my heart goes out to all Venezuelans right now. Their poorly run government pretty much bet the entire farm on oil and with the depreciation in recent years it was already tough living there. At a price close to 0, it can not be good.
That aside, their monetary policy has also been a train wreck from the 70's, and compounded with more bad decisions in the early 2000's. https://mises.org/wire/venezuelas-economic-collapse-was-enab...
Until they fix core issues in their central government/bank, they will continue to struggle in a global economy.
