The markets are allergic to uncertainty, but they loathe cognitive dissonance even more. This morning’s headline from Jonathan Bowen — “LIVE: Bowen: US-Iran deal forces inescapable question of what the war was for” — is not just a diplomatic observation. It is a balance sheet adjustment. For twenty years, I have watched this city price in geopolitical risk, and today, the market is quietly marking down the returns on the single largest investment of this century: the post-9/11 security architecture.
The deal with Iran, if it holds, forces an audit. Not of dollars, but of credibility. The bond market, that great sceptic of government narratives, will now demand a return on the trillions spent in the Middle East since 2003. The yield on that investment? Questionable. The capital flight from the region? Already priced in. The real question, as Bowen puts it, is what the war was for. In financial terms, we are asking: what was the exit strategy for a trade that never closed?
Let me be blunt. The fiscal hawks in Whitehall have long argued that the Iraq and Afghanistan campaigns were a sunk cost. But sunk costs are only sunk if you admit the strategy failed. The Iran deal threatens to reveal that the entire interventionist model from the Bush era to the present was a leveraged bet that has now gone bust. The collateral was human life; the interest payments are paid in regional instability.
Central bankers, especially our own at Threadneedle Street, watch this with alarm. A de-escalation with Iran could open the taps for oil, but it also opens the door to a reassessment of sovereign risk. The US dollar, long the safe haven, may find itself under pressure as investors question the strategic coherence of American foreign policy. The gilt market, already rattled by domestic inflation, does not need another exogenous shock.
The bottom line is this: every war bond has a maturity date. This one has just been called. The question of ‘what the war was for’ is not rhetorical. It is a fundamental input for every portfolio manager, every pension fund, every government finance director. If the answer is ‘we do not know’, then the risk premium on global security just went up.
Bowen has done the news business a service by asking the question the Treasury would rather ignore. Now the markets will deliver their verdict. And they are rarely kind to incomplete accounting.
