Normally, moderate inflation follows the path of the deficit with a relatively large delay, because economic agents are unable to anticipate deficit values and monetization with precision. On the other hand, in times of hyperinflation, inflation anticipates the deficit (economic agents overestimate new monetization policies and there is a universal tendency to evade local currency). In Venezuela, we can see that since 2013 (graph 3) inflation has increased at a faster rate than the deficit, and for this reason we can consider the country in a state of hyperinflation as of that date.
This creates a big problem for the government of Venezuela due to the fact that real tax revenues decrease (just as in all cases of hyperinflation). During the time between receipt of tax revenues and actually putting these taxes to use, inflation eats up the real value providing the government with less real revenue.
An inverse relationship exists between inflation in Venezuela and crude oil prices (graph 4). This relationship is such that inflation increases rapidly when the main source of government revenue (revenue from oil) decreases due to the fact that the government does very little to reduce costs when decreases in revenues are experienced (thus deficits are monetized and amounts of currency rise at aggressive rates).
