Recently, the actions of global central banks have left people stunned—while the Federal Reserve cuts interest rates, the Bank of Japan suddenly hikes rates, two moves in completely opposite directions. Many are starting to speculate: what’s going on? Are central banks around the world beginning to do their own thing?

Calm down, it’s not that simple.

Why is the Fed cutting rates? Essentially, it’s because economic data isn’t looking great—corporate borrowing pressures are high, and employment figures are starting to weaken. Cutting rates is like relieving pressure on the market, making money cheaper so companies can finance at lower costs, giving the economy some breathing room. But here’s the problem—when money becomes cheap, liquidity overflows, and funds tend to flow from traditional channels into high-risk sectors like stocks and cryptocurrencies. After the first rate cut last year, major cryptocurrencies saw a quick surge, leading many to chase the highs, only to be wiped out by volatility later—that’s the logic.

So why is the Bank of Japan doing the opposite? The key lies in "interest rate spread adjustment." For a long time, the US-Japan interest rate differential was huge, leading to large amounts of international capital arbitraging by borrowing low-yield yen and investing high-yield dollars (known as "carry trades"). If this capital inflow becomes too large, it causes the yen to depreciate continuously, which can push up domestic inflation in Japan. Therefore, the BOJ raising rates is essentially tightening this arbitrage space to prevent excessive imbalance.

It may seem contradictory, but these actions are actually about maintaining a certain balance in global capital flows. The Fed loosening monetary policy to stimulate the economy, and Japan tightening to prevent capital flight and runaway inflation—one stepping on the accelerator, the other on the brake, both aiming to stabilize their respective financial systems.

For the crypto market, in the short term, it might benefit from the dollar liquidity easing, but don’t forget—Japan’s rate hike could cause some leveraged funds to flow back, potentially amplifying volatility. The key takeaway remains: don’t go all-in chasing the rally; managing your positions is more important than betting on the direction.
