Tempo's tokenized financial product architect, Neira, highlights the macroeconomic significance of payment stablecoins, emphasizing the importance of reserve asset allocation rather than software layers. According to Foresight News, if reserves flow into bank deposits, it could restructure the banking system, while inflows into short-term government bonds may lower short-term yields. Data from the Bank for International Settlements indicates that each unit of net inflow can decrease the yield on three-month government bonds by 2.5 to 3.5 basis points. If reserves are held at central banks, it resembles 'narrow bank money.' In terms of cross-border payments, stablecoins essentially facilitate currency conversion, with the primary challenge being the pre-credit capacity of destination partners rather than on-chain settlement speed. Neira suggests that regulators should focus on reserve allocation and net issuance volume as key monitoring indicators, rather than market capitalization.
