The 1997–98 Asian financial crisis marked a turning point in the IMF’s previously negative views on the usefulness of capital account restrictions, culminating eventually in the publication of the Fund’s new Institutional View (IV) on the topic in 2012. The IV acknowledged that full capital account liberalization may not always be appropriate, accepted that new restrictions could at times have a useful role to play even in countries that had previously liberalized, and spelled out a specific set of circumstances under which the deploying of new restrictions could be justified as temporary measures in response to large capital flows. This paper documents the important role that empirical research, both by the profession at large as well as by the Fund’s own staff, played in supporting the first two components of the IV. It argues, however, that, empirical support is lacking with respect to the third component of the IV: the conditions under which the deployment of temporary capital account restrictions may be desirable. The conditions stipulated under the IV, which have the effect of considerably restricting the scope of circumstances in which the use of restrictions may be appropriate, are not fully justified by empirical evidence or recent experience and are best understood simply as a vestige of the institution’s pre-IV hostility to the use of restrictions.
