Equity movement of a branch

If your question is about blocked funds that cannot be repatriated because of country Central Bank foreign exchange restrictions, this is an old problem that applies equally to a subsidiary or to a branch. Solutions can be divided into those where the asset remains in the sub/branch but is redeployed in a way that hedges/protects from devaluation (usually at high cost) vs. those that remove the asset from the sub/branch. Removal is a function of the exact legal restrictions imposed and the availability of parallel exchange rate asset swap transactions that typically fall into a grey area of local law (and also entail costs).
