Dollar Nears 160 Yen as Tokyo Renews Warning Over Intervention Risks
Key Facts
Tokyo renewed its warning over the yen’s weakness as the dollar neared 160 yen, after Japan’s top currency diplomat, Atsushi Mimura, said on November 12 that recent currency moves were excessively rapid. Mimura added that markets had not yet forgotten the summer intervention, saying it was “still too early to forget” those operations. His comments came as the dollar rose to 159.94 yen on the same morning, its strongest level in more than two months. Trading data showed the dollar closed at 159.874 yen on November 12, compared with a close of 158.469 yen on November 6. The move leaves the yen near a threshold watched by markets, while officials’ remarks serve as a reminder that Japan has previously intervened to support its currency.
Chief Cabinet Secretary Minoru Kihara said Tokyo would continue close communication with the U.S. Treasury to maintain orderly foreign exchange markets. He said coordination would be handled through the Ministry of Finance, without announcing a specific action or timing for intervention. Kihara described the undervalued yen as a problem, signaling authorities’ concern over the currency’s continued weakness. The message comes as the dollar’s rise increases the cost of imports denominated in yen. Kihara did not link his remarks to an imminent decision, but stressed the goal of maintaining orderly foreign exchange markets.
The dollar rose in the Asian session on November 12 after strong U.S. inflation data and hawkish remarks from officials, factors that strengthened expectations of a U.S. rate hike. The dollar touched 159.94 yen, its highest level in more than two months, according to Reuters. Compared with the November 6 close of 158.469 yen, the move reflects the dollar’s widening gains in recent days. The pair then closed at 159.874 yen on November 12, according to market data. The trajectory shows that Japan’s warning came amid a documented rise in the dollar, rather than after a price move detached from U.S. policy expectations.
Intervention concerns stem from operations Japan carried out over the summer, when it intervened on three days between July 30 and August 3. Authorities spent a record 15.4 trillion yen during July, according to Reuters. Those operations came when the yen was nearing its weakest level in 40 years, at about 164 yen to the dollar. That history provides context for Mimura’s warning that it is still too early to forget the summer intervention. It also highlights the gap between November’s 159.94 yen level and the level at which the summer interventions took place, without implying that reaching any particular figure guarantees action by the authorities.
The effects of a weak currency extend beyond the foreign exchange market to the cost of imports and domestic spending. The yen-denominated import price index jumped 24.8% in October from a year earlier, according to data cited by Reuters. In September, average monthly spending by households of two or more people was 289,536 yen. Real spending fell 6.8% year on year, while nominal spending declined 4.5%, according to Japan’s Statistics Bureau. An official at the Ministry of Internal Affairs said poor weather limited people’s outings during the month, and Tokyo recorded rain every day in September for the first time in its history. The real decline was deeper than market expectations, while the figures put weak domestic demand alongside rising import costs.
Markets are watching Japan’s preliminary gross domestic product estimate for July to September, scheduled for release on November 16 according to the Cabinet Office calendar. The reading will provide a fresh indicator of growth and domestic demand after household spending fell in September, and will follow the dollar’s advance and renewed warnings over the yen. In an assessment published by Mizuho Securities, a break above 160 yen by the dollar could prompt Tokyo to intervene unilaterally if yen weakness fuels inflation and erodes support for Prime Minister Sanae Takaichi’s government. The firm also linked that possibility to a decline in political support for the government, and did not present it as an announced decision by the authorities. The 160 level therefore remains part of Mizuho’s assessment, while the November 16 GDP release remains the next scheduled economic milestone.
