#数字资产动态追踪 Unforeseen Market Shock: Narrowing US-Japan Interest Rate Differential, Why Is the Yen Still Depreciating?

As global markets fluctuate, the foreign exchange market is playing out a scenario beyond textbook expectations.

The US-Japan interest rate differential has shrunk to its lowest point since 2022—2.09%. Meanwhile, Japanese government bond yields have surged to 2.07%, reaching a new high since 1997. According to conventional financial theory, this should be a golden window for the yen to strengthen. But reality has defied all expectations: the US dollar against the yen has not fallen; instead, it has been rising, catching market participants off guard.

Behind this breakdown of logic lies Japan’s ever-growing mountain of debt. Japan’s government debt exceeds 230% of GDP. For every one percentage point increase in government bond yields, the burden of debt interest payments rises sharply. As a result, investors are reading a different signal: Japan’s debt system may already be overwhelmed. Amid spreading panic, capital votes with its feet, and this is the true driver behind the yen’s continued depreciation.

The triple shackles of the yen’s decline: First, US bond yields remain high, with the real interest rate differential still favoring the dollar; second, carry trade remains hot, with ongoing borrowing of yen to buy dollars; third, the Bank of Japan’s ambiguous stance and unclear signals make it difficult to stabilize expectations.

Looking ahead, three key points will determine the direction of this game—when the Federal Reserve will truly start cutting rates, whether the Bank of Japan will give clear hints of rate hikes, and whether Japanese government bond auctions will face cold reception. The current situation is already clear: debt risks have surpassed traditional exchange rate principles and are becoming the core lever for shifting global capital allocation.

Debt explosion really is incredible; Japan's current situation is a fatal blow that has been hit. --- Once again, it's the carry trade messing things up. When will borrowing in yen ever come to an end? --- A debt ratio of 230% and still raising interest rates? Even the Bank of Japan must be stunned. --- So, traditional theories are a joke here; now it's all about who can sustain their debt. --- When the interest rate differential narrows, the yen depreciates. I know this trick too well—it's the phase of bullish frenzy. --- Waiting to see when the Federal Reserve will act—that's the real key. Everything else is just smoke and mirrors. --- If the Bank of Japan can't meet expectations and capital starts fleeing, it's all over. --- If government bond auctions face cold reception, the yen will truly be doomed.

Debt-to-GDP ratio of 230%, this is the Achilles' heel of the yen. The theory is really worthless in the face of reality. --- Once again, it's a carry trade trick. If the Bank of Japan doesn't intervene soon, the yen will continue to fall. --- Honestly, now it's more accurate to judge the exchange rate by debt ratios rather than interest rate differentials. This time, the market has been taught a lesson. --- That mountain of debt in Japan will eventually collapse. Right now, it's just a sign of capital fleeing in advance. --- The Fed's rate cut is key, but more than that, I care more about when the Bank of Japan will give a clear signal. --- Carry trades have been exploiting the yen. As long as U.S. Treasury yields remain high, the yen will continue to depreciate. --- The cold reception to government bond auctions is the real alarm. That's when Japan will realize what it means when no one is willing to buy.

Debt really can reverse the entire game rules... Japan is now a living textbook Carry trades are still crazy, how can the yen possibly rise? Honestly, who cares about interest rates The central bank's attitude is so vague, I’m worried for investors Japan's debt is 230% of GDP... this number makes me a bit suffocated Reality is always harsher than theory, the textbook needs to be rewritten Profits have never come from following logic, but from following panic Let's wait and see the Fed's next move, this is the real chip Yen depreciation? This is what debt is saying Triple shackles tightly lock in, where is the breakthrough? The dollar remains strong, and behind it are so many messy accounts

Japan's debt mountain is so high that no wonder the yen can't hold up... Carry trades are still continuing to exploit profits, it seems there's no short-term rescue The central bank signals are vague = funds are directly fleeing, this logic is actually very cruel The Federal Reserve remains inactive, the Bank of Japan is just playing around, the yen will probably continue to be battered Debt risk outweighs the exchange rate rule, this time it's really a game over rhythm Debt ratio of 230%... Tsk tsk, this position is a bit uncomfortable Rather than waiting for the central bank to rescue the market, it's better to turn around early; the US dollar is still attractive

The debt card is played, and the theory collapses... Can Japan really not hold on anymore? --- The carry trade is still ongoing, and the yen can't stabilize. --- Wait, debt exceeds 230% of GDP? That number makes my scalp tingle... No wonder investors are fleeing. --- The US dollar continues to be popular, and if the Bank of Japan keeps being ambiguous, it will really be over. --- So, the most disgusting issue is still debt; the interest rate spread has become a mere formality. --- The key is to see when the Federal Reserve will actually cut rates; otherwise, the yen will continue to be hammered. --- Haha, textbook theories are being slapped in the face by reality. That's how financial markets are. --- The Bank of Japan should give a clear stance; don't keep the market so suspenseful.
