Market strategists and policymakers are putting too much emphasis on a trade deal between the United States and China, and it's quite likely that whatever is agreed will disappoint.
Even the most optimistic assumptions are unlikely to change the trend of weak global growth.
There is a problem of diagnosis. The current economic slowdown is not entirely due to the trade tensions between the United States and China, but mostly due to a combination of debt saturation and end-of-cycle signals. These were quite evident in China months before any tariffs were announced.
The diminishing returns of the Chinese and euro zone stimulus plans have been clear since the end of 2016 and 2017, respectively. In the case of emerging economies, the 2018 weakness was just the result of years of building fiscal and trade imbalances betting on a constantly weakening dollar and low rates.
The main reason why economies are slowing down is fundamentally the result of the debt excess of the past years, not trade wars. With global debt rising above 300 percent of gross domestic product, according to the Institute of International Finance, and very low productivity growth in developed countries, it's not surprising that additional units of debt fail to deliver the expected growth, while excess capacity hinders investment and trade.
Low interest rates and high liquidity have also generated collateral damages. A recent study by the National Bureau of Economic Research concludes that aggressive monetary policies lead to "rising market concentration, reduced dynamism, a widening productivity-gap between industry leaders and followers, and slower productivity growth."
Another negative side effect is the rise of zombie companies, those that cannot cover interest expenses with operating profits for an extended period of time. According to Ryan Banerjee, an economist at the Bank of International Settlements, the percentage of zombie firms has risen to multi-year highs.
We must also understand that the concerns about liquidity created a large impact in global markets, as investors worried about central banks normalizing policy. 2018 was the first year in which global money supply fell after years of exceptionally high growth. Central banks have changed their communication to a more dovish tone, but this is not necessarily going to prevent a change of economic cycle, rather the opposite. Failure to normalize sends a message of deteriorating economic signals.
These issues are unlikely to end due to a trade deal. Cycles change. China's slowdown was inevitable and a reduction in U.S. growth estimates is logical after the longest expansion in history.
Remember that the same reason why tariffs had a relatively small impact on the global economy shows why a new trade agreement is unlikely to change the current trend. Those tariffs affected a relatively small proportion of the global economy.
A new trade deal will probably have a marginal effect on the Chinese and U.S. economies.
China is still in the process of opening its economy, and its main challenges remain: An excessively indebted model, large overcapacity and persistent capital controls. The United States can put pressure on China to import more, but there is little evidence that the Asian giant's purchases are less than it needs. If anything, inventories show the opposite. It is rather difficult to envision a drastic change in the trade balance between the two countries and even less an important net change in total trade.
Market sentiment is improving as news of a trade summit hit the headlines, but if there was a radical change in trade dynamics it would have already been leaked. Sentiment may have driven a significant recovery in cyclical stocks, emerging markets and the price of commodities, but the fundamentals of supply, demand, trade and economic growth may see little to no impact from a trade deal.
U.S. Treasury and German sovereign bond yields have been falling while the U.S. dollar was quietly strengthening despite dovish central banks and rumors of an imminent trade deal. What does this tell us? Possibly, that the real impact of a trade deal is negligible and that disinflation and low global growth risks remain.
