Yen Carry Trade

Yen carry trade is the funding strategy discussed in EP38 风满楼！全球资本市场巨幅动荡，腥风血雨时刻近在咫尺 where investors borrow cheap yen and use the proceeds to buy higher-yielding or higher-return assets elsewhere. The episode treats this as a powerful but fragile structure because exchange-rate moves and funding-cost changes can overwhelm the original interest-rate spread.

Key Claims

• The trade is attractive when yen funding is cheap, the yen weakens or stays stable, and target assets rise.
• It becomes dangerous when the Bank of Japan tightens, the yen appreciates quickly, or target assets begin falling at the same time.
• Leverage turns a currency move into a solvency problem because small exchange-rate changes can erase the expected carry.
• The trade can connect Japan, U.S. equities, bonds, and global risk assets even when local fundamentals have not changed at the same speed.

Connections

• Carry Trade Unwind — forced or voluntary closing of the trade.
• Bank of Japan and Federal Reserve — policy spread behind the setup.
• Derivative Amplified Volatility — leveraged and derivative exposure can magnify unwinds.
• Investment Risk Management — leverage and currency exposure require humility and position sizing.
