Yields, Yen, and a Side of TACO

What happened last week in crypto and macro

By Akram Ayyash

The week ending January 26, 2026 delivered a masterclass in macro cross-currents. A once-sleepy Bank of Japan jolted global bond markets awake, the fabled yen carry trade began to shudder, and President Trump's latest geopolitical gambit over Greenland gave traders whiplash. Gold screamed to fresh all-time highs near $4,950 while risk assets teetered, leaving both Wall Street veterans and crypto participants scrambling to decipher the signals.

The core thesis: When the world's largest creditor nation begins normalizing rates while its government pivots toward fiscal expansion, the resulting bond market stress transmits globally through carry trade mechanics. Add a dose of policy uncertainty from Washington, and you get synchronized selling of both stocks and bonds, a breakdown in traditional diversification, and a definitive rotation into hard assets. Understanding these funding and flow dynamics is the key to navigating what comes next.

In this note, we break down how the BOJ's policy stance is reverberating globally, why the yen carry trade unwind is pressuring US assets, and how the emerging TACO ("Trump Always Chickens Out") pattern played out via a tariff threat and retreat.

The Yen Anchor Drifts

For decades, the Bank of Japan was the steady rock of ultra-loose policy. Not anymore. On Friday, January 23, the BOJ held its policy rate at 0.75% in an 8-1 decision, maintaining borrowing costs at their highest level since 1995. Board member Hajime Takata dissented, pushing for an immediate hike to 1.0%, arguing that the 2% price target had been sustainably achieved and that risks were skewing to the upside.

The hold was tactical, not dovish. Governor Ueda upgraded GDP forecasts to 0.9% for fiscal 2025 and 1.0% for fiscal 2026, while core CPI projections were nudged higher. The signal to markets: more tightening appears likely if activity and inflation evolve as projected.

But the real action was in JGBs. On Tuesday, January 20, Japan's 40-year bond yield rocketed past 4% for the first time since the maturity was introduced in 2007. The 30-year yield hit roughly 3.9%, a record. The 10-year touched 2.38%, a 27-year high. The jump in ultra-long yields of more than 25 basis points was the largest since the aftermath of Trump's Liberation Day tariffs last April.

What triggered the rebellion? Prime Minister Sanae Takaichi's announcement on January 19 that she would dissolve parliament and call a snap election on February 8, centered on a two-year suspension of the 8% consumption tax on food. With Japan's debt-to-GDP ratio near 240%, the prospect of unfunded tax cuts drew immediate comparisons to Liz Truss's ill-fated "mini-budget" in 2022. Bond vigilantes, sensing fiscal dominance, demanded higher yields to hold long-dated Japanese debt.

The repatriation math. Japan is the world's largest creditor nation, holding roughly $1.2 trillion in US Treasuries alone. For decades, Japanese institutions chased yields abroad since domestic returns were pinned near zero.

Now, the calculus has inverted. A Japanese life insurer buying a 10-year US Treasury and hedging the currency risk currently faces a net yield of approximately -1.57%. Compare that to 4% available in domestic 40-year JGBs. That's not a preference shift; it's an actuarial necessity.

Add to this an estimated $60 billion in unrealized losses sitting on domestic bond portfolios at Japan's major insurers, and you understand why "dry powder" is limited and sensitivity to further yield spikes is elevated.

The carry trade transmission. Closing a yen carry trade tends to force selling of foreign assets and corresponding yen buying to repay loans. We saw this dynamic Tuesday: as JGB yields spiked and the yen's slide paused around ¥158, there appeared to be a rush for the exits.

US bond markets felt it immediately. Treasury prices fell (yields up) in tandem with JGBs. The 10-year yield spiked to 4.3% as of January 20, a five-month high, before pulling back to around 4.24% by Friday as the immediate panic subsided.

Normally, when equities drop, we expect bonds to rally as a flight-to-quality. But a carry trade unwind can flip that script: investors sell both stocks and bonds to raise cash for deleveraging. That two-headed selloff is the last thing diversified portfolios want to see. And we got a taste of it Tuesday: as global equities slid, Treasuries also sold off rather than providing the usual safe-haven rally.

A structural solution on the horizon. While this week's JGB chaos dominated headlines, a longer-term development is worth flagging. SBI Holdings and Startale Group are on track to launch a fully regulated, yen-denominated stablecoin in Q2 2026.

These stablecoin issuers are poised to become meaningful buyers of JGBs as the BOJ tapers its bond-buying program. JPYC's CEO has predicted that stablecoin issuers could emerge as significant marginal holders of government debt, creating a "private-sector central bank" effect where tokenized money indirectly helps fund fiscal deficits. For crypto readers, this is the long-promised TradFi integration happening in real time, just not where most expected it.

The TACO Paradox and Arctic Volatility

Leave it to the President to throw a wildcard into an already fragile market.

On January 17, Trump announced a "National Security Tariff" of 10% on goods from eight European countries (Denmark, Norway, Sweden, Finland, France, Germany, the UK, and the Netherlands), escalating to 25% by June unless Denmark agreed to sell Greenland. He refused to rule out military force.

Markets immediately hit the risk-off button. When US markets reopened after the MLK holiday on Tuesday, the S&P 500 fell 2.1%, its worst session since October. The VIX spiked above 20. Gold surged. The selloff compounded the JGB spillover, creating a synchronized global risk-off event.

Then, within 24 hours, Trump walked it back. Speaking at Davos on January 21, he announced he'd formed "the framework of a future deal" with NATO Secretary General Mark Rutte on Greenland, effectively shelving the tariffs. The specifics remained vague, but markets didn't care. Stocks staged a V-shaped recovery, with the S&P rallying 1.2% Wednesday and adding another 0.8% Thursday. By Friday, the index was down only about 0.4% for the week.

This pattern has become so predictable that Wall Street gave it a name: the TACO trade (Trump Always Chickens Out). The playbook is simple: when Trump saber-rattles and markets tumble, buy the dip, bet on a reversal. It worked in April with Liberation Day tariffs. It worked in October with rare earth threats against China. It worked again this week.

But here's the paradox worth considering. From a flow-risk standpoint, trades built on behavioral certainty have a shelf life. If everyone assumes Trump will back down, markets might not drop enough to trigger the retreat. The market's confidence that "he always chickens out" could erode the very feedback loop that caused him to chicken out in the first place.

There's also a "point-proving" risk. As the TACO meme goes viral, the probability increases that the administration persists with a "bad" policy simply to defy the narrative. The BTD (buy the dip) strategy has worked, but it may have an expiration date. I'm not saying we're there yet, but the VIX settling around 16 by Friday (versus sub-15 readings in early January) suggests some residual uncertainty is being priced in.

Central Bank Credibility and the Haven Rotation

A third pillar of this week's volatility received less attention but may prove more durable: the escalating confrontation between the White House and Federal Reserve Chair Jerome Powell.

On January 9, the Department of Justice launched a criminal investigation into Powell regarding the $2.5 billion renovation of the Fed's headquarters, according to multiple reports. Powell responded with a video statement characterizing the investigation as a "pretext" for political pressure.

Former Fed chairs Janet Yellen, Ben Bernanke, and Alan Greenspan issued a joint statement warning that such prosecutorial approaches risk undermining Fed independence and, in the words of their statement, resemble monetary policy in "emerging markets with weak institutions." For global investors, the perceived risk of a politicized Fed appears to have contributed to "Sell America" flows, prompting diversification away from the dollar and into traditional safe havens.

This helps explain gold's explosive rally. As of January 23, spot gold hit a fresh all-time high near $4,950 per ounce, up roughly 8% for the month, the strongest start to a year since 2020. Silver broke above $100 for the first time. Platinum hit a record near $2,750. The rally reflects both safe-haven demand and broader sovereign rotation: central banks continue to accumulate physical gold as a hedge against institutional risk in the world's reserve currency.

Bitcoin, by contrast, struggled with its identity. During Tuesday's risk-off wave, BTC dropped below $90,000, briefly touching the high-$88,000s, behaving like a high-beta equity rather than a haven. By Thursday, as tensions eased, it clawed back to the $89,000–$90,000 range, where it consolidated into the weekend.

The divergence between gold and Bitcoin this week wasn't random. Gold is bought by central banks; Bitcoin is sold by whales. According to on-chain analytics providers, significant supply distribution occurred as BTC approached $100,000 in recent weeks, with large holders reportedly selling over $4 billion since late December. The $100,000 level isn't just a psychological barrier; it appears to be a supply unlock zone where long-term holders have released enough coins to overwhelm near-term demand.

Bitcoin ETF flows remained constructive (over $1.9 billion in net inflows in early January, per industry data), but spot selling from large holders has been sufficient to cap upside. Until sovereign or institutional accumulation of Bitcoin matches the structural buying supporting gold, the "digital gold" narrative may remain aspirational in risk-off environments.

Tidbits

Sovereign Tokenization at Davos: Binance co-founder CZ revealed at the World Economic Forum that he is in discussions with "probably a dozen" governments regarding tokenization of national assets. This "sovereign advisor" pivot suggests a new phase of adoption where nations leverage blockchain-based fractional ownership.

Strive's Treasury Play: Strive announced a $150 million preferred stock offering to expand its Bitcoin holdings. With over 12,700 BTC currently in its treasury, Strive continues replicating the "digital credit" playbook pioneered by Strategy.

BitGo's NYSE Debut: Digital asset infrastructure firm BitGo priced its IPO at $18 per share, valuing the company at approximately $2.1 billion. The successful raise signals continued institutional demand for regulated custody infrastructure.

What I'm Watching This Week

This week is loaded with potential catalysts. Prepare for elevated volatility.

Sunday Night/Monday Open: Markets will react to Trump's 100% tariff threat against Canada if Ottawa proceeds with its China trade deal. This is fresh as of Saturday and could set the tone for the week. Separately, prediction markets are pricing roughly 75% odds of a government shutdown, adding another layer of uncertainty.

Tuesday: January Consumer Confidence data. Watch for any deterioration in sentiment tied to tariff uncertainty or inflation expectations.

Wednesday (FOMC Day): The Federal Reserve announces its rate decision at 2pm ET, followed by Powell's press conference. Markets are pricing in a 95%+ probability of no change, but the tone of Powell's remarks will be critical. Any acknowledgment of global bond market stress (BOJ spillover) or hints about the DOJ investigation could move markets. This is the week's most important macro event.

Wednesday (Earnings): Microsoft, Meta, and Tesla report after the close. These are bellwether prints for AI capex, advertising demand, and EV/energy trends respectively.

Thursday: Apple reports earnings. Given its China exposure, any commentary on tariff risk or supply chain shifts will be closely watched.

Friday: December PPI inflation data. Hot prints could push back rate cut expectations and weigh on risk assets.

Structural Levels to Watch:

Gold at $5,000: A breach could signal sustained institutional rotation into hard assets.

Bitcoin's $90,000 pivot: A clean break above $92,000 with volume suggests consolidation is resolving higher; a breakdown below $88,000 indicates more deleveraging ahead.

USD/JPY at ¥155: A break below this level could accelerate carry trade unwinds.
