Timeline of the Invasion and Key Military Operations
The full-scale invasion began on 24 February 2022, when Russian forces launched a multi-front offensive from Belarus, the north, and the south toward Kyiv and major cities. The operation marked the largest military mobilization in Europe since World War II, involving an estimated 150,000 to 190,000 troops in the initial wave source.
By early March 2022, Russian advances stalled around Kyiv and Chernihiv, while the southern push toward Odesa and Mariupol intensified. The siege of Mariupol, which lasted until May 2022, became a symbol of urban warfare and drew international attention to civilian casualties and infrastructure destruction.
Economic Sanctions, Energy Markets, and Financial Impact
Western nations imposed sweeping sanctions on the Russian central bank, major banks, oligarchs, and key industries, freezing assets and restricting access to global capital markets. The U.S. and European Union also targeted technology exports, energy financing, and SWIFT access for selected institutions source.
Global energy prices spiked sharply in early 2022, with Brent crude rising above $120 per barrel and European natural gas futures hitting record highs. The European Union later phased in bans on Russian coal, oil, and refined products, reshaping trade flows and accelerating the shift toward alternative suppliers.
Humanitarian Toll, Displacement, and Reconstruction Costs
The United Nations reported millions of Ukrainians displaced internally and as refugees, with millions more affected by destroyed homes, hospitals, and critical infrastructure. The World Bank and other institutions estimated reconstruction needs in the hundreds of billions of dollars, covering housing, transport, energy, and industrial assets.
International aid pledges and reconstruction financing mechanisms were announced throughout 2022 and 2023, with the EU, U.S., and multilateral banks committing funds for immediate relief and long-term rebuilding. The scale of damage and ongoing security risks continue to shape investment decisions and insurance costs across the region.
