REUTERS/Florence LoSINGAPORE, Oct 24 (Reuters) - The Japanese yen made a thumping 4 yen jump for a second straight session on Monday on suspected early intervention by the Bank of Japan, but struggled to hold its gains against a robust U.S. dollar.
"It's blindingly obvious that the BOJ is intervening," said Ray Attrill, head of FX strategy at National Australia Bank in Sydney.
"While sub-optimal and unsustainable in the medium term, we think this policy mix could be in place for some time."
The Australian dollar was down 0.4% versus the greenback at $0.6370, while the kiwi was up 0.16% on its U.S. peer at $0.576.
