How Disasters and Weather Affect Markets
How Disasters and Weather Affect Markets
Introduction: The Growing Importance of Climate Risk in Finance
Extreme weather events and natural disasters are no longer just news headlines — they’re critical factors driving market volatility, supply chain disruptions, and investment returns. From hurricanes disrupting oil production in the Gulf of Mexico to droughts affecting agricultural commodities in the Midwest, climate-related events are reshaping the financial landscape.
In this article, we’ll explore how to analyze these complex relationships using AxionQuant’s comprehensive SDK, combining financial data, ESG metrics, supply chain insights, and market sentiment to understand and predict weather-related market impacts.
The Market Impact Channels
- Supply Chain Disruptions
When disasters strike, they interrupt production facilities, transportation networks, and distribution channels. The 2011 Thailand floods, for example, cost global automakers and electronics manufacturers billions in lost production.
- Commodity Price Volatility
Extreme weather directly affects agricultural commodities (droughts), energy prices (hurricanes disrupting Gulf production), and industrial metals (flooding affecting mining operations).
- Equity Market Reactions
Insurance stocks, construction companies, agricultural firms, and energy producers all react differently to weather events. Some suffer losses while others benefit from recovery efforts.
Getting Started with Axion for Climate Risk Analysis
First, let’s set up our environment:
from axion import Axion, visualize, linearRegression, lstm
import pandas as pd
# Initialize client with your API key
client = Axion(api_key="your_api_key_here")Tutorial: Analyzing Hurricane Impact on Energy Markets
Let’s walk through a practical example examining how hurricanes affect oil companies and their supply chains.
Step 1: Gather Data on Affected Companies
# Get oil companies operating in hurricane-prone regions
energy_tickers = ['XOM', 'CVX', 'BP', 'RDS-A'] # Example tickers
# Fetch company profiles and supply chain data
company_data = []
for ticker in energy_tickers:
# Get company profile
profile = client.profiles.asset(ticker)
# Get supply chain data
suppliers = client.supply_chain.suppliers(ticker)
customers = client.supply_chain.customers(ticker)
# Get ESG risk scores (including climate risk)
esg_data = client.esg.data(ticker)
company_data.append({
'ticker': ticker,
'profile': profile,
'suppliers': suppliers,
'customers': customers,
'esg': esg_data
})Step 2: Analyze Historical Price Reactions to Past Hurricanes
# Define hurricane dates (example: Hurricane Katrina 2005)
hurricane_dates = {
'Katrina': '2005-08-23',
'Harvey': '2017-08-17',
'Michael': '2018-10-07'
}
# Get price data around hurricane events
price_analysis = []
for hurricane, date in hurricane_dates.items():
for ticker in energy_tickers:
# Get 60 days of price data before and after hurricane
prices = client.stocks.prices(
ticker=ticker,
from_date=pd.to_datetime(date) - pd.Timedelta(days=60),
to_date=pd.to_datetime(date) + pd.Timedelta(days=60)
)
# Calculate impact metrics
pre_hurricane_return = calculate_returns(prices, 'before')
post_hurricane_return = calculate_returns(prices, 'after')
volatility_change = calculate_volatility_change(prices, date)
price_analysis.append({
'hurricane': hurricane,
'ticker': ticker,
'impact': post_hurricane_return - pre_hurricane_return,
'volatility_change': volatility_change
})Step 3: Visualize Supply Chain Vulnerabilities
# Create supply chain network visualization
def visualize_supply_chain_risk(ticker):
suppliers = client.supply_chain.suppliers(ticker)
customers = client.supply_chain.customers(ticker)
# Process data for visualization
nodes = []
links = []
# Add central company
nodes.append({'id': ticker, 'group': 1, 'size': 20})
# Add suppliers
for supplier in suppliers[:10]: # Top 10 suppliers
nodes.append({'id': supplier['name'], 'group': 2, 'size': 10})
links.append({'source': supplier['name'], 'target': ticker, 'value': 5})
# Add customers
for customer in customers[:10]: # Top 10 customers
nodes.append({'id': customer['name'], 'group': 3, 'size': 15})
links.append({'source': ticker, 'target': customer['name'], 'value': 5})
# Create network graph (using Plotly)
visualize.graph_network(nodes, links, title=f"{ticker} Supply Chain Network")Step 4: Predictive Modeling for Future Events
# Use machine learning to predict impact of future hurricanes
def predict_hurricane_impact(ticker, hurricane_category, affected_region):
# Get historical data
historical_prices = client.stocks.prices(ticker, from_date='2010-01-01')
# Get historical hurricane data (would integrate with external dataset)
hurricane_history = get_hurricane_history() # External function
# Prepare features: hurricane strength, company exposure, season, etc.
features = prepare_hurricane_features(historical_prices, hurricane_history)
# Use LSTM model from Axion SDK
predictions = lstm(
df=features,
x='date',
target='price_change',
features=['hurricane_strength', 'company_exposure', 'seasonal_factor'],
n_preds=30 # Predict 30 days ahead
)
# Visualize predictions
visualize.line(predictions, x='time', y='price_change',
title=f"Predicted Impact on {ticker}")
return predictions
# Run prediction for hypothetical hurricane
prediction = predict_hurricane_impact('XOM', category=4, affected_region='Gulf of Mexico')Step 5: Integrated Risk Dashboard
def create_climate_risk_dashboard(tickers):
fig = make_subplots(
rows=2, cols=2,
subplot_titles=('Price Impact', 'Supply Chain Risk',
'ESG Climate Scores', 'Sentiment Analysis')
)
for i, ticker in enumerate(tickers):
# 1. Price impact analysis
prices = client.stocks.prices(ticker, from_date='2023-01-01')
fig.add_trace(
go.Scatter(x=prices['time'], y=prices['close'], name=ticker),
row=1, col=1
)
# 2. Supply chain concentration risk
suppliers = client.supply_chain.suppliers(ticker)
risk_score = calculate_concentration_risk(suppliers)
fig.add_trace(
go.Bar(x=[ticker], y=[risk_score], name='SC Risk'),
row=1, col=2
)
# 3. ESG climate risk
esg = client.esg.data(ticker)
fig.add_trace(
go.Indicator(
value=esg['climate_risk_score'],
title={'text': "Climate Risk"},
domain={'row': i, 'column': 3}
),
row=2, col=1
)
# 4. News sentiment around climate events
news = client.news.company(ticker)
sentiment = client.sentiment.all(ticker)
fig.add_trace(
go.Scatter(x=sentiment['date'], y=sentiment['score'], name='Sentiment'),
row=2, col=2
)
fig.update_layout(height=800, showlegend=True)
visualize(fig)Advanced Analysis: Correlation Between Weather Events and Market Volatility
# Analyze correlation between temperature anomalies and commodity prices
def analyze_weather_commodity_correlation():
# Get climate data (example using economic data API)
climate_series = client.econ.search("temperature anomaly")
temp_data = client.econ.dataset(climate_series[0]['id'])
# Get agricultural commodity prices
corn_prices = client.futures.prices("ZC=F", from_date='2010-01-01')
wheat_prices = client.futures.prices("ZW=F", from_date='2010-01-01')
# Merge datasets
merged_data = merge_datasets(temp_data, corn_prices, wheat_prices)
# Calculate correlations
corr_matrix = merged_data[['temperature', 'corn_price', 'wheat_price']].corr()
# Visualize correlation heatmap
visualize.cov(corr_matrix)
# Regression analysis
regression_result = linearRegression(
df=merged_data,
x='temperature',
target='corn_price',
n_preds=12,
scale='M'
)
return regression_resultKey Insights for Investors
