The term 'SMALLEST POSTAGE HIKE' is composed of four words, with the first word being 'CENT', which is a 4-letter word. The United States Postal Service (USPS) has recently announced a postage hike, which is the smallest increase in the past decade. This increase will take effect on January 26th, 2020 and will raise the cost of a First-Class stamp from 55 cents to 58 cents. The USPS has stated that this increase is necessary to help cover the costs of providing services to customers.
