Despite a year defined by escalating geopolitical tensions – including the ongoing war in Ukraine, the conflict in the Middle East, and renewed trade disputes – global stock markets have demonstrated surprising resilience. Analysts widely predicted critically important downturns in response to events such as former President Trump’s proposed tariffs and rising national debt, but those forecasts have largely failed to materialize. This article examines the disconnect between these considerable headwinds and the unexpectedly strong performance of major indices, including the Nasdaq, Nikkei, and France’s CAC, as of late 2025.
Few predicted the resilience of global equity markets given the confluence of geopolitical and economic headwinds experienced this year. Had the question been posed at the start of 2025 – what would happen to global and French stock indices if former President Trump imposed tariffs of up to 100%, the war in Ukraine continued, national debt reached record levels, a conflict erupted between Israel and Iran, long-term interest rates surged in Japan, and France lacked a coherent economic policy? – the consensus expectation would have been a downturn, particularly for the CAC.
Yet, despite a year marked by a multiplying series of significant shocks – including those mentioned above – 2025 is on track to be remembered as a period of remarkably strong performance for stock markets worldwide. The Nasdaq has risen 17%, while the Nikkei has seen gains of 22%. Even the CAC has posted a 9% increase, defying expectations. This performance underscores the complex dynamics at play in global financial markets and the ability of equities to absorb substantial risk.
Looking back at the last twelve months, the sheer number and magnitude of these challenges to financial markets are striking. The strength of these indices, despite these headwinds, suggests a disconnect between geopolitical events and investor sentiment. The data highlights the ongoing debate among economists regarding the factors driving market performance in the current environment.
The unexpected strength of global indices comes as companies continue to deliver solid results, as evidenced by the performance of firms listed on the CAC, despite the political uncertainty. The impact of tariffs, alongside other global events, has not yet fully translated into the widespread market declines many anticipated.
