Understanding the LKR/SGD Exchange Rate
The LKR/SGD exchange rate tells you how many Singapore dollars you get for 1 Sri Lankan Rupee.
This is the mid-market rate — the real exchange rate without any markup. It's the same rate used by Google Finance.
AllRatesToday provides this rate via a free REST API, updated every 60 seconds from institutional interbank market data.
Integrate live LKR/SGD rates into your app with our official SDKs for JavaScript, Python, PHP, and React.
The exchange rate between LKR and SGD fluctuates based on supply and demand in the foreign exchange market.
Economic data releases, central bank announcements, and geopolitical events can all cause significant movements in the rate.
Currency converter API for LKR to SGD
This converter is a thin layer over two APIs. Both return JSON, both take one
HTTP call, and both have a free tier — no credit card.
Mid-market exchange rate API
The live interbank midpoint — the number shown above. It moves continuously
and is refreshed every 60 seconds across 160 currencies.
Use it for pricing, checkout, display and anything a customer sees.
The rate a named institution actually published for a given date, from
116 central banks and 3 tax
authorities. Unlike a mid-market rate it never changes after publication,
which is what tax filings, customs valuations and audits require.
Any past date — /central-bank/{bank}/2026-06-30. If the bank did not publish that day you get the most recent prior date, flagged.
Every bank at once — /api/v1/central-banks/rates returns all sources for one pair, so you can compare what each institution published.
Nothing is guessed — pairs a bank does not print are cross-computed from that bank's own table and returned with "derived": true and the method used. Banks are never mixed.
An MCP server — @allratestoday/mcp-server — lets Claude, Cursor and other MCP clients pull these rates directly, no glue code.
Free tier
300 requests, no credit card, no trial expiry. Paid plans start at €4.99/month for 5,000 requests a month.
Which one do you need? If a regulator, tax authority or auditor
names the source, use the official rate — the two can differ by several percent
on the same day. For everything a customer sees, use the mid-market rate.
On weekends and holidays the official endpoints return the most recent published
date, which is the figure compliance rules expect you to apply.
Official LKR and SGD Central Bank Rates
The rate on this page is the live mid-market rate. For tax filings, customs valuations, audits, and
compliant invoicing you often need the official reference rate published by the central bank instead.
AllRatesToday also serves published central-bank rates as JSON, with history and a free latest-rates tier.
Exchange rates are determined by supply and demand in the global foreign exchange (forex) market,
the largest financial market in the world with over $6 trillion traded daily.

meaning their value is determined by market forces. Some currencies are pegged to another currency (usually USD) at a fixed rate.

The mid-market rate shown on this page is the midpoint between these two prices.

Major economic announcements, interest rate decisions, and geopolitical events can cause significant moves in either direction.
