The yen was up across the board during forex trading this morning (August 11th) and was making particularly strong ground against its higher-yielding counterparts.Hideki Hayashi, a global economist at Mizuho Securities, told Reuters that currencies such as the Aussie and the New Zealand dollar had suffered in a round of profit taking this morning.A recalibration in attitudes was in part sparked by new industrial output figures from China which, despite showing the fastest growth in nine months, had fallen short of some projections."Since the currency market overall has been on a correction phase, it looked at the more negative parts of the data as it needed trigger," said Mr Hayashi.This morning, Japan's central bank expressed its moderate optimism in the prospects for swift economic recovery as it voted to keep interest rates on hold at 0.1 per cent.The unanimous decision came after a two-day meeting held by the Bank of Japan to discuss the strength of the domestic, regional and global economy.
