TOKYO, April 11 (Reuters) - Japan would not be able to change the fundamental trend of the currency's value even if it intervened to stem yen rises, the head of the Organisation for Economic Co-operation and Development said on Monday.

OECD Secretary-General Angel Gurria, speaking at a press conference, said the fact that the yen is seen as a safe-haven currency is not something that intervention can change.

The dollar hit a fresh 17-month low versus the yen on Monday despite Japanese officials' ratcheting up warnings that Tokyo will take appropriate steps as needed to curb disorderly moves in the currency.
