On 3 May 2017, a resolution authorized the Banco Central del Uruguay to introduce up to 10 million new 50-peso uruguayo polymer notes to commemorate the 50th anniversary of the bank. When these notes were introduced on 14 September 2018, the bank indicated that it intends to use polymer substrate for other lower denominations in the future, with the physical size of the notes increasing according to their denominations.
