On December 18, 2025, global markets turned cautious as investors questioned the scale and cost of the artificial intelligence boom, while silver prices surged to new heights, and fresh geopolitical moves from Washington and Moscow kept political risk firmly in view.
On the diplomatic front, the United States Congress pushed through a vast defense policy bill that locks in record military spending and signals a firm, long-term commitment to Kyiv and European security.
The new National Defense Authorization Act, worth about 900 billion dollars for the coming fiscal year, includes a pay raise for U.S. troops and several hundred million dollars in funding for Ukraine over the next two years, as well as resources to strengthen the defenses of the Baltic states. It restricts any significant reduction in the number of U.S. forces stationed in Europe and preserves the traditional command link between Washington and NATO, even as the Trump administration has taken a more skeptical tone toward long-standing alliances. Lawmakers from both parties backed the package, underlining how support for Ukraine and deterrence in Europe remain pillars of U.S. policy despite wider political divisions.
At the same time, President Donald Trump moved to tighten pressure on Venezuela by ordering a blockade on all sanctioned tankers carrying its crude in or out of the country. The directive follows the recent seizure of a sanctioned ship and a buildup of U.S. naval forces around Venezuelan waters.
The White House has also formally labeled the Caracas leadership and a circle of senior officials as a foreign terrorist organization, a step that adds to legal and diplomatic tensions. Venezuelan authorities condemned the move as a threat aimed at seizing control of the country’s large oil reserves. Energy analysts warned that if the measures are fully enforced for an extended period, they could remove a sizeable volume of crude from global markets and lift prices, although traders are watching to see how strictly the order is applied and how far a shadow fleet of tankers and other producers can offset the disruption.
In Europe, President Vladimir Putin warned during a meeting with Russia’s defense establishment that Moscow will push further into Ukraine if Kyiv and European leaders do not engage with proposals being discussed with Washington. He said Russian forces are advancing across several sectors of the front and reiterated that Moscow views Crimea and large parts of eastern and southern Ukraine as permanently Russian territory.
On the economic front, Wall Street’s main indices slipped, with the broad S&P 500 and the technology-heavy Nasdaq falling to roughly three-week lows as doubts resurfaced about the sustainability and eventual returns of huge capital spending on artificial intelligence. Big chipmakers and cloud-oriented technology names led the decline after signs that at least one multibillion-dollar data center project faces uncertainty and that some firms may become more reliant on debt to finance expansion.
At the same time, energy stocks advanced as crude prices rebounded more than 1%, reflecting fears that tighter enforcement of U.S. sanctions on Venezuelan oil could remove barrels from the market. However, policymakers offered a partial counterweight to the gloom, with Federal Reserve governor Christopher Waller stating that monetary policy remains restrictive and that the central bank still has space to cut rates if the labor market continues to cool.
In commodities, silver surged above 65 dollars an ounce for the first time, more than doubling since January, driven by a mix of heavy investment flows, a tight supply balance, and rising industrial demand from sectors such as solar, electric vehicles, and data centers, even as analysts warned that the metal’s history of sharp swings leaves it vulnerable to abrupt corrections.
In crypto, Bitcoin stayed under pressure after its recent crash, trading more than 30% below its October record around $126,000, near $85,000, while Ethereum hovered close to $2,800 and Solana traded around $120 as the broader crypto market continued to decline.
