What does bolstering mean?
"Bolstering" is the present participle and gerund of the verb "bolster," meaning to support, strengthen, or reinforce something — either physically or figuratively. The word takes its name from the bolster, the long, firm cushion traditionally placed under pillows on a bed; just as a bolster props up a sleeper, to bolster something is to prop it up against weakness or decline. Today the word is used overwhelmingly in its figurative sense: governments bolster economies, coaches bolster morale, evidence bolsters an argument, and companies bolster their reputations. It carries a distinctly positive connotation, implying active, deliberate support of something that already exists, and it is especially common in formal writing such as news reports, policy documents, and business communication. Related phrases include "bolstering confidence," "bolstering support," and "bolstering the economy." Because it suggests reinforcement rather than creation, "bolstering" pairs naturally with talk of fragile or struggling things being made stronger.
Present participle of "bolster": to strengthen, support, or prop up something physically or figuratively.
"New tax incentives are aimed at bolstering small businesses in the region."
Most often used figuratively in modern English; the literal, physical sense is now relatively rare.
As a gerund, the act or process of providing support or reinforcement to something.
"The steady bolstering of consumer demand helped pull the economy out of recession."
Typically appears in formal or analytical writing when describing an ongoing process of reinforcement.
Before it meant moral support, a bolster was literally the fat cushion you sleep on — English borrowed the idea of 'propping things up' straight from bedding.

Etymology of bolstering
"Bolstering" derives from "bolster," which comes from Old English "bolster," meaning a bed cushion, from Proto-Germanic roots related to dwelling or swelling padding. Cognates survive in other Germanic languages, notably German "Polster," meaning cushion. By the 16th century, English speakers had extended the word metaphorically from physical cushions to anything that supports or strengthens, giving rise to the verb "bolster" and, in turn, "bolstering."
