[#07B] When Policy Arrives Without Warning
We have a new, very public example of the world we’re ageing into, and it illustrates very well why old financial planning approaches will fail you if you rely on them.
Trump’s Tehran-Trading Tariff
Last month, the President of the United States announced a new tariff.
Not via a press conference.
Not through the State Department.
Not following consultation with trading partners, Congress, or Think Tanks.
It appeared instead as a short post on Truth Social, the social media platform owned by the President himself.
The post was blunt: any country caught doing business with a particular state that had fallen out of favour with the U.S. would now face punitive trade consequences.
The point here is not whether the tariff was justified. Nor is it about one individual. The point is what it reveals about the world you are ageing into.
It took almost no time at all for markets to react; within a week the Dow had shed USD$1 trillion.
Governments reacted too -- China promised retaliation, and the EU suspended negotiations which had been ongoing since Trump’s previously announced ‘Liberation Day’ tariffs.
Established media outlets were treating this single ‘Truth Post’ as de facto international economic policy.
Policy without process
Global economic policy for your parents and mine followed a very different and very familiar process.
Signals were telegraphed.
Allies were briefed.
Institutions acted as buffers.
Change, while sometimes disruptive, arrived with warning.
That process no longer applies. It was policy via Tweet.
Markets weren’t so much reacting to the tariff itself, but the realisation that consequential decisions can now arrive suddenly, personally, and unilaterally — without the guardrails many investors still assume exist.
That is not a temporary aberration. It is a structural shift.
Risk isn’t revealed during good times
We might be tempted to write this off as messy politics, and – no argument, it most certainly is. But there’s another dimension to this and it has deeper implications. You see, the problem isn’t politics, it’s fragility. It reveals how modern financial lives are more exposed than at any point in history.
Globally diversified portfolios are a source of huge opportunity but they also carry this shock-baggage, where an abrupt event in one jurisdiction ripples immediately through markets everywhere.
The internet has expanded the market reach of even the smallest business and as a result they now rely on international supply chains like never before. Geopolitics brings a new dimension of complexity to this already dynamic sector.
Retirement incomes, once anchored to local assets and predictable drawdown patterns, are increasingly tied to capital markets and financial instruments whose edges are blurred.
And currencies, commodities, and interest rates — once treated as separate variables — now move together across borders, meaning stress in one part of the system rarely stays contained.
Risk isn’t revealed during good times, it shows up when conditions change. That’s when it becomes clear whether your planning has depth to it.
As the saying goes, ‘when the tide goes out you see who’s been swimming naked.’
This is not an argument for retreat
It would be easy to read this and conclude that the solution is to step off the global stage — to invest locally, simplify exposures, and withdraw into the familiar.
An understandable reaction, but it doesn’t solve the problem, and here’s why ...
Parochial portfolios do not eliminate risk; they concentrate it. This ties financial outcomes more tightly to a single economy, a single political system, and a narrower set of assumptions about growth, stability, and policy competence.
The lesson here isn’t that global exposure is dangerous. It’s exposure without resilience: no choices, no buffer, and no disciplined process for reassessing conditions and advancing options as the world changes.
In a world where shocks are more frequent and they travel faster and further, resilience doesn’t come from shrinking the map. It comes from having a robust process that dispassionately assesses the situation and canvasses options to advance your cause. This absorbs the stress and opens up opportunities while minimising the scope for irreversible mistakes.
That distinction — between reactivity and proactivity — is one most traditional retirement plans never make.
Why this matters more as you get older
If you’re in your 50s or 60s, this matters in a very specific way. You are no longer building optionality — you are increasingly relying on it.
Your parents planned their financial lives in a world where:
retirement was shorter,
markets were more local,
policy changes were slower, and
volatility, while present, was episodic.
You are ageing into a world where:
careers last longer but fracture more often,
retirements stretch across multiple decades,
capital must do more work for longer, and
shocks arrive without warning.
Planning for that world using yesterday’s assumptions isn’t conservative. It’s reckless.
Volatility isn’t the risk. Surprise is.
Most traditional retirement plans already acknowledge volatility — at least in theory.
They stress-test returns.
They model averages.
They include disclaimers.
What they rarely account for is surprise:
the speed of change,
the compression of cause and effect,
the removal of institutional buffers.
A tariff announced after months of stress-testing, consultation and negotiation is one thing. A tariff announced instantly, personally, and globally via social media is something else entirely.
Same policy lever. Different world.
This is why the old maps fail
This essay sits outside the main series for a reason.
It isn’t about optimisation.
It isn’t about clever strategies.
It isn’t even about Trump.
It’s about recognising that the terrain has changed.
When the world becomes more nonlinear, more politicised, and more abrupt, planning must shift from prediction to resilience — from neat projections to systems that can absorb shocks without breaking.
That is the through-line of this entire project.
And it’s why the financial life you’re ageing into cannot be planned the way your parents planned theirs — even if their plan “worked”.
