Official data showed core consumer inflation, which excludes fresh food prices, rose 1.4% year-over-year, matching both market expectations and April’s reading. It also marked the fourth consecutive month below the BOJ’s 2% inflation target, largely due to government subsidies that continue to offset higher energy costs.

At the same time, headline inflation edged up to 1.5% from 1.4% in April, while a closely watched measure that excludes both fresh food and energy slowed to 1.8%, suggesting underlying price pressures are easing.

Despite the softer inflation data, the outlook remains uncertain.

The BOJ recently raised interest rates to 1%, the highest level since 1995, warning that rising producer prices and higher energy costs linked to the Middle East conflict could eventually feed through to consumers. Japan’s producer price inflation jumped 6.3% in May, signaling that businesses are facing mounting cost pressures that may later appear in retail prices.

For investors, the picture remains mixed:

• Core inflation stayed below the BOJ’s 2% target
• Government fuel subsidies continue to limit price growth
• Producer prices are rising sharply
• The BOJ has signaled it remains open to further rate hikes

While inflation has stayed relatively subdued so far, many economists expect it to accelerate later this year as higher energy and import costs gradually filter through the economy.

In mid-January, the yield on Japan’s 40-year government bond jumped above 4 percent for the first time in more than 30 years. That move may sound technical, but it matters because Japan has a $7.5 trillion bond market that plays a key role in global finance. When Japan’s bonds become unstable, the shock can spread to the US, Europe, and beyond.

Here is what is happening and why it matters.

What Changed in Japan

For many years, Japan’s central bank kept interest rates extremely low and bought huge amounts of government bonds. This kept borrowing cheap and bond prices stable, even though Japan has one of the highest debt levels in the world.

That system is now changing.

The Bank of Japan has started to reduce its bond purchases and allow market forces to set prices more freely. At the same time, inflation has returned after decades of deflation, which naturally pushes interest rates higher.

Then politics added more pressure.

Prime Minister Sanae Takaichi announced a large stimulus package and promised to suspend the food sales tax for two years. These plans could cost the government around 5 trillion yen per year and may require more borrowing.

Investors now fear that Japan will issue many more bonds in the coming years. When supply rises and buyers are scarce, bond prices fall and yields rise quickly.

Why Demand Is Weak

Japan’s central bank used to be the biggest buyer of its own bonds. Now that it is stepping back, there are not enough domestic buyers to replace it.

Local life insurers and pension funds, which traditionally bought long-term bonds, have reduced their buying because prices are swinging too much. Some insurers have already reported large paper losses on their bond holdings.

Foreign investors now dominate trading in Japanese bonds. They are fast to enter and fast to exit. When yields jumped, many cut their positions, making the sell-off even worse.

Why This Affects the Whole World

Japan’s bond market is deeply connected to global markets.

First, when Japanese long-term yields rise sharply, investors sell bonds in other countries to rebalance their portfolios. This week, US, UK, and Canadian bond yields all rose after Japan’s move.

Second, Japan is a major funding currency. Investors often borrow cheap yen to invest in higher-yield assets abroad. When Japanese yields rise, these trades become less attractive and are unwound, hurting stocks and bonds worldwide.

Third, Japan has long been a symbol of stability. When that stability cracks, investors become more cautious everywhere.

Is Japan in Crisis

No, Japan is not close to default. Most of its debt is held domestically, and the government can still borrow.

The real issue is not solvency. It is volatility and credibility.

Markets are learning that Japan is no longer protected by heavy central bank support. Prices can now move freely, and fiscal promises matter much more.

As one economist put it, Japan is not collapsing. It is simply being priced by markets again after many years of artificial calm.

What Comes Next

The Bank of Japan has said it may slow the pace of its withdrawal and step in if markets become disorderly. For now, it is letting yields rise.

Investors will closely watch:

• The upcoming election and new spending promises
• Whether the central bank intervenes
• Whether foreign investors keep selling

The key message for global markets is simple.

Japan is back on investors’ radar, not because it is failing, but because its bond market can now move fast and shake the entire financial system.

The post Why Investors Are Worried About Japan’s Bond Market first appeared on Finblog.

According to reports from Bloomberg and Japan Times, the BOJ will sell small portions each year, about ¥330 billion ($2.2 billion) based on book value, to avoid shocking financial markets. At this pace, the process could take decades to complete. The plan was approved at the central bank’s September policy meeting, where officials emphasized stability and minimal disruption.

Why This Matters

The BOJ’s ETF holdings have ballooned to ¥83 trillion ($534 billion) after years of large-scale asset purchases meant to stimulate growth and fight deflation. Selling them now signals confidence in Japan’s economic recovery, but also introduces a new phase of monetary tightening.

Markets are already on edge ahead of the BOJ’s December 18–19 policy meeting, where a rate hike to 0.75% is widely expected, the highest in nearly two decades. That move would further strengthen the yen and reduce Japan’s role as the world’s go-to source of cheap borrowing.

Impact on Global Markets

A BOJ unwind means less liquidity globally. Japanese investors may pull money back home as yields rise, reducing demand for US and European assets. Stocks could face mild pressure, while the yen might strengthen.

What It Means for Crypto

The news has already rippled into crypto markets. Bitcoin (BTC) fell nearly 3% after the BOJ reports, as traders brace for tighter liquidity worldwide. For years, easy monetary policy in Japan supported risk assets like crypto. A shift toward tightening could weigh on speculative investments short term.

However, analysts note that over the long run, reduced central bank intervention could bring healthier market conditions — favoring assets with real demand and scarcity like Bitcoin.

In short: The BOJ’s gradual ETF selloff may seem slow, but it marks the end of an era of free money, one that’s bound to reshape both traditional markets and the crypto landscape in 2026.

The yield on the 30-year Japanese Government Bond (JGB) fell four basis points to 3.38% after the Ministry of Finance’s auction drew a bid-to-cover ratio of 4.04, the highest since 2019 and well above last month’s 3.125. The strong turnout followed a solid 10-year auction earlier this week, where investors also stepped in as yields reached attractive levels.

Before the auction, 30-year yields had touched 3.445%, the highest since the maturity was introduced in 1999, while the 10-year yield climbed to 1.92%, its highest since 2007.

Ryutaro Kimura, senior fixed-income strategist at AXA Investment Managers, said the unexpectedly strong demand reflected renewed confidence in the super-long end of Japan’s bond market. “Many investors considered it acceptable to increase exposure to super-long bonds when yields exceeded 3.4%,” he said. “This outcome provided reassurance to those worried about an unending rise in rates.”

The auction’s tail, the gap between average and lowest accepted prices, narrowed to 0.09 from 0.27 last month, further signalling robust demand.

BOJ Rate Hike Bets Intensify

The surge in demand comes despite hawkish remarks from BOJ Governor Kazuo Ueda, who said the central bank would “weigh the pros and cons of lifting rates” while keeping financial conditions accommodative. Swaps now imply an 80% chance of a BOJ rate hike at its December 18–19 meeting, up from 56% a week ago, with over 90% odds priced in for January.

Minoru Kihara, Japan’s chief cabinet secretary, said the government is “closely watching” long-term rate moves and assessing their potential economic impact.

Fiscal Policy and Global Impact

Investors are also monitoring the government’s upcoming fiscal 2026 budget, amid worries that Prime Minister Sanae Takaichi’s ¥20 trillion (US$135 billion) stimulus package could fuel higher borrowing needs. The Ministry of Finance recently announced plans to raise short-term debt issuance by adding ¥300 billion to two- and five-year note auctions and ¥6.3 trillion to Treasury bill supply.

Traders said pension funds and foreign investors helped drive the latest rally in long-term JGBs, even as life insurers remained cautious buyers. Stephen Spratt, rates strategist at Société Générale, said, “This 30-year auction should cool things down after a frenzied few weeks in regional bond markets.”

Still, analysts warn Japan’s bond market remains fragile. “Although the latest auction was firm, we need to see consistent buying before declaring stability,” said Shoki Omori, chief desk strategist at Mizuho Securities.

The rally eased immediate pressure on Japan’s debt market but underscored a larger shift: the world’s third-largest economy is entering its first serious tightening cycle in nearly two decades, one that could ripple across global bond markets.

The post Japanese Stocks Rally, Bond Sale Sees Solid Demand first appeared on Finblog.

Long-term Japanese Government Bond (JGB) yields have jumped to their highest levels since the 2000s, the yen is sliding toward intervention levels, and investors are suddenly talking about a possible unwind of the famous “yen carry trade.” At the same time, Japan’s new government has approved a huge 21.3 trillion yen stimulus package, the biggest since the pandemic, which is pushing worries about debt and inflation even higher. (Japan $135 B Stimulus Made Yen Fall and Markets Tremble)

All of this matters not only for Japan, but also for US bond markets, global stocks and even Bitcoin.

Let’s break it down step by step.

What are JGBs and bond yields?

A Japanese Government Bond (JGB) is simply an IOU (I owe you) from the government of Japan. The government borrows money by issuing a bond, pays a fixed coupon every year, and repays the face value at maturity. JGBs have maturities from 2 years to 40 years and are considered very low credit risk, similar to US Treasuries.

Bond yield is simply the yearly return an investor gets if they buy the bond today and hold it to maturity. When bond prices fall, yields rise, and vice versa.

Because JGBs are the backbone of Japan’s financial system, their yields matter for:

• The interest rate Japan pays on its enormous public debt
• Mortgage and corporate borrowing costs inside Japan
• Global investors who use the yen as cheap funding
• Pricing of other bonds around the world

Two key points:

• Bond price vs yield move in opposite directions. If investors start selling bonds and the price falls, the yield (the effective interest rate the government pays to new buyers) climbs.
• Higher yields mean higher borrowing costs. When the 10 year JGB yield rises, Japan has to pay more interest as it refinances old debt with new bonds at today’s higher rates.

Japan’s bond market is huge. Government bonds outstanding are worth around 8 trillion dollars equivalent, which makes JGBs one of the largest and most important bond markets in the world.

Why Were Japanese Yields So Low For So Long?

For decades, Japan was the world champion of low or even negative yields. That was not an accident. It was the result of four big forces working together historically.

Deflation after the 1990s bubble: After the property and stock bubble burst in the early 1990s, Japan fell into a long period of weak growth and falling prices. When prices decline, even a zero yield can feel “OK” because your cash can buy more next year. There was very little pressure to push interest rates higher.

Aging population and high savings: Japan has one of the oldest populations in the world. Older households tend to save more and spend less. High savings and low consumption put downward pressure on prices and interest rates. Domestic investors were happy to hold safe JGBs even with tiny yields.

Massive central bank intervention: The Bank of Japan (BoJ) became the biggest buyer of JGBs on the planet. Starting in the early 2010s it launched huge quantitative easing (QE) programs, buying bonds in the open market and flooding the system with yen. By 2020, the BoJ owned around half of all JGBs outstanding.

Later it introduced Yield Curve Control (YCC). Under YCC the BoJ promised to keep the 10 year JGB yield around zero, buying unlimited amounts of bonds if yields tried to move too high. That policy pinned long term yields close to zero for years.

Very little inflation: Unlike the US or Europe, Japan struggled to generate inflation. Consumer price growth was often below the BoJ’s 2 percent target. With weak inflation and weak growth, there was no rush to raise rates.

Put together, these factors created a strange world where ten-year JGB yields hovered near zero and sometimes dipped below, even while other countries offered much higher rates.

For global investors, Japan became:

• A source of nearly free money
• A stable anchor that kept global yields suppressed

This is where the yen carry trade and Japan’s global importance come in.

Why Would Anyone Buy A Negative Yielding Bond?

It sounds irrational to lend money to the government and guarantee a loss if you hold to maturity. Yet huge institutions still bought JGBs.

Here is why.

Capital safety and regulation: Pension funds, insurers and banks must hold a lot of safe assets. JGBs are treated as risk free in regulation and can be used as collateral. Sometimes the priority is not return, but simply making sure the money is there when retirees need it.

Currency reasons: A foreign investor might buy a JGB even at a small negative yield if they expect the yen to strengthen. A stronger yen can more than offset the tiny negative coupon when measured in dollars or euros.

Riding the BoJ: If you know the central bank is a huge buyer at almost any price, you can buy JGBs and later sell them to the BoJ at a profit, even if the headline yield is negative. Traders can still make money on price moves.

So JGBs stayed in demand, and yields stayed pinned to the floor.

The quiet giant behind global markets

Japan is the world’s second-largest net creditor. Japanese households and institutions have accumulated trillions of dollars in foreign assets over decades.

Two key channels mattered for the world:

The yen carry trade

For many years, Japan’s interest rates were close to zero, while those in the US, Europe, and emerging markets were much higher.

So investors did the obvious:

1. Borrow cheaply in yen
2. Convert those yen to dollars or other currencies
3. Buy higher yielding assets, like US Treasuries, corporate bonds, tech stocks, emerging market bonds, and even crypto
4. Earn the yield difference as profit, as long as the yen stays weak and funding is cheap

This is the yen carry trade. It works as long as: Yen funding is cheap, the yen does not strengthen too much, and Global risk assets keep rising.

Because the trade is often leveraged many times, even small moves in yields or exchange rates can force rapid selling.

Japan as a major buyer of foreign bonds

Japan also became one of the most important buyers of US Treasuries and other sovereign bonds:

• Japan’s holdings of US Treasuries have usually been around one trillion dollars, often the largest or second largest foreign holder.
• Japanese life insurers and pension funds liked US bonds because domestic yields at home were near zero.

In US Treasury auctions, foreign buyers show up as indirect bidders. Analysts and official data have often linked large chunks of this foreign demand to Japanese institutions.

In simple terms:

Japan’s zero rate world was like a standing promise to the globe:
“We will keep lending cheaply and buying your bonds.”

That promise is now changing.

What Changed In 2024–2025?

After years of fighting deflation, Japan finally got what it wanted: inflation above target and rising wages. Unfortunately it arrived together with huge public debt, a weakening yen and political pressure to support households with more spending.

Several things happened almost at once.

BoJ started normalising policy: The BoJ ended negative rates in 2024 and gradually relaxed Yield Curve Control. It also slowed its bond buying. With the central bank stepping back, natural market forces started to push yields higher. Ten year JGB yields climbed toward and above 1.8 percent in late 2025, the highest since before the global financial crisis in 2008.

Long term yields spiked: Twenty, thirty and forty year JGB yields jumped sharply. The forty year yield approached record highs around 3.7 percent in November, reflecting investor worries about long term inflation and Japan’s ability to manage its huge debt load.

A huge stimulus package: The new Takaichi government approved a 21.3 trillion yen economic package, including 17.7 trillion in extra budget spending, 2.7 trillion in tax cuts and extra defence and crisis management outlays. Officials say it should lift GDP by about 1.4 percentage points per year for three years and cut headline inflation by around 0.7 point next year through energy subsidies. More about: Japan $135 B Stimulus Made Yen Fall and Markets Tremble

Here is how this links to yields and debt.

Bigger deficits and higher JGB yields: The government is financing a large part of the package by issuing more bonds. Investors know Japan already has debt above 250 percent of GDP, the highest in the developed world. More supply, plus a less aggressive BoJ, means markets demand higher yields to absorb all this paper. Long-dated JGB yields, especially those of 20, 30, and 40 years, have jumped as a result.

The “sell Japan” mood: As yields rise, the yen weakens, and stocks wobble, some global investors talk about a “sell Japan” trade. They worry Japan is moving from a very stable, low-yield, low volatility system to something more like the UK in 2022 when a surprise fiscal package triggered a bond sell-off. Articles in global media now compare Japan’s situation to that British gilt crisis, warning that markets are testing how far Japan can push its debt and stimulus.

Bond market no longer sleepy: For years, the JGB market barely moved. Now, volatility is the highest in two decades, and analysis from Bloomberg shows US Treasuries are more sensitive to moves in Tokyo than before. Japan’s nearly eight trillion dollar bond market has effectively “woken up,” and it is shaking other markets with it

Now markets see something:

• Japan already has the highest debt to GDP ratio in the developed world.
• More stimulus means more bond issuance, at a time when the BOJ is buying fewer bonds and interest rates are rising.

Where yields stand now (and why it matters)

Here is a simplified picture of how far JGB yields have moved.

Approximate JGB yield levels

Why Japan Matters So Much For US Bonds

On the surface, Japan’s direct holdings of US Treasuries are about 1.1 trillion dollars, just a slice of a forty trillion dollar US bond market. That sounds small. The real story is about flow and who the marginal buyer is.

For more than twenty years:

• Japanese exporters earned large trade surpluses in dollars
• Domestic rates in Japan were near zero
• US Treasuries yielded 2 to 4 percent more than JGBs

So Japanese institutions routinely recycled their extra dollars into US Treasuries and other foreign bonds. In many long term US auctions, indirect bidders (foreign buyers) regularly took 60 to 80 percent of the bonds, and analysts estimate Japan was often a very large part of that bid.

In plain language: Japan was often the biggest regular customer at US Treasury auctions.

Now the math is changing.

• JGB yields are rising closer to US yields
• The cost of hedging dollar exposure back into yen is high
• Japan sometimes needs to sell dollars to support the yen

So instead of buying more Treasuries, Japanese investors are slowing purchases or even selling some holdings. At the same time the US is running large fiscal deficits and needs to issue more debt.

Why this matters: When your biggest regular customer stops showing up, you have to find new buyers. Those new buyers usually only step in if yields are higher. That is why many analysts expect US long-term rates to drift 2 to 3 percentage points higher over the next few years compared with the last decade, even if inflation falls.

Higher US yields mean:

• More expensive mortgages
• Lower valuations for high growth tech stocks that rely on low discount rates
• Tighter financial conditions globally

Analysts already see this shift in the data:

• US Treasury statistics show changes in foreign holdings, including Japan’s stock of Treasuries trending lower in recent years.
• Japan’s Ministry of Finance reports swings in cross border flows as Japanese investors trim foreign bond purchases.

The yen carry trade unwind

Higher JGB yields and the risk of a stronger yen are bad news for the yen carry trade.

Remember, the trade is:

• Borrow in yen at low rates
• Use it to buy risk assets elsewhere

If: Yen funding costs rise, and the yen starts to strengthen, then leveraged funds suddenly face: Higher interest bills, Potential currency losses

To protect themselves, they often cut positions fast. That means selling the most liquid things they hold: US mega cap tech stocks, Global index futures, Gold, Bitcoin and other large crypto coins

This is why you often see days where JGB yields spike and almost everything risky sells off together.

How This Links To Crypto And Bitcoin

Crypto might feel very far from Japanese government bonds, but the connection runs through liquidity and risk appetite.

Stimulus and liquidity:
Japan’s stimulus and continued low short term rates still add liquidity to the global system. That can be supportive for Bitcoin when investors feel comfortable taking risk.

Bond yields and carry trade stress:
However, rising JGB yields and fears of a carry trade unwind can create sudden deleveraging. When large funds have to close yen funded positions, they often sell whatever is liquid: US stocks, gold, and crypto.

We already saw an example. After the latest Japanese stimulus announcement, Bitcoin dropped below 84k dollars and briefly touched around 83.3k, with nearly two billion dollars of crypto positions liquidated in 24 hours. Analysts tied part of that move to worries about the yen, higher Japanese yields and global risk aversion.

Two opposite forces for Bitcoin:

• A weaker yen and more stimulus can push some Japanese savers toward assets like Bitcoin to protect purchasing power
• But if higher yields trigger a global sell off and carry trade unwind, crypto can fall together with other risk assets

So Japan’s bond market is both a potential tailwind and a serious risk for crypto, depending on how the story evolves.

Why this matters for ordinary investors and the real economy

You do not need to trade JGB futures to be affected by this.

Here is how the Japan bond story can spill into the everyday world:

1. Higher global long term rates: If Japanese demand for US and European bonds fades, yields in the US and Europe may need to be higher to attract replacement buyers. That can mean more expensive mortgages, higher corporate borrowing costs and pressure on stretched equity valuations.
2. More volatile markets: A potential carry trade unwind can cause sudden swings in global equities and currencies. Even diversified portfolios can feel that volatility.
3. Pressure on overvalued assets: High growth tech stocks and speculative crypto projects are most sensitive to rising discount rates and tighter liquidity. They face double pressure from both higher yields and reduced risk appetite.
4. Policy dilemma for Japan
   The Japanese government must juggle three conflicting goals:
   • Keep debt affordable
   • Protect households from inflation
   • Avoid a market panic in bonds and currency
   The BOJ must decide how far it can tighten without breaking the system. This uncertainty itself adds risk.

What to watch next

If you want to track how the Japan story evolves, a few simple indicators can tell you a lot:

Putting it all together

Putting everything together:

Japan was the world’s “free money machine” for decades: Zero rates and constant BoJ buying kept its yields low and made it cheap to borrow yen and invest elsewhere. That helped keep global yields down and supported risk assets everywhere.

Now that machine is reversing:

• Inflation is above target
• The BoJ is slowly stepping back
• The government is borrowing more through stimulus
• Investors are demanding higher yields to hold JGBs

Higher Japanese yields mean:

• Potential repatriation of Japanese money from US and European bonds
• Upward pressure on global interest rates
• Risk of a yen carry trade unwind if the currency strengthens
• More volatility in stocks, credit and crypto

In other words, Japan’s bond market is no longer a sleepy corner of global finance. It is one of the main drivers of the risk environment

This is why traders keep repeating one simple line:

“Watch JGB yields. If Japan moves, the world moves.”

For now, the story is still unfolding. The next few BOJ decisions, and how investors digest Japan’s stimulus and rising yields, will tell us whether this is a manageable adjustment or the start of a much bigger global repricing.

Summary

Japan kept global interest rates artificially low for twenty years. Its central bank bought massive amounts of bonds and kept yields near zero. That allowed investors to borrow cheap yen and buy risk assets everywhere. This fuelled carry trades into US stocks, bonds and even crypto.

Now yields in Japan are finally rising, and the free money era is ending. The biggest quiet buyer at US bond auctions is stepping back, the yen carry trade is under pressure, and markets are suddenly re pricing risk. From here, everything depends on whether Japan can stabilise its bond market around slightly higher, but still manageable, yields or whether the move turns into a bigger unwind that forces selling across global assets.
