Japan Hikes Rates: Is the Cheap-Yen Era Ending?
The Bank of Japan has raised its policy rate by 25 basis points to 1.25%, the highest level in 31 years. The move passed by a 7-2 vote and was broadly expected by markets. The bigger question now is not the 1.25% level itself, but how far the BOJ is prepared to go from here.
This matters far beyond Japan. For years, the yen has been one of the world’s cheapest funding currencies. Investors could borrow at very low Japanese rates and move that capital into higher-yielding assets elsewhere — U.S. stocks, bonds, emerging-market currencies and other risk assets. That is the basic logic behind the yen carry trade.
As Japanese rates rise, that trade becomes less attractive. If the yen also strengthens, investors face both higher funding costs and FX losses. That is why every BOJ tightening cycle matters to global markets: the risk is not simply “Japan rates are higher,” but whether leveraged positions funded in yen begin to unwind.
The interesting part is that Japan’s latest inflation data do not look extremely hot on the surface. August core CPI rose 1.7% year over year, while the BOJ-focused measure excluding fresh food and fuel rose 1.9%. But import costs remain a concern, especially with energy prices elevated and the yen still relatively weak. Japan’s August imports jumped 28% from a year earlier, while the country posted a trade deficit of about ¥1.1 trillion.
So the BOJ appears to be acting before inflation pressure broadens again. The bank has signaled that it remains ready to keep raising rates if inflation risks persist. A recent Reuters poll showed economists expecting the policy rate to reach 1.75% by the second quarter of 2027, faster than previously anticipated. (Reuters)
That is why the yen itself may matter more than today’s headline hike.
Before the decision, USD/JPY was still around 156, even with markets already pricing a high probability of a rate increase. The next move will depend heavily on Governor Kazuo Ueda’s guidance and whether investors start bringing forward expectations for another hike. (Reuters)
If the BOJ says 1.25% is still far from the end point, the market may begin to narrow the expected U.S.-Japan rate gap more aggressively.
If it stays cautious, the yen may remain weak even after the hike.
For global investors, the most important risk is therefore not simply:
BOJ hikes → yen rises → stocks fall.
The more dangerous sequence is:
BOJ keeps tightening → yen strengthens quickly → carry trades unwind → leveraged global positions are forced to deleverage.
That is the scenario that could spill into U.S. tech, bonds and other high-beta assets.
Tiger View
Tiger thinks this rate hike matters because two assumptions that supported global liquidity are becoming less reliable at the same time.
The first was:
U.S. rates would eventually keep moving lower.
The second was:
Japan would always provide near-free funding.
Both assumptions are now under pressure.
That does not mean the yen carry trade is about to collapse immediately. Japan’s rate is still low in absolute terms, and markets can absorb gradual normalization if the yen remains orderly.
Tiger would watch three signals from here:
First: does the next BOJ hike get pulled forward?
Second: can USD/JPY move decisively below 150?
Third: do Japanese investors begin bringing more capital back home as domestic bond yields rise?
If the answer to all three starts turning yes, then this becomes more than a Japan story.
It becomes a global liquidity story.

Japan just raised rates to a 31-year high. What matters most next?
① Yen strength — USD/JPY breaks below 150
② Japanese banks keep benefiting
③ Carry-trade unwinds hit global markets
④ 1.25% is still too low to matter much

日本加息到1.25%，本身不意外，7比2的投票，市场早就消化了。1.25%的绝对利率依然很低，单看这个数字确实掀不起什么风浪。但核心问题不在利率水平，而在趋势。过去几十年，全球资金都在借便宜的日元，换成美元去买美股、美债和各种高风险资产。这就是套利交易。
现在日本央行开始收水，只要日元升值（比如USD/JPY跌破150），这些加了杠杆的仓位就会面临汇兑损失。为了止损，全球基金会被迫抛售美股来偿还日元借款。这种去杠杆一旦启动，就是连环踩踏，高估值的QQQ和科技股首当其冲。
至于日本银行受益（②），那是日本国内的事。出口商（比如丰田、索尼）会因为日元升值而利润承压。这些都是小逻辑。
所以我的操作很简单：别去赌什么日本银行股，也别急着去买日本出口商。盯死USD/JPY这个汇率。如果跌破150，我会立刻减仓手里的美股科技股，绝不留任何侥幸心理。现在不是去猜日本央行会不会继续加息的时候，而是防着全球资金被迫平仓的时刻。现金为王，随时准备应对流动性收缩。
Now imagine the Bank of Japan slowly pulling that block out with a pair of pliers.
When borrowing Yen suddenly becomes expensive, investors can't just sit on their hands. To pay back those newly pricey Japanese loans, global funds are forced to liquidate their winning positions elsewhere.
This means selling off US Treasuries, dumping high flying tech stocks & pulling liquidity out of crypto.
What should investors do?
Build a dry powder cash reserve which would allow you to buy quality stocks at big discounts.
Pivot to local strong stocks like $DBS(D05.SI)$ & a $OCBC Bank(O39.SI)$ . They act as anchors when the markets are volatile.
Stay calm & be patient.

I do not think this automatically means global tech stocks will fall. Japan’s rate is still relatively low, and gradual normalization should be manageable. The bigger risk is a sudden carry-trade unwind, forcing investors to reduce exposure across U.S. tech, bonds and other high-beta assets.
For now, I am watching BOJ guidance, USD/JPY and whether Japanese investors bring capital back home as domestic yields rise. If these signals move together, this could become a global liquidity story. I would stay patient and keep some flexibility rather than overreacting to the hike.

The BOJ’s 25bp hike to 1.25% was largely expected, so the headline move is less important than what comes next. The real risk is a faster unwind of the yen carry trade.
For years, investors could borrow cheaply in yen and deploy that capital into U.S. stocks, bonds and other higher-yielding assets. If Japanese rates keep rising while the yen strengthens, the equation changes: funding costs increase, while existing positions can also suffer FX losses.
That creates a potential deleveraging loop. Investors may sell risk assets not because their fundamentals suddenly deteriorate, but simply because leverage becomes more expensive.
So I’m watching USD/JPY, Japanese bond yields and BOJ guidance closely. If the yen strengthens rapidly, the BOJ story could quickly become a global liquidity story.
The key risk is not the 1.25% rate itself — it’s the speed of the unwind.
