Japan's Nikkei Stock Average experienced a notable rebound and climbed to its highest level in three months amid ongoing trade negotiations between Tokyo and Washington. The index rose by 457 points on April 17, supported by optimism surrounding the easing of U.S. tariff measures and strong earnings from semiconductor company TSMC. The market responded positively to the absence of currency discussions in the talks, which contributed to a temporary weakening of the yen, with the exchange rate fluctuating around the 141 to 142 yen per dollar range. Technology, internet, and heavy industry stocks led the gains, reflecting investor confidence in the potential for a favorable trade deal. The Tokyo Stock Exchange closed at 34,583 points on April 18, with the week marking the best performance for the Nikkei in three months. This upward trend was further bolstered by reduced concerns over U.S. tariff policies and a general buying preference among investors.
