Planes, politics & viruses: Emerging risks to US growth?

Episode Summary

Executive Summary: Barclays’ Jeff Mellie and economist Michael Gapin assess whether three coincident risks—Boeing’s 737 MAX shutdown, the novel coronavirus, and Democratic primary uncertainty—could collectively weaken an otherwise resilient U.S. expansion. Mellie argues the concentration and timing of shocks may matter more than each alone; Gapin sees mostly temporary, manageable effects with limited U.S. growth damage and likely rebounds later in the year.

Main Topics: Boeing 737 MAX production halt (Priority: 5/5): The hosts examine the economic impact of Boeing suspending 737 MAX production after safety and certification problems, focusing on its surprisingly large contribution to U.S. GDP and whether the disruption could spill over to suppliers and jobs. Coronavirus and global spillovers (Priority: 5/5): They debate how the novel coronavirus could affect Chinese growth, global travel, supply chains, and U.S. activity. Mellie emphasizes concentrated hits to tourism and trade; Gapin expects limited U.S. damage except in severe scenarios. Business confidence and investment risk (Priority: 4/5): Both speakers agree uncertainty from trade, the virus, and politics could discourage business investment, which is important because weak 2019 investment needs to rebound to sustain the expansion and labor market strength. Democratic primary and policy uncertainty (Priority: 3/5): The discussion considers whether a progressive nominee could unsettle markets and reduce business confidence, though Gapin argues it is too early to infer economic consequences from Iowa or candidate platforms. Resilience of the U.S. expansion (Priority: 4/5): A recurring theme is whether the longest U.S. expansion on record can absorb multiple shocks. Gapin argues the economy is durable and should rebound; Mellie warns that simultaneous headwinds may interact more dangerously than models imply.

Key Arguments: Mellie argues that the market is underestimating the combined effect of multiple risks occurring at the same time, even if each looks manageable in isolation. Gapin counters that the U.S. economy is resilient enough to absorb Boeing and coronavirus shocks, especially if disruptions are temporary and followed by a rebound. Boeing is economically important because each 737 MAX adds substantial domestic value, so a production halt can shave meaningfully from Q1 GDP. Mellie argues Boeing’s damage may be more severe than a simple GDP estimate suggests because the losses are concentrated in one sector and could trigger layoffs or supplier failures. For the coronavirus, Gapin says only severe Chinese-growth downside would materially affect the U.S., since the U.S. is not highly export-driven. Mellie stresses that tourism and supply-chain disruptions are concentrated, immediate, and harder to recapture than general macro slowdowns. Both agree business investment is vulnerable to uncertainty from trade, the virus, and politics, and weak investment could eventually threaten labor-market strength. On politics, Gapin says Iowa is not decisive and investors should focus on South Carolina and Super Tuesday rather than overreacting to early primary outcomes.

Data Points: USMCA and phase one China deal: 2 trade risks resolved positively - These agreements reduced trade tensions at the end of 2019 and improved market sentiment. U.S. government funding: 2 years - Federal funding agreement removed near-term shutdown risk. U.S. equity market rally: substantial - Markets reacted positively to the resolved risks and improved outlook. Boeing 737 MAX direct GDP value added per plane: about $120 million - Estimated total value added to GDP from each plane. Boeing 737 MAX domestic value added per plane: about $80 million - Estimated after roughly one-third import content is excluded. 737 MAX production rate before suspension: 42 planes a month - Production level prior to the halt. 737 MAX production halt effect on U.S. GDP growth: -0.5 percentage point in Q1 - Direct effect from production suspension. U.S. GDP forecast revision: 2.0% to 1.5% - Barclays lowered its growth forecast due to Boeing. Expected production halt duration: through June - Base-case assumption used in the forecast. Post-recertification production estimate: 50 to 55 planes per month - Expected rebound in production after restart. China share of global tourism: 20% - Used to illustrate how Chinese travel disruptions could hurt destinations worldwide. Chinese visitor spending in the U.S.: about $20 billion in exports - Estimated annual export revenue from roughly 3 million Chinese visitors. Impact if Chinese tourism to the U.S. fell to zero for one quarter: about -0.4 percentage point of U.S. growth - Worst-case tourism shock estimate. Chinese tourists to the U.S.: about 3 million in 2019 - Used to estimate U.S. tourism exposure. Average spend per Chinese U.S. visit: about $7,000 - Spending assumption behind export estimate. Korean auto plants: assembly plant shutdowns reported - Example of supply-chain disruption from the virus. Iowa primary centrist vote share: above 50% - Gapin cites combined votes for Klobuchar, Biden, and Buttigieg as evidence not to overread Iowa.

Pivotal Quotes: "I think you're overstating the case." — Michael Gapin: Gapin’s response to Mellie’s warning that the three risks together could threaten the expansion. "Maybe slow has meant durable." — Jeff Mellie: Mellie’s argument that the U.S. economy has survived repeated headwinds without breaking. "We don't really see implications for US growth, certainly not beyond the first and second quarters." — Michael Gapin: Gapin’s view that coronavirus effects on U.S. growth should be temporary and limited.

Implications: The episode suggests investors should watch for compounded shocks rather than isolated events. Boeing, coronavirus, and political uncertainty may not individually trigger recession, but they could restrain investment, confidence, and short-term growth if they persist or worsen.
