A look at the day ahead in U.S. and global markets from Mike Dolan

Darkening skies over Europe's economy, trade and politics sent the euro plummeting to its lowest in two years - just 3% from dollar parity - as post-election U.S. crypto optimism sees Bitcoin flirt with $100,000 for the first time.

Round figures often act like magnets for financial markets.

But what appears like a perfect storm over the euro zone - and its biggest economy Germany in particular - has seen the sharpest monthly move in the world's pivotal Transatlantic exchange rate in two years.

Facing potential trade wars with both the United States and China, a ratcheting up of geopolitical tensions to its East, creeping energy prices and a German election early next year, the euro's 4% fall so far in November is its biggest monthly loss since April 2022 - the month after Russia invaded Ukraine.

With another set of dire business surveys showing German and euro zone activity contracting this month, the euro plunged to two-year lows of $1.033 on Friday. And pressure is mounting on the European Central Bank to accelerate its easing just as the Federal Reserve hesitates with further rate cuts stateside.

Money markets are now leaning towards a fourth ECB rate cut of the year next month of as much as 50 basis points to 2.75%, while futures still see little more than a 50% chance the Fed will move at all next month.

At just shy of 230 basis points, the two-year U.S.-German bond yield gap is at its widest since 2022 as well.

Alongside the latest gloomy business surveys, Russia's increasingly pointed nuclear threats and extraordinary missile strikes on Ukraine this week have jarred the continent anew as Moscow eyes the isolationist stance of Donald Trump's incoming U.S. administration as an opportunity to bolster its position.

And European wholesale gas prices hovered near annual highs after fresh U.S. sanctions on Russia's Gazprombank raised fears over what remains of gas supplies from Russia, just as cold temperatures led to drawdowns in Europe's gas stores.

But the prospect of Trump catalyzing global trade wars in which Europe would be left most exposed was perhaps the biggest economic cloud gathering.

In the starkest warning so far from the ECB about the consequences of a trade war, the central bank's chief economist Philip Lane said on Thursday that global economic output would suffer a "sizeable" loss, while any immediate boost to inflation would fade over a few years.

The euro's losses, meantime, have catapulted the dollar higher across the planet - with the dollar index also hitting its best levels since 2022 and now up more than 6% for the year to date. China's yuan briefly hit its weakest since July.
