'Reaching for yield' into corporate debt takes on a risky hue
William White, a Canadian, became the top economist at the Bank for International Settlements (BIS) over a 14-year career to 2008 at the bank owned by central banks. Among those who heard of him, White became known as “the man no one wanted to hear”.
From 2003, in an era when central banks prioritised inflation targeting (and yet the response to every crisis by the ‘maestro’ Federal Reserve chairman Alan Greenspan was to slash the US cash rate), White and his team studied the data the BIS gathered on banks worldwide. They judged that low interest rates meant too much money was sloshing around. They observed a bubble developing in US housing. They noted the obscure way mortgages were being securitised. They spotted the stellar ratings on dodgy mortgage-backed securities. They observed the increase in risky loans.
White ensured that BIS publications were sprinkled with warnings that bubbles lead to financial upheavals. On top of that, White aired his concerns through speeches and papers.
Two of White’s efforts stood out. The first was in 2003 at Jackson Hole in the US at the annual gathering of central bankers that included Greenspan, who then publicly snubbed White for his remarks. What upset Greenspan was that White warned that, even though inflation was docile, liberalised financial markets allowing investors to take too much risk meant that “financial imbalances could build up … possibly resulting in financial instability” so damaging that “central banks may need to push policy rates to zero”. White’s other warning of note was a 2006 paper titled Is price stability enough? In it, White concluded that "one hopes that it will not require a disorderly unwinding of current excesses to prove convincingly that we have indeed been on a dangerous path" by targeting inflation only.
The US subprime crisis of 2007 that morphed into the global financial crisis of 2008 was, of course, that chaotic unravelling. While no household name, White is acknowledged as the economist who foresaw the calamity, and the BIS is regarded as among the foremost voices on financial risks.
That is the context in which to view a paper the BIS released in March this year that warns about the “bankruptcy gap”. This term refers to the difference between expected and actual – “very low” – global bankruptcies since the pandemic began, even fewer insolvencies in some countries. The BIS said ample credit from banks and the corporate-debt market means lockdown-hit companies in “airline, hotel, restaurant and leisure sectors" in particular are surviving on debt, not economic viability. “The more worrying scenario is the combination of higher debt levels and depressed earnings for credit-dependent firms”, the BIS said, essentially warning that a spate of defaults could threaten financial stability.
The concerns are centred on the lower-rated – or ‘junk’ – segments of the corporate debt market – where the US$11 trillion US market (of which about US$3 trillion is junk debt), as the world’s benchmark, gets outsized attention. So too does China’s US$17 trillion corporate-debt market, where recent defaults and property giant Evergrande’s woes pushed the average yield on Chinese high-yield bonds issued offshore from 9.56% on June 30 to 15.45% at the end of September.
The risky form of finance that gained in global popularity from the 1980s has turned more hazardous due to ultra-loose monetary policies and the decision by key central banks to backstop their corporate bond markets – most notably, the Fed’s historic decision in March last year to buy US investment-grade corporate bonds. The combination prompted investors to pile into risky company debt to earn their required returns.
This ‘reach for yield’ means that junk bonds are priced at little premium over investment-grade corporate debt and government bonds. In the US on September 30, for instance, the ICE BofA US High Yield Index Option Adjusted Spread of junk to government bonds had plunged from a record of 11.38% just before the Fed began buying corporate bonds on March 23 last year to only 4.21% on September 30, not far above the 3.94% set on September 15, its lowest since just before the subprime crisis of 2007. Given that companies have used record low interest rates to lengthen the maturity of their debt holdings – and default risk rises over time – the barometer is at a de facto historic low.
The rating companies are sounding similar concerns to the BIS (as, less directly, is the OECD). Moody’s and S&P Global Ratings told the Financial Times in August that a borrowing frenzy amounting to a record US$786 billion in “speculative-grade” (the junkiest) debt so far in 2021 amid “clear signs of risk taking” meant “the current easy access to corporate financing might be laying the foundation for a future debt crisis” from “elevated levels of defaults”. The frenzy this year comes after a record US$1 trillion was invested in corporate debt.
The wider concern is the systemic threat. Even if any corporate-bond crisis fails to inflict such damage, higher company debt loads foreshadow a downturn because higher repayments would force businesses to shed staff and refrain from investing as they prioritised reducing their debts (a ‘balance sheet’ recession, in the jargon).
The risks around speculative-grade corporate debt raise the broader question of whether or not prolonged central-bank asset buying, by forcing investors to take excessive risk, could prove counterproductive. The verdict on the worth of quantitative easing will be obvious if junk bonds are at the centre of the next crisis.
Let’s acknowledge that bond investors helped many viable companies survive an emergency. Let’s note too that the BIS is not pushing the warnings about the bankruptcy gap with the same urgency with which White voiced his concerns. Many forecasts obviously prove inaccurate, including those of the BIS, which is prone to alarm. If higher inflation proves transitory as officials expect, low interest rates could persist for a while yet and the reach for yield might prove innocuous. But benign investment markets might only prompt more investors to seek higher and riskier debt-based returns and that might presage a delayed, but bigger, blow-up. A crisis could start in many of the asset classes (including US housing again) that have reached record highs in recent years. For sure. But problems arising anywhere could spread to junk bonds and magnify any upheaval.
As household-name Warren Buffett warned in February 2020 as covid-19 was going global: “Reaching for yield is really stupid” that could have major “consequences over time”. No doubt White in his near-anonymity would agree.
No way out
On 23 May 2013, minutes were released from the Fed’s policy-setting board meeting held about three weeks earlier. The document showed one board member, Esther George, president (still) of the Federal Reserve Bank of Kansas City, disagreed with the decision to keep monetary policy ultra-loose – where the cash rate was at zero and the Fed was buying assets worth US$85 billion a month. George “preferred to signal a near-term tapering of asset purchases”, the record showed. That phrase was among warnings about impending rises in bond yields that triggered such a violent reaction on financial markets the episode became known as the ‘taper tantrum.’
The same day those minutes were released, Fed chairman Ben Bernanke justified an expected tapering by warning Congress that a long period of low interest rates could “undermine financial stability” … because “investors or portfolio managers dissatisfied with low returns may reach for yield by taking on more credit risk, duration risk or leverage”.
Jerome Powell now leads a Fed that is buying assets at a rate of at least US$120 billion a month, whereby the central bank creates money (electronically) as an asset on its balance sheet and buys financial securities in the secondary market with interest-paying reserves. As the Fed’s balance sheet has bloated by US$6 trillion over the past eight years to stretch to 30% of US GDP (while the total of major central banks is US$18 trillion), the risks are probably greater. While central-bank asset buying in emergencies can stabilise financial markets (as the Fed’s corporate-bond buying did in 2020), the question being raised as investors await signs of an imminent tapering is whether prolonged asset buying might prove counterproductive.
Disadvantages accruing from quantitative easing (some of which are intertwined with the zero cash-rate setting) build the case for why the asset buying needs to be unwound as soon as it can. One drawback is that asset buying lowers bond yields and thereby hurts savers who rely on interest income. That counteracts, to some extent, the boost lower rates give to the economy. Another is that quantitative easing seems to bolster asset prices to such an extent that risk appears mispriced and capital appears misallocated, while inequality rises. A third is that central-bank asset purchases create a future fiscal liability for taxpayers, even if it reduces government borrowing costs in the short term and the interest earned on a central bank’s debt holdings is income for the treasury. Central banks pay a market-based rate of interest to holders of their reserves to stop these sums being lent out and risking inflation. Higher interest rates would thus burden public finances while giving banks unearned income. A fourth is that quantitative easing shortens the duration of the government’s debt (by substituting overnight reserves for longer-term securities) at a time when low interest rates mean the government should be doing the opposite.
Another is that quantitative easing undermines the independence of central banks – and thus their inflation-fighting credibility – by blurring the distinction between fiscal and monetary policies. A sixth is that, given the fragility of central-bank independence come an emergency, elevated government debt could prompt politicians to pressure central banks not to raise interest rates to control inflation because higher rates might trouble public finances. A further drawback is that central-bank actions can reduce the pressure on political leaders to use fiscal and other policies to help economies, especially if the asset buying reaches into funding the government’s deficit.
Last, and of relevance to the corporate-debt market, the asset buying can encourage excessive risking taking that results in a crisis. That’s why central banks are afraid to reduce, let alone end, their purchases. The UK’s House of Lords might best sum up this dilemma with the title of its evaluation of central-bank asset buying: Quantitative Easing – a dangerous addiction? As the report notes in what it calls “the no-exit paradigm,” no central bank has managed to reverse its asset buying over the medium to long term. The Fed has probably come closest. Many argue the economy could have absorbed Fed tapering in 2013.
The concern now is that Fed tapering could well be the spark of trouble for corporate bond yields. Faster inflation – and US consumer prices jumped 5.4% in the 12 months to August – could hasten the day when the Fed needs to tighten monetary policy.
Come any tapering, government yields are likely to rise and so too the premium on junk versus haven assets. At the same time, higher interest rates could slow economic growth and retard company sales. Yet interest payments would still need to be paid and maturing debt replaced by fresh borrowings. Yields on downgraded company debt could soar if the rating reduction were to sink from investment to non-investment grade. Debt reduced to junk (‘fallen angels’) reduces the number of investors who can invest because they have mandated minimum ratings on investments.
Fed members have much to consider as they ponder the ending of the Fed’s promiscuous monetary policy, though there’s less pressure on Kansas City’s George as she has no vote this time. Wonder what the BIS’s White, now in retirement, might advise.
