Japan's taxes on the rise: what threat for Bitcoin

The Bank of Japan (BoJ) is preparing to tighten its monetary policy, raising interest rates up to 75 basis points, the highest level in the past 30 years. According to Nikkei reports, this decision marks a critical moment for global markets and could exert downward pressure on Bitcoin, which is currently priced at $66,960 with a 2.02% decline in the last 24 hours.

BoJ Raises Japanese Rates: Context of the Decision

The planned increase will raise the benchmark rate from 0.50% to 0.75%, a 25 basis point jump expected by the end of December 2024, marking the first hike since January of the same year. This move is an attempt by the BoJ to normalize monetary policy after a prolonged period of near-zero rates, a situation Japan has experienced for over three decades.

The yen, currently trading around 156 per US dollar, could strengthen further in response to this monetary tightening. A stronger yen has historically coincided with downward pressure on Bitcoin and other high-risk assets, as it prompts investors to reconsider their international carry trades.

Yen Carry Trade: Risk Mechanism for Bitcoin

To understand how Japanese rates influence Bitcoin, it’s essential to explain the yen carry trade mechanism. For decades, hedge funds and trading desks have systematically borrowed yen at ultra-low—often negative—interest rates to finance investments in high-beta assets, mainly US tech stocks, government bonds, and cryptocurrencies.

This strategy was profitable as long as the interest rate differential between Japan and the US was wide. When the BoJ raises rates, the cost of these loans increases, making carry trades less attractive. The result could be a massive unwinding—investors liquidate risky positions to buy back yen and reduce debt exposure. Such a scenario would trigger a risk-off wave in global markets, with Bitcoin particularly vulnerable due to its sensitivity to liquidity conditions.

July 2024 Precedent: When Rate Hikes Caused a Crash

History provides clear evidence of this risk: on July 31, 2024, the BoJ increased rates to 0.5%, sparking a sudden rally in the yen and a massive risk-off wave in early August. During that period, Bitcoin plummeted from around $65,000 to $50,000 within days. This precedent fuels current fears that further Japanese rate hikes could repeat the same scenario.

The yen’s strength at that time compressed global liquidity conditions—a dynamic Bitcoin is especially exposed to. High-volatility assets and related carry trades faced simultaneous pressure, creating a negative multiplier effect.

Is This Time Really Different? Analyzing the Current Scenario

However, today’s market environment shows significant differences that could mitigate the negative impact of Japan’s rate tightening. Two key factors deserve attention:

A bullish speculative base on the yen: Unlike mid-2024, when large speculators monitored by the CFTC held bearish yen positions, current sentiment is already bullish. This means the market may have already priced in the BoJ’s rate hike, reducing surprise and shock effects.

Japanese Treasury yields have led official rates: Throughout 2024, Japanese government bond yields (JGBs) reached multi-decade highs across short and long maturities. The BoJ’s rate increase thus aligns with market expectations already embedded, rather than being a regulatory surprise.

Meanwhile, the US Federal Reserve has taken the opposite path: this week, it cut interest rates by 25 basis points to a three-year low and introduced additional liquidity measures. The dollar index has fallen to weekly lows, indicating a global environment of reduced liquidity scarcity. Taken together, these factors suggest a relatively low probability of a significant yen carry trade unwinding or widespread risk aversion in the coming weeks.

Japan’s Fiscal Risk: A Need for Vigilance

Beyond this immediate decision, a long-term issue warrants constant monitoring: Japan’s fiscal situation. With a debt-to-GDP ratio of 240%, the country has the highest debt level among developed economies.

Under Prime Minister Sanae Takaichi’s administration, Japan is pursuing significant fiscal expansion and tax cuts while inflation hovers around 3%. Meanwhile, the BoJ continues to keep rates relatively low, operating as if the country is still stuck in deflation. This mix—rising inflation, extremely high debt, low official rates, and fiscal stimulus—creates a potentially unstable recipe.

MacroHive, a macroeconomic analysis agency, summarized the risk as follows: with inflation expectations rising and the BoJ’s credibility in question, global investors might start reassessing Japan’s status not as a safe haven but as a fiscal risk territory. In such a scenario, JGB yields could rise further, the yen could weaken, and Bitcoin might find new appreciation potential—unless the global environment deteriorates sharply.

In conclusion, while Japanese rates are indeed rising and warrant close watch, the December 2024 environment presents enough differences from the summer’s shock to advise caution in expecting a repeat of August’s turmoil. The real long-term threat lies not just in the BoJ’s immediate rate moves but in the sustainability of Japan’s overall fiscal and monetary model—a dynamic that will continue to introduce volatility for Bitcoin and global markets in the months ahead.
