Introduction: The 2025 Stock Market Roller Coaster
Quite accidentally, our last discussion about the stock market timing was spot on. In early 2025, the market capped off a multi-year climb, only to plunge into one of the most volatile periods in recent history. At its lowest, the market lost about 20% of its value, only to bounce back near previous highs by the time of writing.
While stock market volatility often defies easy explanation, this time the culprit seems clear: tariffs. These government-imposed taxes on imports have roiled markets, rattled businesses, and left investors wondering what comes next.
The big questions on everyone’s mind include:
- Can the president really impose tariffs as high as 145% on imports from major suppliers?
- Will these tariffs actually be implemented?
- What is the rationale behind tariffs — aren’t free trade and low prices better for everyone?
- What are the long-term economic and market consequences under varying tariff scenarios?
While the final outcomes remain uncertain, the effects are already visible: businesses are adjusting, currencies and interest rates are shifting, and investors are recalibrating their strategies.
What Is a Tariff? The Basics
At its core, a tariff is a tax levied by a government on goods imported into the country. This tax is paid by the importer — whether that’s a large corporation like Amazon or a small business importing products directly.
However, the ultimate payer of tariffs is the consumer. When importers face higher costs due to tariffs, they typically pass those costs on through higher retail prices. For example, if you order an e-bike from overseas, tariffs on that product will increase its price.
Tariffs also impact companies directly. Construction projects, for instance, rely on imported steel, copper, lumber, and other materials. Tariffs on these inputs raise construction costs, which in turn increase housing prices.
In essence, tariffs function like a broad-based sales tax, increasing prices and reducing consumer purchasing power. While the government collects revenue from tariffs, this usually comes at the cost of slowing economic activity.
The Role of Taxes in a Functioning Economy
Every government requires tax revenue to fund public services, infrastructure, defense, and more. Ideally, taxes should be as low as possible while still providing sufficient funds. They should also be fair, predictable, and structured to incentivize productivity and investment.
The current tariff regime, however, has been anything but predictable or fair. The administration has proposed wildly fluctuating and extremely high tariff rates, often changing on short notice. This unpredictability creates uncertainty for businesses and consumers alike.
Is There a Positive Side to Tariffs?
Tariffs are sometimes used to protect domestic industries from foreign competition. For example, imposing a tariff on imported Hondas could give an advantage to domestic automakers like General Motors (GM), potentially preserving jobs and encouraging local manufacturing.
This protectionist approach can be strategic — such as safeguarding national defense industries — or it can be driven by political or special interest motives. For instance, tariffs on imported steel may protect domestic steel companies but raise costs for manufacturers and consumers.
Interestingly, tariff policies have been employed by both major political parties. For example, tariffs on imported solar panel components were introduced to protect domestic producers, despite the fact that solar panels provide cheap, clean energy that benefits the entire economy.
Can Tariffs Create More Jobs?
Let’s revisit the hypothetical $5,000 tariff on Hondas. Such a high tariff would make Hondas more expensive, pushing some buyers toward GM vehicles. GM might then hire more workers and invest in new factories to meet increased demand.
While this sounds beneficial, the broader economic picture is more complex:
- Consumers pay more for cars, reducing their disposable income.
- Higher vehicle prices increase costs for companies like Amazon, which raises prices on goods.
- Other industries face higher input costs, slowing innovation and growth.
- With less competition, domestic companies may become complacent, reducing efficiency and innovation.
Most economists agree tariffs generally reduce overall employment and economic growth, except in specific cases like food security or critical defense industries.
Why Are Tariffs Being Used So Aggressively in 2025?
The aggressive tariff strategy has puzzled many. The administration appears to believe tariffs will boost domestic wealth by protecting industries and jobs. However, this view overlooks the broader inefficiencies and costs tariffs impose on the economy.
The stock market’s reaction — falling when tariffs rise and rallying when they ease — reflects investor skepticism about the economic wisdom of tariffs.
Some theories explain the tariff strategy as:
- Unfettered power: The president can impose tariffs unilaterally under emergency powers, bypassing Congress temporarily.
- Negotiating leverage: Tariffs pressure trading partners to make concessions.
- Control over domestic companies: Disrupting supply chains can exert control over industries.
This concentration of power raises constitutional concerns about the balance of government branches.
Historical Context: How Big Are Today’s Tariffs?
Even without the extreme 145% tariff proposals, current tariffs are significantly higher than in recent decades. The U.S. economy has thrived for decades on relatively low tariffs and free trade.
Below is a simplified historical overview of U.S. tariff rates over the last 175 years:
| Period | Average Tariff Rate | Economic Context |
|---|---|---|
| Mid 1800s | ~40% | High tariffs to protect budding industries |
| Post WW2 to 1980s | ~5-10% | Era of growing free trade agreements |
| 1990s to 2020 | ~1-5% | Low tariffs supporting globalization |
| 2025 (Current) | ~15-20% (varies by product) | Significant increase due to trade tensions |
This sharp rise in tariffs is a major departure from decades of trade policy.
Why Haven’t Prices Soared Yet?
The U.S. economy operates like a giant cargo ship with large inventories. Even as tariffs were announced, importers stocked up on goods to avoid higher costs, delaying the impact on retail prices.
The Freightwaves Ocean Shipping Index (OSI) shows a significant drop in imports following tariff announcements, indicating stockpiling has ended and fewer goods are arriving.
As existing inventories run out, shortages and price increases are expected in the coming months, especially for essential goods like tools and machinery. Non-essential items may see less impact.
Scenarios for the Future: How Will Tariffs Play Out?
The phrase “This too shall pass” is apt for the current situation. While uncertainty remains, here are two broad scenarios:
Scenario 1: High Tariffs Persist
- Inflation could more than double in 2025, adding roughly 4% to consumer prices (imports are ~25% of spending, tariffs up ~16%, so 0.25 × 0.16 = 0.04).
- Companies reliant on cheap imports may shut down or relocate.
- Some domestic manufacturing will increase, especially in steel and auto parts, but consumer goods like shoes and electronics will become more expensive.
- Demand for low-wage manufacturing jobs may rise, but wage gains could be offset by higher living costs and eventual automation.
- Retaliatory tariffs from other countries will hurt U.S. exporters, reducing their revenues.
- Government tariff revenue could increase by about $640 billion annually (~15% of the federal budget), but lost economic activity may reduce income tax revenue by an unknown, possibly larger amount.
Scenario 2: Tariffs Are a Negotiation Tactic and Are Reduced
- The stock market would likely rally strongly on relief.
- Companies would resume normal planning and hiring.
- The economy would lose some activity but recover over time.
- Trade deals might improve market access for U.S. exporters.
- The best strategy to “win” the tariff game is to avoid playing it.
The Broader Lesson: Free Trade Benefits Everyone
The U.S. economy’s strength comes from its large population, open borders, and relatively free trade. When countries collaborate and exchange goods, services, and ideas freely, everyone benefits.
Protectionism and tariffs often create winners and losers, but the net effect is usually a drag on overall prosperity.
Market Reactions and Investor Sentiment
When tariffs are announced or increased, stock prices tend to fall as investors anticipate lower corporate profits. When tariffs are paused or reduced, markets rally.
This pattern reflects the market’s view that tariffs impose real costs on businesses and consumers.
Case Study: Tesla and Canadian Tariffs
Canada recently imposed a 25% tariff on Tesla vehicles imported from the U.S., causing Tesla’s Canadian sales to plummet almost overnight. This example illustrates how retaliatory tariffs can directly harm U.S. exporters.
Inflation and Your Personal Finances
Inflation erodes the purchasing power of your money. If tariffs cause prices to rise, your cost of living increases, impacting your savings, investments, and loan repayments.
For example, if inflation rises from 3% to 6%, the real value of your fixed income or savings declines faster, making it harder to maintain your lifestyle without increasing income or investment returns.
How to Protect Yourself Financially During Tariff Uncertainty
- Diversify investments: Spread your portfolio across sectors and geographies to reduce risk.
- Focus on inflation-beating assets: Equities, real estate, and commodities often outpace inflation over the long term.
- Keep an emergency fund: Higher inflation and economic uncertainty make liquidity crucial.
- Monitor loan interest rates: Inflation can reduce the real cost of fixed-rate loans, but variable rates may rise.
- Use tools like LoanVsFD calculators: Evaluate how inflation and interest rates affect your loans and investments.
Understanding Media Bias and Financial News
In today’s media landscape, headlines often prioritize attention over accuracy. Political bias, sensationalism, and fear-mongering can distort financial news.
It’s important to:
- Ignore noise and focus on your personal financial goals.
- Become a subject matter expert in areas important to you.
- Read original sources and data rather than relying solely on headlines.
Final Thoughts: Staying Calm and Informed
The current tariff-driven volatility is unsettling but not unprecedented. History shows that markets and economies adapt over time.
Staying disciplined, informed, and focused on long-term goals is the best way to navigate uncertainty.
As of now, many investors remain optimistic that a resolution will restore more stable trade relations and economic growth.
