Japanese Yen Vulnerable, USDJPY Nears 160 Amid Intervention Talks. The Japanese yen was weak on Monday, with the USDJPY pair approaching a key mediation level even as government authorities repeated alerts that they would intercede to help the cash. The pair, which estimates how much yen expected to get one dollar, rose somewhat to 159.93 yen on Monday. The pair almost arrived at 160 yen, the most elevated level in over 30 years, and had provoked government mediation in May.
