Executive Summary Central banks are aggressively tightening policy around the world. Their ability to rein in inflation without causing a recession depends upon the level of the real neutral rates. Australia, Canada, New Zealand, and Sweden have elevated r-stars, but the picture changes drastically when their large debt loads are factored in. While real policy rates remain below r-star across DM economies for now, a more rapid decline in supply-driven inflation would correct this situation. Consequently, a global recession does not constitute our base case for the next six months, although it is a growing threat. The ECB is front-loading interest rate increases while it can, but the destination of travel is not changing significantly. Global R-Star

Bottom Line: The global r-star varies greatly around the world and debt sustainability concerns weigh on the real neutral rates of Australia, Canada, New Zealand, and Sweden. The US economy remains best capable of handling higher interest rates. Chart 1Rising Global Inflation

Inflation around G10 economies has been very strong and much more durable than originally hoped. As a result, inflation now averages 7.1% on a headline CPI basis and 4.6% based on core CPI across among G10 economies (Chart 1). Central banks are tightening policy aggressively to prevent this elevated inflation from becoming entrenched. Essentially, they are aiming to avert the emergence of the kind of inflationary mentality that prevailed in the 1970s, which caused stubborn inflation during that decade. This exercise is fraught with difficulty. The objective is to achieve a policy setting that is slightly above the neutral rate of interest, but not too much so. On the one hand, keeping policy too accommodative will increase the chances that an inflationary mentality will emerge; on the other hand, if policy is tightened too much, a recession will become unavoidable and deflationary risks will escalate. A sense of where the neutral rate for major economies lies is therefore necessary to draw that line in the sand. To do so, we estimate the real neutral rate of interest for major DM economies using the methodology we introduced seven weeks ago, when we evaluated the neutral rates for the major Eurozone economies. This exercise shows that, at the current level of interest rates and inflation, policy among major economies remains accommodative. However, if inflation decelerates sharply in the coming months in response to declining global supply constraints and lower commodity prices, the recent increase in policy rates will have already gone a long way to normalizing monetary policy around the world. A Simple Approach The methodology we use is based on the approach developed by Holston, Laubach, and Williams (HLW) to estimate the neutral real interest rate – or “r-star.” Specifically, we run regressions between the real interest rates in the US, Japan, the UK, New Zealand, Canada, Australia, Sweden, and Switzerland versus trend GDP growth and current account balances, which approximate the savings-investment balance. Mimicking the HLW methodology, the inflation expectations used to extract real interest rates from nominal short rates reflect an adaptative framework whereby inflation expectations are a function of the ten-year moving average of core CPI.1 Table 1Unadjusted R-Stars

The results are shown in Table 1. New Zealand, Australia, and Canada have the highest real-neutral rate of the major economies. They have had stronger growth over the past 20 years because of their rapid population growth caused by high immigration rates. Moreover, their commodity-based economies and their booming construction sectors pushed up investment rates, which requires high interest rates to attract sufficient savings to finance. Sweden and the US follow. These two economies have lower population growth rates than the commodity producers; nonetheless, they outperform Japan and the other European nations in the survey on that dimension. Moreover, they fare comparatively well in terms of productivity growth, which implies that their trend growth – a key driver of the neutral rate – is also higher than that of the UK, Japan, Switzerland, or the Euro Area. The US’s r-star shows up as being slightly below what would be expected based on its potential GDP growth. This surprising outcome most likely reflects the role of the dollar in global FX reserves and its standing at the core of the global financial system. These two characteristics of the greenback create an important demand for dollar-denominated assets that is dissociated from US domestic economic fundamentals. This additional demand biases downward the US real neutral rate and suggests that weak trend growth abroad and global excess savings remain important forces for US financial markets.

Japan displays a surprisingly elevated real neutral rate of 0.1%. This result reflects the limitation of the approach. Japanese interest rates have been at zero since the late 1990s and real rates have been negatively correlated with inflation because of this nominal rigidity (Chart 2). However, while Japanese inflation has averaged a paltry 0.2% since 1997, it has nonetheless fluctuated with commodity prices and global economic activity. As a result, real rates have been essentially dissociated from Japanese domestic drivers. Hence, an empirical approach based on the evolution of domestic economic variables yields poor results for Japan. Instead, the lack of inflation when public debt has increased by 200% of GDP over the past 32 years and Japan’s large net international investment position imply that its r-star is inferior to that of the other countries in the sample, and thus should lie below -1%. For the Eurozone, we use the average result of our July study, which estimated the neutral rates of Germany, France, Italy, and Spain independently. Germany flatters this estimate since its real neutral rate stands near 0%. An average, excluding Germany, would be closer to -0.5%, or well below the US r-star. Meanwhile, the Swiss r-star is depressed by both a low population growth and the Swiss exceptional savings generation, as highlighted by its current account surplus that has averaged 8% of GDP over the past 20 years. Finally, the UK’s r-star stands at the bottom of the pack. The UK’s productivity growth has been very poor over the past ten years, averaging 0.7% per annum. This points to a weak potential GDP for that economy. Moreover, the hurdles to UK growth have only increased in recent years with the implementation of Brexit, which is hurting the availability of labor in the country, while putting the UK at an even greater disadvantage in European markets, its largest export destination. What About Debt? This approach to estimating r-star ignores a key dimension: debt sustainability. If we factor in this crucial variable, the level of interest rates causing economic activity to decelerate changes drastically for many countries. Chart 3Massive Real Estates Bubbles
Massive Real Estates Bubbles
Massive Real Estates Bubbles
Since 2000, real estate prices have surged by 280%, 220%, 170%, and 200% in New Zealand, Canada, Australia, and Sweden, respectively. These gains dwarf the house price appreciation observed in the US, the UK, Japan, or Germany (Chart 3, top panel). This outperformance of house prices is particularly problematic because it does not reflect more rapid underlying cash-flow growth from the assets. Instead, the main driver of the stronger house prices in New Zealand, Canada, Australia, and Sweden has been the explosion of their price-to-rent and price-to-income ratios (Chart 3, bottom two panels). Rising real estate prices boosted economic activity relative to the underlying trend GDP of these countries. As a result, the long-term growth numbers of these four nations potentially overstate their underlying rate of growth. Even more importantly, real estate prices and activity are extremely sensitive to interest rates. Therefore, the risk of bursting bubbles in New Zealand, Canada, Australia, and Sweden limits how high interest rates may rise there without causing growth to plunge and deflationary spirals to emerge.

The accumulation of debt in these four countries accentuates the threats to growth created by real estate activity. The private-sector debt of New Zealand, Canada, Australia, and Sweden has risen much more quickly than has been the case in Germany and the US (Chart 4). Ultimately, these debt burdens create major headwinds against higher interest rates and suggest that the effective r-star of these nations lies well below the estimates constructed using only trend growth and the savings/investment balance. Table 2Drastic Changes Once Debt Is Accounted For

To account for the private-sector leverage, we estimated new debt-adjusted r-stars. The impact of high debt loads on r-star estimates is evident in Table 2. The average real neutral rate of New Zealand, Australia, and Canada drops from 1.9% to -1.9%. In fact, Australia and Canada would sport the lowest r-star estimates of the nations under study. Sweden’s neutral rate also experienced a big decline from 0.6% to 0.2%. The US r-star estimate is also lowered by the addition of debt metrics in its equation, declining from 0.2% to -0.4%. The Eurozone average r-star experiences a significant decrease as well, driven mostly by Spain and France. The Swiss economy also sports a large private debt load, and its r-star is therefore curtailed from -0.75% to -1.3%. Finally, Japan’s r-star estimate barely changes, which confirms that the approach does not work well for that country. The greatest drawback of the method is that it is backward-looking. The main force that has brought down the global r-star over the past 20 years is the collapse in trend growth among most advanced economies (Chart 5). Consequently, neutral rates could improve from their current low levels if trend growth were to pick up in the coming years. On the positive side, the current age of the capital stock in both Europe and the US is extremely advanced (Chart 6), which suggests that a capex upturn is likely. Such an upturn would boost productivity and lift the r-star among most major economies. On the negative side, the growth of human capital is deteriorating as educational attainment stalls among most DM nations. The decline in the growth rate of human capital is a large threat to productivity over the coming decades. These problems are magnified in the Eurozone, as its high degree of economic fragmentation, lack of common fiscal policy, and higher regulatory burden create further handicaps to trend growth.

Bottom Line: Estimating the real neutral rates for the global economy often relies on trend growth and the savings/investment balance. However, such an approach often misses the vulnerability to higher interest rates created by high private-sector indebtedness. If this constraint is considered, the high r-star recorded in countries like New Zealand, Australia, or Canada is reduced dramatically. The US r-star also declines but significantly less so. As we already showed seven weeks ago, the same phenomenon is also visible in the Eurozone, albeit driven by France and Spain, not Germany or Italy. Investment Implications There are three main conclusions from the analysis above. First, the risk of a financial accident in commodity-producing economies is growing increasingly large. On the one hand, economies like New Zealand, Australia, and Canada are buoyed by the recent surge in commodity prices, with agricultural prices up 90% since their 2020 lows, metal prices up 68%, and energy prices up 340% since April 2020. On the other hand, the inflationary pressures created by robust commodity sectors invite the RBNZ, the RBA, and the BoC to lift interest rates quickly, which is hurting massively indebted private sectors. Already, in response to the 275bps and 300bps of hikes implemented by the RBNZ and the BoC, house prices in New Zealand have begun to buckle, down 12% and since their more recent peaks, and they are expected to plunge by as much as 25% in Canada by the end of next year. Chart 7NZD And CAD At A Disadvantage

This suggests that non-commodity equities in Canada, Australia, and New Zealand, especially financials, could experience significant periods of underperformance, both against their domestic equity benchmark and global market averages. Additionally, while the NZD, AUD, and CAD all benefit from improving terms of trades, the potential for domestic weakness is such that these currencies are likely to lag their historical sensitivity to commodity price fluctuations. In fact, according to BCA’s foreign exchange strategist, the New Zealand and Canadian dollars are among the most expensive currencies in the G10 (Chart 7), and thus, it is likely to underperform other pro-cyclical currencies once the USD bull market reverses. Second, the neutral rate in the US has risen by 200bps relative to the rest of the world over the past seven years. The US economy has undergone a long deleveraging period in the wake of the GFC, which means that its private-debt-to-GDP ratio has declined relative to other advanced economies. Consequently, the vulnerability of the US economy to higher interest rates has decreased, even if relative US trend growth has not improved meaningfully. The market implications of this pickup in the neutral rate are manifold. To begin with, it allows US rates to rise further relative to other DM economies. BCA’s Global Fixed Income Strategy team continues to underweight US Treasurys in global fixed-income portfolios, especially relative to German Bunds (Chart 8). As a corollary, it also means that US financials are likely to continue to outperform their foreign peers, especially Canadian and Australian ones which will bear the brunt of the negative consequences of their debt bubbles. The increase in the US r-star relative to the rest of the world has been a key contributor to the dollar rally. It helps explain why the recent dollar strength has not hurt relative profit growth (Chart 9). However, the dollar is trading at a 32% premium to its purchasing power parity, or the same overvaluation as in 1985 and 2001. Thus, with the worsening US balance of payment picture, the US dollar is vulnerable to an eventual improvement in global growth next year. Chart 8US Rate Differentials Have Upside

Finally, despite the recent increase in rates, the high level of inflation recorded around the world implies that real policy rates are still well below r-star for major global economies, whether one uses actual inflation or the smooth formulation recommended by the HLW paper (Chart 10). This suggests that a recession is unlikely, especially in the US. The recession threat is higher in Europe but has little to do with policy. It is mostly a consequence of the massive terms of trade shock caused by the sudden jump in European energy prices in the wake of the Ukrainian war. However, because policy remains accommodative even in Europe, it follows that the Eurozone economy will rebound quickly once the worst of the energy shock is over next spring. Some humility is required. It is hard to gauge how much of the inflation surge over the past 18 months reflects supply factors. If inflation suddenly becomes much weaker because the easing in supply constraints has a greater-than-anticipated impact on inflation, real interest rates would jump rapidly around the world. In this scenario, policy rates could rise quickly and overtake r-star. This would mean that the disinflation impulse could rapidly morph into an outright deflationary environment, which implies that the odds of a deflationary bust like the one experienced in 1921 is greater than the market currently prices in. Bottom Line: The debt-fueled real estate bubbles in the dollar-bloc economies suggests that they are at a greater risk of a financial accident than the US or the Eurozone. As a result, their financial sector looks vulnerable. Meanwhile, the higher US r-star compared to that of the rest of the world will continue to support higher yields in the US rather than in Europe or Japan. This phenomenon has been hugely positive for the US dollar, but it has likely run its course. Finally, global real interest rates remain below r-star estimates. Hence, the current slowdown is likely to prove to be a mid-cycle slowdown and Europe will rebound quickly from a potential recession caused by the recent surge in its energy prices. The ECB Joins The 75bps Club Last week, the ECB increased interest rates by 75bps, which brought its deposit rate to 0.75%. Interestingly, the euro did not rally much in response to this policy decision, even though it has not been fully discounted by the market. At first glance, the lack of responsiveness from European assets seems strange, especially since the vote for a 75bps rate hike was unanimous. The ECB is taking advantage of strong economic numbers to push up rates rapidly. The Eurozone Q2 GDP growth was robust at 0.6%, while the unemployment rate hit an all-time low of 6.6%. Meanwhile, inflation continues to beat consensus forecasts, with Eurozone core CPI and headline CPI standing at 4.3% and 9.1%, respectively in August. Chart 11Big ECB Revisions

The market believes that more rapid interest rate hikes now will not translate into a much higher terminal rate, with the expected rates for June 2023 moving from 2.2% on September 7th to 2.4% after last Thursday’s decision. The ECB may have increased its inflation forecasts for the whole horizon, but it has also brought down GDP forecasts to 0.9% and 1.9% in 2023 and 2024, respectively (Chart 11). Moreover, ECB President Christine Lagarde went out of her way to telegraph to investors that the number of upcoming hikes was finite. The jumbo hike does not spell the start of a euro rally—for now. First, the lack of major change in the ECB’s terminal deposit rate is more important than the more rapid pace of hikes for the remainder of 2022. Second, the Fed is also lifting rates faster than investors expected ahead of the Jackson Hole meeting three weeks ago. Third, the euro remains vulnerable to any flare-ups in the energy market. True, natural gas and electricity prices have recently fallen, but the situation in Ukraine continues to be highly fluid, which suggests that volatility will linger in the energy market over the coming weeks. Despite the near-term hurdles, the euro’s medium-term outlook is brightening. We are gaining confidence in our thesis that energy prices will peak once natural gas inventories have reached approximately 90% by November. Additionally, the support of the Governing Council’s doves for a 75bps hike suggests that they received something in exchange for their votes. In our view, this “something” is an activation of the Transmission Protection Instrument (TPI) before year-end. The TPI activation will allow for a normalization of the risk premia in the Italian debt market and will support the ECB’s ability to increase interest rates further down the road, despite the much lower r-star in Italy, Spain, and France than in Germany (Table 3).

Bottom Line: The ECB may have delivered a jumbo hike last week, but its market impact was muted. Investors understand full well that the ECB is taking advantage of the recent bout of robust economic activity to front-load interest rate increases ahead of a likely economic contraction in Q4 2022 and Q1 2023. As a result, the terminal rate estimates have scarcely moved. Ultimately, we expect the ECB deposit rate to settle between 1.5% and 2% in the summer of 2023. While the move may not provide much of a boost to the euro in the near term, conditions are falling into place for a euro rally later this year.
