円買い介入、５兆円規模　２１日、過去最大―政府・日銀

　市場筋によると、政府・日銀が２１日に外国為替市場で実施した円買い・ドル売り介入は５兆円規模に上ることが２４日、分かった。９月２２日に実施した２兆８３８２億円を超え、円買い介入として過去最大とみられる。今月２１日の海外市場では、１ドル＝１５２円に迫る急速な円安が進行していたことから政府・日銀が円買い介入に踏み切り、一時、一部の電子取引で１４４円台を付けたとみられるなど円相場が急騰した。（2022/10/24-20:22）

Japan's yen-buying, dollar-selling market intervention late last week is believed to have totaled some 5 trillion yen, market sources said Monday.
   It was apparently the largest such intervention ever by Japanese authorities, topping the 2,838.2-billion-yen intervention on September 22.
   The latest intervention came after the yen fell close to 152 per dollar in overseas trading on Friday, and is believed by some to have boosted the Japanese currency past 145 on electronic broking system.
   According to data released by the Bank of Japan on Monday, financial institutions' current account deposits at the BOJ are forecast to decrease by 1.18 trillion yen on Tuesday due to "fiscal policy" factors. There was a 5-trillion-yen gap between the projected decrease and the market consensus estimate for an increase.
   The deposits shrink after yen-buying interventions, as the Japanese government buys yen from financial institutions.
