The world is now closer to a full-fledged trade war than ever before. In early March 2025, US stock markets tumbled over concerns that President Donald Trump’s tariffs on Canada, Mexico, and China will lead to a wider trade war and hurt the economy. Having tracked global financial markets through decades of turbulence, it’s evident this moment could redefine global trade and investment. This article delves into the intricate dynamics of trade wars and their far-reaching impact on global financial markets.
What Is a Trade War?
A trade war starts when countries impose tariffs—taxes on imports—or restrictions to protect their economies, prompting retaliation. Trump’s 2025 tariffs hit Canada and Mexico with 25% duties and China with 10%, targeting over $1.3 trillion in US imports. Canada countered with $155 billion in levies, Mexico promised reprisals, and China vowed action at the WTO. The global nature of modern economies means that the ripple effects of such conflicts are felt far beyond the countries directly involved. It is therefore unsurprising that economists have warned that the 2025 trade war will send shockwaves across the global economy, disrupting trade flows and rattling financial markets.
Historical Context: The Smoot-Hawley Tariff Act
One of the most cited historical examples of trade wars is the Smoot-Hawley Tariff Act of 1930. This US law saw the US raise duties on 20,000 goods, triggering a global backlash that slashed trade by 66% in three years. The Dow Jones cratered, and the Great Depression deepened—a cautionary tale of how trade wars amplify economic pain. Today’s broader scope, hitting key partners, risks echoing that era, threatening stocks, forex, and the wider economy.
Lessons from the 2018-2019 Trade War
The 2018-2019 US-China trade war provides fresher insight. Trump’s tariffs on $380 billion of Chinese goods sparked a 5% S&P 500 drop on key announcement days, while the yuan fell 10%, softening export losses for Beijing. US GDP took a 0.2% hit, per the Tax Foundation, and consumer prices edged up 0.3%. Overall, the prolonged dispute resulted in fluctuating stock markets, volatile forex rates, and disruptions to global supply chains. Markets hated the uncertainty—volatility spiked, yet some traders thrived on forex swings. The lesson? Trade wars bruise growth but can also create opportunities for savvy traders.
Winners & Losers: How Might the 2025 Tariff War Impact the Markets?
Stocks: Trade wars create uncertainty, and financial markets generally react negatively to uncertainty. When tariffs are imposed, the immediate reaction is often a sell-off in equities, as investors fear the potential impact on global supply chains and corporate earnings. For instance, the tariffs announced by President Trump in 2025 led to a significant drop in major stock indices, reflecting investor concerns about the potential for a prolonged economic downturn.
Forex (USD vs CAD, CNY, EUR): The forex market is highly sensitive to trade tensions. Tariffs can lead to currency depreciation or appreciation depending on the perceived impact on the respective economies. In the case of the 2025 tariffs, the US dollar experienced fluctuations as investors weighed the potential effects on the American economy. Meanwhile, currencies of nations targeted by tariffs, such as the Canadian dollar, Chinese yuan, and euro, also saw increased volatility.
Gold: As a safe-haven asset, gold often benefits from increased uncertainty. During trade wars, investors may flock to gold as a hedge against market volatility and economic instability. The 2025 trade tensions saw a surge in gold prices as investors sought refuge from the turmoil.
Bitcoin: As a decentralized asset, Bitcoin can behave differently from traditional financial assets during trade wars. While Bitcoin’s price movement is influenced by a myriad of factors, heightened global tensions and economic uncertainty can drive interest and investment in cryptocurrencies.
What Does a Trade War Mean for Inflation and Growth?
Trade wars can have significant implications for inflation and economic growth. Tariffs fuel inflation by hiking import costs—Goldman Sachs estimates a 0.7% rise in US core inflation from 2025’s measures. Growth suffers too: Bloomberg Economics predicts a 16% GDP cut for Mexico and recession risks for Canada, reliant on trade for 70% of its economy. The 2018-2019 clash shaved 0.8% off global GDP. For online trading, this means tighter margins and slower gains—indices like the Nasdaq feel the pinch as costs climb.
Investor Sentiment and Market Psychology
Trade wars unsettle investors. The US Economic Policy Uncertainty Index soared in 2025, mirroring 2018’s tariff jitters. Markets crave stability—Nasdaq futures fell 2.35% post-announcement, only to pare losses as talks hinted at pauses. Psychology shifts fast: fear drives sell-offs, but hope of deals sparks rebounds, as seen with the MSCI China Index’s 36% recovery after 2019’s Phase One deal. Traders in forex and stocks must read these mood swings to stay ahead.
Long-Term Economic Consequences
Prolonged trade wars redraw economic maps. The 2018-2019 tariffs shifted US deficits to Vietnam, not China, showing trade reroutes rather than resolves. Today’s $900 billion tariff net could isolate the US if BRICS nations—Brazil, Russia, India, China, South Africa—counter with their own bloc tariffs, per Deutsche Bank’s George Saravelos. Supply chains fracture, costs linger, and global growth stalls—a tough landscape for financial markets long-term.
The Role of Central Banks and Interest Rates
Central banks play a critical role in mitigating the economic impacts of trade wars. However, currently central banks are up against unprecedented challenges. The Fed might delay 2025 rate cuts if inflation spikes, as Boston Fed’s Susan Collins hinted, tightening conditions for forex and indices trading. In 2018, the Fed held steady despite tariff pressures, but a deeper 2025 trade war could force hikes, squeezing growth. Canada’s central bank may cut rates below 2% if recession hits, per Russell Investments, flooding forex markets with liquidity. Interest rates become a pivot point for economic stability.
Global Risk: BRICS Tariffs and Potential U.S. Isolation
The rising influence of BRICS nations (Brazil, Russia, India, China, and South Africa) presents additional risks in the context of trade wars. The BRICS bloc looms large. If they unify tariffs against the US—say, 20% on American goods—the $680 billion US export market shrinks, per 2023 data. China’s trade pivot to the EU and Vietnam since 2016 (up 4% globally) shows adaptability; a BRICS push could accelerate this, isolating the US. Forex traders eye USD/CNY, while indices like the FTSE 100 brace for fallout as global risk climbs in this economy.
Opportunities Amid Volatility
While trade wars create challenges, they also present opportunities for strategic trading. In fact, volatility is a trader’s playground. The 2018 yuan drop handed forex profits to those shorting CNY/USD, and 2025’s USD/CAD surge offers similar shots. Gold’s uptick signals safe-haven plays, while oil’s jump suits commodity bets. Strategic trading—using real-time data and tight risk controls—turns chaos into gains across forex, stocks, and indices, rewarding those who adapt fast in online trading.
Navigating the Storm: Adaptability Is Key
In the face of trade wars and their complex implications, adaptability is essential. Investors must stay informed, remain flexible, and be prepared to adjust their strategies as new information emerges. In 2018, traders who pivoted to yuan weakness won big; today, agility across financial markets is non-negotiable. GVD Markets’ analytics sharpen this edge, helping traders weather trade war storms.

This is mostly due to higher costs and lowered consumption. In addition to creating inefficiency in the market, trade wars can also make industries less competitive.
The ripple effects of trade wars extend far beyond tariffs. UNCTAD estimates that 82% of redirected Chinese exports now benefit third-party nations, weakening domestic firms in both the U.S. and China. Meanwhile, unconventional monetary policies in advanced economies, like Fed rate hikes, amplify capital flight from emerging markets, worsening debt burdens. For long-term stability, policymakers must address fragmented global value chains and prioritize ESG criteria to build resilient economies. Investors should monitor sectors like digital assets and regional trade alliances to stay ahead in this turbulent landscape.”
Essentially the objective is to introduce a regressive consumption tax to offset tax cuts? Given how it appears tariffs are happening no matter what another country does, it’s hard to see how this is really a trade war. It’s just a suboptimal revenue raising tactic simply bolstered by the hope that it induces a reshoring of production.
