Gold hit a 1-1/2 week low on Tuesday, heading for a fourth consecutive month of losses as a stronger dollar and rising US interest rates continue to weigh, pushing speculators to hold record short or sell positions. The dollar was flat versus a currency basket, following a three month streak of gains, with the US Federal Reserve set to reaffirm the outlook for further gradual rate rises at the end of its two-day rate review through Wednesday.
The US central bank has raised benchmark lending rates twice this year and signalled two more increases by year's end. Higher rates tend to boost the dollar, making dollar-priced gold more expensive for holders of other currencies.
"The increase in US interest rates so far has undermined a number of emerging market currencies. This general instability is seen as deflationary, and doubtless has encouraged (gold) speculators to take record short positions," said Alasdair Macleod, head of research at GoldMoney.com.
Spot gold fell 0.5 percent to $1,215.80 an ounce at 1319 GMT, having hit its lowest since July 19. The precious metal is heading for a fourth monthly decline that would mark its longest losing streak since 2013. US gold futures were 0.6 percent lower at $1,214.50 an ounce.
Hedge funds and money managers net short positions in COMEX gold stood at 27,156 contracts in the week to July 24, US Commodity Futures Trading Commission data showed on Friday, the biggest on records dating back to 2006.
In the wider markets, world stocks are set to end July with the best monthly returns since January, despite trade tensions, growth fears and a widespread sell off in the global tech sector. Rising equities tend to indicate investor appetite for risky assets as opposed to traditional safe havens like gold.
"As the US economy continues to do well and the perceived threat to the economy from the trade tensions appears low, we believe there is little incentive for US investors to enter the gold market at the current point in time," said Julius Baer in a note. "Investors remain absent. Stronger demand from China is offset by weaker demand elsewhere. We stick to our short-term neutral view as the market lacks a trigger for an imminent upward or downward move."
Spot gold is biased to fall into a range of $1,206-$1,214 per ounce, according to Reuters technicals analyst Wang Tao. Among other precious metals, silver slipped 0.6 percent to $15.34 an ounce, platinum rose 0.4 percent to $827.30 and palladium fell 0.1 percent to $927.80.
