Destabilization is the process of making something — especially a government or an economy — less successful, less powerful, or less able to control events. The thing still stands, but it wobbles: leaders lose their grip, markets swing wildly, people stop trusting the system. You hear it in news and political talk: the destabilization of a government, of a region, of the economy. People also stretch it to markets, currencies, even a sports team after a shock, but the home of the word is public life, not a wobbly chair. This spelling with z is the usual American one; British writing often has destabilisation. The noun names the process; the doing is destabilize.
