What is the ruling on publishing information about bonds and companies that deal with usury or are involved in prohibited activities (such as liquor companies and usurious banks), in the context of working to cover global financial markets?

The means take the rulings of the ends. So, whatever leads to the unlawful is unlawful. Publishing news about government bonds (usurious loans) and news about shares of prohibited companies is intended to facilitate and assist those who wish to purchase, and this falls under aiding in sin. Therefore, it is not permissible to remain in a job that aids in what is unlawful. And what wavers in the heart and to which the heart is not at ease is sin.
