Japan abandoned its decade-long reflation doctrine this week. The government pledged fiscal discipline after currency depreciation pushed the yen to 164 against the US dollar.

Prime Minister Sanae Takaichi told parliament that 2026 begins a period of responsible fiscal management. The statement formally disavowed the easy-money playbook championed by former leader Shinzo Abe.

During parliamentary debates on Oct 8, Takaichi rejected the reflationary tag and laid out plans to steer domestic capital into higher-productivity sectors. That pivot followed a tense Sept 22 meeting in New York with US President Donald Trump. Trump complained that a cheap yen penalises American exporters. US Treasury Secretary Scott Bessent increased pressure shortly after, explicitly telling Tokyo to halt its reflation policies.

Tokyo spent more than 27 trillion yen on direct foreign exchange interventions in 2026 alone to defend the currency. In July, Japanese and American authorities conducted a joint yen-buying operation, their first coordinated market intervention since the 1998 Asian financial crisis. The gains faded quickly. The interest rate gap between Tokyo and global central banks remained wide.

For retailers and consumer goods distributors across Japan, prolonged currency weakness has inflated wholesale import costs for food, energy and raw inputs. Core consumer inflation in Tokyo reached 2.7 percent year on year in September. That eroded household discretionary spending despite nominal wage growth. Retail margins on imported apparel, processed foods and electronics have tightened, forcing store chains to lift shelf prices.

Regional supply chains and consumer brands face higher borrowing costs as the Bank of Japan normalises monetary policy.
