Is Japan's Debt Level Causing Yen's weakness

The Japanese Yen (JPY) has been on a downward spiral since 2022, recently hitting a fresh 16-year low against the US Dollar (USD). While the Bank of Japan's (BoJ) recent move to end negative interest rates has contributed to the yen's weakness, a deeper dive reveals a more complex situation intertwined with Japan's towering debt levels.

Here's why the debt level of Japan is contributing to the Yen's weakness:

• Debt Level: Japan has extremely high debt levels, with public sector debt amounting to around 220% of GDP and total private + public sector debt exceeding 400% of GDP. This is significantly higher than other major economies.
• Cautious Central Bank:The Bank of Japan (BOJ) has been reluctant to raise interest rates aggressively due to concerns over widening the government's budget deficit further by increasing the cost of financing debt. Higher rates could also contribute to financial stress in Japan's highly indebted private sector.
• Yield Differentials: The BOJ's cautious approach to raising rates has resulted in Japan's real interest rates remaining deeply negative (around -3%) compared to other major economies where real rates are positive. This wide interest rate differential makes the yen less attractive to investors seeking higher yields. The large gap between U.S. and Japanese yields has made the yen the cheapest major currency to borrow and short-sell, contributing to its weakness. Traders expect the U.S. Federal Reserve to keep rates higher for longer, maintaining this yield differential.
• Rate Hike Pace: While positive inflation could help reduce Japan's debt burden over time, the BOJ has been cautious about raising rates too quickly to avoid disrupting the economy and government finances.

How Does Japan’s High Debt Level Compare To Other Countries

Japan has the highest public debt levels among developed nations. In absolute terms, Japan's public debt stood at around 1,286.45 trillion yen ($8.6 trillion) at the end of 2023, making it the largest national debt globally.

Over 40% of Japan's public debt is held by the Bank of Japan, as the central bank has engaged in massive quantitative easing and bond purchases to keep borrowing costs low.

Japan's total debt level, including private sector debt, exceeds 400% of GDP, significantly higher than other major economies like the U.S., Eurozone, and U.K., which have total debt around 250% of GDP.

Despite the extraordinarily high debt levels, Japan has been able to sustain this situation for decades due to several factors, including low borrowing costs, a domestic investor base, and the Bank of Japan's accommodative monetary policy.

However, Japan's debt servicing costs still consume around 22% of the national budget, and the country's aging population and low economic growth pose long-term challenges for debt sustainability.

What Are the Potential Risks of Japan’s High Debt Level

Japan's high debt level, exceeding 220% of GDP for the public sector and over 400% when including private debt, poses several significant risks to the country's economic and financial stability:

• Soaring Interest Costs: As interest rates rise globally, Japan's enormous debt becomes increasingly expensive to service. This could lead to a vicious cycle where higher interest payments exacerbate the budget deficit, forcing the government to borrow even more, driving rates up further.
• Crowding Out Private Investment: Government borrowing to finance its debt can crowd out private investment, as lenders prefer the perceived safety of government bonds. This can stifle economic growth by reducing investment in businesses and innovation.
• Loss of Investor Confidence: High debt levels can erode investor confidence in Japan's economy, potentially leading to capital flight, currency depreciation, and a decrease in foreign investment. This can further weaken the yen and make it more expensive to borrow money on international markets.
• Limited Fiscal Policy Space: Japan's high debt levels restrict the government's ability to use fiscal policy to stimulate the economy during downturns. This limits their options for addressing economic challenges and could lead to slower growth.
• Limited Options for Debt Reduction: While Japan has a long track record of managing its debt, it faces limited options for reducing it. Aggressive austerity measures could stifle growth, while relying on inflation to erode the value of debt is a risky strategy, particularly given the potential for runaway inflation.
