Ribbit in Corporations
Being that the Issur Ribbit is only applicable Bein Yehudi l’Yehudi, dealing with large banks or public corporations is usually not a Ribbit problem. However, if a Jew is guaranteeing the loan, in many instances Halachah views his obligation as if the guarantor himself is the lender and would therefore be prohibited.
There are a surprising number of Halachot that depend on a company’s status. One example is Hametz. Only Hametz owned by a Jew becomes Hametz She’Avar Alav HaPessah. If a company with Jewish shareholders is considered Jewish, any Hametz that it owns over Pessah is forbidden to eat. Ribbit is another common example. If a bank is considered “Jewish”, every deposit or mortgage with the bank would have a Ribbit issue.
Another concern is how shareholders are affected. May one purchase shares in a food chain store knowing that it will own Hametz on Pessah? For that matter, many companies run cafeterias that serve Hametz. Is it permitted to own their shares? May one be a shareholder of a corporation that operates on Shabbat?
Logically, a company that has Jewish partners should be considered at least partially Jewish. Virtually every public bank has some Jewish shareholders, and yet it is customary to use credit cards, take out mortgages and make deposits with these banks. How do we justify this practice?
This is not a new issue. There are responsa dating back to the mid 1800’s in which the Poskim discuss whether banks may be used. The Kitzur Shulhan Aruch (65:28) forbids Jews from either investing with or borrowing money from “shpar kessa”, a primitive form of banks. Given that there may be Jewish investors, a portion of the money that one borrows from such an institution is considered a loan between two Jews. Investing money in these banks is also prohibited since a Jewish client may borrow that money.
The Sho’el U’Meshiv (Vol. 1, 3:31) argued that these banks may be used. He wrote to Rav Gantzfried requesting that he change his ruling in future printings of his Kitzur. Apparently, Rav Gantzfried declined to do so.
It is beyond the scope of this introduction to present a detailed analysis of all the responsa that discuss this issue. In practice, contemporary Poskim permit borrowing from banks when the majority of stockholders are non-Jews, unless the Jewish stockholders have a controlling share.
