Yen Surge Weighs on Japanese Stocks; Strategists Say Earnings Downgrade Risk Is Limited
Miles Bennett
A sharp yen rally on Monday sent the Topix down 1.1%, but strategists say the currency still sits roughly ¥5 above the threshold embedded in corporate earnings forecasts — limiting real damage to exporters.
How thick is the earnings "cushion"?
A Bank of Japan survey of over 800 firms puts the weighted-average assumed exchange rate at ¥151.49 per dollar.
At the time of writing the yen traded around ¥156.96, still about ¥5 from that trigger level.
This means → the yen is strengthening, but it has not yet reached the pain point that would force broad earnings downgrades.
What are strategists saying about this sell-off?
Yugo Tsuboi, chief strategist at Daiwa Securities, argues earnings-downgrade risk stays low unless the yen pushes to around ¥150.
He adds that at current levels the appreciation does not fundamentally hurt corporate profits.
Naoki Fujiwara, senior fund manager at Shinkin Asset Management, notes the earlier rally was not purely yen-driven; automakers may see a sentiment "reset" when they report earnings.
Why did the yen spike so sharply?
The move was triggered by coordinated U.S.-Japan intervention — officials talked the yen up to ¥157.57 on Friday.
On Monday morning it briefly touched ¥155.23, the strongest since early May.
In plain terms = this was not the market betting on yen strength by itself; two governments hit the brakes together.
Has the yen-equity link broken down?
The correlation between the two has weakened noticeably in recent months as investors shifted focus to the AI theme.
A clear divergence appeared in July: the yen fell to a nearly 40-year low, yet Japanese stocks still dropped, dragged by an AI-sector sell-off.
This reflects a growing view that the earnings boost from a weak yen cannot offset the negatives — higher imported inflation and deterred foreign buying.
What should investors watch next?
Nomura strategist Maki Sawada expects exporter earnings to improve year-on-year as yen-weakness benefits persist and U.S. tariff effects fade.
Stocks sold off on yen-appreciation fears could attract renewed buying once earnings are reported.
The near-term risk: coordinated intervention raises the chance of further sharp currency swings, keeping sentiment under pressure.
