The view held by Keynes, that there was a 'speculative appreciation' o
f sterling prior to its return to the gold standard, has been challeng
ed by Smith and Smith, who argue that expectations of return must have
weakened the currency. We demonstrate, first that the positive but de
creasing trend displayed in the exchange rate data is consistent with
a pattern of autoregressive convergence in fundamentals; and second th
at this continues to be true when there is a positive 'speculative' el
ement based on expectations of an early return. Hence the key features
of the data seem compatible with Keynes's views.
