Biggest Macro Risk for Bitcoin Presents for the First Time Since 2006

For the first time since 2006, the Federal Reserve, European Central Bank (ECB) and Bank of Japan are all expected to raise interest rates within days of each other. The last time such coordinated tightening occurred, risk assets experienced sharp declines before eventually recovering.

2006 tightening and its impact on risk assets

In September 2006 the ECB raised its deposit rate to 2.50%. Futures markets later indicated a high probability of a Fed rate hike, and the Bank of Japan also moved to increase rates in May 2006. Within a month, major indices fell sharply: the S&P 500 dropped 7.7%, Europe’s Euro Stoxx fell 13.3%, Japan’s TOPIX slid 16.5%, and emerging‑market indices lost more than 20%.

The declines were driven by the end of cheap borrowing that had fueled broad market buying. When financing costs rose, the most leveraged positions were liquidated first. Despite the short‑term pain, the S&P 500 ended 2006 up nearly 16%.

How the 2024 environment mirrors 2006

Bitcoin (BTC) did not exist in 2006, but its price behavior this year shows a similar pattern. In August 2024 the Bank of Japan raised rates, the yen appreciated, and Japan’s TOPIX fell 12% in a single day. Bitcoin fell as much as 20% on the same day.

In the current cycle, Bitcoin behaves more like an emerging‑market asset. Japanese equities have already declined about 8.4% over the past month, suggesting the early stages of a funding squeeze.

Potential mitigating factors

Despite the tightening, Bitcoin has held above $79,000, breaking a downward trend seen earlier in 2024. Over the past year the cryptocurrency has fallen roughly 33%, trading around $77,900 at the time of writing.

One notable difference from previous cycles is the presence of U.S. spot Bitcoin exchange‑traded funds (ETFs). In August, these ETFs attracted $3.52 billion of inflows, more than offsetting the $5.30 billion that left over the prior seven months. This inflow represents capital that is not tied to yen‑denominated borrowing and could cushion the market against the upcoming rate hikes, provided the inflows continue.

Outlook

If daily fund flows remain strong, they may mitigate the immediate impact of the coordinated rate hikes. However, the combination of tighter monetary policy across three major economies re‑introduces the macro risk that historically pressured risk assets, including Bitcoin.
