Foreign investors pour $18.65 billion into Japanese stocks on return after three weeks

• The Nikkei rallied 5.39% on Wednesday following the U.S.-Iran ceasefire agreement announced the day before
• Seasonal factors played a role as foreign institutions typically move holdings offshore in March before dividend entitlements are fixed, then return them in April
• Japanese investors made their largest foreign stock purchase in 11 months at 1.44 trillion yen, while foreign investors also put 2.46 trillion yen into Japanese government bonds amid yields hitting near three-decade highs

Summary: Foreign Investors Pour $18.65 Billion into Japanese Stocks

Key Development:

Foreign investors injected a net 2.96 trillion yen ($18.65 billion) into Japanese stocks during the week ending April 4, 2026, marking a dramatic reversal after three consecutive weeks of outflows. This inflow reversed nearly two-thirds of the previous week's 4.45 trillion yen in withdrawals.

Market Drivers:

• The Nikkei rallied 5.39% on Wednesday following a ceasefire agreement between the U.S. and Iran, stabilizing investor sentiment
• Seasonal factors played a significant role, as foreign institutions typically shift holdings offshore in March before dividend entitlements are fixed, then return them in April
• Rising Japanese government bond yields, reaching near three-decade highs, attracted additional foreign capital

Additional Capital Flows:

• Foreign investors poured 2.46 trillion yen into Japanese long-term bonds
• Japanese investors invested 1.44 trillion yen into foreign stocks—the largest amount in 11 months
• Japanese investors sold 2.46 trillion yen in foreign long-term bonds, marking the fourth consecutive week of net selling

Context:

Foreign investors had withdrawn nearly 7.37 trillion yen from Japanese stocks during March 2026, making this week's inflows particularly significant.

Market Implications:

The substantial capital return suggests renewed confidence in Japanese equities following geopolitical risk reduction and seasonal normalization. The concurrent strength in JGB yields indicates broader foreign interest in Japanese assets. Cross-border flows demonstrate continued portfolio rebalancing between Japanese and international investors, with Japanese institutions favoring foreign equities while divesting overseas bonds.
