swiss-finance-data

Python package for Swiss financial data — official sources, clean API

PyPI version Tests License Python

Why swiss-finance-data?

Accessing Swiss financial data in Python is fragmented. Existing tools focus on US/global markets and provide limited support for Swiss-specific datasets.

swiss-finance-data provides:

  • A unified, clean API for Swiss financial data
  • Official government data sources — no scraping
  • Extensible provider architecture
  • Long-term maintainability with a stable public API

It does not aim to replace global data providers such as yfinance, but to complement them for Swiss markets.

What's included

Module Data Source
SNB Policy rate, SARON monthly & daily Swiss National Bank
FX CHF exchange rates (9 currencies) Swiss National Bank
CPI Consumer Price Index, YoY inflation Swiss National Bank

Quick Start

from swiss_finance import SNB, FX, CPI, SMI, Bonds

# SNB Policy Rate
rate = SNB.get_policy_rate()
print(f"SNB Policy Rate: {rate}%")
# SNB Policy Rate: 0.5%

# SARON — CHF risk-free rate
saron = SNB.get_saron()
rf_daily = SNB.get_saron_daily() / 100 / 252  # daily risk-free rate
print(f"SARON: {saron}%")
# SARON: 0.52%

# CHF Exchange Rates
eur_chf = FX.get_rate("EUR")
print(f"EUR/CHF: {eur_chf}")
# EUR/CHF: 0.9321

# Swiss CPI and YoY inflation
inflation = CPI.get_inflation_yoy()
print(f"Inflation YoY: {inflation.iloc[-1, 0]:.2f}%")
# Inflation YoY: 1.10%

# SMI equities
prices = SMI.get_prices()
returns = SMI.get_returns(period="1y")

# Swiss Confederation bond yields
yield_10y = Bonds.get_yield("10y")
print(f"10y Confederation bond: {yield_10y:.2f}%")
# 10y Confederation bond: 0.85%

curve = Bonds.get_yield_curve()
