In short: both can serve as an emergency fund, but they have important differences in guarantees, how they\u2019re marked to market, and redemption conditions that affect safety and convenience.<\/p>\n<p>Below I explain step by step how to compare each aspect \u2014 without recommending any specific institution or product \u2014 and provide a checklist and a comparison table to help your decision.

Some banks advertise daily liquidity, but availability for withdrawal may occur on the next business day or require an internal transfer.<\/li>\n<li><strong>Check the guarantee<\/strong>: Tesouro Selic is guaranteed by the National Treasury; a CDB depends on the issuer\u2019s solidity and, up to certain limits, the coverage of the Fundo Garantidor de Cr\u00e9ditos (FGC). Consult the FGC\u2019s official page to understand current limits and rules.<\/li>\n<li><strong>Assess credit risk<\/strong>: for CDBs, review the issuer\u2019s ratings and financial statements; for government bonds, the risk is sovereign in nature. Avoid concentrating your entire emergency fund with a single issuer.<\/li>\n<li><strong>Consider marking to market<\/strong>: Tesouro Selic is subject to marking to market if sold before maturity, which can cause a small loss in specific moments; CDBs with daily liquidity generally offer an agreed redemption value, but contractual conditions may vary.<\/li>\n<li><strong>Compare costs and taxes<\/strong>: both are subject to Income Tax and possibly IOF on very short-term redemptions; custody fees, brokerage or bank charges can reduce net return. Check official pages for up-to-date rules.<\/li>\n<li><strong>Test the operation<\/strong>: open an account at a broker or bank and simulate investing and redeeming. Use the Tesouro Direto yield simulator to check practical examples.<\/li>\n<\/ol>\n<h3><span class=\"ez-toc-section\" id=\"Quick_checklist_before_investing\"><\/span>Quick checklist before investing<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<table>\n<thead>\n<tr>\n<th>Item<\/th>\n<th>Question<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Liquidity<\/td>\n<td>Redemption in D+0 or D+1?
