Ten-year Japanese Government Bond (JGB) yield soars to an over-16-year peak of 1.6%

In a significant development for the global economy, U.S. President Donald Trump announced a reciprocal tariff agreement with Japan on July 23, 2020. The agreement, which will see a 15% U.S. tariff on imports from Japan, has had a positive impact on Japan’s financial markets, including the Japanese government bond (JGB) market.

The tariff reduction, which will lower Japan’s country-specific reciprocal tariff rate from 25% to 15%, was welcomed by Japanese markets and seen as a trade win. This move is expected to reduce downside economic risks for Japan and lift market sentiment.

The news of the tariff agreement was met with a sharp rise in the Nikkei stock index, particularly boosting carmakers, signalling improved economic prospects. The improved trade outlook has rekindled expectations for further monetary tightening by the Bank of Japan (BoJ), which has been gradually exiting its ultra-accommodative monetary policy.

The 10-year JGB yield, considered the country's benchmark long-term interest rate, has surged over the past year. From around 0.80% in September 2024, the 10-year yield has risen to roughly 1.60% by July 2025, reflecting both the BoJ’s policy shift and improving economic confidence linked in part to trade developments.

The anticipation of BoJ rate hikes, partly driven by the easing of tariff tensions and stronger economic outlook, has supported higher long-term JGB yields. The key yield on 10-year Japanese government bonds reached 1.6% in Tokyo trading on July 23, 2020, which is the highest since October 2008.

The relief among investors may have contributed to the increase in bond yields. The safe-haven appeal of government bonds decreased due to the relief among investors. The selling spread in the JGB market increased as a result of the announcement of the reciprocal tariff agreement between the U.S. and Japan.

The market's response to the resolution of tariff negotiations suggests potential implications for Japanese monetary policy. An economist at an asset management firm stated that selling picked up due to the aforementioned speculation. The rise in the 10-year Japanese government bond yield occurred after U.S. President Donald Trump announced a reciprocal tariff agreement between the U.S. and Japan.

The easing of reciprocal tariffs on Japanese exports to the U.S. has bolstered market confidence, contributing to a rise in the 10-year Japanese government bond yield as investors price in stronger growth prospects and a tighter BoJ policy stance going forward. The tariff negotiations between the U.S. and Japan are no longer a source of uncertainty for investors and the market.

The easing of reciprocal tariffs on Japanese exports, as a result of the agreement with the U.S., has boosted market confidence in the finance industry, potentially leading to a rise in the 10-year Japanese government bond yield. This trade win, seen as a positive development in the business sector, is expected to have farther-reaching implications, such as further monetary tightening by the Bank of Japan (BoJ) in the media industry.
