為替介入、５兆円規模か　２９日実施の可能性

　政府・日銀が２９日の外国為替市場で、円買い・ドル売りの為替介入を実施していた可能性が高いことが３０日、分かった。日銀当座預金の増減要因予想に基づく市場関係者の推計によると、介入は５兆円規模。日本が祝日だった２９日の海外市場では円相場が一時、１ドル＝１６０円台まで急落。その後、一転して数時間で１５４円台まで円が買い戻される場面があり、市場では複数回にわたって介入が実施されたとの見方が広がっていた。

Japanese authorities are believed to have conducted yen-buying, dollar-selling foreign exchange market intervention worth some 5 trillion yen Monday, it was learned Tuesday.
   The estimate was given by market players based on Bank of Japan data on projected changes in commercial financial institutions' current account balances at the bank.
   On Monday, the dollar slumped below 155 yen just hours after exceeding 160 yen for the first time in about 34 years. This happened in overseas trading because the Tokyo market was closed for a national holiday.
   The abrupt moves fueled speculation that the Japanese authorities stepped in to buy yen and sell dollars on multiple occasions. The government has declined to say whether any such intervention was conducted.
   Current account balances at the BOJ change in line with the movements of funds deposited by private financial institutions with the central bank. On Tuesday night, the BOJ released projections of changes in the current account balances for Wednesday.
