<p>Basis risk, in the context of trading, refers to the possibility of loss due to the difference in performance between related but separate financial instruments. It arises when the correlation between these instruments deviates from expectations, leading to unexpected outcomes.</p>

<h2>How It Works</h2>
<p>Basis risk occurs when two or more related assets, such as a futures contract and its underlying asset, do not move in lockstep as anticipated. This can happen due to various factors, including changes in supply and demand dynamics, shifts in market sentiment, or differences in contract specifications.</p>
<p>For instance, consider a trader who buys a futures contract on wheat, expecting it to mirror the price of spot wheat. If the futures contract price moves differently due to factors like storage costs or seasonal fluctuations, the trader may face basis risk.</p>

<h2>Why It Matters for Traders</h2>
<p>Basis risk can significantly impact a trader's portfolio, leading to unexpected gains or losses. It matters for several reasons:</p>
<ul>
  <li><strong>Hedging strategies</strong>: Traders often use derivatives to hedge their positions. Basis risk can undermine these strategies, leading to losses instead of the expected protection.</li>
  <li><strong>Arbitrage opportunities</strong>: Basis risk can create arbitrage opportunities, allowing traders to profit from price discrepancies between related assets. However, it can also lead to losses if the arbitrage position moves against the trader.</li>
  <li><strong>Portfolio diversification</strong>: Basis risk can affect the diversification benefits of a portfolio. If correlated assets move differently due to basis risk, the portfolio's risk profile may change, potentially leading to higher overall risk.</li>
</ul>

<h2>Example</h2>
<p>Consider a trader using STB Provider's MetaTrader 5 platform to trade EUR/USD. The trader buys an EUR/USD futures contract, expecting it to mirror the spot price. However, if there's a sudden increase in demand for USD due to geopolitical risks, the futures contract may not move in line with the spot price due to basis risk. This could lead to unexpected losses for the trader.</p>
