BOJ's Bond Yield Move Causes Unexpected Market Turmoil

The Bank of Japan's decision to expand its target range for 10-year Japanese government bond yields caused a shock to global markets, resulting in a decrease in the value of bonds and stocks worldwide.

The Bank of Japan surprised investors by adjusting its Yield Curve Control (YCC) policy to permit the 10-year Japanese Government Bond (JGB) yield to fluctuate up to 50 basis points from its 0% target, an increase from the 25 basis points previously. This alteration is intended to soften the impact of prolonged monetary stimulus measures.

The Bank of Japan (BoJ) recently released a policy statement announcing their decision to take action in order to enhance the functioning of the market and ensure a more consistent yield curve. This move is meant to maintain the current accommodative financial conditions. The BoJ first implemented their yield curve control mechanism in September 2016 with the goal of increasing inflation to their 2% target after a long period of economic stagnation and low inflation.

The Bank of Japan (BoJ) is an exception among major central banks, as it left its benchmark interest rate at -0.1% on Tuesday and promised to significantly increase its 10-year government bond purchases, keeping its ultra-loose monetary policy. On the other hand, other central banks around the world are continuing to raise rates and tighten monetary policy in an attempt to control high inflation.

The YCC decision had a global impact, causing the Japanese yen and bond yields to increase while stocks in the Asia-Pacific region dropped. Japan's Nikkei 225 index closed 2.5% lower on Tuesday. The 10-year Japanese Government Bond yield briefly rose to 0.43%, its highest level since 2015.

By the morning hours in Europe, the U.S. dollar had dropped 3.3% in comparison to the rapidly increasing Japanese yen.

The yields on U.S. Treasury notes increased significantly, with the 10-year note rising to just below 3.66% and the 30-year bond increasing to 3.7078%. This is due to the inverse relationship between yields and prices.

At the start of the day, stocks in Europe dropped by 1%, as measured by the Stoxx 600. However, by the end of the morning, most of the losses had been recovered. Additionally, European government bonds were sold off, causing Germany's 10-year bund yield to rise by 7 basis points to 2.2640%. This was a jump from its earlier peak.

Susannah Streeter, a senior investment and markets analyst at Hargreaves Lansdown, commented that the decision is seen as a way to gauge the potential of withdrawing the stimulus that has been injected into the economy in order to stimulate demand and increase prices.

The Bank is still committed to its bond purchase program, asserting that this is simply a minor adjustment and not the beginning of a change in policy.

Mizuho Bank expressed a similar opinion in an email on Tuesday, noting that the market's activity reflects a sudden surge of bets on the Bank of Japan (BoJ) taking a more hawkish stance. However, the bank argued that this "popular bet" does not necessarily reflect the actual policy or the intended policy perception.

Vishnu Varathan, head of economics and strategy for the Asia and Oceania Treasury Department at Mizuho, stated that the Bank of Japan's recent move and communique do not alter their outlook that they will adjust policy to reduce the strength of the Japanese Yen, but not become overly aggressive.

Every effort was made to emphasize that policy accommodation is still in place, whether it was referring to the potential increase in bond purchases or the suggestion that there will be no further expansion of the YCC target band (at this time).

The Bank of Japan observed that since the beginning of spring, the level of market fluctuation had increased globally, and this had a considerable impact on the Japanese markets.

The performance of bond markets has declined, especially in terms of the comparison of interest rates of bonds with different maturities and the correlation between spot and futures markets, according to the report.

The central bank warned that if the current market conditions remain, it could have a detrimental effect on the ability of corporations to issue bonds.

On Tuesday, Luis Costa, the head of CEEMEA strategy at Citi, suggested that the market's reaction to the Bank of Japan's decision may have been too extreme. He told CNBC that there was "nothing remarkable" about the BoJ's choice.

It is important to consider the current positioning of the dollar-yen when looking at the Bank of Japan's recent measure. This adjustment was not anticipated, and should be seen as a minor change.

A Reuters poll conducted last week revealed that Japanese inflation is expected to reach 3.7% annually in November, which is the highest rate in 40 years. Despite this, it is still lower than the inflation rates seen in other Western countries.

According to Costa, the Bank of Japan's decision was not intended to fight inflation, but rather to address the "infrastructure and dynamics of Japanese Government Bond (JGB) trading" and the disparity in volatility between JGBs and the rest of the market.
