Japanese consumer stocks tumbled on Wednesday as the yen flirted with a 40-year low against the US dollar, intensifying concerns over surging import costs for resource-dependent companies. The Nikkei 225 fell 1.8 per cent, with the Topix Consumer Goods Index dropping 2.4 per cent, as investors dumped shares in retailers, food producers and other domestic-facing firms.
The yen weakened to around 161 per dollar in early Asian trading, approaching the 1985 low of 162. Analysts pointed to the widening interest rate differential between Japan and the US, with the Bank of Japan maintaining ultra-loose monetary policy while the Federal Reserve keeps rates elevated. 'The yen's slide is a double-edged sword for Japan,' said Hiroshi Tanaka, senior market analyst at Tokyo-based Mizuho Securities. 'While exporters benefit from cheaper exports, domestic companies face a sharp rise in input costs, particularly for energy and food imports.'
Major decliners included supermarket chain Aeon, which fell 3.1 per cent, and beverage maker Kirin Holdings, down 2.8 per cent. Uniqlo-owner Fast Retailing dropped 2.2 per cent, dragging on the broader index. The sell-off was broad-based, with 187 of the Nikkei 225's 225 components closing in negative territory.
For UK investors, the yen's weakness has direct implications. Many British pension funds and retail investors hold Japanese equities through exchange-traded funds or actively managed global portfolios. The FTSE 100, which closed flat on Tuesday, showed little direct correlation, but analysts at Barclays noted that a sustained yen decline could weigh on UK-listed companies with significant Japanese exposure, such as insurers and asset managers. 'Currency risk is often underestimated in diversified portfolios,' said Sarah Jennings, investment director at AJ Bell. 'A weaker yen erodes the sterling value of Japanese holdings, even if share prices hold up.'
The Bank of Japan faces growing pressure to act, but Governor Kazuo Ueda has signalled no immediate policy shift, arguing that underlying inflation remains below target. Markets now expect the yen to test the 162 mark in the coming weeks, a level that would trigger fresh intervention concerns. 'The BOJ is in a difficult position,' Tanaka added. 'Raising rates could hurt the fragile economic recovery, but doing nothing risks further currency depreciation and higher import inflation.'
