The Japanese yen jumped sharply against the US dollar on Friday, following reports that Tokyo authorities intervened to prop up the currency. This sudden rally occurred a day after official buying was widely believed to have lifted the fragile currency.
Prior to the move, Finance Minister Satsuki Katayama issued an unusual warning for traders preparing for national holidays. While the government and central bank typically do not announce when they intervene in currency markets, traders and analysts stated the move had all the hallmarks of an intervention. Japan's top currency official later declined to comment on the reports.
Analysts warn that the current rally is at risk of evaporating quickly, as the factors contributing to a weaker yen remain unchanged. Consequently, Japan's top foreign exchange diplomat stated that Tokyo is ready to step back into the markets. With the likelihood of further action increasing, traders are bracing for another round of intervention to shore up the exchange rate.
