Five charts on the Japanese yen's decades-long drop

Japan's yen saw a sudden jump on Monday, suggesting the country's authorities may have finally followed through on the FX market intervention warnings they have be making for months. Monday's moves follow a near-11% drop in the yen's value against the dollar this year and a 35% slump over the last three decades that has pushed it to a 34-year low. Monday's suspected intervention came after the yen dived past 160 to the dollar, well below where most FX traders had thought it would get to before the Bank of Japan reacted.
