Dear Sir/Madam:

Pursuant to Rule 477 of the Securities Act of 1933, as amended (the “1933 Act”), SPDR Series Trust (the “Trust”), on behalf of its series SPDR NYSE Dynamic SPY Buy Write ETF (the “Fund”), hereby respectfully requests withdrawal of Post-Effective Amendment No. 198 (“PEA No. 198”), which was filed with the Securities and Exchange Commission (the “Commission”) via EDGAR (Accession No. 0001193125-16-764496) on November 9, 2016, pursuant to paragraph (a)(2) of Rule 485 under the 1933 Act. PEA No. 198 is scheduled to become effective on January 23, 2017.
