LONDON, Feb 21 (Reuters) - Japan's yen bounced sharply in early European trading on Friday, as traders swooped back into the currency after its worst four-day run in over two years.
The Japanese currency had lost 2% against the dollar in the previous two days alone as worries about the impact of the coronavirus on Asia had spread, but its early burst in London left it up 0.5% on the day at 111.5 yen. JPY= the support for the yen comes from two sources, general risk-off sentiment and a move to safe-haven bonds," said Saxo Bank's head of FX strategy John Hardy.
The week's dramatic slide, though, has raised more fundamental questions about the yen's reputation as a safe harbour when FX markets get stormy.

"New cases in (South) Korea and in Japan, (have) obviously given some people a little bit of cold feet regarding Japan and the yen as a safe haven," said David Bloom, global head of FX at HSBC.
"They're thinking: 'Maybe Swissy and gold are better'. So there is a little bit of scratching of heads, there's no doubt about it," he said, adding he was not yet prepared to abandon the idea of the yen as a safety play.
The day's other focus for Europe was a blizzard of purchasing managing index data which due to their forward looking nature are seen as one of the better indications of current economic conditions.
