The Ministry of Finance intervened in the market from late July through late August to steer the yen higher, deploying a monthly record ¥15.4 trillion ($96 billion).
Tokyo's Ministry of Finance announced that it intervened in the yen market from 30 July to 26 August to curb sharp fluctuations in the exchange rate. The intervention amounted to ¥15.4 trillion ($96 billion), the largest monthly total on record.
On 31 July, Tokyo and Washington carried out their first joint intervention in 28 years, seeking to curb the yen's decline amid the Japan-US interest rate differential and surging crude oil prices.
After reaching the previous month's high of ¥163.99 per dollar, the yen surged to ¥157.40 on 31 July and is now trading around ¥159.6. Fiscal spending plans, supply concerns and the situation in the Gulf are also said to have been factors.
