Global capital-expenditure boom and its foreign-exchange implications: Deutsche Bank sees a rare global capex boom supporting growth resilience and limiting scope for further dollar strength.

Overview

This FX blog examines why global growth has remained resilient and what that implies for currency markets. Deutsche Bank attributes the resilience to an unusually broad global capital-expenditure cycle and argues that this backdrop reduces the case for a sustained dollar breakout this year.

Core views

Deutsche Bank identifies growth as the “superglue” holding markets together: yields have risen largely because neutral rates have moved higher, equities remain close to record highs, credit spreads are tight, and cross-asset volatility is subdued. The report argues that these conditions are best explained by persistent growth resilience rather than a single-market effect. The institution traces that resilience to an unprecedented global capital-expenditure cycle. In its view, the cycle is supported not only by AI investment but also by government-financed efforts to build strategic autonomy across defence, energy, supply chains and other infrastructure. The report emphasizes that large capex booms are unusual: excluding post-World War II reconstruction, it identifies only the late 1980s and mid-2000s as other major episodes, and notes that the dot-com bubble does not rank among its top five. The historical comparison suggests that such booms are sustained multi-year developments. The top five post-war capex booms excluding the reconstruction period lasted three years on average. Deutsche Bank estimates that the present cycle could last five years under conservative assumptions and add 3% cumulatively to GDP; a more optimistic set of assumptions raises the contribution to 6%. Either outcome would make the current boom the second-largest post-reconstruction episode in its ranking, behind the 1946–1973 postwar/golden-age boom, which it sizes at 16%. The estimate is built from cumulative GDP contributions of 1.3% to 3.3% from AI, 1.4% to 1.8% from energy, 0.6% to 0.8% from defence, and 0.4% to 0.7% from other infrastructure, offset by 0.4% of crowding out in both scenarios. The report therefore contends that consensus forecasts may be persistently underestimating both the resilience and the less cyclical character of the current investment cycle, while global data surprises are on track for their strongest positive run on record. For foreign exchange, Deutsche Bank observes that the historical capex cycles in its comparison were accompanied by a very gradual dollar downtrend over their duration. Combining that precedent with the current growth outlook, its recent FX Blueprint calls for “calm in the storm” and rejects the case for a large dollar breakout for the remainder of the year. The report consequently says investors should not chase the dollar higher following the recent repricing.

Analysis framework

The report first links resilient growth to broad cross-asset market conditions, then identifies AI- and strategic-autonomy-led capital spending as the underlying driver. It compares the present cycle with historical post-war capex booms and uses conservative and optimistic component estimates to calculate potential cumulative GDP effects, before relating the historical dollar pattern during prior booms to its FX conclusion.

Methodology notes

• Other

  Historical ranking and comparison of post-war capital-expenditure booms

  The report ranks major capex episodes by size and compares their duration and dollar performance to place the current cycle in historical context.

• Other

  Baseline and optimistic scenario estimates for cumulative GDP contribution

  The institution sums estimated contributions from AI, energy, defence and infrastructure, then deducts crowding out, to frame a conservative 3% and optimistic 6% cumulative GDP outcome.

Asset mapping & comparison

• US dollar

  The report argues that historical capex booms coincided with a gradual dollar weakening and sees limited scope for a large dollar breakout this year.

  Weaknesses

  Recent dollar repricing should not be chased, according to the report.

  Comparison

  All capex cycles highlighted in the report's historical table saw the dollar gradually trend weaker through their duration.

Impact & implications

The report says the breadth and expected persistence of investment spending may keep global growth stronger and less cyclical than consensus assumes. In FX, it sees this environment as consistent with restrained dollar upside rather than a large breakout over the rest of the year.
