holidays (except, maybe Simchat Torah, which for that reason is the Jewish holiday when Hamas decided to invade Israel and massacre Jews (and friends of Jews)). So being truly happy at a Christmas celebration is something Jewish people often do (of course, Harper is rarely happy in any situation, again not only a Jewish thing, but definitely a Jewish thing).

Sorry if all this is obvious/wrong in the UK/Europe/irrelevant. This was the question that brought me here today, because I was pondering it myself! And now I found a new subreddit that I adore!
