Strategists trying to figure out Japan’s next move on the yen are looking to the International Monetary Fund’s technical guidelines for clues. Tokyo’s intervention on Thursday sent the yen surging more than 3% against the dollar, marking its latest attempt since around April‑May to haul the currency back from a 40‑year low.
