Japan's Interest Rate Hike Signal Triggers "Bloodletting" Worries in U.S. Markets, Fed's Rate Cut Prospect May Change

December 2 Japan, the largest foreign holder of U.S. Treasury bonds, could trigger a repatriation of domestic funds from U.S. bonds and other overseas assets if it tightens monetary policy—disrupting the U.S. Treasury yield’s downward trend and sowing global market uncertainty. On Monday, global government bond yields broadly climbed after Bank of Japan (BOJ) Governor Haruhiko Kuroda signaled a possible interest rate hike later this month. (Bond yields rise as prices fall.) The comment caught investors off guard—markets had expected the BOJ to keep policy unchanged. Kuroda’s remarks pushed Japan’s 10-year government bond yield to 1.879%—its highest closing level since June 2008. U.S. 10-year Treasury yields also climbed to 4.095%—up from just below 4% mid-last week. Wall Street is worried rising Japanese bond yields will draw capital away from U.S. assets, pushing U.S. Treasury yields higher. Japan holds roughly $1.2 trillion in Treasuries as of September, making it the top foreign holder of U.S. government debt. This year, falling U.S. Treasury yields have helped drive the Federal Reserve’s repeated rate cuts—cuts that have lowered mortgage rates and lifted stocks. Stocks typically benefit from lower yields because investors can no longer get the same risk-free returns by holding bonds to maturity. Japan’s monetary tightening signal has also stoked fears about the Fed’s rate-cut outlook—rising U.S. yields would hinder further rate cuts.
