The Chinn-Ito index revised and updated to 2014 is now available here.

Figure 1 depicts the evolution of this measure of financial openness for three groups of countries:

To recap:

The Chinn-Ito index (KAOPEN) is an index measuring a country’s degree of capital account openness. The index was initially introduced in Chinn and Ito (Journal of Development Economics, 2006). KAOPEN is based on the binary dummy variables that codify the tabulation of restrictions on cross-border financial transactions reported in the IMF’s Annual Report on Exchange Arrangements and Exchange Restrictions (AREAER). This update is based on AREAER 2015, which contains the information on regulatory restrictions on cross-border financial transactions as of the end of 2014.

The CI index is a de jure measure, based on written (and self-reported) information (a characteristic it shares with most extant indicators). Moreover, it does not contain as much detailed information regarding the types of restrictions, nor does it differentiate between restrictions on inflows and outflows. On the other hand, it does cover a wider range of countries over a longer span than all others. (See Quinn, Schindler, and Toyoda (2011) for a discussion of the various measures.)

Capital openness measures are useful for assessing the international trilemma — the proposition that one cannot simultaneously pursue full financial openness, exchange rate stability, and monetary autonomy — as discussed here.

It’s of interest that financial openness has declined for emerging market economies (on the whole — this is a simple average); this result is not inconsistent with the increasing use of capital controls to stem capital inflows.[1]
