According to Bloomberg's calculations based on central bank reserve data and brokerage forecasts, the Japanese government likely expended approximately 4.68 trillion yen ($30 billion) to intervene in the foreign exchange market to bolster the yen.

The information does not allow for identifying the exact day since the end of last week when the authorities bought the national currency, nor if they intervened multiple times. Investors observe that the yen's sudden rise on Wednesday may suggest atypical movements in the currency market.

By the end of April, the authorities had intervened with approximately $34.5 billion, based on comparable information. Goldman Sachs analysts observe that officials have the ability to carry out around 30 additional interventions of similar magnitude, though these will probably be aimed for optimal impact.

In recent times, the Japanese government has continually implemented steps to bolster the national currency as it neared the psychological threshold of 160 yen for one dollar.

Vice Finance Minister Atsushi Mimura conveyed on Thursday that officials are ready to take decisive measures as speculative trading persists in the market.
