“Because REITs, MLPs, and BDCs are pass-through entities, the retained earnings pool mostly runs dry. To grow, these entities must issue either new equity or new debt. Rising interest rates raise the cost of both. If these pass-through entities have to tap capital markets, particularly for debt, their financing costs rise relative to their revenue and cash flow decreases, putting the indispensable dividend or distribution at risk,” adds ETF Daily News.

MLPs don’t make their money based on oil or gas prices. Unlike other energy sector stocks, MLPs primarily deal with the distribution and storage of energy products, so their business model is less reliant on the commodities market since MLPs profit off the quantity of oil and natural gas they are able to move around.
