UKL20: Shrinking the Financial Sector (1980-2060)


 


A 2026 change in leadership in the United Kingdom (UK) triggered by a no-confidence vote, brings up the issue of what policies might be expected from the new Labor Government, potentially headed by Andy Burnham, champion of the Green New Deal UK. One of the core goals of the Green New Deal UK (see Notes below), based on analogies to the 1930s New Deal in the US, is to restructure the UK Financial Sector.


In this post, I am going to present an index of UK Financialization (FINZ) and how it might be affected by various Geopolitical Alignments as a result of Brexit, Britain leaving the European Union (EU).

The graphic above shows five possible Geopolitical Alignments and how they might affect the FINZ1 index (see Notes below, the growth component). Business-as-Usual (BAU) creates unlimited growth in the Financial Sector while other alignments (a Random Walk, RW, the US, the World System, W, and the EU) stabilize or contract the Financial Sector. The biggest contraction comes from alignment with the EU, which may have been another motivation for Brexit.

Spain: Growth Forecasts (1980-2100)


July 8 2026 Trump Lashes Out at Spain: ‘Cut Off All Trade.’ Here’s Why That’s Unlikely.

The New York Times article (above) argues that Trump Trade threats are unlikely to have much effect on Spain (ES). Spain is a member of the European Union (EU) and is subject to EU agreements about trade. If the Trump Administration violated these agreements, there would be an EU-wide negative reaction, possibly a Trade War.

One way to validate this conclusion is to look at various Geopolitical growth forecasts for Spain (ES1 in the graphic above). Alignment with the US or the World System (W) is not much better than a Random Walk (RW). Business-as-Usual (no Geopolitical Alignment) either with Technological Learning-by-Doing (BAU or without  (ES2-3) provides a middle-ground. Unlimited Exponential Growth is forecast as the result of alignment with the EU.

Spain should not be and is not worried about Trade Shocks from the US and Trump threats will have little impact.

You can run the ESL20 model yourself using R-code here. For more of my posts see the Blog Roll: Spain. For information about how the ESL20 model was constructed and data sources, see the Boiler Plate and Dynamic Component Models.

Notes


ESL20 Measurement Model


The Growth Component (ES1) is a relatively equal weighting of all the indicators (CO2 Emissions, Energy Use, GDP, Labor Force, Population, Unemployment, Ecological Footprint, KOF Globalization Index and the Human Development Index). The other two components (ES2 and ES3) are Historical Feedback Controllers.

Switzerland (1960-2100) Population Forecasts

 



June 14, 2026 Switzerland Rejects Measure to Cap Its Population at 10 Million from the NY Times. The referendum was about limiting migration after the number of residents rose by more than a quarter since 2000, but it was framed around affordability and sustainability.

The Population Cap (solid red line in the graphic above) proposed for Switzerland will not automatically be reached by any of my forecasting models, although the stable Business-as-Usual (BAU) model (see below) might eventually reach a steady state at a level lower than 10 Million after 2100. 

The best forecast (using the Akaike Information Criterion) is the CH_LM (Late Modern) model driven by Western Europe (WE, the dashed red line in the graphic above, state-space model presented below). However, linking to the EU (see below) breaks the Population cap around 2030. Notice that linking to the US leads to Population collapse.

For more information about Switzerland, view the Blog Roll: Switzerland. The video at the beginning of the Blog Roll explains why, even though the Population Cap referendum failed, it will keep coming up in the future and will probably pass at some point.

The forecasts at the beginning of this post show the Geopolitical cross-pressures Switzerland is under. Germany (WE, Western Europe) and the US are Switzerland's largest trading partners (see the DE_LM model below, which also leads to Population collapse). On the other hand, Switzerland is "highly developed free-market economy, ranked first in the world since 2015 on the Global Innovation Index (Wikipedia, see below)". To limit Population (without the cap) it could well chose to "go it alone" with the BAU model. 

It is also interesting that the Population cap, pushed by the right-wing Swiss People's Party, serves Environmental goals. 


Using the Kaya Identity, Population Stability (N) would stabilize CO2 Emissions and, ultimately, Global Temperature (T). Eventually, these two forces may come together and create a Steady-state Economy in Switzerland.

AIC Statistics


All of the Akaike Information Criterion (AIC) Statistics have values in the 800 range except for the RW Model (Random Walk), which is best in the short-term (year-to-year).


CH_LM Western Europe Input


The CH_LM Model (WE, Western Europe Input) is stable and  provides the best Attractor Path, but it breaks the 10 million Population cap around 2030. From ChatGPT:


Switzerland, since it is not an EU member, is not obliged to accept migration from other EU members or link it's population to the EU




CH_LM BAU Model


The BAU model is stable and reaches a steady state after 2100 below the 10 million Population Cap.

CH_LM US Input




The CH_LM US Input model is stable but leads to population collapse with strong negative forces from the US Feedback components, US2 and US3.

CH_LM_N Model with DE_LM input


The CH_LM_M DE Input model is unstable and leads to population collapse in Switzerland.

East-Asia Pacific: Alternate Futures

 


May 15, 2026 Trump-Xi summit ends on cordial note but no breakthroughs ... - CNN

President Trump seems attracted to the old idea of Spheres of Influence when pursing Geopolitical Alignments. Critics argue that the idea is useless, at least for the US and China in the 21st Century. But President Trump presses ahead, leaving Europe and NATO while focusing more directly on Latin America. The idea seems to be that China's Sphere of Influence would naturally be the East-Asia Pacific Region (EAP). In this post, I use the EAP_L20 Model to ask what type of Geopolitical Alignment (if any) would be best for the people of the Indo-Pacific.

All of the Geopolitical Alignments for the EAP Region are unstable (except with China) while alignment with China (CN) produces rapid growth-and-collapse out to 2100.


In other words, allowing CN to assert it's Sphere of Influence over EAP would produce growth and stability benefits for the Indo-Pacific. China, however, does not seem to be interested.
