Let’s bust a myth straight out of the blocks: the widely held belief that emerging market local bonds are sensitive to US long rates. It’s groundless and unfounded.
Sure, there are times (like now) when the performance of EM local bonds is negative US rates are rising, and vice versa, but the correlation is by no means a sign of solid, stable causation – a pity that, as it would make my job a lot easier. But as Algernon says in Oscar Wilde’s play The Importance of Being Earnest: “the truth is rarely pure and never simple.”
The adherents of the higher-US-rates-are-bad-for-EM-bonds theory claim that, on average, rational investors would allocate their money where interest rates are higher and, in addition, will tend to divest from the borrowers that are supposed to suffer from higher US rates. Putting that in the context of EM debt, investors would sell EM debt because higher rates would make EM issuers less creditworthy, and they would then use the proceeds to buy US Treasuries that are safer and more lucrative.
Let’s dispel that fallacy point by point:
But what if the above rationale is just EM propaganda, a sort of biased post-truth written by people who are judges of their own cause? Well, in that case, we can turn to the facts:
In other words, anyone who was lucky and/or smart enough to predict US rate moves correctly over the past 20 years, was unable to generate any profit from taking the opposite stance on EM local bonds. The latter statement might sound provoking and unsettling, but it is the reality.
As my colleagues and I have often advocated (see here and here ), what matters for EM investors is not if US rates are high but where the US dollar is heading to. Of course, higher US rates can put upward pressure on the US dollar, but let’s remember that EM local rates are currently at their widest level compared to US rates. Algernon was right, the truth is rarely pure and never simple.
i. Primary budget balance = current government spending less current income from taxes, excluding interest paid on government debt. A primary surplus allows a country to reduce the present value of its debt.
ii. Prospective real rates are the interest rates that an investor expects to receive after adjusting for the prospective inflation.
iii. rospective real growth is the expected economic growth of a country, usually as expressed by the gross domestic product, after adjusting for the prospective inflation.
iv. The net international investment position is the difference between the external financial assets and liabilities of a country.
v. We computed the regression using weekly data to have a lot of observations, but we did also do the maths on monthly return data and the correlation remains extremely low.
