Growth remains seemingly benign, most particularly in the US with the Atlanta Fed\u2019s GDPNow model indicating 3%YoY growth last quarter (see following chart). But, if there is a problem building for the American economy and indeed the world economy, and therefore for world stock markets, it is likely to be signalled by a surge in credit spreads.\r\n\r\nIn this respect, it has become much more important to monitor credit rather than monetary signals in modern economies because of the growth in financial disintermediation, further amplified by the arrival of so-called \u201cfintech\u201d. This means that a narrow focus on money supply and bank loan growth data increasingly does not capture the full picture.\r\nUS Real GDP Growth and Atlanta Fed GDPNow Forecast\r\n\r\nUS M2 growth and Nominal GDP Growth\r\n\r\nUS Credit Spreads Remain Well Behaved (For Now)\r\n\r\n\r\nThis is particularly the case in the US where the growth rate of M2 has been slowing sharply, seemingly in line with ongoing Fed balance sheet contraction. Indeed M2 growth has been running below nominal GDP growth since January.\r\n\r\nUS M2 growth slowed from 7.5% YoY in October 2016 to 3.8% in May and 4.2% in June, while nominal GDP growth rose from 4.5% YoY in 4Q17 to 4.7% YoY in 1Q18 (see previous chart). This is the opposite of a pro-growth expansionary signal. But, from an investor standpoint, money supply deceleration may not be a practical \u201cmarket timing\u201d signal of a cyclical slowdown unless it is accompanied by evidence of growing credit stress, and this is best gauged by rising credit spreads. For now, while credit spreads have risen from the lows as Fed tightening has proceeded, they remain reasonably well behaved.\r\n\r\nThe BAA-rated corporate bond yield spread over the US 10-year Treasury bond yield has risen from a low of 156bp at the beginning of February to 195bp (see following chart). While the measure of stock market volatility, known as the VIX, is almost back to the lows prevailing before the VIX surged in early February when the so-called short \u201dvol\u201d trade briefly unwound. The VIX surged from a low of 8.92 in January to an intraday-high of 50.3 in February and has since declined to 10.91 in early May and is now 13.37 (see following chart).\r\nUS BAA-rated Corporate Bond Yield Spread Over 10-year Treasury Bond Yield\r\n\r\nCBOE S&P500 Volatility Index (VIX)\r\n\r\n\r\nBut one point is self-evident. The longer Fed tightening proceeds, given the massive debt levels globally, the more likely it becomes that credit spreads widen significantly and there is a renewed upward surge in volatility. This raises the issue of one plausible explanation for recent US dollar strength with the US dollar index up 5% last quarter (see following chart). That is that it reflects a growing 'shortage' of dollars as monetary tightening proceeds, or a short squeeze, which puts pressure on borrowers of dollars internationally.\r\nUS Dollar Index\r\n\r\nThe Dramatic Growth of Offshore US Dollar Credit\r\nThe negative point here is that offshore dollar borrowing has grown dramatically since 2009. Global US dollar credit extended to non-bank borrowers outside the US totalled US$11.3 trillion at the end of 4Q17, up 94% from US$5.8 trillion at the end of 2008, according to the Bank for International Settlements. The total comprises US$5.8 trillion of debt securities and US$5.5 trillion of bank loans (see following chart).\r\nGlobal US Dollar Credit Extended to Non-bank Borrowers Outside the US\r\n\r\n\r\nIf this is the 'big picture', from a narrower emerging market debt perspective there has also been a surge in borrowing, particularly at the corporate level. Emerging markets\u2019 US dollar-denominated international debt securities outstanding have risen by 271% from US$819 billion at the end of 2008 to US$3.04 trillion at the end of 1Q18, with non-financial corporate debt accounting for US$1.22 trillion or 40% of that total (see previous chart).\r\n\r\nWithin that total, China\u2019s US dollar-denominated international debt securities surged by 26-fold from US$29.5 billion to US$768 billion over the same period with non-financial corporate debt accounting for US$388 billion or 51% of the total.\r\nEmerging Markets\u2019 International US Dollar Debt Securities Outstanding\r\n\r\n\r\nThe above data helps explain why emerging market debt has come under pressure in 2018. The JPMorgan EMBI+ emerging market sovereign bond yield has risen this year by 128bp to 7.03% in mid-June, the highest level since September 2009, and is now 6.75%. While the EMBI+ sovereign spread over US Treasuries has risen by 84bp to 413bp in mid-June and is now 391bp (see following chart). The strength of the oil-led commodity complex also means that oil importers have been more vulnerable than exporters, putting pressure in the Asian context on the likes of India and Indonesia.\r\nJPMorgan EMBI+ Sovereign Bond Yield and Spread\r\n\r\nThe Fed Believes Tightening Won't Induce Emerging Market Crisis This Time\r\nThe surge in US dollar lending to emerging markets since the global financial crisis has had two drivers, one healthy and one not so healthy.\r\n\r\nThe healthy one is the superior growth rates in many of the emerging markets and improving fundamentals that have made many of these sovereign credits a better credit risk, most particularly when compared with the deteriorating fundamentals in terms of G7 government debt.\r\n\r\nThe negative driver is the 'search for yield', and the resulting carry trade, which has been encouraged by the Fed\u2019s ultra-easy monetary policy since 2008.\r\n\r\nIt is, therefore, only natural that the Fed\u2019s attempt to unwind that policy has the potential to cause stresses and those stresses rise the more the US dollar rallies and the more dollar interest rates rise. Meanwhile the Fed believes that the emerging markets are in a better position to handle the strains from Fed tightening than in the past, in terms of the 'spillover' of US monetary policy.\r\n\r\nThus, in a speech on May 8 this year, Fed Chairman Jerome Powell stated: \u201cThe EMEs themselves have made considerable progress in reducing vulnerabilities since the crisis-prone 1980s and 1990s. Many EMEs have substantially improved their fiscal and monetary policy frameworks.\u201d\r\n\r\nWhile this is undoubtedly the case, the above comments suggest that Powell will continue to tighten monetary policy primarily with regard to domestic US considerations. Still it is also clear that the risk at the margin in the emerging world has moved from sovereigns to corporates in terms of where the greatest exposure is.
