This might not be Christmas, but the war in the Middle East is over — at least according to U.S. President Donald Trump.

On Monday, Trump declared at the Knesset, Israel’s parliament, that the “long and painful nightmare” was finally over for both the Israelis and Palestinians. More straightforwardly, Trump gave an unequivocal “yes” when asked by reporters if the war in the Middle East has ended, Reuters reported.

A similarly hopeful mood permeated markets, though for different reasons. After hitting China with 100% additional tariffs and triggering a sell-off on Friday, Trump appeared to walk back his stance, posting on Truth Social that “it will all be fine” with China.

And thus was TACO back on traders’ menus: Major U.S. stock indexes rebounded, with technology stocks leading the charge. Quantum computing names popped after JPMorgan Chase announced it will be investing $10 billion in sectors crucial to national interests.

Broadcom, meanwhile, surged almost 10% after it jointly announced a partnership with — who else? — OpenAI to build and deploy custom chips. But where this puts Nvidia, OpenAI’s other near and dear one, and on whose chips the ChatGPT maker relies, remains a question.

Though Christmas has yet to arrive, OpenAI is starting to look like the tech sector’s Santa Claus.

War in the Middle East is over, Trump says. At Israel’s parliament, Trump gave a speech in which he said that the “long and painful nightmare” for both the Israelis and Palestinians was over. He also urged, at a separate event, for leaders to put “old feuds” behind.

Broadcom joins the OpenAI party. The two companies announced Monday that they’re planning to develop and deploy OpenAI-designed chips, amounting to 10 gigawatts, starting late next year. Shares of Broadcom popped almost 10% on the news.

JPMorgan says it will invest $10 billion in critical industries. The four areas of focus — which the bank considers crucial to U.S. security — are: defense and aerospace, “frontier” technologies such as AI, energy technology and supply chain and advanced manufacturing.

Stocks claw back some losses. On Monday stateside, major U.S. stock indexes rose, rebounding from Friday’s carnage. The S&P 500 regained 56% of Friday’s decline. Europe’s Stoxx 600 index climbed 0.44%, lifted by mining stocks.

[PRO] European sectors less affected by trade war. The continent isn’t in the crosshairs of Trump’s latest tariffs, but a weakening U.S. dollar could affect Europe’s exports. UBS picks three sectors more shielded from that — leaving out a notable one.

The U.S. has stepped in with an extraordinary bailout of Argentina. Here’s what it means

In a move that Treasury Secretary Scott Bessent announced Thursday on social media site X, the U.S. is providing a $20 billion currency swap line with Argentina’s central bank — essentially exchanging stable U.S. dollars with volatile pesos.

The move comes amid liquidity concerns in Argentina that threatened stability for the country as it faces key midterm elections. There are equal parts economic and political stakes with the venture, which marks the first U.S. intervention of this nature since rescuing Mexico in 1995.
