Example

In its 2022 Integrated Review Refresh, the United Kingdom justified renewing the Dreadnought-class submarine programme partly as an "insurance" against unforeseeable deterioration in the strategic environment over the coming decades.

In international relations, the Insurance Doctrine describes policy choices made primarily to guard against low-probability but high-impact risks, rather than to maximize expected gains. The logic mirrors commercial insurance: a state accepts ongoing costs (defense spending, redundant supply chains, diversified alliances) in exchange for protection if a worst-case scenario materializes.

The concept is most often invoked in three contexts:

Nuclear strategy. Analysts describe second-strike forces, ballistic-missile submarines, and dispersed warhead stockpiles as "insurance" against a disarming first strike or against the failure of deterrence. The United States, Russia, France, and the United Kingdom have all justified continuous-at-sea deterrence patrols in these terms.
Hedging behavior. Middle powers such as Vietnam, Singapore, and India are frequently described as pursuing insurance strategies — deepening ties with the United States while preserving working relationships with China — so that no single great-power outcome leaves them exposed.
Economic security. Since the COVID-19 pandemic and the 2022 disruptions following Russia's invasion of Ukraine, "insurance" framing has spread to semiconductor stockpiling, energy diversification (notably the EU's pivot away from Russian gas), and "friend-shoring" of critical mineral supply chains.

Critics note two recurring problems. First, insurance is expensive, and the premium is paid regardless of whether the risk materializes — making it politically vulnerable during budget cycles. Second, insurance policies can be self-defeating: a state that visibly hedges may signal distrust to a partner or provoke the very threat it sought to insure against, a dynamic close to the classic security dilemma.

The term is descriptive rather than legal; it appears in policy white papers and academic analysis (e.g., work by Evan Medeiros on hedging) rather than in treaty text.

Frequently asked questions

How is the Insurance Doctrine different from deterrence?

Deterrence aims to prevent an adversary from acting by threatening costs; insurance aims to limit damage if prevention fails. A second-strike force does both, which is why it is often cited as the archetypal insurance capability.

Is 'Insurance Doctrine' an official government term?

No. It is an analytical label used by scholars and journalists. Governments rarely codify it, though documents like U.S. Nuclear Posture Reviews and the UK Integrated Review use insurance-style language.

How does it relate to hedging?

Hedging is the broader strategy of avoiding firm commitments; insurance is one motivation for hedging, specifically focused on protecting against worst-case outcomes rather than capturing upside from multiple partners.
