Will Japan Sell US Treasuries? The Yen Repatriation Risk

Q: "Will Japan sell US Treasuries in 2026?"

" Japan appears to have begun trimming at the margin as it repatriates capital to defend the yen. On July 10, 2026 its finance minister asked the GPIF pension fund to shift toward domestic assets, and Japanese insurers have already ramped up buying of home bonds — funded partly by selling US Treasuries. A sudden, wholesale dump is unlikely; a slow, incentive-driven reduction is the more probable path."

Q: "How does Japan bringing its money home affect US mortgage rates?"

" Japan is the largest foreign holder of US Treasuries, near $1.1 trillion. If it buys fewer or sells, the US must offer higher yields to attract other buyers. The 10-year Treasury yield — near 4.7% in July 2026 — directly influences 30-year mortgage rates, so a Japanese pullback can nudge American borrowing costs higher even for people with no Japanese exposure."

Q: "Why is the Japanese yen collapsing?"

" The yen fell to roughly 160 per dollar in July 2026 — about a 40-year low — because Japan held interest rates near zero while the US paid around 5%, pushing money out of yen and into dollars. Because Japan imports nearly all its energy in dollars, a weaker yen also imports inflation, which pressures the currency further."

Q: "What is the yen carry trade unwind?"

" The yen carry trade is borrowing cheap yen to buy higher-yielding assets worldwide. It \u0026ldquo;unwinds\u0026rdquo; when the yen strengthens or Japanese rates rise, forcing investors to buy back yen and sell those assets — often quickly. Historically, fast yen rallies have accompanied global market stress, as seen in the August 2024 sell-off."

Will Japan sell US Treasuries? It increasingly looks that way. As of late July 2026, Tokyo is quietly steering its enormous pool of overseas savings back home to defend a collapsing yen — and because Japan is the single largest foreign holder of US government debt, that reversal could push American mortgage rates higher even for people who have never owned a Japanese asset.

The thesis comes from finance creator Andrei Jikh, who argues in a July 28, 2026 video that Japan is now being forced to choose between saving its currency and saving its bond market — and that its chosen fix, bringing capital home, lands directly on the US.

Key takeaways

The yen fell to roughly 160 per dollar in July 2026, its weakest level against the dollar in about 40 years, despite Japan spending an estimated $73 billion defending it and raising rates to a 1995 high.
Japan is the largest foreign holder of US Treasuries, sitting near $1.1 trillion, so if Japanese capital repatriates, a key buyer of American debt steps back.
On July 10, 2026 Japan’s finance minister asked the GPIF — the world’s largest pension fund at roughly $1.8 trillion — to shift from foreign assets toward Japanese ones; insurers have already flipped to their biggest buying of domestic bonds in three years.
Fewer foreign buyers means the US must offer higher yields; the 10-year Treasury near 4.7% feeds directly into 30-year mortgage rates.
Watch a rapidly strengthening yen: every fast yen rally since 1998 has coincided with a global leverage unwind.

Why the yen is breaking, and why it matters

For thirty years Japan ran the strangest economy in the developed world: near-zero inflation, near-zero interest rates, and government debt above 200% of GDP that never triggered a crisis. It worked because Japan owed the money mostly to itself — the Bank of Japan holds roughly 48% of all Japanese government bonds, with domestic insurers and banks holding most of the rest and foreigners under 8%.

That stability is now cracking. Post-2020 inflation reached Japan, wages started rising for the first time in decades, and the gap between US rates near 5% and Japanese rates near zero drove money out of the yen and into dollars. The result: the yen slid from around 110 per dollar to roughly 160 by July 2026 — a four-decade low. This is the endgame of the yen carry trade, the borrow-cheap-yen, buy-higher-yielding-assets trade that has quietly funded markets everywhere.

Save the currency or save the bond market

Japan’s dilemma is binary. Keep rates at zero and the yen keeps sinking, imported energy keeps getting more expensive, and a nation of savers gets poorer. Raise rates to defend the yen and the interest bill on 200%-of-GDP debt finally comes due, with the Bank of Japan bleeding losses on the bonds it owns. As covered in our piece on the Bank of Japan’s rate hikes, Tokyo tried a middle path — small hikes plus heavy intervention — and got the worst of both: the yen still fell and 10-year bond yields still climbed from a quarter of a percent in 2022 to about 2.7% in 2026.

The tell is a paradox. Japanese inflation came in at 1.6% — below the 2% target — yet bond yields kept rising anyway. That means the market is no longer trading inflation; it is trading a scarier question: with the government wanting to spend more and the Bank of Japan wanting to buy less, who is left to absorb all the new debt?

Will Japan sell US Treasuries to bring its money home?

Here is the mechanism that makes this a US problem. Rather than keep burning reserves buying its own currency, Japan is changing where its money lives — a process economists call repatriation. For the first time in a generation, Japanese government bonds actually pay something: the 30-year yields near 4%. A Japanese pension fund or insurer can now earn a guaranteed yield at home, in yen, with no currency risk.

On July 10, 2026, Japan’s finance minister asked the Government Pension Investment Fund (GPIF) — the largest pension fund on Earth at about $1.8 trillion — to move investments away from foreign assets and toward Japanese ones. That fund alone holds an estimated $230 billion in US Treasuries plus hundreds of billions in US stocks. Bloomberg data cited in the source video already shows Japanese life and casualty insurers flipping from net sellers of domestic bonds to their biggest buyers in three years — and the dollars to fund that buying come from selling US Treasuries.

So the answer to “will Japan sell US Treasuries” is that the selling appears to have started at the margin, driven by incentives rather than a single dramatic dump. For decades Japan was the most reliable customer at US bond auctions. If that customer steps back, Washington must attract new buyers the only way it can — by paying more. That is part of why the 10-year Treasury sits near 4.7%, close to cycle highs, and why your mortgage rate is partly set in Tokyo.

The crypto angle: Japan’s version of the CLARITY Act

Japan is also using incentives to lure capital home, and crypto is one of them. On July 20, 2026 Japan advanced reforms often compared to America’s CLARITY Act, legally recognising crypto as a financial asset that banks can hold, with a proposed tax cut on crypto gains from 55% toward 20%. The stated goal is not to pump tokens — it is to pull offshore Japanese wealth back onto regulated, yen-denominated domestic exchanges.

There is a second motive that mirrors the US stablecoin playbook. Just as dollar stablecoins have become major buyers of US government debt, Japan can let yen stablecoins be backed by Japanese government bonds — manufacturing a fresh buyer for the very debt no one else wants. It is the same debt-distribution logic behind the GENIUS Act’s stablecoin design, rebuilt for Tokyo.

A note of skepticism: “Article 589”

Part of the viral story rests on cryptic posts from an anonymous account claiming a Japanese legal provision, “Article 589,” will be used to claw yen loans back home. There is no confirmed policy, no official statement, and no verifiable source beyond that account — so treat it as unconfirmed rumour, not fact. The repatriation trend is real and documented; the specific legal mechanism circulating online is not.

What to actually watch

The real signal is not a weak yen but a suddenly strong one. In 1998, 2008, 2020 and August 2024, every fast yen rally coincided with global leverage unwinding — the carry trade snapping back and risk assets falling together. Those spikes were accidental. What makes 2026 different is that a stronger yen is now the stated goal of Japanese policy. If Tokyo succeeds in dragging its money home and the yen rips higher, history says something levered somewhere breaks.
