NEW YORK, April 15 (Reuters) - Any adjustments the Federal Reserve makes to the allocation of its Treasury purchases would be technical in nature, meant to keep purchases neutral, and proportional to the broader market, a senior New York Fed official said on Thursday. “It’s important to keep in mind that these are minor technical adjustments,” said Lorie Logan, an executive vice president at the New York Fed and the manager of the System Open Market Account. The Fed will aim to implement these adjustments in the next schedule for monthly asset purchases, which will be released on May 13, she said. (Reporting by Jonnelle Marte Editing by Chris Reese)
