Wall Street banks Citigroup, Morgan Stanley and Goldman Sachs will next week kick off the 2015 bonus season in earnest – a period that typically precedes a months-long round of hiring among the world's largest investment banks.

Citigroup and Morgan Stanley will announce bonuses to staff next Friday, January 16, while Goldman Sachs will begin the process of communicating payouts to its partners on the same day, according to people familiar with the banks' plans.
