Bank of Japan Ends the Era of Ultra-Loose Policy: What It Means for Global Bond Markets
- ▸The Bank of Japan raised its policy rate from -0.1% to positive territory in early 2024 and has continued gradual normalisation — ending a negative rate policy that lasted nearly a decade.
- ▸The BOJ's yield curve control programme, which capped 10-year Japanese government bond yields, has been phased out, allowing Japanese yields to rise and the yen to recover from historic lows.
- ▸The estimated $4 trillion yen carry trade — borrowing cheaply in yen to invest in higher-yielding global assets — is gradually unwinding, with significant implications for global bond and equity markets.
For nearly three decades, the Bank of Japan operated as the world's most unusual central bank — holding interest rates at or below zero while buying government bonds on an almost unlimited scale. In early 2024, it began to change course, raising rates for the first time since 2007. By mid-2026, the BOJ's policy rate sits at 0.75%, with further gradual increases signalled.
What Was Yield Curve Control?
Yield Curve Control (YCC) was the BOJ's policy of capping the 10-year Japanese Government Bond (JGB) yield at 0%, then 0.5%, then 1.0% — essentially promising to buy unlimited quantities of bonds to prevent yields from rising. This kept borrowing costs low across the economy and was intended to stimulate inflation after decades of deflation. It succeeded, eventually — Japanese inflation rose above 2% in 2023 for the first time in decades. That success triggered the need to exit.
Why Does This Matter Globally?
Japan is the world's largest creditor nation. Japanese investors hold trillions of dollars in foreign assets — US Treasuries, European sovereign bonds, Australian bonds, and equities. As Japanese interest rates rise and the yen strengthens, some of those offshore investments become less attractive relative to domestic alternatives. The repatriation of capital — even partial — moves global bond and currency markets.
The unwinding of yen carry trades — where investors borrow cheaply in Japan to invest in higher-yielding assets — has periodically triggered capital outflows from Indian equity and bond markets. When the BOJ hikes rates unexpectedly, yen appreciation forces carry traders to sell EM assets to repay yen-denominated loans. India, with significant FPI presence in its equity market, has seen sharp single-day outflows correlated with BOJ policy surprises. The RBI has managed these episodes by deploying forex reserves as a buffer, but sustained BOJ normalisation requires ongoing vigilance in India's capital account management.
