As of 09:33 GMT on Friday, December 19, 2025, global stock markets were leaning cautiously positive into the final full trading week of the year, with Asia closing higher, Europe treading water, and U.S. futures mixed as investors weighed three competing forces: a Bank of Japan rate hike, cooler-than-expected U.S. inflation data that may (or may not) be “real” after the U.S. shutdown, and persistent jitters about whether the AI spending boom can deliver profits fast enough to justify the sector’s valuations.

Asia stocks climb after Bank of Japan hike, but the yen slides
Asian equities advanced after the Bank of Japan raised its benchmark policy rate by 25 basis points to 0.75%, the highest level in 30 years—an expected move that still reverberated through rates, currencies, and risk sentiment. [2]
By the close in Asia:
- Japan’s Nikkei 225 rose 1.2% to 49,568.66
- Hong Kong’s Hang Seng added 0.4% to 25,610.50
- Shanghai Composite gained 0.5% to 3,895.75
- South Korea’s Kospi climbed 0.5% to 8,628.70
- Taiwan’s index was up 0.9% [3]
Yet the day’s most eye-catching move wasn’t in stocks—it was in foreign exchange. The yen weakened sharply after the BOJ decision, with the U.S. dollar rising as high as about 157.365 yen and last trading around 157.22, putting traders back on “intervention watch” ahead of thin holiday liquidity. [4]
Why would the yen fall after a rate hike? Markets judged the BOJ’s guidance as too vague to force a rapid repricing of Japan’s “still-low” rate path, which keeps the carry trade alive (borrowing yen cheaply to buy higher-yielding assets elsewhere). [5]
Europe holds near flat as banks support, tech lags on AI valuation worries
In Europe, trading was calm but constructive. At 09:32 GMT, the pan-European STOXX 600 was up 0.1% at 585.71, with Germany’s DAX up 0.2% and the UK’s FTSE 100 flat. [6]
Under the surface, leadership mattered:
- Banks and industrials were among the supports.
- Tech shares underperformed as investors revived concerns around AI valuations and the timeline for returns on huge infrastructure outlays. [7]
Policy messaging across Europe also reinforced the “late-cycle” feel:
- The European Central Bank held rates at 2.0% and signaled the easing phase may be nearing its end, even as officials stressed uncertainty around growth and geopolitics. [8]
- The Bank of England cut to 3.75%, but the vote was tight and the tone cautious—supportive for markets in the short term, but not an “all-clear” for aggressive cuts. [9]
A notable geopolitical headline also crossed traders’ screens: EU leaders agreed to fund Ukraine’s defense via joint borrowing, opting for a €90 billion loan rather than moving directly to seize frozen Russian sovereign assets. Bond market reaction was modest, with Germany’s 10-year yield up slightly on the day, and analysts split on the long-term implications for Europe’s fiscal toolkit and investor confidence. [10]
Wall Street futures mixed as Nike sinks, while chip strength extends
In U.S. premarket trading, futures suggested a muted open:
- S&P 500 futures: +0.06%
- Nasdaq 100 futures: +0.20%
- Dow futures: -0.03% [11]
Two big single-stock stories were steering the tape:
1) Nike slumps on China weakness
Nike fell sharply premarket after results highlighted pressure on margins and weaker China performance, dragging on the Dow complex. [12]
2) Semiconductors rebound after Micron reignites AI optimism
After an early-week wobble in tech, chipmakers regained momentum following strong signals from Micron, helping lift broader AI-linked sentiment—even as investors remain wary about whether the sector’s spending boom is getting ahead of itself. [13]
Corporate deal flow also stayed busy. Oracle rose after reports of binding agreements tied to ByteDance’s TikTok U.S. operations, reinforcing the sense that mega-cap tech remains both a market driver and a headline risk into year-end. [14]
One more reason traders were braced for intraday swings: “triple witching”, when stock options and index derivatives expire simultaneously, often amplifying volatility and late-day flows. [15]
The macro crosscurrents: inflation data, central banks, and the “shutdown fog”
A key driver behind the week’s rebound in risk assets has been U.S. inflation data that came in softer than expected. But there’s a major caveat: the recent 43-day U.S. federal government shutdown disrupted normal data collection and forced methodological workarounds—leaving investors unsure how much confidence to place in the latest readings. [16]
That uncertainty is showing up in the rates market:
- Markets implied only about a 24% chance of a Fed cut in January (per Reuters reporting and LSEG-based pricing references), while investors continued to debate the broader 2026 cutting path. [17]
- New York Fed President John Williams said he didn’t see an imminent need for another cut after last week’s move, underscoring that the Fed is not eager to “chase” noisy data. [18]
At the same time, a wide-ranging Reuters review of developed-market central banks suggests a broader shift: many major central banks are signaling that the rate-cut cycle is closer to its end than its beginning, even if individual paths diverge. [19]
This matters for equities because 2025’s rally—especially in U.S. mega-cap growth—has been tightly linked to the market’s ability to price a gentle landing, lower discount rates, and resilient earnings at the same time. When any one of those pillars looks shakier (inflation credibility, AI returns, geopolitics), volatility spikes fast.
Oil, copper, and gold: commodities flash mixed signals for 2026
Commodities sent a more cautious message than equities.
Oil stays under pressure on surplus fears and geopolitics
Oil prices were on track for a second straight weekly decline, driven by expectations of a potential supply glut and hopes tied to Russia–Ukraine diplomacy, even as traders monitored U.S.–Venezuela tensions and enforcement questions around a reported blockade stance. Brent traded around $59.73 and WTI around $56.02 in Reuters reporting, with both down more than 2% on the week. [20]
The takeaway for equity investors: lower energy costs can support consumers and margins, but persistent oil weakness can also signal softer global demand expectations—and it can weigh on energy-sector earnings and capex.
Copper pushes toward records on structural demand optimism
Industrial metals told a different story. Copper edged closer to record highs, with LME three-month copper near $11,837/ton as supply tightness came back into focus. Notably, Goldman Sachs reiterated a long-range view that copper could reach $15,000/ton by 2035, while other banks cautioned near-term upside may be harder from current levels. [21]
That divergence is important: copper is a bellwether for electrification and infrastructure demand, but prices at the top end can also tighten financial conditions for manufacturers and construction.
Gold steadies near highs as rate expectations wrestle with credibility
Gold eased modestly in global trading, holding near elevated levels after a huge 2025 run, with Reuters noting prices around $4,322/oz and an October peak near $4,381/oz. [22]
Gold’s resilience reflects a market that still wants hedges—against geopolitics, policy surprises, and the possibility that inflation cools less smoothly than investors hope.
The near-term outlook: Santa rally hopes, thin liquidity, and what to watch next week
With holidays approaching, investors are balancing optimism with caution.
Can markets still deliver a Santa rally?
Reuters notes that “Santa rally” season (the last five trading days of the year plus the first two of January) historically has been positive, but the setup into late December 2025 is more fragile than the headline year-to-date gains suggest. The S&P 500 is up more than 15% in 2025, yet December has been choppy, with AI-capex doubts and Fed-path uncertainty fueling big rotations between tech and cyclicals. [23]
The “data dump” after the shutdown could move everything
The next wave of U.S. releases—including GDP and confidence-related indicators—arrives with markets especially sensitive to “confirmation” about whether the economy is cooling gently or slipping faster. Reuters’ “Take Five” highlights that the post-shutdown backlog keeps traders from fully disengaging into the holidays. [24]
Currency volatility risk rises into the holiday period
The yen is a prime example: a large move in a thin market can create feedback loops across global risk assets, especially when the “intervention zone” is in view and carry trades are crowded. [25]
Bottom line
By 09:33 GMT on December 19, 2025, markets were leaning “risk-on,” but with a tight grip on the handbrake: Asia advanced, Europe hovered near flat, and U.S. futures were mixed as traders tried to reconcile a BOJ hike, murky post-shutdown U.S. data, and the ongoing debate over whether the AI boom is entering a healthier second phase—or flirting with an overshoot.
