Abstract

The dollar is the clearest case on the board of a single factor pulling hard in
two directions at once. The US lands at #171 of 193 for currency (-4.10), yet
its 'reserve_currency' sub-factor is scored +5 near-term, -3 long-term (the
biggest near/long split in the dataset). That is not a hedge; it is the actual
shape of the privilege. The dollar is a large cushion today that is thinning
underneath, and the framework prices both halves.

What the reserve role buys, and for how long

Reserve-currency status is an "exorbitant privilege": the world holds dollars, so
the US borrows cheaply, runs deficits others could not, and exports some of its
own volatility. In the near term that cushion is intact, and it is the main reason
the US currency read is not far worse. But the cushion rests on trust in the
institutions behind the unit, and those are exactly what the US is being marked
down on elsewhere (statistical-agency interference, court pressure, tariff
volatility). A privilege that depends on institutional trust cannot outlast the
trust.

The numbers under it

The USD reserve share sits at 56.9% (Q3 2025 IMF COFER), a 31-year low; central
banks have been net sellers, and gold has overtaken Treasuries as the primary
reserve asset for some. None of that is collapse. It is slow erosion (the
exact profile that a near/long split captures and a single number would hide). The
long score of -3 says: assume the privilege keeps thinning as the institutions it
shielded are exposed.

Why the top of the currency board is small and boring

The currency leaders are Switzerland (6.31), Norway (5.84), and Singapore (5.59),
none of them reserve currencies, all of them small, open, institutionally deep,
and monetarily credible. That is the lesson the dollar's split reinforces: for the
near-term currency decision, what matters is the trustworthiness of the monetary
machinery, not the size or incumbency of the unit. The dollar's incumbency is a
real near-term asset; it is not a substitute for the institutions the other
leaders simply have.

Discussion: the privilege is the skew

The dollar split is also why the US carries a negative skew. The near-term
strength masks a downward tail: the more the institutions behind the dollar are
questioned, the faster the privilege can compress. Reserve status tends to erode
gradually and then suddenly; the framework cannot time the "suddenly", so it
encodes the direction (down) and keeps the near-term cushion at full weight rather
than pretending the privilege is already gone.

Limitations

• Reserve dynamics move slowly and are hard to forecast; the -3 long score is a
direction, not a date.
• The score rates the issuer's machinery and standing, not the dollar's exchange
rate, which can rise even as the structural privilege thins.
• A credible restoration of institutional independence would lift the long score
and narrow the gap to the leaders.

What would change this

Restored statistical-agency independence, a predictable trade posture, and fiscal
credibility would each slow the erosion and could pull the long-term reserve score
back up. Absent that, the honest read is a strong cushion now, a thinner one each
year. For the practical "what do I do with this" question, see
