* Finance Minister says fiscal position is solid
* Sees growth outpacing global average for years
* Says recent decline in commodities may not persist (Updates with comments, details, background throughout)
SAO PAULO, May 27 (Reuters) - The Brazilian economy will keep growing above the global average in coming years thanks to its solid fiscal position and efforts to keep inflation under control, Finance Minister Guido Mantega said on Friday.
Investment flows into Brazil, budget spending prudence and efforts to tame price increases in some goods and services will ensure solid growth "for years to come," Mantega said at an event.
Brazil needs to lure more capital spending to ensure sustainable growth around 4.5 percent in the long run. Investment including inventory changes should grow at least twice as fast as overall economic growth to keep Brazil free of inflationary pressures, Mantega said.
Mantega said recent gains in the Brazilian currency, the real BRBY, reflect "excess liquidity in global capital and financial markets." Efforts by policymakers to contain some of those gains have worked. he added. (Reporting by Jose de Castro; Writing by Guillermo Parra-Bernal; Editing by James Dalgleish)
