Foreign media reports that the US dollar has risen above 160 against the Japanese yen, drawing renewed market attention to whether Japanese authorities will intervene to stabilize the exchange rate and whether the Bank of Japan will continue to tighten monetary policy. The article argues that if this combination occurs simultaneously, it could compress global liquidity and amplify volatility in risk assets such as Bitcoin.

160 becomes a market warning line again.

In the foreign exchange market, 160 is considered a range closely watched by the Japanese government. The article mentions that Japan has previously intervened by selling dollars and buying yen when the yen weakened. Recently, Japan has used approximately 11.73 trillion yen (about 73 billion US dollars) to support the yen, demonstrating the government's high vigilance regarding exchange rate fluctuations.

With the Bank of Japan's meeting on June 15-16 approaching, the market is assessing the possibility of further policy tightening. If the yen continues to be under pressure, expectations of currency market intervention and interest rate hikes may rise simultaneously.

Why does a stronger yen put downward pressure on Bitcoin?

The article argues that the primary risk lies not in the exchange rate itself, but in the potential forced contraction of yen-funded transactions. In the past, some investors borrowed low-interest yen to allocate to other high-yield or high-volatility assets. Once the yen strengthens and financing costs rise, these positions tend to be the first to deleverage.

Such adjustments typically don't just stay in the foreign exchange market; they can also spread to US stocks and crypto assets. The article cites market observations stating that after the Bank of Japan's previous interest rate hikes, Bitcoin experienced significant declines, often exceeding 20%. The article also points out that these declines weren't solely caused by Japanese factors, but reflect Bitcoin's sensitivity to global liquidity tightening.

I'll be looking at two things over the next few days.

The article argues that the short-term focus is on two variables: whether the Japanese government will intervene directly in the foreign exchange market again, and whether the Bank of Japan will send a clearer tightening signal. If both factors combine, the pressure on carry trades may further intensify, and liquidity pressures on global risk assets will also increase.

As of the time mentioned in the article, Bitcoin has fallen significantly from its April high, with a cumulative decline of approximately 15% this month, and the price hovering around $62,900. Based on this, the article concludes that if the macroeconomic environment continues to tighten, the cryptocurrency market may remain highly volatile in the short term.
