Highlights It may seem self-evident that most governments are overly indebted, but both theory and evidence suggest otherwise. Higher debt today does not require higher taxes tomorrow if the growth rate of the economy exceeds the interest rate on government bonds. Not only is that currently the case, but it has been the norm for most of history. Unlike private firms or households, governments can choose the interest rate at which they borrow, provided that they issue debt in their own currencies. Ultimately, inflation is the only constraint to how large fiscal deficits can get. Today, most governments would welcome higher inflation. There are increasing signs China is abandoning its deleveraging campaign. Fiscal policy will remain highly accommodative in the U.S. and will turn somewhat more stimulative in Europe. Remain overweight global equities/underweight bonds. We do not have a strong regional equity preference at the moment, but expect to turn more bullish on EM versus DM by the middle of this year. Feature A Fiscal Non-Problem? Debt levels in advanced economies are higher today than they were on the eve of the Global Financial Crisis. Rising private debt accounts for some of this increase, but the lion’s share has occurred in government debt (Chart 1). Chart 1Global Debt Levels Have Risen, Especially In The Public Sector Not surprisingly, rising public debt levels have elicited plenty of consternation. While there has been a lively debate about how fast governments should tighten their belts, few have disputed the seemingly self-evident opinion that some degree of “fiscal consolidation” is warranted. Given this consensus view, one would think that the economic case for public debt levels being too high is airtight. It’s not. Far from it. Debt Sustainability, Quantified Start with the classic condition for debt sustainability, which specifies the primary fiscal balance (i.e., the overall balance excluding interest payments) necessary to maintain a constant debt-to-GDP ratio (See Box 1 for a derivation of this equation). An increase in the economy’s growth rate (g), or a decrease in real interest rates (r), would allow the government to loosen the primary fiscal balance without causing the debt-to-GDP ratio to increase (Chart 2).1 If the government were to ease fiscal policy beyond that point, debt would rise in relation to GDP. But by how much? It is tempting to assume that the debt-to-GDP ratio would then begin to increase exponentially. However, that is only true if the interest rate is higher than the growth rate of the economy. If the opposite were true, the debt-to-GDP ratio would rise initially but then flatten out at a higher level.2 A Fiscal Free Lunch The last point is worth emphasizing. As long as the interest rate is below the economic growth rate, then any primary fiscal balance – even a permanent deficit of 20%, or even 30% of GDP – would be consistent with a stable long-term debt-to-GDP ratio. In such a setting, the government could just indefinitely rollover the existing stock of debt, while issuing enough new debt to cover interest payments. No additional taxes would be necessary. In fact, stabilizing the debt-to-GDP ratio becomes easier the higher it rises. Chart 3 shows this point analytically. Ah, one might say: If the government issues a lot of debt, then interest rates would rise, and before we know it, we are back in a world where the borrowing rate is above the economy’s growth rate, at which point the debt dynamics go haywire. Now, that sounds like a sensible statement, but it is actually quite misleading. As long as a government is able to issue its own currency, it can always create money to pay for whatever it purchases. If people want to turn around and use that money to buy bonds, they are welcome to do so, but the government is under no obligation to pay them the interest rate that they want. If they do not wish to hold cash, they can always use the cash to buy goods and services or exchange it for foreign currency. As long as a government is able to issue its own currency, it can always create money to pay for whatever it purchases. Wouldn’t that cause inflation and currency devaluation? Yes, it might, and that’s the real constraint: What limits the ability of governments with printing presses to run large deficits is not the inability to finance them. Rather, it is the risk that their citizens will treat their currencies as hot potatoes, rushing to exchange them for goods and services out of fear that rising prices will erode the purchasing power of their cash holdings. When Is Saving Desirable? The reason governments pay interest on bonds is because they want people to save more. However, more savings is not necessarily a good thing. This is obviously the case when an economy is depressed, but it may even be true when an economy is at full employment. Just like someone can work so much that they have no time left over for leisure, or buy a house so big that they spend all their time maintaining it, it is possible for an economy to save too much, leading to an excess of capital accumulation. Under such circumstances, steady-state consumption will be permanently depressed because so much of the economy’s resources are going towards replenishing the depreciation of the economy’s capital stock. Economists have a name for this condition: “dynamic inefficiency.” What determines whether an economy is dynamically inefficient? As it turns out, the answer is the same as the one that determines whether debt ratios are on an explosive path or not: The difference between the interest rate and the economy’s growth rate. Economies where interest rates are below the growth rate will tend to suffer from excess savings. In that case, government deficits, to the extent that they soak up national savings, may increase national welfare. r < g Has Been The Norm Today, the U.S. 10-year Treasury yield stands at 2.69%, compared to the OECD’s projection of nominal GDP growth of 3.8% over the next decade. The gap between projected growth and bond yields is even greater in other major economies (Chart 4). Granted, equilibrium real rates are likely to rise over the next few years as spare capacity is absorbed. Structural factors might also push up real rates over time. Most notably, the retirement of baby boomers could significantly curb income growth, leading to a decline in national savings. Chart 5 shows that the ratio of workers-to-consumers globally is in the process of peaking after a three-decade long ascent. Economic growth could also fall if cognitive abilities continue to deteriorate, a worrying trend we discussed in a recent Special Report.3 Chart 5The Global Worker-To-Consumer Ratio Has Peaked It may take a while before real rates rise above GDP growth. Still, it may take a while before real rates rise above GDP growth. As Olivier Blanchard, the former chief economist at the IMF, noted in his Presidential Address to the American Economics Association earlier this year, periods in U.S. history where GDP growth exceeds interest rates have been the rule rather than the exception (Chart 6).4 The same has been true for most other economies.5 Chart 6GDP Growth Above Interest Rates: Historically, The Rule, Not The Exception What’s Next For Fiscal Policy? Austerity fatigue has set in. In the U.S., fiscally conservative Republicans, if they ever really existed, are a dying breed. Trump’s big budget deficits and his “I love debt” mantra are the waves of the future. For their part, the Democrats are shifting to the left, with the “Green New Deal” proposal being the latest manifestation. The case for fiscal stimulus is stronger in the euro area than for the United States. The European Commission expects the euro area to see a positive fiscal thrust of 0.40% of GDP this year, up from a thrust of 0.05% of GDP last year (Chart 7). This should help support growth. Chart 7The Euro Area Will Benefit From A Modest Amount Of Fiscal Easing This Year Additional fiscal easing would be feasible. This is clearly true in Germany, but even in Italy, the cyclically-adjusted government primary surplus is larger than what is necessary to stabilize the debt ratio.6 Unfortunately, the situation in southern Europe is greatly complicated by the ECB’s inability to act as an unconditional lender of last resort to individual sovereign borrowers. When a government cannot print its own currency, its debt markets can be subject to multiple equilibria. Under such circumstances, a vicious spiral can develop where rising bond yields lead investors to assign a higher default risk, thus leading to even higher yields (Chart 8). Mario Draghi’s now-famous “whatever it takes” pledge has gone a long way towards reassuring bond investors. Nevertheless, given the political constraints the ECB faces, it is doubtful that Italy or other indebted economies in the euro area will be able to pursue large-scale stimulus. Instead, the ECB will keep interest rates at exceptionally low levels. A new round of TLTROs is also looking increasingly likely, which should protect against a rise in bank funding costs and a potential credit crunch. Our European team believes that a TLTRO extension would be particularly helpful to Italian banks. Even in Italy, the cyclically-adjusted government primary surplus is larger than what is necessary to stabilize the debt ratio. Despite having one of the highest sovereign debt ratios in the world, Japan faces no pressing need to tighten fiscal policy. Instead of raising the sales tax this October, the government should be cutting it. A loosening of fiscal policy would actually improve debt sustainability if, as is likely, a larger budget deficit leads to somewhat higher inflation (and thus, lower real borrowing rates) and, at least temporarily, faster GDP growth. We expect the Abe government to counteract at least part of the sales tax increase with new fiscal measures, and ultimately to abandon plans for further fiscal tightening over the next few years. In the EM space, Brazil, Turkey, and South Africa are among a handful of economies with vulnerable fiscal positions. They all have borrowing rates that exceed the growth rate of the economy, cyclically-adjusted primary budget deficits, and above-average levels of sovereign debt (Chart 9). In contrast, China stands out as having the biggest positive gap between projected GDP growth and sovereign borrowing rates of any major economy. The problem is that the main borrowers have been state-owned companies and local governments, neither of which are backstopped by the state. Not officially, anyway. Unofficially, the government has been extremely reluctant to allow large-scale defaults anywhere in the economy. Despite all the rhetoric about market-based reforms, they are unlikely to start now. Historically, the Chinese government has allowed credit growth to reaccelerate whenever it has fallen towards nominal GDP growth. As we recently argued in a report entitled “China’s Savings Problem,” China needs more debt to sustain aggregate demand.7 Historically, the government has allowed credit growth to reaccelerate whenever it has fallen towards nominal GDP growth (Chart 10). The stronger-than-expected jump in credit origination in January suggests that we are approaching such an inflection point. Chart 10Historically, China Has Scaled Back On Deleveraging When Credit Growth Has Fallen Close To Nominal GDP Growth Investment Conclusions The consensus economic view is that deflation is a much harder problem to overcome than inflation. When dealing with inflation, all you have to do is raise interest rates and eventually the economy will cool down. With deflation, however, a central bank could very quickly find itself up against the zero lower bound constraint on interest rates, unable to ease policy any further via conventional means. While this standard argument is correct, it takes a very monetary policy-centric view of macroeconomic policy. When interest rates are low, fiscal policy becomes very potent. Indeed, the whole notion that deflation is a bigger problem than inflation is rather peculiar. Just as it is easier to consume resources than to produce them, it should be easier to get people to spend than to save. People like to spend. And even if they didn’t, governments could go out and buy goods and services directly. Looking out, our bet is that policymakers will increasingly lean towards the ever-more fiscal stimulus. If structural trends end up causing the so-called neutral rate of interest to rise – the rate of interest that is necessary to avoid overheating – policymakers will have no choice but to eventually raise rates and tighten fiscal policy (Box 2). However, they will only do so begrudgingly. The result, at least temporarily, will be higher inflation. Fixed-income investors should maintain below benchmark duration exposure over both a cyclical and structural horizon. Reflationary policies that increase nominal GDP growth will help support equities, at least over the next 12 months. Chart 11 shows that corporate earnings tend to accelerate whenever nominal GDP growth rises. We upgraded global equities to overweight following the December FOMC meeting selloff. While our enthusiasm for stocks has waned with the year-to-date rally, we are sticking with our bullish bias. Chart 11Earnings And Nominal GDP Growth Tend To Move In Lock-Step A reacceleration in Chinese credit growth will put a bottom under both Chinese and global growth by the middle of this year. As a countercyclical currency, the dollar will likely come under pressure in the second half of this year. Until then, we expect the greenback to be flat-to-modestly stronger. The combination of faster global growth and a weaker dollar later this year will be manna from heaven for emerging markets. We closed our put on the EEM ETF for a gain of 104% on Jan 3rd, and are now outright long EM equities. I do not have a strong view on the relative performance of EM versus DM at the moment, but expect to shift EM equities to overweight by this summer.8 Peter Berezin, Chief Global Strategist Global Investment Strategy peterb@bcaresearch.com Box 1 The Arithmetic Of Debt Sustainability Box 2 Debt Sustainability And Full Employment: The Role Of Fiscal And Monetary Policy Policymakers should strive to stabilize the ratio of debt-to-GDP over the long haul, while also ensuring that the economy stays near full employment. The accompanying chart shows the tradeoffs involved. The DD schedule depicts the combination of the primary fiscal balance and the gap between the borrowing rate and GDP growth (r minus g) that is consistent with a stable debt-to-GDP ratio. In line with the debt sustainability equation derived in Box 1, the slope of the DD schedule is simply equal to the debt/GDP ratio. Any point below the DD schedule is one where the debt-to-GDP ratio is rising, while any point above is one where the ratio is falling. The EE schedule depicts the combination of the primary fiscal balance and r - g that keeps the economy at full employment. The schedule is downward-sloping because an increase in the primary fiscal balance implies a tightening of fiscal policy, and hence requires an offsetting decline in interest rates. Any point above the EE schedule is one where the economy is operating at less than full employment. Any point below the EE schedule is one where the economy is operating beyond full employment and hence overheating. Suppose there is a structural shift in the economy that causes the neutral rate of interest – the rate of interest consistent with full employment and stable inflation – to increase. In that case, the EE schedule would shift to the right: For any level of the fiscal primary balance, the economy would need a higher interest rate to avoid overheating. The arrows show three possible “transition paths” to a new equilibrium. Scenario #1 is one where policymakers raise rates quickly but are slow to tighten fiscal policy. This results in a higher debt-to-GDP ratio. Scenario #2 is one where policymakers tighten fiscal policy quickly but are slow to raise rates. This results in a lower debt-to-GDP ratio. Scenario #3 is one where the government drags its feet in both raising rates and tightening fiscal policy. As the economy overheats, real rates actually decline, sending the arrow initially to the left. This effectively allows policymakers to inflate away the debt, leading to a lower debt-to-GDP ratio. Note: In Scenario #2, and especially in Scenario #3, the DD line will become flatter (not shown on the chart to avoid clutter). Consequently, the final equilibrium will be one where real rates are somewhat higher, but the primary fiscal balance is somewhat lower, than in Scenario #1. Footnotes 1 One can equally define the interest rate and GDP growth rate in nominal terms (see Box 1 for details). 2 Japan is a good example of this point. The primary budget deficit averaged 5% of GDP between 1993 and 2010, a period when government net debt rose from 20% of GDP to 142% of GDP. Since then, Japan’s primary deficit has averaged 5.1% of GDP, but net debt has risen to only 156% of GDP (and has been largely stable for the past two years). 3 Please see Global Investment Strategy Special Report, “The Most Important Trend In The World Has Reversed And Nobody Knows Why,” dated February 1, 2019. 4 Olivier Blanchard, “Public Debt And Low Interest Rates,” Peterson Institute for International Economics and MIT American Economic Association (AEA) Presidential Address, (January 2019). 5 Paolo Mauro, Rafael Romeu, Ariel Binder, and Asad Zaman, “A Modern History Of Fiscal Prudence And Profligacy,” IMF Working Paper, (January 2013). 6 The Italian 10-year bond yield is 2.83% while nominal GDP growth is 2.64%. Multiplying the difference by net debt of 118% of GDP results in a required primary surplus of .22% of GDP that is necessary to stabilize the debt-to-GDP ratio. This is lower than the IMF’s 2018 estimate of cyclically-adjusted government primary surplus of 2.14%. 7 Please see Global Investment Strategy Weekly Report, “China’s Savings Problem,” dated January 25, 2019. 8 Please note that my colleague, Arthur Budaghyan, BCA’s Chief EM strategist, remains bearish on both EM and DM equities and expects EM to underperform DM over the coming months.
