Greenland opens, followed by the collapse of Japanese bonds, Trump TACO, yen intervention wraps up—“A week dominated by headlines” has ended.
In the past week, global capital markets seemed to be playing a "Russian roulette" game driven by headline news. From unexpected geopolitical threats to sudden shifts in monetary policy, a series of chaotic catalysts triggered sharp fluctuations in asset prices. In this shortened trading week that traders called "headlines rule everything," market sentiment swung repeatedly between extreme panic and rapid rebound, once again proving the fragility and unpredictability of the current macro environment.
The trigger for this week’s market turmoil began with Trump’s comments on Greenland and the subsequent tariff threats, which led to one of the most synchronized market selloffs since the pandemic. Next, the collapse of the Japanese bond market caused turmoil in the world's largest bond market, dubbed the "Truss moment" by the market.
Meanwhile, heightened tensions around Iran pushed up oil prices, and the battle for the next Fed chair increased uncertainty. However, as Trump later calmed the markets (the so-called "TACO" model), sentiment reversed, though this did not fully repair battered portfolios.
Ultimately, the week ended in an extremely divided landscape: stocks dipped slightly amid turmoil, volatility surged, the dollar suffered heavy losses, while precious metals broke out across the board to hit new highs. Although U.S. macro data posted the best two-week gain since last August, the market found no respite as a result.
On the contrary, the renewed breakdown in stock-bond correlations forced investors to reassess whether traditional risk-hedging strategies are still effective. This "roller coaster" market put investors in a dilemma: should such violent swings be seen as structural risks that must be hedged, or merely as yet another ignorable noise?
Chaotic Catalysts and Asset Divergence
The core feature of this week’s market was the overlap of multiple macro shocks.
First, Trump threatened to take "kinetic action" and impose tariffs on Greenland, prompting threats of retaliation from Europe.
Second, Japanese Prime Minister Sanae Takaichi’s "loose" policy and a weak bond auction triggered a collapse moment in the world’s largest bond market. Next, Trump once again displayed his TACO trait, telling the world that everything regarding Greenland and NATO "will be fine."
On Friday, the Bank of Japan’s "hawkish hold" was softened by talk of yield curve control, and forex traders became active on rumors of yen intervention.
Meanwhile, expectations for a Fed rate cut cooled sharply this week, and the market is now pricing in much less than two 25 basis point cuts.
Asset performance showed remarkable divergence:
In equities, the Nasdaq barely held on to modest gains, while other major indices closed down. This was the first time the S&P 500 posted two consecutive weekly drops since June 2025.
Goldman Sachs’ trading desk noted a "significant shift in Friday’s narrative," with the Russell 2000 underperforming the S&P 500 for the first time this year, ending a record 14-day winning streak.
Tech giants booked gains this week, strongly rebounding from Wednesday's TACO lows.
On the week, Mag7 stocks closed up, while the other 493 S&P components fell.
But Apple extended its losing streak to eight weeks, the longest since May 2022, with flows notably weaker than other tech giants.
The dollar took a heavy hit, with the dollar index dropping to its weakest level since August; the single-day drop was the biggest since August, and the weekly drop the largest since July.
The yen surged after intervention rumors, posting its biggest weekly gain since May 2025.
Gold rose for five consecutive days, up for three straight weeks and nearing $5,000.
According to Goldman’s Delta-One trading head Rich Privorotsky, "Clearly there's hot money involved, but first and foremost gold trading is by central banks... it's a slow erosion of the dollar's excessive privilege, not a sudden loss of confidence."
Silver broke through $100, hitting a peak of $103, rising eight of the last nine weeks.
In energy, oil prices soared due to geopolitical tensions.
Natural gas was most notable, surging over 85% from low to high within the week.
In bonds, Treasury yields were mixed, outperforming at the long end and lagging in the middle. Rate cut expectations dropped sharply this week, now well below two 25bps moves.
Hedging Dilemma: Should You Pay for Volatility?
Tuesday’s market performance was especially thought-provoking, as stocks, bonds, credit, cryptocurrencies, and emerging market assets all plummeted in unison that day.
According to Bloomberg, since 2020, major asset classes have fallen together on days when the S&P 500 loses at least 2% a total of 21 times—more than in the previous 15 years combined.
This kind of "double kill" in stocks and bonds made the traditional 60/40 portfolio (60% stocks, 40% bonds) fail again, suffering the biggest one-day loss since last October.
This phenomenon has sparked fierce debate on Wall Street about hedging strategies. Jeffrey Rosenberg, Senior Portfolio Manager at BlackRock Systematic Fixed Income, believes it’s not just headlines at play, but deeper shifts in market mechanisms.
He noted that since bonds have lost their reliability as a hedge against stocks, investors now face challenges of excessive asset concentration and failed stock-bond correlation, and are in urgent need of alternative diversification solutions.
Not everyone believes there’s a need to overreact. Mark Freeman, CIO of Socorro Asset Management LP, said he has never found hedging to be a particularly effective strategy, as it often amounts to making just another bet on short-term market moves. In fact, those betting on the resilience of the U.S. economy and the "TACO" effect have often achieved better returns over the past year.
Since the pandemic, concerns have grown that market reactions are becoming more synchronized, driven by structural changes: bonds no longer hedge stocks as before, crowded trades in tech amplify volatility, and global fiscal pressures limit policy buffers. Investors are not only dealing with volatility, but more frequent volatility as well.
Earnings Season Approaches, Markets Face a New Test
Even so, this week’s violent swings have clearly shaken the confidence of some investors.
In the latest fund manager survey by BofA, nearly half of respondents said they lack protection against a sharp stock-market drop, the highest ratio since 2018.
Chris Murphy, Co-Head of Derivatives Strategy at Susquehanna International Group, noted that while traders initially habitually chose to "buy the dip" and sell volatility, as the market rebounded, hedging activity in tech stocks increased noticeably ahead of earnings season.
Jim Thorne, Chief Market Strategist at Wellington-Altus, summarized that although the “TACO” effect may prove that taking on risk is reasonable, it doesn’t mean investors should “run naked” without their seatbelts on.
Accepting small, planned hedging costs to avoid catastrophic forced selling during synchronized market crashes may be a more rational choice in the current environment.
With the earnings season climax coming next week, tech giants such as META, Microsoft, Tesla, and Apple will release their results, and the market faces a new test: Will earnings stabilize the situation, or will yen strength and macro uncertainty continue to dominate risk asset pricing in this round?
