A novel capital control proposal

New book

By Pablo Bortz (Guest blogger)*

After the breakdown of the Bretton Woods regime and the subsequent deregulation in capital flows around the globe, the movement of financial assets and liabilities has increased several times faster than trade and GDP growth. While still mainly concentrated between advanced countries, financial flows to emerging and developing economies (EDEs) have been rising at an exponential rate, particularly in the last two decades. However, public external debt (as per cent of GDP) has been on a downward trend in the 2000s (though the trend has been slightly reversed since the 2008 crisis), with a larger proportion being denominated in domestic currency, but attracting more non-resident private investors (Arslanalp and Tsuda 2014). The other big story of the last fifteen years, notwithstanding, is quite different: private external debt has been on a marked rise. As Akyüz (2014) reviews, the share of private debt denominated in a foreign currency has increased sharply, and that is not the only concerning feature observed in the data. Avdjiev et al (2014) notice the importance of private non-bank lenders in in the external financing of many emerging countries, and the role of overseas affiliates of EDEs corporations established in off-shore financial centers, rendering its recording more difficult. And though cross-border bank lending still represents the larger share of total external borrowing, there has been a fast increase in the issuance of debt securities by the private non-banking sector of EDEs and its off-shore affiliates (Butzen et al 2014), a more volatile kind of flow, together with portfolios investment.

Far too numerous crises in emerging (and some advanced) economies have been preceded by explosions in private foreign borrowing, starting from the 1970s in Latin America, and continuing during the 1990s also in Latin America and (above all) South-East Asia, as told by Palma (2001). And in the last decade we have seen the burst of the Eurozone, also triggered by sharp increases in foreign indebtedness (Storm and Naastepad 2016). Financial fragility is not the sole cause of these crises and the lasting damage they leave behind. As I mention in my recent book (Bortz 2016), private foreign borrowing turn the odds of wage bargaining against labor, lowering the wage share and putting aggregate demand in a more fragile standing. Motives for this result abound: the impact of higher indebtedness and debt servicing on firms’ balance sheet (costs that firms try to pass on consumers); the fact that mounting foreign borrowing and capital inflows are matched by financial deregulation that stimulates alternative outlays other than capacity-building investment; and because they are tied to the rise of sectors such as the FIRE sector (financial, insurance and real state) lowering aggregate productivity, among other reasons. Jayadev (2005), Stockhammer (2009) and Furceri and Loungani (2015) all find empirical support for these hypothesis.

After amending in 1997 its Articles of Agreement, requiring member countries to liberalize their capital account, the IMF has joined the large chorus of voices calling for capital controls, although in the most muted way possible (IMF 2012, p. 2). Calls for restoring capital controls rise across the economic spectrum, from authors with a more orthodox point of view such as Hélène Rey (2013) to non-mainstream economists such as Vernengo and Rochon (2000), Epstein (2005), Bibow (2011), Gallagher (2014), Grabel (2015), among many others. International institutions such as UNCTAD have been at the frontier of the debate (UNCTAD 2001, 2014), and even recent research by IMF staff has dwelled into the topic (Ostry et al 2011, Canuto and Ghosh 2013).

It is within this context that I suggest a novel proposal for consideration, the implementation of which should obviously reflect the particularities of each economy. What I propose is a refundable tax on foreign private borrowing, that discourages speculative borrowing in favor of productive investment. The basic idea is simple: companies should pay a tax when they borrow abroad, either through banks, issuing debt securities, when they borrow from their home companies or off-shore affiliates. That tax would be reimbursed if firms can prove that these credits have been used to fund productive investment.

This proposal is particularly fit to counter lending and borrowing between affiliates, a common channel to facilitate transfers of funds in times of need with disregard of the economic conditions of the country. For instance, it was one of the major channels by which affiliates in EDEs transferred large amounts of foreign currency to their home companies in developed countries during the 2008 financial crisis and the Eurozone crisis.

Implementation aspects raise a couple of questions of which I am fully aware. First, there is the need to define precisely what “productive investment” stands for: does it include software licenses and patents? Second, the State would require the administrative capabilities to verify the companies’ claims on the nature of their borrowing, while assuring that banking funds are indeed available in the domestic market (perhaps through public banks and/or development banks). However, the main intention of this proposal is to pass the burden of the proof to firms rather than the State. A further issue to be discussed concerns cross-border bank lending. The scheme should discriminate in favor of foreign lending for investment purposes, though its implementation would involved more thoughts and efforts in its design.

This proposal should not be thought of as a substitute for more specifically-FDI-oriented policies. There may well be different and valid reasons for countries to discourage FDI, and this measure does not stand in its way. It is not incompatible with other typical capital control measures such as unremunerated reserve deposits on financial investments or measures that restrict capital flights. This proposal is just one instrument, perhaps a modest one, to try to curb speculative borrowing by firms, particularly in foreign currency, an ever-increasing practice which offers negligible benefits and which adds to headwinds when foreign reserves are needed the most (Chui et al 2014).

A few brief comments on Brexit and the postmortem of the European Union

Another end of the world is possible
There will be a lot of postmortems for the European Union (EU) after Brexit. Many will suggest that this was a victory against the neoliberal policies of the European Union. See, for example, the first three paragraphs of Paul Mason's column here. And it is true, large contingents of working class people, that have suffered with 'free-market' economics, voted for leaving the union. The union, rightly or wrongly, has been seen as undemocratic and responsible for the economics woes of Europe.

The problem is that while it is true that the EU leaders have been part of the problem and have pursued the neoliberal policies within the framework of the union, sometimes with treaties like the Fiscal Compact, it is far from clear that Brexit and the possible demise of the union, if the fever spreads to France, Germany and other countries with their populations demanding their own referenda, will lead to the abandonment of neoliberal policies.

A brief note on Venezuela and the turn to the right in Latin America

So besides the coup in Brazil (which was all but confirmed by the last revelations, if you had any doubts), and the electoral victory of Macri in Argentina, the crisis in Venezuela is reaching a critical level, and it would not be surprising if the Maduro administration is recalled, even though right now the referendum is not scheduled yet.

The economy in Venezuela has collapsed (GDP has fallen by about 14% or so in the last two years), inflation has accelerated (to three digit levels; 450% or so according to the IMF), there are shortages of essential goods, recurrent energy blackouts, and all of these aggravated by persistent violence. Contrary to what the press suggests, these events are not new or specific to left of center governments. Similar events occurred in the late 1980s, in the infamous Caracazo, when the fall in oil prices caused an external crisis, inflation, and food shortages, which eventually, after the announcement of a neoliberal economic package that included the i…
