The Bank of Japan will refrain from draining funds that entered the market through the government's yen-selling intervention last week, a BOJ source said on Monday.

Japan's intervention likely totalled a record amount around 4.5 trillion yen ($57 billion), BOJ data suggested last week. ($1 = 78.490 Japanese Yen) (Reporting by Rie Ishiguro; Editing by Joseph Radford)
