Markets Rally on Biden's Election Edge, Central Bank Stimulus

The threat of regulation and taxes had receded, and investors would be forced to jump back in.
Markets rallied on the belief that a divided Congress would prevent aggressive new policies.

In the days following America's 2020 election, global financial markets found an unexpected kind of solace in political ambiguity. The prospect of a Biden presidency checked by a Republican Senate — a government divided against itself — was read by investors not as dysfunction, but as protection: a shield against sweeping regulation and the fiscal disruptions that accompany bold governance. Amplified by the Bank of England's announcement of £150 billion in fresh stimulus, markets from Tokyo to London rose, as if uncertainty, properly framed, could itself become a form of reassurance.

  • Global stocks surged — Asia up 2%, Europe up 0.8% — as investors interpreted a likely divided U.S. government as a barrier against corporate tax hikes and aggressive regulation.
  • The bond market delivered its sharpest single-day signal since the pandemic's onset, with 10-year Treasury yields plunging 11 basis points as expectations for heavy government spending collapsed.
  • Tech giants like Amazon, Facebook, and Google leapt 6–8%, embodying the market's relief that the regulatory threat hanging over the sector appeared, for now, to have receded.
  • Oil's brief 4% surge gave way to profit-taking, a reminder that the euphoria of gridlock has its own half-life — Brent crude slipping back below $40.50 by Thursday.
  • Beneath the rally's surface, a quiet burden was being transferred: with Congress unlikely to act boldly, the Federal Reserve and global central banks would be left as the sole architects of economic support.

The morning after America's election, financial markets around the world were already drawing their own conclusions. In London, Sydney, and across Asia, exchanges opened higher — not because the outcome was certain, but because the shape emerging from the returns felt, to investors, like a manageable one. A Biden presidency paired with a Republican Senate suggested a government too divided to move aggressively, and markets, which often fear change more than stagnation, responded with relief.

Asian stocks climbed 2%, reaching their highest levels since early 2018. Japan's Nikkei rose to a nine-month peak. South Korea and Chinese blue chips followed, the latter buoyed by hopes that a Biden administration might soften the tariff regime of the Trump years. In Europe, the FTSEurofirst gained 0.8%, aided by the Bank of England's announcement of an additional £150 billion in bond purchases — a signal that central banks remained willing to act where governments might not.

The bond market's message was even starker. The 10-year Treasury yield fell from 0.93% to 0.74% in a single session — the largest such move since the panic of March 2020. The logic was simple: less government spending meant less bond supply, and less bond supply meant higher prices. Tech stocks surged 6–8% on the expectation that sweeping regulation would stall in a divided Congress. Fund managers who had retreated to safety before the election began moving back into risk.

Currency and commodity markets told a more nuanced story. The dollar steadied after a volatile night. Sterling recovered despite lingering Brexit uncertainty and whispers of negative interest rates at the Bank of England. Oil, which had jumped 4% on Wednesday on gridlock optimism, quietly retreated as profit-taking set in.

Portfolio managers called it a "goldilocks scenario" — stable enough to feel safe, loose enough to stay liquid. But the comfort rested on a fragile premise: that central banks, already stretched by pandemic-era intervention, could carry the full weight of economic support if Congress chose inaction. The rally was real. So was the question it left unanswered.

The morning after America's election night, financial markets across the globe were reading the returns as a kind of relief. In London and Sydney, stock exchanges opened higher. Bonds rallied. The Bank of England had just announced it would pump an additional 150 billion pounds into its bond-buying program, and investors were interpreting the emerging picture—a Biden presidency paired with a Republican Senate—as a scenario where radical policy shifts would be unlikely.

Asia's stock markets had climbed 2 percent overnight, reaching their highest point since February 2018. Japan's Nikkei rose 1.7 percent to a nine-month peak. South Korea gained 2.4 percent. Chinese blue chips added 1.3 percent, buoyed by the prospect that a Biden administration might ease the tariff pressures that had defined the Trump years. In Europe, the FTSEurofirst index was up 0.8 percent as the Bank of England's stimulus announcement rippled through trading floors. Italy's five-year bond yields dipped below zero—a sign of how aggressively investors were repositioning.

The logic driving these moves was straightforward: a divided Congress meant less chance of aggressive new regulation, fewer tax increases on corporations, and a reduced likelihood of massive government spending programs that would flood the bond market with new supply. Michele Pedroni, a fund manager at Decalia Asset Management in Geneva, captured the sentiment plainly. The threat of heavy-handed regulation and tax hikes had receded, she said, and investors who had pulled back from risk ahead of the election would now feel compelled to jump back in. Tech stocks—Amazon, Facebook, Google—surged between 6 and 8 percent on this logic.

The bond market's reaction was even more dramatic. The 10-year Treasury yield fell to 0.74 percent, down from a five-month high of 0.93 percent the day before. That 11 basis point drop in a single day was the largest move since the panic selling of March, when the coronavirus first crashed through financial markets. The message was clear: if the federal government would not be spending heavily on stimulus and infrastructure, then the Federal Reserve would likely have to step in with its own tools—quantitative easing, asset purchases, liquidity injections. Central banks globally would become the backstop.

Currency markets reflected the same shift. The dollar, which had swung wildly overnight, settled back. It had peaked at 104.32 yen but retreated to 104.38. The euro held steady at $1.1734. Sterling, which had its own troubles—Brexit negotiations remained stalled, and reports suggested the Bank of England was even considering negative interest rates—recovered to $1.3023 after dipping lower. Gold, benefiting from the expectation of continued monetary easing, sat at $1,909 an ounce.

Oil prices told a different story. Crude had jumped 4 percent on Wednesday as traders bet that a divided government would struggle to pass environmental legislation that might have favored renewable energy over fossil fuels. But by Thursday, profit-taking had set in. U.S. crude slipped to $38.37 a barrel, and Brent fell 80 cents to $40.43. The initial euphoria about regulatory gridlock had already begun to fade.

Randal Jenneke, a portfolio manager at T. Rowe Price, described the emerging political outcome as a "goldilocks scenario" for financial markets—no radical policy swings, but plenty of central bank support to keep the system liquid. Yet beneath that calm assessment lay an uncomfortable truth: if Congress would not act, the burden of supporting the economy would fall almost entirely on the Federal Reserve and other central banks already stretched thin from pandemic-era stimulus. The rally was real, but it rested on the assumption that monetary policy alone could carry the weight that fiscal policy would not.

The big bad wolf of regulation and taxes is further away from the door and many who have de-risked into the event will be forced to re-risk.

Why did markets rally on news of a divided Congress? Isn't gridlock usually bad for business?

Model

Not in this case. Investors were terrified of what a unified Democratic government might do—aggressive regulation, higher corporate taxes, massive spending programs. A split Congress meant none of that would happen easily.

Inventor

So they were betting against change?

Model

Exactly. They were betting that the status quo would hold. And that the Federal Reserve would keep the money flowing to compensate for whatever the government wouldn't spend.

Inventor

But doesn't that put enormous pressure on central banks?

Model

It does. The Bank of England had just announced 150 billion pounds in new stimulus. The Fed would likely follow. Central banks were becoming the only game in town.

Inventor

What about the bond market's reaction? That 11 basis point drop seems extreme.

Model

It was the biggest single-day move since March's pandemic panic. Investors were suddenly convinced the government wouldn't be issuing massive amounts of new debt, so bond prices shot up and yields fell.

Inventor

And the tech stocks surging 6 to 8 percent—was that the same logic?

Model

Partly. But also the belief that a Biden administration would be less hostile to big tech than Trump had been. Less antitrust pressure, less regulatory scrutiny.

Inventor

So the market was essentially saying: we prefer a weak government and strong central banks?

Model

In a way, yes. Or at least: we prefer predictability and liquidity over the risk of radical change.
