tidyBdE is an API package that helps to retrieve data from Banco de España. The data is provided as tibble and the package tries to guess the format of every time-series (dates, characters and numbers).

Search series

Banco de España (BdE) provides several time-series, either produced by the institution itself or compiled for another sources, as Eurostat or INE.

The basic entry point for searching time-series are the catalogs (indexes) of information. You can search any series by name:


# Load tidyverse for better handling

# Search GBP on "TC" (exchange rate) catalog
XR_GBP <- bde_catalog_search("GBP", catalog = "TC")

XR_GBP %>%
  select(Numero_secuencial, Descripcion_de_la_serie) %>%
  # To table on document
Numero_secuencial Descripcion_de_la_serie
573214 Tipo de cambio. Libras esterlinas por euro (GBP/EUR).Datos diarios

Note that BdE files are only provided in Spanish, for the time being, the organism is working on the English version. By now, search terms should be provided in Spanish in order to get search results.

After we have found our series, we can load the series for the GBP/EUR exchange rate using the sequential number reference (Numero_Secuencial) as:

seq_number <- XR_GBP %>%
  # First record
  slice(1) %>%
  # Get id
  select(Numero_secuencial) %>%
  # Convert to num

#> [1] 573214

time_series <- bde_series_load(seq_number, series_label = "EUR_GBP_XR") %>%
  filter(Date >= "2010-01-01" & Date <= "2020-12-31") %>%

Plot series

The package also provides a custom ggplot2 theme based on the publications of BdE:

ggplot(time_series, aes(x = Date, y = EUR_GBP_XR)) +
  geom_line(colour = bde_vivid_pal()(1)) +
  geom_smooth(method = "gam", colour = bde_vivid_pal()(2)[2]) +
    title = "EUR/GBP Exchange Rate (2010-2020)",
    subtitle = "%",
    caption = "Source: BdE"
  ) +
    xintercept = as.Date("2016-06-23"),
    linetype = "dotted"
  ) +
    x = as.Date("2016-06-23"),
    y = .95,
    label = "Brexit"
  )) +
  coord_cartesian(ylim = c(0.7, 1)) +

The package provides also several “shortcut” functions for a selection of the most relevant macroeconomic series, so there is no need to look for them in advance:

gdp <- bde_ind_gdp_var("values")
gdp$label <- "GDP YoY"

UnempRate <- bde_ind_unemployment_rate("values")
UnempRate$label <- "Unemployment Rate"

plotseries <- bind_rows(gdp, UnempRate) %>%
  drop_na() %>%
  filter(Date >= "2010-01-01" & Date <= "2019-12-31")

ggplot(plotseries, aes(x = Date, y = values)) +
  geom_line(aes(color = label)) +
    title = "Spanish Economic Indicators (2010-2019)",
    subtitle = "%",
    caption = "Source: BdE"
  ) +
  theme_bde() +
  scale_color_bde_d() # Custom palette on the package

A note on caching

You can use tidyBdE to create your own local repository at a given local directory passing the following option:

options(bde_cache_dir = "./path/to/location")

When this option is set, tidyBdE would look for the cached file on the bde_cache_dir directory and it will load it, speeding up the process.

It is possible to update the data (i.e. after every monthly or quarterly data release) with the following commands:


# On most of the functions using the option update_cache = TRUE

bde_series_load("SOME ID", update_cache = TRUE)
