Yen sinks to 40-year low as Japan firms warn

The Japanese yen fell to its weakest level in 40 years on Aug 10, 2026, market data showed, prompting warnings from senior executives at major Japanese companies about growing pressure on profits. The offshore foreign-exchange market reaction was still pending at the time of the report.

Corporate leaders said the currency’s decline was already squeezing exporters’ margins, even as a weaker yen can lift the value of overseas sales when earnings are brought home in yen terms. They also flagged uncertainty around near-term price setting and contract terms as firms adjust to a fast-moving exchange rate.

Executives in Tokyo cite cost shocks and planning strain Executives said the weaker yen was pushing up import costs for manufacturers and retailers, particularly where inputs are linked to the U.S. dollar. They said this dynamic complicates budgeting and can force companies to revisit assumptions used for procurement and inventory planning.

Exporters may report higher repatriated revenue in yen terms, but they said any benefit can be offset when production relies on imported energy, components, or other foreign-currency-priced inputs.

Non-exporters and households, executives said, would be more directly exposed to higher costs for fuel and components. They warned that sustained currency weakness would raise operating expenses and could tighten profit margins across sectors that depend heavily on imports.

Officials monitor the move as traders focus on Aug 11 Officials said they were monitoring the yen’s decline. The report did not include any central bank intervention or a policy announcement related to the currency’s move.

Markets are expected to watch Tokyo trading on Aug 11, 2026, for signs of follow-through in the yen and for any statements from companies or officials that could influence dealer positioning. Executives said that if weakness persists, companies may face pressure to revise 2026 profit guidance, though the scale and timing of any changes remained unclear.
