Japan's core inflation surpassed the Bank of Japan's two percent target, immediately repricing rate expectations and compressing the JGB yield curve. The two-year JGB yield jumped six basis points while the 10-year rose four basis points, narrowing the slope as short-end rates priced in imminent policy tightening.
Futures markets now assign an 80 percent probability to the BOJ ending its negative interest rate policy at the December 19-20 meeting. Such a move would mark Japan's first rate hike in 17 years and represent a formal exit from yield curve control—the ultra-loose framework that has anchored JGB yields for years.
The yen strengthened against the U.S. dollar as investors repriced the interest rate differential between the two economies. This deleveraging of carry trades—which have profited from borrowing low-yielding yen to fund higher-yielding assets—sent a ripple through global duration markets. U.S. Treasury yields moved three basis points higher in sympathy, signaling that portfolio managers are already adjusting duration risk across developed bond markets.
BOJ Governor Kazuo Ueda has said sustainable wage growth is necessary to justify the two percent target. This inflation reading suggests that threshold may be within reach, giving the central bank political cover for normalization. Bond traders are now parsing every BOJ communication for hints about the pace and scope of rate increases and the future of yield curve control.
