Interest Rate Differentials: Differences in interest rates between Thailand (THB) and India (INR) drive capital flows affecting relative currency demand.

Economic Growth: Stronger economic growth in Thailand versus India typically strengthens the THB relative to the INR, and vice versa.

Inflation Rates: Higher inflation in Thailand compared to India weakens the THB, as it erodes purchasing power, causing depreciation.

Trade Balance: A trade surplus in Thailand relative to India may strengthen the THB due to increased demand for THB to purchase Thai exports.

Political Stability: Political instability in either Thailand or India can create uncertainty and capital flight, weakening the respective currency.

Central Bank Intervention: Actions by the central banks of Thailand or India to manage exchange rates can directly influence the THBINR rate.

Risk Appetite: Global risk appetite impacts emerging market currencies; during risk-on periods, the THB and INR might strengthen, whereas risk-off periods may lead to weakening.

Commodity Prices: Thailand and India's import/export balances of key commodities can influence their currencies.
