How Does the US Presidential Inauguration Affect the Markets?

The United States presidential inauguration signals the start of a new administration and policy direction. While its ceremonial aspects dominate the headlines, this event also has significant implications for financial markets. Here’s how the transition of power can influence market behavior and what traders should watch for during this critical period.

Market reactions to election results

The market’s reaction to the inauguration begins months earlier, during the election cycle. Stock indices, commodities, and currencies often reflect investor sentiment about potential winners and their policies. By the time Inauguration Day arrives in January, much of the market’s immediate reaction to the election results has already occurred.

After Donald Trump’s unexpected victory in November 2016, markets experienced a significant rally, dubbed the “Trump bump.” This rally extended into the weeks following his inauguration on January 20, 2017. Investors reacted positively to his pro-business promises, which included corporate tax cuts, deregulation, and infrastructure spending. 

For example, the S&P 500 gained over 6% between Election Day and Inauguration Day. Financial stocks surged, with the S&P Financials Index jumping 20% during the same period, driven by expectations of deregulation.

Policy anticipation and sectors in focus

Presidential policy agendas can significantly impact specific sectors. For example, during Trump’s 2017 inauguration, the different sectors experienced the following:

• Energy. Trump’s pledge to roll back environmental regulations and withdraw from the Paris Agreement buoyed fossil fuel companies like ExxonMobil and Chevron. Solar and wind energy companies faced headwinds due to Trump’s focus on fossil fuels and reduced federal support for clean energy initiatives.
• Financials. Promises to repeal parts of the Dodd-Frank Act and loosen banking regulations led to significant gains for major banks like JPMorgan Chase and Goldman Sachs.
• Industrials and materials. The prospect of large-scale infrastructure spending fueled a rally in construction-related stocks like Caterpillar and steel manufacturers like U.S. Steel.
• Technology. Tech giants like Amazon and Google faced scrutiny over trade policies and Trump’s rhetoric on immigration, which could impact their global workforce.

Investors often reposition their portfolios based on the perceived winners and losers of the new administration’s agenda.

Historical patterns and market volatility

Historical trends suggest that markets generally prefer certainty. The inauguration can reduce uncertainty as the president formally takes office, signaling the transition to governance from campaigning. However, markets can remain volatile if the new administration faces significant controversy or policy uncertainty.

For instance, Trump’s inauguration was accompanied by heightened market volatility, driven by his unconventional communication style and unpredictability. While markets initially rallied, they remained on edge due to concerns about Trump’s foreign policy, including tensions with China and plans to renegotiate trade agreements like NAFTA, as well as policy implementation uncertainty.

Fiscal and monetary policy expectations

Presidential inaugurations often coincide with expectations of fiscal stimulus or austerity, depending on the administration’s economic philosophy. Markets closely watch for signals on:

• Spending plans. Infrastructure projects and economic stimulus packages often lead to rallies in construction and industrial stocks.
• Tax policies. Proposed tax hikes or cuts can shift capital flows, affecting both equities and bonds.

In 2017, Trump’s inauguration also influenced currency and bond markets. Following Trump’s victory, USD strengthened sharply as investors anticipated higher growth and inflation, spurred by proposed fiscal stimulus. However, this trend moderated as Trump’s protectionist rhetoric raised concerns about trade wars.

At the same time, yields on US Treasury bonds rose sharply in the post-election period, with the 10-year yield climbing from around 1.8% to over 2.5% by Inauguration Day. This reflected expectations of higher borrowing and inflation under Trump’s policies.

The global perspective

Given the US economy’s role in global markets, presidential inaugurations also affect international investors. A new administration’s stance on trade, foreign policy, and global cooperation can ripple through currency markets, emerging economies, and commodities.

Trump’s “America First” approach resonated globally during his first presidential term. Stocks and currencies in emerging markets faced headwinds as Trump signaled a tougher stance on trade deals like NAFTA and imposed tariffs on countries like China. The Mexican peso, for instance, dropped significantly in response to Trump’s trade threats.

Protectionist policies also initially created uncertainty for commodities like copper, used in infrastructure, which later stabilized as Trump clarified his spending priorities.

Key takeaways for traders

Trump’s focus on tax cuts and deregulation during his inaugural address reinforced market confidence, but subsequent political battles (e.g., over healthcare reform) highlighted the risks of overestimating policy implementation speed.

Financials, industrials, and energy were clear winners under Trump’s agenda, while sectors like healthcare faced headwinds from policy uncertainty.

While US markets thrived, Trump’s policies created volatility for global markets, particularly those heavily reliant on trade with the US.

As history shows, the impact of an inauguration extends far beyond the ceremony, offering opportunities and challenges for markets worldwide.
