The yen hit a two-and-a-half year high against the dollar on Tuesday as Toshihiko Fukui, governor of the Bank of Japan, expressed strong concern about the turbulence in world markets, comparing it with “a serious disease”.

The yen briefly rose to Y107.17 against the dollar, although it fell back to Y108 in Tokyo trading. Before July, when investors began to reverse some so-called yen carry-trade positions amid a retreat from risk, the currency had been trading at above Y120 to the dollar.

sharp oscillations sent Japanese equity markets gyrating, with the Nikkei index falling 300 points in the morning amid concern about the effects of a strong currency on exporters, before it rallied to close up 87.64 points as the yen drifted down again. Mr Fukui said the volatile movements in financial markets since July suggested global markets were paying the price for “euphoria and excessive risk-taking”. It was the central bank’s job, he said, “to help markets adjust themselves in an orderly manner as far as possible, while keeping markets functioning at all times.”

The BoJ has reacted to the US mortgage crisis by putting an expected interest rate rise on hold, keeping overnight rates at 0.5 per cent. Although the bank has fractionally pared back its growth and inflation predictions for this year, it has stuck to its central thesis that Japan’s economy remains in a virtuous cycle.

Masaaki Kanno, chief economist at JPMorgan in Tokyo, said a strengthening yen clouded the picture. If the yen broke through Y100 or Y90 to the dollar, he said, it could “be a big blow to the economy” and once more raise the spectre of deflation.

“In the past we didn’t worry so much about yen strength as we believed the global economy would grow steadily,” he said. “But if the strong yen is caused by the slowing of the global eco- nomy together with the spread of risk aversion, then probably we should be a bit more worried than before.”

Other economists said concern about the yen comes on top of worries about the domestic economy, partly brought on by a sharp fall in housing starts.

Jonathan Allum, strategist at KBC Financial Products, said the yen was still relatively weak against the euro, a fact that had helped underpin strong exports to European countries.

On Tuesday, the yen, which peaked at Y168 to the euro in early July, had strengthened to about Y160, compared with previous levels of about Y130.

If the yen appreciated further against the euro it could damage exports to Europe, Mr Allum said. But the “knee-jerk reaction that a strong yen is bad and a weak yen is good [for Japan] is probably a bit out of date.”

Japanese politicians have said that a strong yen is not bad for Japan in the long run, but they have warned about the dangers of sharp movements.
