The mechanics are simple. The Bank of Japan held rates near zero for a generation. Investors borrowed yen for almost nothing and parked it in higher-yielding assets abroad. The gap did the work. It is the largest, quietest leverage trade in finance, and no one can size it fully. It hides in bank books, pension portfolios and hedge-fund positions.
What we can see is the anchor. Japanese investors hold $1.24 trillion of US Treasuries - the single largest foreign holding, ahead of the UK's $897 billion (US Treasury data, February 2026). When Japan's own bonds start to pay, that anchor starts to drag.
How the yen carry trade works
¥
Borrow yen at near zero
Low rates from the Bank of Japan
Convert to USD (or other FX)
Sell yen, buy dollars
Invest in higher yielding assets
US Treasuries, global equities, EM debt, etc.
Earn the yield spread (“carry” )
Keep the difference as profit

Japanese yeilds are finally rising
On 16 June 2026 the BoJ raised its policy rate to 1.00%, the highest since 1995.
The trigger was the Iran energy shock feeding into inflation.
The 10-year JGB near 2.90% is a level unseen in nearly three decades. For the first time in a generation, a Japanese institution can earn a real yield at home.
The yen keeps falling anyway
Yields are up, yet the yen sits near a 40-year low around 162.
The driver is fiscal, not monetary: the Takaichi government's large spending and debt-issuance plans have markets selling JGBs on supply fears, not buying yen on rate hopes.
A bond market and a currency falling together is the classic signature of fiscal dominance - when investors doubt the balance sheet, not just the interest rate.
Japan has started selling US Treasuries
Japanese investors sold a net $29.6 billion of US bonds in the first quarter of 2026.
It is the largest quarterly reduction in nearly four years.
Higher hedging costs and more attractive JGBs make the maths obvious: bring the money home.

India is not at the center of this.However, it is not insulated either.
Flows
A carry unwind is a global risk-off event, and foreigners sell their most liquid emerging-market positions first, India's large caps included. Steady domestic SIP flows remain the cushion, as in every recent shock.
₹
The rupee
Already soft near ₹94 to the dollar, it would face renewed pressure in a dollar-up, risk-off move.
Rates
If US yields rise on Japanese selling, the RBI's room to cut ratesnarrows, and Indian equity multiples whicharestill a tadpremium to their own history, lose support.
Investor Insight — The one relief is relative. India's foreign ownership is lower than in 2021, and it carries less direct yen-funded leverage than higher-beta Asian markets. In an orderly move, India can outperform. In a disorderly one, correlation goes to one, and nothing is spared

Ametra’s Read
The unwind of the yen carry trade is ultimately a liquidity story, not just a currency story. As Japan's capital gradually returns home, higher global volatility and rising discount rates become key portfolio risks. We continue to favour quality over duration, maintain gold as portfolio insurance, stay selective in richly valued global equities, and use any India correction driven by global liquidity—not fundamentals—to add high-quality businesses.
