Japan Is Repeating a Rare Policy Experiment That Rocked UK, Turkey, and US Markets

Japan’s government is pushing public pension funds to buy more domestic assets, even as the Bank of Japan raises rates and trims its bond holdings. Japan’s policy split now pits fiscal stimulus against monetary tightening.

Finance Minister Satsuki Katayama said this week that Japan wants the Government Pension Investment Fund and other public funds to lift their home holdings. The goal is to steady bonds and the yen while the BOJ pulls back.

Japan’s Policy Split is Deliberate

The Government Pension Investment Fund manages about $1.8 trillion, making it the world’s largest. Close to half sits in foreign stocks and bonds, so even a small shift home moves global markets. The push follows earlier calls from lawmakers to invest more at home.

That signal landed on hot inflation. Producer prices climbed 7.1% in June, up from 6.6% in May, official data showed. Oil, electricity, and plastics drove the gain, and rising inflation usually lifts bond yields. Instead, the 10-year yield fell 10 basis points to 2.775% after the pension news.

The BOJ, meanwhile, has lifted its policy rate to 1%, the highest since 1995, and keeps buying fewer bonds.

🚨 BANK OF JAPAN RATE HIKE ALERT!The Bank of Japan is expected to raise interest rates to 1% this June.If it happens, it will be the first time since 1995 that rates reach this level.This hawkish move could have a major impact on the Japanese $JPY and global markets. pic.twitter.com/0wgWh6bNwh

The government is moving the other way. Prime Minister Sanae Takaichi is planning consumption tax cuts and cash handouts funded by fresh debt. Japan felt this in January, when its 40-year yield first topped 4% in a record bond selloff.

“Japan is now tightening policy, shrinking its balance sheet, and expanding fiscal spending, all at the same time, this has never happened before,” analyst Bull Theory observed.

History Warns How This Can End

Other governments have tried mixing fiscal expansion with monetary tightening. Few episodes ended quietly.

In September 2022, the United Kingdom’s £45 billion mini-budget hit markets while the Bank of England was hiking. The 30-year gilt yield jumped about 120 basis points in days as leveraged pension funds sold to meet margin calls.

During the Liz Truss mini-budget crisis (late September to early October 2022), the 10-year UK gilt yield spiked to a peak of approximately 4.5–4.6% before the Bank of England’s emergency bond-buying intervention calmed markets.Today 10-year UK gild yield is 5.17%.Just saying. pic.twitter.com/ZesiAz6DLh

The bank had to intervene with an emergency backstop, and Prime Minister Liz Truss resigned after 49 days.

Turkey shows the slower version. President Recep Tayyip Erdogan pressed for rate cuts during high inflation and replaced the governors who resisted. The lira lost about 44% in 2021, and inflation later topped 85%.

Turkey is the cautionary tale. Erdogan swapped economists for loyalists and forced low rates. Result: inflation peaked at 86%, still painfully high. That’s the movie you don’t want a sequel to. Posting the full interview over on my fledgling youtube channel:…

The tension is old. In 1951, the United States Treasury-Fed Accord freed the Fed from years of cheap-debt support.

It had pinned long-term yields near 2.5% to fund World War II, the textbook case of fiscal dominance.

During the deficit explosion of WW2, the Fed did YCC from 1942 to 1951 to avoid soaring yields. It only ended with the Treasury-Fed accord of 1951. The alternative, of course, is USD devaluation. https://t.co/TEiXobG8lP

Why Crypto Markets Should Care

Japan matters to digital assets through the yen carry trade, where investors borrow cheap yen to buy higher-yielding assets abroad. Estimates put it at several trillion dollars.

After the BOJ raised rates in July 2024, that trade unwound fast. In early August, the Nikkei 225 fell 12.4% in one session, its worst since 1987. Bitcoin (BTC) sank below $50,000.

The setup looks familiar. Yen short positions recently hit their highest level since 2024. Analysts also warn Japan’s bond market could threaten the cheap-money rally in stocks and crypto. Japan holds the developed world’s heaviest debt load, more than double its output, leaving little room for error.

Whether Japan can absorb rising debt without a shock may hinge on how much its pension funds actually buy, and how long the BOJ keeps tightening. Markets that once ignored Tokyo now watch every signal.
