  • December 19, 2022

(Bloomberg) — The yen rallied while stocks and bonds slumped in the wake of the Bank of Japan’s unexpected adjustment to its yield-curve control policy.

A day that began with listless, mildly downbeat trading in Asia was thrown into turmoil when the BOJ increased the upper limit of its tolerance band on 10-year government bonds to 0.5% from 0.25%.

The Japanese currency, which had been appreciating since late October, surged almost 3% versus the dollar to the strongest level since mid-August. US and European equity futures slumped and Asian stocks extended declines, with a gauge of regional shares headed for a fourth straight decline.

Japan’s 10-year yield, which had moved at a glacial pace in recent years under the weight of the BOJ’s YCC regime, surged more than 20 basis points, to the highest since 2015.

Similar-maturity yields in Australia moved by around the same amount while the 10-year Treasury yield leaped 10 basis points for a second day.

“The Bank of Japan once again teach us that complacency is the devil,” Matthew Simpson, senior market analyst at City Index, wrote in a note. “This is arguably the biggest surprise they have handed markets since moving to negative interest rates in January 2016.”

The yield-curve control change may reflect Japan’s preference for a stronger yen, according to National Australia Bank. “A wider YCC band favors a stronger yen as long as 10-year Treasuries don’t sell by more than Japanese government bonds,” said Rodrigo Catril, the bank’s Sydney-based strategist.

A gauge of the dollar dropped as the yen rallied. Then yen also showed notable gains against currencies including the euro and the Australian dollar.

Equities were already on the back foot given broader investor concern on the global inflation outlook.

Underscoring the poor global sentiment, former New York Fed President and Bloomberg Opinion columnist William Dudley told Bloomberg Television on Monday that optimistic markets could only make the central bank tighten even more.
