(Bloomberg) — US President Donald Trump’s announcement of new tariffs on eight European countries over Greenland weighed on risk sentiment as trading kicked off Monday.

Futures on the Euro Stoxx 50 slumped 1.3%, while those on the S&P 500 dropped 0.8% as of 6:36 a.m. in London. US cash markets will be closed for a holiday Monday. The dollar weakened against all its Group-of-10 peers, losing the most against the Swiss Franc as traders sought haven assets. The euro reversed early losses to trade higher.

Trump on Saturday announced a 10% tariff as of Feb. 1 on goods from European countries that have rallied to support Greenland in the face of US threats to seize the semi-autonomous Danish territory. He said the levies would increase to 25% in June unless and until “a Deal is reached for the Complete and Total purchase of Greenland.”

The announcement drew a quick rebuke from European leaders including French President Emmanuel Macron, who intends to request the activation of the European Union’s anti-coercion instrument — the bloc’s most powerful retaliatory tool. The European Union is in talks to potentially impose tariffs on €93 billion ($108 billion) of US goods, if Trump follows through on the threat of the 10% levy.

“In the near term, any surprise escalation via tariffs on Europe could trigger a classic risk-off episode, especially after a strong start to the year supported by constructive sentiment,” said Florian Ielpo, head of macro research at Lombard Odier Asset Management. “In that scenario, government bonds could benefit, quality assets would likely outperform, and gold could catch a bid.”

Shares of automakers were down on Tradegate in early trading on Monday, with Porsche SE, Volkswagen AG and Mercedes-Benz Group all sliding more than 3%. Defense stocks were headed higher, with Rheinmetall AG up 1.2%.

The impact is likely to be on equities in the short-term and less obvious for bonds and currencies, according to Vincent Mortier, chief investment officer at Amundi SA. The US holiday on Monday also suggests thinner market conditions and no Treasury cash trade overnight.

The fallout from the news “could have some negative impact on European growth prospects but most probably on a very limited scale,” Mortier said. “Longer term, that could be a positive catalyst for Europe to accelerate its strategic autonomy agenda and form new alliances.”

Trump’s tariff threat could prove an unwelcome interruption to the rally in European equities, which have outperformed their US peers as investors poured into various regional sectors from defense to miners and chip-equipment makers. The region’s outlook has been boosted by increased German fiscal spending, lower interest rates and expectations of improving profits.

“Futures are down as the nervousness is palpable. All in all, you have so many issues piling up — from credit cards to the independence of the Fed and tariffs — that I really don’t see the case for stock markets to keep on breaching new records,” said Alexandre Baradez, chief market analyst at IG in Paris. “This is actually a time when investors might be tempted to cut risk and take some profits.”

Since the start of 2025, the Stoxx Europe 600 has climbed 36% in dollar terms, double the S&P 500’s gains over the same period. The European benchmark now trades at nearly 16 times forward earnings, above its average over the past 15 years and narrowing its discount to US peers to about 30%.

“The year had started pretty well across financial markets but this new situation may trigger some profit taking,” said Vincent Juvyns, chief investment strategist at ING in Brussels. “If one looks strictly at the raised tariffs, it’s something that economically could be absorbed but the possibility of a break within the Western world would have consequences that I fail to measure the scale of.”

Citigroup Inc. strategists led by Beata Manthey have previously estimated that a 10% tariff on Europe should result in a 2 to 3 percentage-point drag on European earnings-per-share growth.

The picture is worse for those most exposed to the US levies. A Goldman Sachs Group Inc. basket of exposed companies including shipping firm A.P. Moller – Maersk A/S, carmaker BMW AG and electrical-equipment maker Legrand SA was barely changed last year, while the Stoxx 600 rallied 17%.

Luxury goods, carmakers as well as miners were among sectors that came under pressure after Trump’s “Liberation Day” in April. Stocks exposed to international value chains, such as consumer discretionary and everyday goods, could also be impacted.

Still, any reaction might be short-lived until there’s more clarity on the situation. Defense stocks could also rally, said ING’s Juvyns, limiting the scope of a selloff.

“The fact that this threat was on social media instead of distilled into an executive order and it has a delayed implementation means a lot of investors might just decide to wait things out before overreacting,” said Brian Jacobsen, chief economic strategist at Annex Wealth Management.

That could prove the case especially for the euro, with Deutsche Bank AG predicting a limited fallout for the regional currency, in part because of how much the US relies on Europe for capital. The tariffs could also be a catalyst for greater EU political cohesion, further meaning any negative fallout on the euro against the dollar may not be sustained this week.

“From our perspective the key thing to watch over the next few days will be whether the EU decides to activate its anti-coercion instrument by putting measures that impact capital markets on the table,” George Saravelos, Deutsche’s global head of FX research, wrote in a note to clients. “It is a weaponization of capital rather than trade flows that would by far be the most disruptive to markets.”

Here is what market participants are saying:

Michael Brown, senior research strategist at Pepperstone:

“My working assumption is that an ‘off ramp’ from these threats will soon be found, and that this turns into yet another ‘TACO moment’, or an example of the ‘art of the deal’, depending on how one views these things. Against that backdrop, with the fundamental bull case for risk still a resilient one, and providing that any European retaliation remains largely rhetorical, I would view equity dips as buying opportunities for now.”

Francisco Simón, European head of strategy at Santander Asset Management:

“The key element to watch in the coming days is whether the message translates into formal measures or remains purely rhetorical, which would make a clear difference in the market reaction. In the very short term, we interpret this announcement more as a source of political noise than an economic shock. It introduces a slightly higher risk premium on European assets, particularly exporters and the euro, but with a still limited probability of immediate implementation.”

Andrea Tueni, head of sales trading at Saxo Banque France:

“I don’t know if the impact will be as high as last April when US tariffs were announced but it will be negative, that’s for sure. The obvious sectors that will be hit will be luxury, wine and spirits. Another factor which increases the uncertainty is that US markets will be closed and that means investors won’t have that compass during trading.”

Guillermo Hernandez Sampere, head of trading at asset manager MPPM:

“Markets are sensitive to the dynamic developments regarding new tariffs as a basis for negotiating security issues. Rising uncertainty, as seen last year, will weigh on all markets. The forum starting today in Davos will reflect the current situation.”
